Introduction to Sets | Discrete Mathematics

How to specify Sets?
Set is a collection of elements. For instance, If S is the set of all integers from 1-1000, then the number 500 is an element of the set S. A set is specified by writing elements in braces. For example, {apples, oranges, mango's} is the set whose elements are apples, oranges, mango's. If A is a set, the notation x ∈ A means that x is an element of the set A. The notation x ∉ A means that x is not an element of the set A.
