Hi,
Firstly I am not sure what a group is, after being given the 4 group axioms.
I'm not sure what relevance ''closure'' has ?
and my question is : how to show that for every natural number,n, the set Zn of integers modulo n forms a group under addition modulo n ?
I appreciate any guidance.
Thankyou very much.
Roger
