Question

$$- | 21 | + | 21 |$$

Evaluate

$0$

Solution Steps

The absolute value of a real number $a$ is $a$ when $a\geq 0$, or $-a$ when $a<0$. The absolute value of $21$ is $21$.

$$-21+|21|$$

The absolute value of a real number $a$ is $a$ when $a\geq 0$, or $-a$ when $a<0$. The absolute value of $21$ is $21$.

$$-21+21$$

Add $-21$ and $21$ to get $0$.

$$0$$

Factor

$0$
