# Math: Sets & Set Theory

How to use Sets in Math?

We often deal with groups or collection of objects, such a set of books, a group of students,
a list of states in a country, a collection of baseball cards, etc.

**Sets** may be thought of as a mathematical way to represent
collections or groups of objects. The concept of sets is an essential foundation for various
other topics in mathematics.

This series of lessons cover the essential concepts of math set theory - the basic ways of
describing sets, use of set notation, finite sets, infinite sets, empty sets, subsets,
universal sets, complement of a set, basic set operations including intersection and union
of sets, using Venn diagrams and simple applications of sets.
