Answer 1

3

Explanation:

No absolute value symbols!

|-6 - (-9)| = |3|

Once you have this down, you evaluate |3|, which is called an absolute value expression. Since it is already positive, you can just get rid of the lines.

If the answer was a negative number, you would make it positive and get rid of the lines.
