# Ring Calculator

This calculator finds the units and zero divisors of a given modulo ring of the integers. Enter a value of $n$ for the ring you require. For example $\mathbb{Z}_6$ is the ring:

\begin{align*} \mathbb{Z} \mod 6 &= \{ 0, 1, 2, 3, 4, 5 \;|\; 6 = 0 \}\\ &= \{ 0, 1, 2, 3, -2, -1 \;|\; 6 = 0 \} \end{align*}
