What is the Difference Between Membership & Subset?

In this video, I cover examples of memberships and subsets. This problem can be found in the free open-access textbook: "Applied Discrete Structures", authored by Dr. Ken Levasseur and Dr. Al Doerr https://faculty.uml.edu/klevasseur/ads2/ Any feedback on how these videos can be improved would be great. I will be constantly updating these videos to ensure that everything is accurate. Thank you all for being such a great community.

My name is Kody Amour, and I teach free undergraduate mathematics courses on YouTube. I'm currently developing three YouTube courses simultaneously: Discrete Math, Linear Algebra, Real Analysis, Topology, Number Theory and Complex Analysis. These courses correspond to playlists that I am constructing indefinitely. You have already given me a view and your watch time, which means a lot to me already.
