A and B are two non-empty sets, then their Cartesian product A × B is the set of all ordered pair of elements from A and B.
A × B = {(x, y) : x ∈ A, y ∈ B}
Suppose, if A and B are two non-empty sets, then the Cartesian product of two sets, A and set B is the set of all ordered pairs (a, b) such that a ∈A and b∈B which is denoted as A × B.
For Example;
1. If A = {7, 8} and B = {2, 4, 6}, find A × B.
Solution:
A × B = {(7, 2); (7, 4); (7, 6); (8, 2); (8, 4); (8, 6)}
The 6 ordered pairs thus formed can represent the position of points in a plane, if a and B are subsets of a set of real numbers.
