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

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