Harvard University Admission Entrance Exam Tricks.

That was impressive. You gave me a new way to figure out these types of equtions that I never thought of. It looked like it would be a lot faster than the method I would have used. It has been over 40 years since I took math course and I rarely do math by hand any more. Thanks

This is one of those problems where the powers of 2 up to the 32nd power come handy to know, especially when all computing is based on binary language.

2^24-2^20= 15*2^20=15*1024*1024

Why Harvard don't have calculater?

[@markhirschmann9967]

Because any idiot can stick it in a calculator,but not everyone understands the maths behind it.

[@johnshaw6702]

Because if you can't do it without a calculator, you don't know what you are doing.

Antes de que termines de hacer este video yo ya lo habia resuelto en la forma tradicional y en la mitad de tiempo que tu tardaste...La distancia entre 2 puntos es la linea recta, no lo olvidemos....

Whoa!! Thats well done Sir! I'd have to watch that twice to keep up. I'm sure Boeing's got a great career path for you. Nah wait, Maybe NSA or the CIA....Hmmm, maybe no. Hey, Call Elon!!!Bet he has a spot!

Many thanks!

I stopped at 15 * 16^5. The rest is calculating, not mathematics. 😁

[@lucien346]

Very good 😁

[@learncommunolizer]

Thank you very much 🙏♥️🙏

[@Tigers93349]

COOL

[@ahmedabbas8371]

Last you said 15 724 640 😂

[@learncommunolizer]

😂😂😂

[@jackieking1522]

That took me two lines and I skipped 7.22 of your video. Did you do it the quick way?

[@oraach]

The rest of us need to learn from first principles

[@albertfigueresgiral8373]

64⁴-16⁵=(2⁶)⁴-(2⁴)⁵=2²⁴-2²⁰=2²⁰×(2⁴-1)=2²⁰×(16-1)=2²⁰×15

[@mukhomor9937]

Ну или так. Ну это работает, если можно к одному значению подвести. А если нет? Если вместо 16 стояла бы 13, а вместо 64, скажем, 61? И накрылась ваша лавочка.

[@mukhomor9937]

И на хрена такие сложности, если можно тупо посчитать? 16 777 216 - 1 048 576 = 15 728 640

[@iulianmihai9367]
