Camren Nielsen · Answer 1

|x| meaning how much is from x to 0 so for example |4| = 4 and |-10| = 10 (it could never be a negative) but when the - is on the outside of the two lines then it turns to a negative like for example:

|23| = 23

But then ...

-|23|=-23

^because anything that is out of the two lines doesn't mean distance from that number to 0 only the ones inside
