This brief article is intended to introduce the reader to the field of algebraic set theory, in which model of set theory of a new and fascinating kind are determined algebraically. The method is ...

Set theory is a mathematical abstract concerned with the grouping of sets of numbers that have commonality. For example, all even numbers make up a set, and all odd numbers comprise a set.

Example: X= (a, e, i, o, u) where, X is the set of vowels. We hope that these concepts along with their related exercise will aid you in your preparation of Set Theory topic.
