When is Modulus Negative !

The Recruit wrote:Hello Everyone,

This is very basic, but i still wanted to get it cleared.

Q: When is modulus of a number negative, i know that only when x<0 ,

so that means |-3|=3 ? cant be right

so, someone please explain that what are the cases in which |x|=-x [ yes, only if x<0 but how ]

Thanks a tonne for replying , kind souls !

• 1. |x| = x for x ≥ 0
  2. |x| = -x for x < 0

so if u'stand correct, Based on |x| = -x for x < 0

|-3| = - 3 as -3<0, but thats not correct !

Thanks for clearing
