Venn Diagrams

Venn diagrams show sets as circles. Overlapping regions represent intersection. Non-overlapping regions represent differences.

For example, if you draw two circles for sets $A$ and $B$, the overlap shows $A \cap B$. The part of $A$ outside $B$ shows $A \setminus B$.

Venn diagrams help you see relationships between sets. They make union, intersection, and difference intuitive.
