Discrete Mathematics Set Theory Notes

Set Theory


A set should be a well specified collection of objects. “it must be possible for  us to decide whether the object belongs to the collection ( under consideration) or not.

We  use capital letter to represent sets and lowercase letters to represent elements. For set A we write  if x is an elements of A :  indicates that y is not a member of A.

A set can be designated by listing its elements within set braces ( tabulation methods).
