Set Theory
Set theory deals with grouping objects together and viewing them as a single entity.
A set is a collection of things, such as of numbers (e.g.: 3, 4, 5), letters (e.g.: a, b, c, d), or objects such as utensils (e.g.: spoon, fork, knife). Set theory is that field of mathematics which deal with properties of sets, independent of the things which make up the sets.
A set is defined by properties which objects should possess – all those objects which meet the criteria form the set. Thus, considering all numbers, if the criteria is for the number to be prime, then all primes (2, 3, 5, 7, …) form the set.
Sets may be combined by certain operations to form other sets. Set theory is fundamental to the study of many areas of mathematics.
