Question

How do you combine like terms in `m-8m+8m+2`?

Answer 1

The answer is `m+2`

Explanation:

You are basically combining like terms. Think of `m` as apples.

You have `-8` apples `+ 8` apples, therefore that would equal `0`.

You have still one apple left and `2`, so

`m+2`

You can only add and subtract like things, e.i you can't add `2` apples to `5` oranges and say you have `7` oranges, that's impossible.

This is the same concept.
