The Best 0,1,2,3,4,5,6,7,8,9 Combinations #shorts

There's not much to simple combinations with no replacement... if we take the 10 digits from 0 to 9, we can arrange them nearly 4 MILLION ways by using 10!. When we take the subset of squared digits that result in a unique combination of those 10 digits? Now we're down to just 87 numbers n, all of which contain 5 digits.

You could find them all by hand, calculating every squared whole number until you got a value larger than 10 digits (and don't forget, all of them need to be unique), but over 50 years ago the IBM 1620 used its 1,200+ pound frame to work it all out. Do it by hand. What else do you have to do?

Really thought he was gonna go for the “that’s about the same weight as your mom” at the end, narwhal will do though

[TheAsianOne]

My “science” teacher once denied narwhals being real

[veertien]

Narwhals, Narwhals
Swimming in the ocean
Causing a commotion
'Cause they are so awesome

[MrPerfs]

Kevin: How does one human mind discern exactly the right amount of punishment?

Also Kevin: NARWHAL! NARWHAL!

I'm a little unclear as to what "squaring another digit" means. I assume you mean "squaring a number"?

[yashrawat]

I can conjecture 2 things :
1) All such numbers are atleast divisible by 3
2) It won't contain a number that ends with 0

[zarporiko]

10! ? NOPE, Numbers cannot start with 0 so it should be 10!-9! Which is 9*9! = 3, 265, 920

I expected better from you Kevin :(

[ocashflo]

I’m always fascinated by your videos and lots of times blown away! BUT what is this even useful for?

[xMrKadik]

I think you missed the fact that you can't start the numer with 0, so the actual number of those number is 9! times 9 (you can only use 9 numbers for first digit)

So the actual number of combinations is 3265920

[leftylizard]

Are none of those 87 numbers 9 digits with a zero out in front?

[Jaden_Ivy]

He shoulda made that more clear, and said only 87 are a perfect square

[PaulsPubAndBrew]

Is this right? 10! Means the 0 could go first which it can't. Wouldn't it be 9 * 9! Since only 9 digits can come first and then you have 9 remaining? That's 3, 265, 920.

[BryndanMeyerholtTheRealDeal]

Is a number like 0 bil 123 mil 456 tsnd 789 allowed?

[jadenruanes]

How did you get these colorful numbers?

[matman]

Narwhals must be a lot smaller than I imagined them to

[YourSooFakeSauce]

how is it a death match..? I'm confused.

[DragonslayerProd]

Are there any that are the product of two 5-digit numbers that don't share any digits?

[DanFarrell]

You can’t just say numbers for 60 seconds and call it entertainment

[santiagoruiz]

Wouldn't it be 9! Since numbers starting with zero are not written like that?
