Answer
-8
Work Step by Step
The absolute value of x, written by the form $|x|$, is the distance between x and 0 on the number line. It is equal to:
x if $x\geq0$
-x if $x\lt0 $
Since $-8\lt0$, $|-8|=8$
Since an additional negative sign is outside of the absolute value sign, this problem asks us to find the opposite of the absolute value of -8.
$|-8|=8, so -|-8|=-8$
