Alrighty folks, I have a simple question for the fans of critical thinking and/or you (fellow) math heads: In your own words what do you think is the difference between a mathematical expression and an equation. Secondly under what conditions would they be the same. No cheating. Really think about it, feel free to use analogies. Work for those Yahoo points!

2+x expression
2+x=4
2(2+x)=8 equations
Think like a see-saw, and the = is the balancing point. The two sides must come out to the same quantity. An expression is only one side, or part of one side, of the see-saw; an equation is showing both sides of the see-saw in balance.

what's the version between an equation and an expression? incorporate an occasion of each. the version between an equation and an expression may well be whilst in comparison with the version between a word and a sentence in grammar. An expression (i.e. 4x, 10 + 2, and so on.) could desire to be whilst in comparison with a concern or an merchandise. by using themselves, they recommend little or no. once you upload a verb (=), you get an entire sentence (i.e. 4x = 10 + 2). are you able to remedy for a variable in an expression? clarify. No, no longer in a expression. x represents the variable in the expression 4x. There are an endless variety of opportunities you could replace for the x, so it won't be able to be solved. are you able to remedy for a variable in an equation? clarify. confident. because of the fact we've an entire sentence we could make experience of the equation 4x = 10 + 2. because of the fact all of us comprehend that 10 + 2 may well be written as 12 and recommend a similar subject, we can substitue the main appropriate variety for the x so the expressions on the two aspects of the = sign characterize a similar fee. 4 * 3 = 10 + 2. Write a mathematical word or sentence to your classmates to translate. you have been assigned to deliver 4800 gizmos to a job internet site. what proportion packing containers could could desire to be loaded on each and each truck in case you could desire to %. 8 products in each and each field and additionally you had 3 automobiles available.

A mathematical expression can be identified as the equation or the answer.
The equation itself is comprised of mathematical expressions that are listed in a particular way so that the answer (again, also an expression ) can be derived.
Not even sure if this is close. I will be curious to see that others have to say....

an expression is a mathematical sentence of terms w/o an equal sign(=).
Example: 2x-3p
5y+17x
an equation is a mathematical sentence w/ an equal sign(=).
Example: 5+7=12
145-11=134

The answer is an equal sign. An equation has one, an expression does not. They are never the same.

I think that an equation is with all numbers. And the expression has a variable (which means unknown number)
They both deal with numbers and you have to solve both of them

simple, simple

that is, equations include the = sign but the expressions do not
