Question

what is the absolute value of -2?
2 1 -2 0

Explanation:

Step1: Recall absolute value definition

The absolute value of a number $x$, denoted $|x|$, is its distance from 0 on the number line, so $|x| = x$ if $x\geq0$, and $|x| = -x$ if $x<0$.

Step2: Apply definition to -2

Since $-2 < 0$, $|-2| = -(-2) = 2$.
