The absolute value of number -13 is 13. The opposite of number -13 is 13.

Work Step by Step

Since the absolute value of a number $A$ is that number's distance from 0 on the number line, if $A=-13$, then $|-13|=13$. Since the opposite of a number $A$ is to put a negative sign in front of the number, if $A=-13, -A=-(-13)=13$.
