In this lesson, Julie Harland teaches about the intersection, union, complement, and difference of sets using examples. She starts by defining intersection as the common elements between two sets and union as the combination of elements from two sets without repetition. She then moves on to complement, which is all the elements in the universe that are not in the set, and difference, which is the elements of one set that are not in the other set. She emphasizes that order matters with difference but not with intersection and union. This lesson provides a solid foundation for understanding set theory.
