Going Round in Circles
Is it fun to go round in circles?
OBJECTIVE: To use Venn Diagrams to perform set operations
In previous lessons, you learned about the definition and classification of sets and subsets, methods of naming sets, cardinality and comparison of sets, and operations on sets.

In this lesson, you're going to learn how to use Venn Diagrams to perform set operations.
Venn Diagrams, also called Set Diagrams or Logic Diagrams, use overlapping circles to illustrate the logical relationships between two or more sets. They serve to graphically organize things, highlighting how the elements are similar and different. They are used to think through and depict how elements relate to one another within a particular “universe.” Venn diagrams show relationships even if a set is empty.
The applet below shows a Venn Diagram for three sets. Click on the buttons or bars to see a visual representation of the indicated set operations.

In this lesson, you learned how to use the Venn Diagram to perform set operations.
In future lessons, you'll learn about the Set of Real Numbers and its subsets. Hope you had FUN in this lesson!
