Homework Help: Commutator relations

  1. Apr 29, 2014 #1
    This is not a homework question, I just can't find a good resource on this topic.

    I am working in quantum mechanics on commutator relations. My book (Griffiths) lacks information on how to manipulate the commutator relations.

    For instance, when I have [AB,C], when can I make it A[B,C]? Or is it A[B,C]+[B,C]A? I can't find an online resource that explains these things. Help please!

    Do things like the product rule in differentiation:

    [AB,C] = [A,C]B + A[B,C]
