# Cartesian product facts for kids

In mathematics, sets can be used to make new sets. Given two sets *A* and *B*, the **Cartesian product** of *A* with *B* is written as *A × B*, and is the set of all ordered pairs whose first element is a member of *A*, and whose second element is a member of *B*.
