KHAAAAAAAAAAAAAAAAAAAAAAN! THIS IS EFFING AWESOME! I can't believe Khan is teaching us about Set Theory. I think he's finally starting more advanced Math. I feel like I am in a dream. I already know most of this stuff but nothing equals Khan's level of delivering a message so I'll watch them all at least three times each. Thank you, Sal.

THANK YOU!!!!!!!! you are a better teacher than the dinosaur that I have for a teacher

[@denadagjyzeli1983]

My former math teachers ruined math for me. I went from straight A to C due to the fact that they were horrible either in math or in explaining iy

[@evan.5967]

That’s a bit rude

[@itsev6970]

These tutors do not have misbehaving students to contend with when they are explaining... Hence it will always be easier than being in a class with disruptive students.!!!!

[@robman8855]

I must compliment you on how well you taught this subject.

This is really great Sal! Thank you very much. I sincerely hope you will do more videos on discrete mathematics. If you have some spare time I would like to see a video on the barber paradox, should be a fun brain teaser for all ages.

5:24 Shouldn't you also cover the intersection since you write X union Y = {3,12,5,13,14,15,6} but you don't cover 3 in the drawing.

what if you need to define the intersect and both sets don't share any of the same numbers? how is that defined / expressed?

[@rohaanashraf8589]
