Question

Explain Cartesian product.

Answer 1

The set of all ordered pairs a and b, where a is an element of A and b is an element of B, is called the Cartesian product of A and B and is denoted by $A\times B$
For Example:
Let A = {1, 2, 3} and B = {a, b}. Then
$A\times B=\left\{\right(1,a),(1,b),(2,a),(2,b),(3,a),(3,b\left)\right\}$
