Operator - Simple English Wikipedia, the free encyclopedia

In mathematics, an operator is a function (like addition) that acts on one or more numbers to create a new number.

The most known operators are those used for the first four arithmetic operations: addition, subtraction, multiplication, and division (${\displaystyle +}$, ${\displaystyle -}$, ${\displaystyle \times }$, ${\displaystyle /}$).
