Let $n \in \Z_{>0}$.
The additive group $\left({n \Z, +}\right)$ of integer multiples of $n$ is the set of integer multiples of $n$ under the operation of addition.

Thus integer addition is:
- Well-defined on $n \Z$
- Closed on $n \Z$
- Associative on $n \Z$
- Commutative on $n \Z$
- The identity of $\left({n \Z, +}\right)$ is $0$
- Each element of $\left({n \Z, +}\right)$ has an inverse.
