Hello, MT,
Wish I could be of help with this question, but have not studied abelian groups.  
Have you tried doing an Internet search for this topic?  Bet you could uncover some good explanations pretty quickly that way.  Good luck!!

Sorry, I haven't studied abelian groups either, you are probably expecting that I am typing the world most helpful staff, but no I am not; sorry, but unfortunately I can't help you with this.
