Union of Sets

The question:

What is A U B ABOUT IN MATH ?



The answer:

U stands for the union of the two sets. In this case A U B means the union of set A and set B.

Union means combine all the elements of one set with all the elements of another set.

For example, suppose set A is composed of the following numbers {1,2,3}, and set B is composed of its own group of numbers {9,11}.

A U B means that both sets of numbers are combined {1,2,3,9,11}
