# Prog modular arithmetics --- Introduction ---

This modules gathers interactive programming exercises, variable and configurable, on the subject of modular arithmetics. The software can ask you to produce an algorithm to compute addition, multiplication, power, polynomial, division etc. in $\frac{ℤ}{\mathrm{NZZ}}$, where $N$ is a prime. It will then compile your submitted code and test it on randomly generated integers for the validity of the code.
