I'll post the problem and my attempt at solution all in one picture:(adsbygoogle = window.adsbygoogle || []).push({});

In the red step, I'm using commutative multiplication. Am I allowed to do this? I'm not sure, because the subset of G might not be a subgroup, so I don't know if its necessarily abelian like G is. Or does the fact that G is abelian override this somehow?
