an equation is an statement which compares either 2 or more unknowns with known values which is separate by two sides with an equal sign, which means that it could be solved or simplified .
ReplyDeletejust by the word equa-tion it is showing that 2 statements when compared are equal
ReplyDeletea term i think is used to describe a particular quantity thats my opinion could be wrong until proven otherwise lol
ReplyDeletean expression cosist of known values and unknown variables related arithmetically(+-/*).An equation consist of expressions which are equal to each other,this equality is denoted (represented)by =
ReplyDeleteBW,I believe maths is the study of patterns and that the symbols and operations in mathematics are the components of the languages used to do so
ANY ONE WANTS TO DISCUSS ?
An equation has an equal sign (=) and also shows the how terms are connected by grouping them together and their relationship,and the results are known.
ReplyDeleteYes, Math is the study of patterns and symbols. There are patterns such as a constant increase and decrease in resulting numbers also the way in which a particular type of term can repeat itself in an equation or expression
ReplyDeletean equation is a mathematical statement that include variables connected together by a function and is equal to something
ReplyDeletea term is could simple be described a part or a specific variable in a mathematical statement
ReplyDeletethe connectors in an equation are functions that form a relationship between the varibles
ReplyDeletean exprresion is a mathematical statement that doesn't have a relationship because it is not equal to something
ReplyDeleteCAN ALL EQUATIONS BE SOLVED
ReplyDeleteI'm thinking all equatioms can be solved ,but then i remember while learning about graphs that the gradient of a vertical line is undefined,e.g. if the gradient is equal to 6/0,which has me thinking well what if you tried to solve an equation and that was the result ,e.g.x=6/0 (undefined)is the equation considered solved.
ANYONE WANTS TO DISCUSS
an equation is the one that can be solved be it has a relationship and can be equal to something. an expression on the other hand cannot be solved only simplified because it doesn't have a relationship because it is not equal to something
ReplyDeleteA term in mathematic,to me ,is any symbol that represents known or unknown numerical value. Now these numbers represent nouns(people,places animals or things),but the terms are only used to represent quantity(how much of whatever)
ReplyDeleteNOTE* WHEN I'M TRYING TO COMMUNICATE A POINT THIS IS HOW I SPEAK ,THESE ARE MY WORDS
An equation can be defined as a mathematical statement that two expressions, be it unknown or known values, are equal.
ReplyDeleteIn the case of mathematics, a term may be defined as an expression used to relate a particular value , whether known or unknown, to another
ReplyDeleteCAN ANYONE in M.E.T post me what we were supposed to write abouit for life skills ,thed 1500 word essay
ReplyDeleteConnectors in an Equations are things like the plus (+) sign, minus (-) sign, multiply (x) and divide (/) signs
ReplyDeletean equation is a direct comparison or relationship of two or more terms and as such, shows their product.
ReplyDeletean expression is a statement saying how two or more terms may be connected but doesn't state its product if connected in this way.
a term is a representation of something that has value, whether known or not. terms are the base foundation of expressions an equations

ReplyDeleteAn expression may be defined as a group of symbols that make a mathematical statement. They have no valuable use, but are used mainly to show how things are connected
ReplyDeletean equation can be solved but not an expression. this is so because an expression says how it MAY be connected but doesn't know or have a value. an equation knows the DIRECT OUTCOME (answer if solved) as its terms are DIRECTLY COMPARED/RELATED...see previous comment
ReplyDeleteAn equation can be solved, but an expression cannot. An expression, as defined before, only shows how mathematical terms are connected,whereas and equation has an equal sign, which allows it to be simplified or solved, because unknown values can be related to real values, across the equal sign
ReplyDeletethe connections in an equatiion are the signs +,-,x and or /(divide). the X can be replaced by brackets () and the divide can be replaced by what looks like the term being underlined ___
ReplyDeleteCAN ALL EQUATIONS BE SOLVED (@ michael.a.vincent)
ReplyDeleteIn maths, the slope or gradient of a line describes its steepness or incline. A higher slope value indicates a steeper incline.
the vertical line has no slope,eg)what is the slope of a high building? Since the building is built correctly,it has no slope, othrwise it will fall.
gradient = change in y / change in x
since its a line, two points can be obtained. A (X1, Y1) and B (X2, Y2)
since its a vertical straight line, the coordinates of X are the same. so it would be (Y1 - Y2) / 0 = infinite.
No, i don't believe all equations can be solved, mainly because, they can have unknown values on either side of the equation, which may only all for simplification, for example: a+b = c+d; it is an equation, as it contains an equal sign, but does not contain real values to allow for solving it.
ReplyDeleteHmm....a real life scenario to form an equation...that gonna be a little tricky
ReplyDeleteI hope by reading that ppl here can unders what michael was saying in my point of view although its an equation and we all say equations hav an = sign and an answer. I guess in this situation there can be some kind of understanding that there isnt really an answer and if there was i dont know what it would be at my intellectual level right now....

ReplyDeleteAye cheez...wah bout this for a real life equation. Adam buys 5 Pirate DVD's and 5 Bootleg CD's from a music cart for $75. Eve buys 12 Pirate DVD's and 14 Bootleg CD's from the same music cart for $190...how much does 1 Pirate DVD and one Bootleg CD cost??
ReplyDeletehahahahaha!!!! Thats a good one RaWr....therefore the equation will be:
ReplyDeleteLet X represent price of Pirate DVD
Let Y represent price of Bootleg CD
5X + 5Y = 75
14X + 12Y = 190
i think all equations can be solved since there is an equal sign then therfore there must be an answer it might not be a number but it can be anything which can represent an outcome from the equation.
ReplyDeleteThis comment has been removed by the author.
ReplyDeletean expression connects terms by using the functions either '+', '-', or a combination of both of these. it has no valuable use really but reflects how the various terms are connected.
ReplyDeletea term is a number or a variable or the product of both. it is separated from other terms in the expression or equation by the operators plus(+) or minus(-).
ReplyDeletean equation is an expression that can be equated to some answer. eg.5x + 5 = 20.
ReplyDeleteequations allow us to solve mathematical problems
equations are used to show that two expressions are exactly the same in value. also you may note that in equations, terms can be added to, subtracted from, multiplied to, and divide both sides. (what is done on one side of the equation must also be done on the other side)
ReplyDeletei think that all equations can be solved. in the case of dividing by zero, an answer still exists.maybe the only problem is that we humans don't really have a method of actually arriving at a value for the answer. but technically, an answer still exists...what do you all think about this???comments plz...
ReplyDeletethe connectors/functions/operators of an equation are plus(+) and minus (-)
ReplyDeletein a certain university,students who were absent for more that 20% of the term were each fined at the end of that term. in a certain class, 120 students, i.e. 70 females and 50 males, were found guilty of this offence and total fine of $8850 was collected. in another class, 85 students,i.e. 40 females and 45 males, were guilty. a fine of $6355 was collected at the term's end.
ReplyDeletewhat are the equations in this situation?
what is the fine for each male?
what is the fine for each female?
on the other hand, does division by zero mean that you are not actually dividing at all and that the answer is really the dividend???
ReplyDeletebecause...ok, look at it this way. another way to get the value of a division is by subtracting the divisor until the remainder is less than the divisor. eg. say...23/5. 23 - 5=18 (1), 18-5=13 (2), 13-5=8 (3), 8-5=3 (4). three is smaller than the divisor,five,right? so therefore the answer is 4 remainder 3. but in the case of zero, u will never ever get the remainder to be less than zero! so...the answer will always be the term being divided...any views on this???
ReplyDeletea value divided by o has a value it just approaches o but is not o and is a real number..
ReplyDeletethere are more than just + and - for connectors there are * ,/, and brackets which says to expand and also functions which relate values and expressions to each other.
ReplyDeletecan you explain?
ReplyDeletethe question is not operators i.e. things which we can use to carry out operations but connectors, which connect...therefore i dont think * and / can be connectors...they are operators,yes, but not really connectors.
ReplyDeleteFor bornagain16 question the answers are:
ReplyDelete1) the equations are using m for males and f for females.
70f+50m=8850.......1
40f+45m=6355.......2
using substitution
eq 1 will now be
m=8850/50 -70f/50....3
m=177-70f/50...3
now sub 3 into 2
40f+ 45(177-70f/50)=6355
40f+7965-3150f/50=6355
40f-63f=6355-7965
-23f=-1610
f=$70.00
subbing f as 70 into 1
70(70)+50m=8850
4900+50m=8850
50m=8850-4900
50m=3950
m=$79.00
therefore fine for males=$79.00
and females =$70.00
the functions which relate to each other simply mean that there are functions that are given for example when solving an equation to find the gradient of a curve and it is found the question then go further by asking if another curve, where no details are given excepting that it is an inverse function of the same curve of has a shift or an expansion or compression and to find the point of intersection of the two curves...
ReplyDeleteok the answers to the question are correct...but i dont really understand what ur trying to say in the last comment about the functions and the curves and stuff...please elaborate...
ReplyDeleteThis comment has been removed by the author.
ReplyDeleteok to bornagain16
ReplyDeletethis may be a lil bit complicated so bear with me
lets look at the fraction 1/2 and 1/3 which is bigger?
we all know that 1/2 is bigger and lets go further 1/1
1/1 is bigger than 1/2
so the trend is as the denominator gets smaller the larger the value.
for example 1/.5=2
1/.05=20
see the answer gets bigger and bigger
so as we approach 0 as our denominator we say we approach infinity cause the number get way too large
that is my opinion
ok... the functions are equations except that they have f of x which relates to an equation. the equation is 4x squared+2. the function might say that the next curve which intersects with the first one is the same curve with an stretched by 2 , therefore there would be new starting point and end points .
ReplyDeleteohhh...i see now...thanks for that explanation...didnt see it that way...but still,that dosent mean that there is no value, does it?the number is way tooo large but still,there is still a NUMBER...
ReplyDeleteyes cap_guy as from one superhero to another .. as the denominator decreases the closer it gets to infinity like the gradient of the y axis and log x and e to the x.. i think
ReplyDeleteyes but remember we cannot pin point that exact value so we have been taught to say this value is undefined. but that is the explanation.
ReplyDeletelantern, actually, the + 2 means that the entire graph is raised by two ,i.e. if a certain point had a y - value of 3, the new value would be 5...
ReplyDeleteyes green lantern the super hero is correct.
ReplyDeleteas these lines go vertical they tend to infinity
so we say their gradients are undefined
but note tho this is not the same for the horizontal of those graphs (logx and e to the x)
that gradient is zero
thats wat i was saying...the number is enormous, but there is still a value...we just dont have a method of finding it yet...
ReplyDeleteyes, similar yet different cases.
ReplyDeleteok well then in this case very interesting question...
ReplyDeletetell me does this question have an answer?
WHAT IS THE BIGGEST NUMBER?
hmmm...food for thought really...i guess the biggest number would actually be the biggest number divided by zero...what u think?
ReplyDeletethe largest number with a name excepting for infinity is a Googolplex this is a 1 with a Googol (1 with 100 zeros afer it).
ReplyDeletebut then tell me can't i just add 1 to that number and get a bigger number???
ReplyDeleteno it is the larget number that has a name if you add a 1 and a 101 zeros after it then what would you call it there is no name so it cannot be a number that can be questioned..
ReplyDeleteoh exactly my point you cannot really safely say it is the biggest number.
ReplyDeleteyou can just say it is undefined.
cause i believe numbers have no end
they keep going on and on and on......
that is true because just the fact that you are able to add another one to that number googolplex means that it cannot possibly be the largest number.and what is stopping you from adding another one and another and another and another?
ReplyDeletelol
ReplyDeletehahah
exactly my point that is why i said that number tends to INFINITY
what is infinity then?
i believe it just mean without end
yup...so back to the original question...can all equations be solved?
ReplyDeletehmmmmmmmm
ReplyDeleteyes i think so
cause i believe an equation is a statement
it says one side HAS to be equal to the other by what ever means.
so at the end what you are saying is if the answer
ends up being a number divided by zero can't you just say undefined????
it still is an answer
might not be as simple as you might like
or but i am not to sure about how correct this ming be can you say the answer is infinity?
I think that an equation have variable which are connected and that the statement show how they are the same .As a result it can be solved which means that there would be a output .
ReplyDeletePlease correct me if i am wrong
JUST adding to the above ,I think that if a statement contains an equal sign that does not make it an equation .
ReplyDeleteFor example:
y = 10
the fact that it is an equation means that it must have a value...in the zero case, it just means that the value is, unfortunately, undefined,or as cap said, infinity.it still is a value,although kinda vague but we cant really change that...
ReplyDeletecobra,in that case, 10 is the value of y.an expression contains two or more terms being equal to something
ReplyDeleteyes bornagain is correct you need connectors such as +-*and divide.
ReplyDeletey=10
is not an equation it is a value
sorry i meant "equation"...not expression.

ReplyDeletewe need more questions!!!
ReplyDeleteThis comment has been removed by the author.
ReplyDeleteAn equation is a mathematical statement written in numbers/variables and symbols and having two sides connected by an equal sign. The equal sign tells you that the amount represented by all the numbers and symbols on the left is the same as the amount represented by those on the right.
ReplyDeleteA Term I think is part of an algebraic equation, it can a number, a variable or the production of several numbers and variables, they are usually separated by an addition or subtraction sign.
ReplyDeleteConnectors in an equation are symbols which show the relationship between each term in the equation.
ReplyDeletesigh needs to move on to trigs...
ReplyDeleteAn expression is a mathematical phrase written in numbers and or variables but do not contain an equal sign. The values of these terms in the expression are irrelevant.
ReplyDeleteAn equation can be solved because it contains and equal sign which ultimately means the amount represented on the left side of the equation is equivalent to the amount represented on the right side of the equation. An expression however cannot be solved, it can only be simplified because we do know what other expression or value it is equivalent to.
ReplyDeleteHmm can all equations be solved, I think No….though the concept behind an equation is that something must be equal to something, my theory is that given there are infinite ways an equation can be developed and arranged there may be just as many values for that given equation. Take for example what are known as indeterminate equations, this means that its solution may be vast in values, there is no one solution, there are millions and millions eg. 5x = y
ReplyDeleteSo no not all equations can be solved…then again it’s only my opinion…not a fact!
Real life scenario:
ReplyDeleteTravis loves fruits but he loves his girlfriend more. He decides to buy her 9 pieces of fruits to show her how much he cares. He has $17.25 to spend on the fruits. A peer cost $0. 75 and strawberries cost $1.25 each. Write down the equations involved and hence Calculate the number of each fruit bought.
what is a term? a term is just as important in an equation or expression as its connectors because without a term there cannot be an expression or equation, so in essence a term is the entity that goes before or after conncetors in an expression. In an equation however there is an equal sign so therefore a term must not only go before or after connectors but also an equal sign. Now a term can be any number albeit a -ve number or a +ve one, a term that is a number is called a constant. A term can also be a letter ranging from a-z. Variables and constants can also be combined.
ReplyDeletea machinist has to manufacture 59 shafts and gears if he has to produce 27 more shafts than
ReplyDeletegears how many of each did he produce.
the connectors in an equation are of course the signs: Addition:'+', Subtraction:'-', Muliplication:'x' and Division'/'. All of which generally increases or decreases the magnitude or size of a term
ReplyDelete59 shaft and gears
ReplyDeletehe has to produce 27 more shafts than gears
x shaft and y gears
x+y=59
27+y=x
-x+y=-27
-2x=-86
x=-86/-2=43
WHAT ARE CONNECTORS
ReplyDeleteconnectors are the symbols showing howthe elements in an expression or equation are related
an equation can be solved because the equation sign allows you to manipulate the known and unknown terms(transpose)of equal equations.the fact that equations have equal expressions and that the terms can be interchanged and transposed allows you to slove it.an expression ca'nt be solved because it does not have these properties ,unless youput an equal sign
ReplyDeleteThis comment has been removed by the author.
ReplyDeleteAn equation is a numerical statement that has variables and connectors.eg 4x+3=11
ReplyDeletean equation is a statement of equality.....
ReplyDeletea statement where two expressions are divided by an equal sigh and are of the same value.
A term can be defined as an expression(mathematical) associated with another by a + or - sign
How does the law of sines and cosines work??
ReplyDelete"d_blackman it has a trigs part for that.
ReplyDeletewell needed some more questions so i asked
ReplyDeletethe cosine rule works when the is two lines joined at a point and a angle is in between the.. while sine rule requires either 2 sides and an angle or 2 angles and a side...
ReplyDeletethe cosine rule is used when:1) you have an angle and the two lengths adjacent to it (used to find the length opposite to it) or 2) when u have the angle and one adjacent side and the opposite side(used to find the other adjacent side) or 3) when you have the two adjacent sides and the opposite side (used to find the angle between the two adjacent lengths)
ReplyDeletethe sine rule is used when you have 1) an angle and its opposite length and also another angle (used when you want to find the opposite length of that angle); 2)when you have an angle and its opposite length and also the opposite length of another angle (used when you want to find the value of that other angle)
ReplyDeletethanks guys
ReplyDeleteHi everyone just answering the term question ,please correct me if wrong thanks.
ReplyDeleteWell i think that it is anything which is seperated by an addition or subtraction .Also terms can either be a number or variable for example (a).
An example
4a - 3e = 3
I think it is important because it help to denote value .
Answering question on connectors please correct me if wrong.
ReplyDeleteI think connector are the signs or function in which terms are seperated by addition (+),subtraction(-),multiplication (*)and division (/)are connectors .
it is used for example 4*3=12
Answering expression
ReplyDeleteI think an expression is a mathematical phrase which contains terms and connectors and variable.example 15+5a but it can not be solved in order to produce an answer like an equation .
Just remembered that in some instance it can be siplified can be simplified using factorization in order to make it shorter and more compact.
ReplyDeleteExample of an expression and it simplified
6dx+12xc-2x
2x(3d+6c-1)
An equation is a statement with variables and connectors showing a relationship using an equal sign saying the input is equal to the output, i.e it can be solved.
ReplyDeleteVaribles are unknow numbers.
Connectors are used to connect two terms together eg. -,+,/

ReplyDeleteAn equation is a relationship which connects numbers and things together with an equal sign
ReplyDeletea term could represent a known or an unknown value.For eg known-5 an unknown-x
ReplyDeletethe connectors in an equation are the equals signs, + , - ,divide sign and *(multiplaction)
ReplyDeletean expression conects numbers and things together with +, - signs but doesn't have an end value so it doesn't have a equal sign.
ReplyDeleteAn equation is a mathematical statement that has two expressions which is equal.
ReplyDeletean equation is a a representation of the relationship between two or more values and always includes an equal sign (=) and an answer but not all the values may be known at that time including the answer. it can be as simple as x=2 or more complex with more variables like 2x - 4xy = 80
ReplyDeletea term is a known or unknown value in an equation like 2 (known) or x (unknown)
ReplyDeleteequation:
ReplyDeletex+y = 12
x-y = 56
x = (12 - y)-y = 56
12 - 2y = 56
2y = 56 -12
2y=44
y=44/2
y= 22
sub. y = 22 in eq.2
x - y = 56
x -22= 56
x = 56 + 22
x= 78
an equation is a relationship, which has two things. it shows how things are connected.(+,-,/,*)
an expression shows a connection but the end result is unknown so there is no equal sign.
connectors are (=,+,/,-)
a term is an expression
not all equations can be solved.
for example:
x+y = z
A term is a part of an expression separated by plusand minus signs. For example, the expression:
ReplyDelete4x³ + 7xy - 5y² -1
has four terms:
4x³
7xy
-5y²
-1
In mathematics, the word expression is a term for any well-formed combination of mathematical symbols.For example,
ReplyDeletex2 + 3x − 4
is an expression
Yes an equation can be solved because it has two expressions that is equal e.g.
ReplyDelete3x + 2y = 21
No an expression cannot be solved because it is only a +/- connection and there is no equal sign to work around e.g.
3x + 2y - 6x
Mrs.Monty bought 10 chickens and 4 ducks for $274.If,however,she had bought 4 chickens and 3 ducks the total cost would have been $160.Whats the cost of a chicken and the cost of a duck?
ReplyDeleteQuestion: Why is calculus neccessary?
ReplyDeletei think all equations can be solved
ReplyDeleteHI
ReplyDeletelet the price of one chicken = x
ReplyDeletelet the price of one duck = y
10x + 4y = 274...............(1)
4x + 3y = 160................(2)
from (2);
3y = 160 - 4x
y = 160/3 - 4x/3.............(3)
sub (3) into (1);
10x + 4(160/3 - 4x/3)= 274
10x + 4(160/3) - 4(4x/3) = 274
10x + 213.33 - 16x/3 = 274
4.67x + 213.33 = 274
4.67x = 274 - 213.33
4.67x = 60.67
x = 60.67 / 4.67
=> x = 12.99
sub 'x' into (2);
4(12.99) + 3y = 160
51.96 + 3y = 160
3y = 160 - 51.96
3y = 108.04
y = 108.04 / 3
y = 36.01
therefore the price of one chicken = $12.99
and the price of one duck = $36.01
REAL LIFE EQUATION
ReplyDeletei live in a village were everyone trades in apples.the only way apples can enter the viilage is through the central apple bank.they can then be loaned by other banks to viilagers who then compete with each other inorder to aquire enough apples to survive
now if X= the no. of apples loaned by the central apple bank and I A C S represents 4 groups of villagers in apple land ,while x represents one apple
EQUATION
Ix+Ax+Cx+Sx=X
NOW IN REALITY the central apple bank loans apples at interest ,thus
ReplyDeleteEQUATION
Ix+Ax+Cx+Sx< X,this means the amount of apples owed to the central apple bank is always more than the no. of apples in circulation.
an analogy is a game of musical chairs once the music stops ,either I A C or S is left out to dry ,meaning apple poverty cannot be eliminated because it is built into the system
ReplyDeleteA curve consists of the points through which a continuous point passes.
ReplyDeleteAn equation is simply a statement, usually made with numbers and symbols, that two things are equal.a term is 1 caracter in an equation. connectors are addition and subtraction. an expression is any meaningful combination of constants, operators, and variables representing numbers or quantities. all equations can be sloved because there is a reason for everything in maths.
ReplyDeletean equation is the relationship between numbers. they are connected by mathematical signs which relate to their function in the equation.
ReplyDeletean expression in short, shows a connection. It contains no value, and can vary accordingly.it is used to represent an unknown value or number.
ReplyDeleteconnectors in an equation are the mathematical signs used in the equation. Examples are the addition and subtraction signs.
ReplyDeleteother examples of connectors can be the multiplication and division signs.
ReplyDeleteA real life equation:mary bought 5 oranges and 3 pears for $15. While her boyfriend jake bought 2 oranges and 3 pears for $5."he cheap!"
ReplyDeletecal. the cost of one pear and one orange?
let the no. of oranges be x
let the no. of pears be y
EQUATION:
5x+3y= $15..............1
2x+3y= $5...............2
A term can be used to represent a certain, unknown value!
ReplyDeleteI think that equations can be solved, but the ans. may vary.Some ans. may be a number while others may result in an expression of the unknown!...............or so i think!
ReplyDeletean equation can be solved and an expression cannot be solved.an equation can be solved because it has an equal sign and an expression doesn't.
ReplyDeleteCan all equations be solved?
ReplyDeleteI believe that not all equations can be solved because there can be an equation like this
m+n=5p+8 and only the 'n' value is given.
ALL equations can be solved, this is so as there is a direct relationship between each term and its respective outcome-product.
ReplyDelete5x+3y= 15....(1)
ReplyDelete2x+3y= 5....(2)
from eqn(2)>> x= (5-3y)/2
x= (5/2)-(3y/2)....(3)
substitute eqn(3) into eqn (1)
>> 5 [(5/2)-(3y/2)] + 3y= 15
>> 12 1/2 - 7 1/2y + 3y= 15
>> -7 1/2y + 3y= 15 - 12 1/2
>> -4 1/2y= 2 1/2
>> y= (2 1/2) / (-4 1/2)
>> y= -5/9
substitute y= -5/9, into eqn (2)
>> 5x + 3(-5/9)= 15
>> 5x + (-1 2/3)= 15
>> 5x= 15 - (1 2/3)
>> 5x= 13 1/3
>> x= (13 1/3) / 5
>> x= 2 2/3
in terms of money, this equation had a problem. not in solving but for the fact that you cannot pay a negative amount of money for a pear.
in any case;
the price for an orange (X) is $2.66
and the price of a pear (Y) is -$0.55
a farmer has a seedbox with 12 tomato seedlings, each of 2cm in height.
ReplyDeletehe decides to do do a comparison of growth with fertiliser appliction.
splitting them in groups of 6 (group A and Group B), he applied 1GRAM to each in group A and 3GRAMS to each in group B.
the results of growth in a week, in cm,
were Xcm in A and Ycm in B.
write an equation to represent the height of the seedlings in group A and group B respectively and then solve.
the amount of growth with respect to fertiliser is given by [(3n)cm + 4cm]...

A term consist of whole numbers,and variables brought together by connectors(+,-). Together they form expressions and if an equal sign is added they can from equations.
ReplyDeletee.g of a term -> 3a² + 6b
e.g of not a term -> (3a + 6)²
Connectors in equations are(+,-,÷,×). I believe that these are symbols in maths or real life used to connect two or more terms together hence showing a relationship between them.
ReplyDeletereal life e.g.
god + pray + love - hate = happiness
I think an expression consist of values, variables and connectors but no equal sign i.e it does not have an output but still shows a relationship.
ReplyDeleteI believe an equation can be sloved and not an expression.Why? because an equation has an equal sign,so eventhough it has variables it can be slove,while an expression which does not have an equal sign and consist of variables, i believe it can just be simplifed.
ReplyDeleteYes all equations can be sloved, because the inputs are equal to the outputs.
ReplyDeleteQ:When is the sine and cosine rule used?
ReplyDeletesnowwhite... what i can recll off my head is the sine and cosine rule is used when a NON-Riht angle triangle is given. I may be wrong
ReplyDeleteKnowing that one quantity is numerically equal to another gives us one of the most powerful tools in mathematics, the equation. An equation is simply a statement, usually made with numbers and symbols, that two things are equal.
ReplyDeleteFor example, the simple equation 2 + 3 = 5 states that when the numbers on the left-hand side (i.e. 2 and 3) are combined using the addition operation, the result is equal to the number 5.
This may seem a roundabout way of stating the obvious , but the principle can be applied to less obvious situations - for example when the values of some of the terms in the equation are not known. We will use a simple equation to understand this better.
For a rectangular figure, Area = Length x Width.
Stated with single letters, the equation can be written A = L x W.
Applying this equation as written, you would be able to calculate A if you know L and W.
It is no surprise that if you know the area and the length, you would be able to calculate the width quite easily. For example if you know the total area of a rectangle is 35 m2, and that the length is 5 metres, what is the width?
What is an equation?
ReplyDeleteHmmmm.how to put this?...let's see...An equation is a statement which performs a function between two or more things and the output is known.
What is a term?
ReplyDeleteA term is an accessory in a statement on which a function is performed.
What are connectors in an equation?
ReplyDeleteThe connectors in an equation are the various functions that can be performed. Add (+),Subtract (-),Divide and Multiply (x).
What is an expression?
ReplyDeleteAn expression is a statement which performs a function between two or more things and the output is not known. an expression unlike an equation cannot be solved...only simplified.
Which can be solve and why an equation or an expression or both?
ReplyDeleteAn equation can be solved because the output is given and the statement can be manipulated to find unknowns.
Can all equations be solved? Explain.
ReplyDeleteNo.. because if there are two unknowns, the equation cannot be solved. Another equation of similar nature must be given in order to solve.
an equation is a relationship that shows how numbers and/or variables connect together to give a value
ReplyDeleteterm:
ReplyDeleteone of the numbers in a sequence or series. one part of an algebraic expression which may be a number, a variable or a product of both.e.g.
3a - b (terms are 3a and b)
term is used of a monomial with a coefficient: to 'collect like terms' in a polynomial is the basic operation of making it a linear combination of distinct monomials.
an equation shows a relation or connection between numbers or variables or both and has an equal sign.
ReplyDeleteconnectors of an equation include addition (+) subtraction (-) multiplication (x) and division (÷)
ReplyDeletean expression is a relationship between two or more numbers connected by the connectors listed above. (ex. 2+4) but an expression is not an equation because an expression does not have an equal sign to denote an answer to the expression (ex. 2+4=6)
ReplyDeletewhat is an equation? a equation is a statement that the values of two mathematical expressions are equal eg: (2 + 2 = 4) a equation is a statement using an equal sign. it is one way of showing a relation.
ReplyDeletewhat is a term? a term is each of the quantities in a ratio, series, or mathematical expression.
ReplyDeletewhat is a expression? a expression is a collection of numbers, symbols or letters with no equal sign expressing a quantity.
ReplyDeleteAn equation is a written statement that says one expression is mathematically equivalent to another.Equations will always have=signs in them.
ReplyDeleteA term is either a single number or variable,or the product of several numbers and/or variables separated from another term by a + or -sign in an overall expression. For example,in 3+4x+5yzw, 3,4x,and 5yzw are all terms.
ReplyDeleteConnectors in an equation include the following:addition,subtraction,multiplication,division.
ReplyDeleteAn expression is a term for any well-formed combination of mathematical symbols.
ReplyDeleteSamuel has x apples. Shanice has 2 times Samuel. Stephon has 3 times Shanices apples. How many apples does Stephon have if all the apples add up to 72 apples.
ReplyDeletex, 2x, 3x.
x + 2x + 3x = 72.
Thefore Stephon has (72/6)3 apples
all equations could be solved because it has a relationship and has a value as the answer.
ReplyDeletean equation is a mathematical statement where variables are used to solve a given problem or to be equal to a given number
ReplyDeletean equation is a mathematical statement of two expressions, usually divided by an equal sign, it shows that what is on one side of the equal sign is equal to what is on the other side of the equal sign.
ReplyDeleteconnectors in an equation are the function such as additon(+), subtraction(-),division(/) and multiplaction(*)
ReplyDeletean equation involves two mathemitmatical expression that are equal to each other
ReplyDeletean equation is a ststement that the values of two mathematical expressions are equal
ReplyDeletea term is each of the quantities in a ratio, series, or mathematical expression
ReplyDeletethe connectors in an equation i think would be the operation sign, whether it be addition (+) subtraction (-) multiplication (x) or division (/) they all help in connection
ReplyDeletean expression does not contain an equal sign, therefore it just states something that is not equal to anything
ReplyDeletean equation is an statement which compares either 2 or more unknowns with known values which is separate by two sides with an equal sign, which means that it could be solved or simplified .
ReplyDeletewhat is a term? a term is each of the quantities in a ratio, series, or mathematical expression.
ReplyDeleteAn equation is a mathematical statement that asserts the equality of two expressions.[1] Equations consist of the expressions that are to be equal on opposite sides of an equal sign, as in
ReplyDeletex + 3 = 5
9 - y = 7
Term - A part of an algebraic equation or a number in a sequence or a series or a product of real numbers and or variables.
ReplyDeleteExpressions - Symbols that represent numbers or operations. A way of writing something that uses numbers and symbols.
ReplyDeleteAn equation is a mathematical statement of equality.
ReplyDeleteImportance:
Think about a see-saw if the kids on each end both weigh the same what does the see-saw do?? it is balanced...isn't it???
so...one side of the see saw has to equal the other side of the see saw for it to be balanced.
now...think of an equation like a see saw. Whatever is on one side of it has to be balanced with the other side or it tilts. Well with an equation both sides must be balanced. If you add something to one side you had better do it to the other side or it wont be balanced.
a term is either a single number or variable, or the product of several numbers and/or variables separated from another term by a + or - sign in an overall expression. For example, in
ReplyDelete3 + 4x + 5yzw
3, 4x, and 5yzw are all terms.
the + and - signs are both connectors in this expression
equations are made of terms . therms are either the x's and y's or even any other value or constant and could even be the +/-* which are the signs.
ReplyDeleteequation has an equal sing which means that the terms on one side must equal the other side. while an expression is just a fact it has nothing to compare to the only this that could be done is to simplify an expression.
ReplyDeletean equation is a mathematical expression which suggests equality from this expression unknowns can be equated and solved for
ReplyDeletea term is an individual entity which has a magnitude it can be a known or unknown value
ReplyDeletea connector is a function which connects terms . in mathematics there are four basic connectors which are + - / x.
ReplyDeletejohn has 25 marbles, his brother peter has 3 times as many many marbles, together they have 100 marbles
ReplyDeleteequation therefore implies
25 + 3x25 = 100
A term is defined as an expression that is used to relate a particular value. It is a representation of something that has value.
ReplyDeleteall equations can be solved since it consist of a equal sign. the equal sign means that it can be solved even if i consist of variables by method of substitution or transposing .
ReplyDeleteexpressions cannot be solved since it does not consist of an equal sign.an equation on the other hand can be solved since it is a statement that compares 2 or more unknowns with known values which is separate by two sides with an equal sign.
ReplyDeleteAn equation is a arithmetic expression that equates one set of conditions to another.equations in mathematics is a statement usually written in symbols, that states the equality of two quantities or algebraic expressions.A numerical equation is one containing only numbers.An identical equation is a literal equation that is true for every value of the variable. Polynomial equations, contains more than one term.
ReplyDeleteA term means boundry line. it is either a single number a variable, or the product of several numbers.sometimes term is used with a coefficient.
ReplyDeletemathematical expressions include letters called variables. an expression represents a function.it is dependent on the definition of the mathematical operators .Two expressions are said to be equivalent if for each combination of values for the variables, they have the same output.
ReplyDeletea term is a fraction or proportion that is part of a series associated with another by a plus or minus sign
