## Venn Diagram Definition:

A picture of sets.
Sets = circles
Rectangle = Universal set

## Set Definition:

Recall our lesson on sets
A collection of things.
Examples include letters, numbers, fruits.

## Set Intersection.

Intersection of A and B is A ∩ B
A ∩ B means everthing in both A and B:

## Set Union

Union of A and B is A U B
A U B means everything in A or B

## Complement of a set:

AC or A' means everything in U not in A.

##### How does the Venn Diagram Calculator work?
Free Venn Diagram Calculator - This lesson walks you through what a Venn diagram is, the Venn diagram for A union B, A intersection B, and A Complement.

### What 3 formulas are used for the Venn Diagram Calculator?

AC = U - A
A U B = A + B
A ∩ B = A + B - A U B
