## Why Z is not a group?

The reason why (Z, *) is not a group is that most of the elements do not have inverses. Furthermore, addition is commutative, so (Z, +) is an abelian group. The order of (Z, +) is infinite. The next set is the set of remainders modulo a positive integer n (Zn), i.e. {0, 1, 2, …, n-1}.

## Is infinity a real number?
