$p = 0$ $p = 0$

$| a | = a$ $abs(a) = a$ if $a \geq 0$ $a >= 0$

$| a | = - a$ $abs(a) = -a$ if $a \leq 0$ $a <= 0$

So if $| a | = b$ $abs(a) = b$ , then $b \geq 0$ $b >= 0$ and $a = \pm b$ $a = +-b$

In our example $| p | = 0$ $abs(p) = 0$ means $p = \pm 0 = 0$ $p = +-0 = 0$

How do you solve |p|=0absp= 0?
