I am a 68 year old former accounting professor. Your elementary set theory video should be required viewing for accounting students, and I believe it would have value for students in just about any subject. By focusing on general purpose reasoning skills the video transcends subject matter boundaries. By spending a couple of hours with your video today and referring back to it as the need arises, students could avoid countless hours, days, and weeks of pointless flailing around in the future. Specific content comes and goes but logic is here to stay. Your video proves the old adage that there's nothing more practical than a good theory.

This video is extremally underrated. I'm surprised that this has only 15k views for such quality.

I love ❤ set theory . I have old (1980s) Year 8, and Year 9, maths books and I studied the set theory chapters in great detail. I took very comprehensive notes. For some reason I find it very interesting. It helped a lot with probability and statistics. I like the older mathematics textbooks. Your information and teaching methods are great. 🥳

Thank you so much. You've just made my first three weeks of my Masters make sense in 10 minutes

N_0 and N_1 are used to distinguish between a set of natural numbers beginning with zero or one. This notation removes the ambiguity. (Since I can't paste in the actual figures, a_b means a-subscript-b. Also, assume the N is the one Dennis shows with double lines.)

@Dennis Davis Sir I have a question: If the empty is a subset of every set, the how is U complement equal to the empty set. ( Since the empty set is a part of U and not outside it)?
