I have a midterm tomorrow morning and I am completely lost on how to finish the problem, I was told a question tomorrow will mirror this one so any help is appreciated.(adsbygoogle = window.adsbygoogle || []).push({});

Question:

Prove any group of order 9 is abelian.

Answer:

Let G be a group such that |G|=9

One of these elements has to be the identity.

The remaining 8 will consist of 4 elements and their respective inverses.

Where do I go from here?
