3:20 fun fact: this is also know as the absorption law (A = A u (A n B) and A = A n (A u B)).

Thanks for making these videos... Set proof videos are very hard to find on youtube.

I am a high school student in India. Can you recommend any book on set proofs?

Sir, just a suggestion that the proofs of sets can be more clearly understood by Venn Diagrams ! Thank you for explaining this proof !

I think it would be helpful to include some LaTeX lessons as well.
