Decide whether the given set of numbers is a commutative group under the given operation. Whole numbers; addition 
 A. No  
 
 B. Yes

anonymous · Answer

It's asking if you have only whole numbers and it's using only addition can you use the commutative properties of addition (can you change the order around?).

anonymous · Answer

Yes, that is an axiom of the whole numbers.

anonymous · Answer

In fact, the integers; but since the whole numbers are a subset of the integers, and we are not concerned about additive inverses or identities, it holds for the whole numbers as well. I must emphasize that this is an axiom, and that you do not "decide" if it is true.

anonymous · Answer

Well, the decision is whether or not this is a condition within that axiom.

I just told you that it was.

Bahaha, I was interpreting your replies as if you were the original inquirer.  So, when you were confirming what I was saying I was confused as to why you were doing so.
