A strict subset is a subset that isn't equal to the original set (i.e. B must have at least one fewer element than A). A superset of A is any set C such that A is a subset of C.

After plotting all of them on a Venn Diagram, lets create a subset chain that goes from natural numbers all the way to real numbers.

We also look at a few practice problems where we apply the knowledge of inequalities to describe different types of intervals.
