Vectors and magnitude

  1. Sep 18, 2006 #1
    hello, can someone please tell me if this is correct? no it is not for my homework.

    place vector symbols above all letters.

    |m-n| = |n|-|m|

    place vector symbols about the letters to specify they are vectors

    so are they the same?

    If I understand the question, then no they are not the same. Can you tell me why?

    For example, look at m=n and m=-n.
