Cartesian product

From Simple English Wikipedia, the free encyclopedia

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,[1] 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.[2]

For example, let A = {1, 2, 3} and B = {a, b}. Then:

The set of a Cartesian product can be visualized as a two-dimensional table, with its entry being its elements.[3]
