Binary function

In mathematics, a binary function (also called bivariate function, or function of two variables) is a function that takes two inputs.

Precisely stated, a function $f$ is binary if there exists sets $X,Y,Z$ such that

• ✤ $f:X\times Y\to Z$

where $X\times Y$ is the Cartesian product of $X$ and $Y.$
