4.22 Equality of Two Sets

Two sets A and B are equal if and only if every element is A belongs to B and every element in B belongs A.

Example:
A = {John, Peter, Sue}.
B = {Sue, Peter, John}.
The persons that are in sets A and B are same. The persons that are in A are in B. Thus the sets A and B are equal sets.
