If the universal set, U, has N elements then it has 2N subsets.

For example, if you take the set A = {1, 2}, then the following sets are all subsets of it: {}, {1}, {2}, {1, 2}. That is, all the sets that fulfill the condition that all of its elements are also elements of the set "A".

If tiu have a set S, its power set is the set of all subsets of S (including the null set and itself).

Once example is the whole numbers and subsets are the numbers 1,2 and 3 written {1,2,3}. Another example is all the colors. Subsets would be any number of individual colors. The universal set may be finite or infinite.

If set A is a subset of set B, that means that all elements in set A are also in set B. In the case of a proper subset, there is the additional specification that the two sets are not equal, i.e., there must be an element in set B that is not also an element of set A.

It is the set of all the things you are dealing with or considering. For example, if I am looking at subsets that are even integers and I am looking at all integers, then the set of all integers is the universal set. If we are looking at hair color, some subsets are redheads, blondes etc. The universal sets is the set of all possible hair colors.

The universal set is represented by a rectangle. Subsets of this set are represented by closed curves (often circles).

A ∩ B The union of two sets (A & B) is the set of all elements contained in A & B. A ∪ B.
