1. The problem statement, all variables and given/known data

A student is asked to show that if H is a normal subgroup of an abelian group G, then G/H is abelian. THe student's proof starts as follows:

"We must show that G/H is abelian. Let a and b be two elements of G/H."

Why does the instructor reading this proof expect to find nonsense from here on in the student's paper?

2. Relevant equations

3. The attempt at a solution

That's probably how I would start my proof...I don't see anything wrong with it.
