Combining Like Terms
Apples and oranges
This is one of those algebra skills that looks challenging but it actually extremely simple. If you can sort and count, you can add and subtract algebraic expressions, otherwise known as combining like terms.
Since the very beginning of math, we've only ever been able to add the same kinds of things. Ones with ones, tens with tens, halves with halves, and apples with apples. Adding and subtracting in the world of algebra is no different. Turns out that you can only combine like terms- terms that have the same variable portion: x's with x's and y's with y's.
