Question

How do you solve `abs(x)<15`?

Answer 1

`-15 < x < 15`

Explanation:

The absolute value means that the number is always positive so, for example

`|-3|=3`

So if `|x|` needs to be smaller than `15`, you can't go lower than `-15` because that would be

`|-15| = 15`

just as `|-16|` wouldn't be smaller than `15`, since it's the same as `16`. You can't go higher than `15` either because

`|15| = 15`
