# Modular Arithmetic
## TLDR
When we divide two integers we will have an equation that looks like the following:
Sometimes, we are only interested in what the **remainder** is when we divide A by B.\
For these cases there is an operator called the modulo operator (abbreviated as mod).
Using the same A, B, Q, and R as above, we would have: **`A mod B = R.`**
