# Cartesian Product

## Objectives

To find cartesian product.
To find the relation between n(A×B), n(A) and n(B).

## Introduction

**Cartesian Product**: If A and B are two non-empty sets, then the set of all possible order pairs where first elements are from set A and second elements are from set B is called Cartesian product of A and B, denoted by A ×B. If first elements of order pair are from B and second from A, then the Cartesian product is denoted by B×A. i.e. A×B={(x,y): x
