[SOLVED] group theory question 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.
