 Absolute Value:  The absolute value of a number is the distance the number is from zero on the number line.


We write the absolute value of -2 as | -2 |.

The absolute value of a number is found by determining how many units the number is from zero. Since distance is always thought of as positive, the absolute value of any number is positive. For example, -2 is 2 units from zero, so | -2 | = 2. In the picture below, you can see that | 4 | = 4 and | -4 | = 4, because both 4 and -4 are 4 units from zero on the number line.
