8. UNION OF SETS A union of set A and B is the set of elements that are in A, in B, or in both sets. Usually, we write the union of set A and B as A U B.

9. COMPLEMENT OF SETS The complement of a Set A is the set of all the elements in the universal set that are not in Set A. We write the symbol of complement of Set A as A’ .

10. DIFFERENCE OF SETS The difference of a set A and B, written as A-B is the set of all elements of A that are not elements of set B.
