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.

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.

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.!!!!

[@user-wy7wl5on7l]

This was exceptional. I am self studying real analysis rn and I honestly cannot see what the need for over complications when explaining simple concepts like this

[@quietpessimistic]

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.

[@willbelasco]

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]

mettaworldwill That will give you an empty set or a null set.

[@youngboydan4153]

It is technically part of Algebra I curriculum. So, it depends on when you take Algebra I. Most students take Algebra between 7th and 9th grade, depending on their level of mathematical ability.

There might be something I'm not understanding but "3" is NOT in x OR y. It is in BOTH therefore it is not in one OR the other. Even in the illustration only the things that DON'T overlap are shaded. (5:21-5:30)
