Question

How do you simplify `abs( -31+15)`?

Answer 1

`16`

Explanation:

`1`. Within the bars of the equation, do the addition of `-31` and `15`.

`|-31+15|`

`=|-16|`

`2`. The bars indicate that the result is always positive. Thus, remove the negative sign as well as the bars.

`=color(green)(|bar(ul(color(white)(a/a)16color(white)(a/a)|)))`
