"The Hairs of Dwayne Johnson"
Thank you Khan, you made me love mathematics
Either the painter messed galileo’s face up, or he’s just downright ugly
My teacher doesn't teach the origin of Algebra and thus I take no interest in it, this popped off in my recommended and I'm thankful.
wait y is galileos hair black but his beard is white
😐
So you will not mention the "ORIGIN" of the workd "ALGEBRA"?
It made me crazy to conceptulize mathematics plssssss plssss upload algebra and geometry videos like this explanation😍😍😍😍🤩🤩🤩 plss humble request 🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻 pls pls pls pls pls pls pls pls
what book did Gallileo mean again?
Maybe it's my teacher but my dad says to watch Khan academy
uuum instead of 0.30 * x wouldent you put 0.70 * x
or i guess i should say
y * x
y=1-a
a=percent off
x=price of product
or just (1-a) * x (i think that works)
becuase 20*30%=6 and that is 70% of the price gone
while 20*70%=14 which is 30% of the price gone
I swear, this guy sounds like Ian Malcolm from Jurassic Park.
Anyone knows what device this guy is teaching on?
I had to leave the Khan link and find this video myself to compliment our speaker, lecturer and common Khan Academy host lecturer.
I cannot express enough gratitude (Huge Thanks!!) for both, your enthusiasm and your (attempt's at) elaborate efficiency in sharing
the slew of academics I have learned through you thus far!
I had monotone and worse, truly unknowing persons that "taught" math in my younger inner city education, so I am beyond refreshed to
continue my self education and more (Soon hope to test higher, then finish my bachelors & beyond.)with your brilliant and inspiring tutelage
and assistance .
Thank You for working tirelessly alongside the amazing
folks at Khan to create something special.
This video btw had a passionate and wow level finish!
😉
Hi there, Love your channel I'm a member. Can i ask you, what program allows you to bring up pictures or anything like you did here and freely draw on the screen thank you!
Isn't it a little more complicated though, due to the fact that 'a' in F=ma is a derivative of speed…?
I'm 25 with a science degree, im just here for the comments lol
What program is he using to write on his computer?
Good one
im forcing myself to study algebra rn so I won't have a stroke doing 8th grade math next school year. It is nice to be productive during quarentine time, tis tis
If we can use any symbol to represent the percentage off, and Sal said a number was a symbol . . . Then the equation wouldn't make sense, would it?
Thats a great video! I have a video about algebra with angles on my channel
like and subscribe if you guys think Khan academy is AMAZING!!!!!!!!!!!!!!!!!!!!!!!!
Math was a bit too fun back then…….
758 dislikes, can anyone explain why?
Thank you for posting this!!! I am 34 and I am trying to get into the Army, and order to do that I have to pass the GED!! Algebra wasnt my strong suit, but thanks to these videos I didnt have in school I can learn Algebra and a better way of breaking it down and understanding it. I was recommended this channel by some friends, so thank you for posting these 🙂
Thanks, Khan Academy! You have inspired me to make my own channel to help spread free education! Continue with this great work! If anyone wants to provide my channel with some feedback, I'd love the comments to help spread the free education model inspired by Salman Khan!
