## Visualizing Absolute Values on a Number Line

On a number line, the absolute value of a number is given by its distance from zero. For example, it can be seen that 3 is 3 away from zero, and so has an absolute value of 3. It can also be seen that -2 is 2 away from 0, and so has an absolute value of 2:

## The Absolute Value of Zero

The absolute value of 0 is 0. 0 is neither a positive nor negative number. As the absolute value of any other number is always positive, the absolute value of any number must be greater or equal to 0.
