The cardinal number of a set A indicates the number of elements in the set A.

The cardinal number of a set A indicates the number of elements in the set A. n(A) is the cardinal number of set A.

The universal set U is defined as the set that consists of all elements under consideration. We usually denote the universal set with a capital U.

The compliment of a set A is the set of all elements that are in the universal set U, but not in A. The compliment of a set A is denoted as
