Well, the phrase they often use is about "apples and Oranges"... If you add them together, you tend to get senseless answers. For example: to add 3 km + 300 meters, it is clear that, since 3 km = 3000 meters, the answers is 3300 meters. If you just go ahead and add 3 + 300, for an answer of 303, well, that doesn't make any sense whatsoever.

How do you combine unlike terms?
Unlike terms are terms in an equation that are different. These terms cannot be combined. Like terms, however, can be combined.
How do you add like terms?
To add like terms, find the terms that have the same (or no) variable, and combine the coefficients of the terms. For instance, if you have a+b where a and b are real numbers, you can combine them.
Can you multiply unlike terms?
Yes, you can. For example 3x times 4y = 12xy.You cannot however, add like terms (to combine them, that is. There isn't anything wrong with adding them up, 3x + 4y is acceptable). For example, 3x + 4y is as simplified as it can get.
Combine like terms?
mathematics: to combine terms that are alike
What are unlike terms?
one that won't talk to one another because they don't like each other... NO, seriously, they are terms that are different. For example x^2+2x+3x-4x^2. The x^2 terms are like terms and the x^2 terms and the x terms and unlike because they are different. Just like x and y, or apples and oranges.
How do you combine unlike terms?
Unlike terms are terms in an equation that are different. These terms cannot be combined. Like terms, however, can be combined.
Can you subtract unlike terms?
No. You can't subtract unlike terms
If terms are not like terms then they are?
Unlike terms.
How do you simplify 21t plus 14-12t-30?
You can combine like terms - combine the terms that have a "t" in them; separately, combine the terms that don't.
Does an expression have an answer?
A mathematical expression does not have an answer, if it is algebraic and all of the terms are unlike. For example, x+7y does not have an answer because there are no definite solutions, and there is no possibility to combine like terms. However, the expression 2x+7y+3x does have an answer, but the solution is merely the combination of like terms. (5x+7y)

Do combiming like terms mean the same as combine the expression?
no, combining like terms means combine the terms that are the same 15+x+6+x=28 combine like terms 21+2x=28 2x=7 x=3.5
