Set Theoretic Operations
Concept: Complement
The complement of a set A is a new set, denoted as A', containing all the elements of the universal set U which are not members of the set A.
Graphic Representation
The area shaded in orange represents A'.
Example
If U = {1,2,3,4,5,6,7,8,9} and A = {1,2,3,4},
then A' = {5,6,7,8,9}.
