there has never been a topic in math, physics, chemistry or biology that i've had to learn that the great Khan hasn't helped me with, ever, and i'm not even from the states (different topics in respective subjects)
Is this going to be a play list of set theory videos? If so I REALLY hope you cover the Paeno axioms and Cantor's diagnoalisation proof of the different types of infinity. That really deepened my understanding of what mathematics was about and deserves to be more widely know as it isn't that hard.
This is so simple for us only because we have been so close to it physically and have had so many minds & pens make it simple for us . The Universe is really , ultimately no different ~ except physical concepts are meanigless when we try to comprehend , that ocean or root system ~ God is a Spirit : )
I have a ❓ I have A=(1, 2, 8) B=(2, 4, 6) C= (1, 2) As far as I can understand, "A is the superset of C" right? If someone can answer please (thank you)
Tangent Hypothesis , if we applied our total comprehension of our physical Earth , the Trees , soil structure , different 'layers , etc . and were able to see a complete view of the entire planets "invisible world " or typically hidden world , the rocks & dirt , oceans and grains of salt within them , etc
I have kind of a weird question. How was this recorded? I work for a university, and we're trying to figure out a way to record a prof working through a problem, exactly like what this instructor is doing. We've tried touch-panel monitors; however, they're very awkward and don't work well. Any ideas would really be appreciated.
If A = 1 2 3 5 and B = 1 1 2 3 would B be a subset of A? (I apologize for omitting the mathematical notation, UA-cam says that I cannot post "ascii art".
will a set still be a subset to another set if there is one extra element not in the other set. for example A= (1,2,3) B = ( 1,2,4 ). So will B still be a subset of A even though there is an element that is not in A?
Excelent explanation. One small question not related to the subject. What is the tool to draw like a white word using a hand as a pointer and seams like not using a mouse , but real hand writing? :)
Use a tablet or a bamboo tablet with a pen (it's own pen). I have those and they usually used by animators. And this can be recorded by any good screen recorders like camtasia... that's all I got.
i dont get it.we have subset and strict subset. subset is when all of B is in A.strict subset is when all of B is in A and there are other elements in A. so by this logic the only time when B isnt a strict subset of A is when they are equal? why then have a normal subset if you can just use equals sign? Coz you cannot have B is a subset of A if there isnt the same or more numbers in A than in B. and when there is more in A its a strict subset,when its not its equal.i dont get it? why use subset?
Why use greater than or equal to sign when there already exist signs which cover both relations? This is basically the same question but with different set of relations. The thing is, those relations are still sometimes useful. I mean who knows, you might, one day, run into a task with two unknown sets A and B for which there is a property A is a subset of B, but not necessarily strict, all you know is that A is a subset of B,and then you need to prove some property. Idk if I explained this well enough but you may understand what I exactly mean.

Wonderful. More on sets, please.

Sal is the coolest teacher I've ever had.
Men like Sal should be leaders of nations, I swear.
4:24 indicates me learning is funny if you got the concept,then you get comfortable 😊
Thank you sir
I have a test tomorrow. Thank you.
Ty
Wonderful. Thanks !
THANK YOU
thankyou very much khan academy

Nice ending
Does this specific person doing the video have his own page where I can watch different math videos where he specifically is giving the lesson?
Good explication man 🤓🧠👍
fundamentals are explained beautifully
Thx you this video help out so much
I have a ❓ I have A=(1, 2, 8)
B=(2, 4, 6)
C= (1, 2)
As far as I can understand,
"A is the superset of C" right?
If someone can answer please (thank you)

Thanks Sal 💯
Is C a superset of A? Because earlier you said that it's not a subset, but in this case we change the notation of the problem.
I love your videos they help me all the time refeashing material for a test
This is great, thanks

will a set still be a subset to another set if there is one extra element not in the other set. for example A= (1,2,3) B = ( 1,2,4 ). So will B still be a subset of A even though there is an element that is not in A?
Cool
old video but invaluable help. 4mins to explain 3 hrs of lecture from my professor
great
AYoo ..can you do somee Technical Drawing?
Excelent explanation. One small question not related to the subject. What is the tool to draw like a white word using a hand as a pointer and seams like not using a mouse , but real hand writing? :)
Mongols: Genghis Kahn is the one and only Great Khan!
Sal: *Hold my mouse.*
Never seen proper subset denoted that way. I've always seen it as the ⊆ without a line under it like this "⊂"
so if I have to constrict two subsets B. that would be just two sets in two separate brackets
Can B be a subset of A and A be a subset of B at the same time? If so what is an example?
Yes, but it would have to be a STRICT subset of A (A contains all of B and some) and a subset of B (B = B).
This situation occurs when A=B
This is so confusing OMG

Don't miss the exclusive interview with Binance's CEO for a glimpse into the future
What is the math called that this belongs to? What do you call it in english?
I believe it is Discrete Math
Ah, man. Sal's voice.
Use a tablet or a bamboo tablet with a pen (it's own pen). I have those and they usually used by animators. And this can be recorded by any good screen recorders like camtasia... that's all I got.
POWER sets? :)
Can't we say that C is a strict subset of A ?
C is not even a subset of A bcuz C has not each element that is in A

But you explain it in 3 mins

try an ipad or some kinda tablet i guess
Ganx man
this video is almost older than me lol💀
Taughtology..! Sort Of..!
This subset topic makes me really upset..
😮
guys activate number lock then spam 3 💀💀💀💀💀💀💀💀
I meant 6
you mentioned wrong b is not superset of c it is strict superset only i doesnt have 19 i should have completed the video first you corrected your self
if you did all those drawings on a mouse muose
