What makes them equal? Turns out if they have the exact same elements, two sets can be considered equal. It is much more convenient to compare sets in their roster forms than set-builder forms. Let's have a closer look at equal sets through some examples.

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.
