Question

How do you combine like terms in `18n - 11n - 17`?

Answer 1

Like terms are like counting how many similar things you have.

Explanation:

For example, if you have `18` apples and `17` oranges and I take away `11` apples you only have `7` apples left and still `17` oranges.

So if you have a `18n` and a `-17` and `11n` are taken away you have `7n` left and still a `-17`.

This means that `18n - 11n -17 = 7n - 17`.
