Category:Examples of Use of Integer Multiples form Commutative Ring

This category contains examples of use of Integer Multiples form Commutative Ring.

Let $n \Z$ be the set of integer multiples of $n$.

Then $\struct {n \Z, +, \times}$ is a commutative ring.

Unless $n = 1$, $\struct {n \Z, +, \times}$ is not a ring with unity.
