Just remember how Billy wanted the entire Mysteries of Michael series next time you're having trouble with sets! A good way to think about it is: we can't find any elements in the empty set that aren't in A, so it must be that all elements in the empty set are in A. The intersection is empty and represents the fact that Cynthia and Damon have no common courses. And 3, And 4. Well, simply put, it's a collection. But {1, 6} is not a subset, since it has an element (6) which is not in the parent set.

First we specify a common property among "things" (we define this word later) and then we gather up all the "things" that have this common property.
