A set is a collection of clearly specified unique items. The term "well-defined" refers to a property that makes it simple to determine whether or not an object belongs to a set. The word 'distinct' implies that all of the objects in a set must be unique.

As an example:

A set is defined as a group of children in grade 10 who weigh more than 35 kg. Because the term "intelligent" is ambiguous, the collection of all intelligent children in class 10 does not constitute a set. What one individual considers intellectual, another may not.

In this “Introduction To Sets - Mathematics I” you will learn about the following topics:

1. Introduction to sets
2. Types of sets
3. Venn diagram
4. The number of elements in a set
