Among the most basic topics taught in elementary school mathematics are operations such as addition and multiplication of numbers. Each such operation takes two numbers, and produces a single resulting number. Another type of operation is negation of numbers, which takes a single number and produces another number. We can formalize both these types of operations using sets and functions.
