Question

How do you simplify `abs(-13)`?

Answer 1

Remove everything from `|-13|` except for the number 13

Explanation:

`|-13|=13`

Just remove the absolute value and negative symbols

`color(red)|-|`

and keep `13` to simplify `|-13|`

basically, remove everything that is not a number from the question

If any number = `x`

simplifying `|-x|` means remove `abs` and `-` from `x`

the simplified version of `|-x|` which is just `x`
