Operations on Sets
The main ways two or more sets can be combined or compared.
Union and Intersection
The union $A \cup B$ contains all elements in $A$ or $B$ (or both). The intersection $A \cap B$ contains only elements common to both.
Difference and Complement
The difference $A - B$ contains elements in $A$ but not in $B$. The complement $A'$ contains all elements of the universal set not in $A$.
