If x is negative, | x | = − x
If x is negative, | x | = − x
I see what you're saying...I think the working just needs to be changed. |-x| = x but if you declare before hand that x is negative to begin with then |x| is negative, but if you say it equals x, x is still assumed negative. Let's just reword the whole thing, shall we? --[[User:DavidB4|David B]] ([[User talk:DavidB4|talk]]) 20:48, 14 April 2016 (EDT)

:How about simply:
:<math>|x| = x</math>
:<math>|-x| = x</math>
or even show all the signs:
:<math>|+x| = +x</math>
:<math>|-x| = +x</math>
What do you think?--[[User:DavidB4|David B]] ([[User talk:DavidB4|talk]]) 20:51, 14 April 2016 (EDT)
