#124#

Explanation:

The absolute bars mean that the value must be non-negative. So if the argument between the bar is negative, the sign is "flipped" to make the outcome positive.

This also goes for less simple examples like #|x-1|#. Then the simplification would depend on the value of #x# being greater or smaller than #1#
