Alternate proof to induction for integer sum | Precalculus | Khan Academy

[@nus7935]

This just made my life a lot more easier. Thank you for that.

[@andreypopov6166]

This one is much more intuitive than "by Induction", at least for me. Thank you!

[@originalsqueekr766]

This proof made me laugh, neat.

[@Abdaddy]

why is there have to be dislikes in every video. wt f people dont appreciate stuff.
thanks for making algebra fun sal :)

[@kairu86]

So easy to understand! Thank you!

[@Waranle]

Hi Sal, why not do a whole course of discrete math? thnx anyway

[@sankojuprithvi]

Genius video on mathematical induction

[@mcrlover429]

Do you have a video for strong induction? I'm so weak in that.

[@HughJazz13]

Proof by deduction...always showing us how to do something but leaving out some of the most important details!

[@roryboytube]

anyway these videos could be referenced nunbered in order to locate them on TH-cam?

[@junior1984able]

@Khanacademyr0cks he does have physics , chemistry, and biology, go to his website....

[@doerrthecricket]

Does this method work for proving all sums, or just a few simple ones?

[@yasinhamad5982]

thank you

[@dimanabok]

Thanks!

[@charleszr853]

why do u divid both sides by 2?

[@Peter_1986]

There is no real reason to do harder examples, because if you understand these videos then you can apply it to any induction problem, at least if you have an intuition for it.

[@wetbadger2174]

I literally have no idea how to do induction except for a summation function. I am probably just too stupid to do this kind of math.

[@BrokeButBullish-f9e]

how to even think of this kind of thing, where to start? I am baffled

[@schaz7563]

Well played homie
