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.
