The absolute value of -9 is

=|-9| = 9

Explanation :

Here's how you can picture absolute value: Think of a railroad track with a zero sitting in the middle of it. Every little notch to the left and right of the zero is another number. Negative numbers line up on the left; positive numbers run along the track to the right. So, the number -4.0 is 4 units away from zero. The number -45.3 is 45.3 units away from zero and the number 10 is 10 units away from zero. Therefore, the absolute value of any number is really a positive number (or zero). You identify an absolute value of a number by writing the number between two vertical bars: |number|.
