5 units from 0 5 units from 0

Both 5 and 5 are 5 units from 0. |5| |5|  5

The absolute value of positive 5 is 5. Write: | 5|  5

The absolute value of negative 5 is 5. Write: |5|  5

The absolute value of 0 is 0. Write: | 0 |  0

Key Concept

Absolute Value

Since distance cannot be

negative, the absolute value

of any number is always

positive or 0.
