**or** takes two numbers or expressions, and checks to see if *either one* is True. If both are False, it returns 0. If at least one is True, it returns 1. **or** is commutative (i.e. the order of arguments does not matter). As with **And**, you can use variables and expressions, and use multiple **or'**s together.
