PROOF: (Zero Factorial) = 1

BECAUSE I'M SO BORED IN MY HOUSE, I'VE DECIDED TO MAKE A VIDEO THAT WILL PROVE THAT 0! = 1

By the way, I am sorry if this short video has no sounds or whatsoever but this video will tell us that 0! = 1.

By the way, 1! = 1 (Check it in your scientific calculator to prove that 1! = 1). Also, check in in your scientific calculators that 0! = 1.

ENJOY THIS VIDEO!!! ^__^

at least i proved that 0! = 1

In fact, using the logic you just used, I could write 0!=0*-1!(as n!=n*(n-1)!), but this would be equal to zero. This is done for the sake of convenience. And I haven't found a convincing explanation of this. If anyone has, please tell me.

yay!!! i love math!!!

IVE DESTROYED THE BALANCE HAHAHAHA i liked it sorry gotta show some love for the effort

@Samcollins3 i agree with this kid. but very clever trick ima show my math teacher

dude it's wrong, 6! its not 6*5, its 1*2*3*4*5*6, so your prove is wrong sorry.

The property of factorials is that you take N and multiply it by N-1, then that-1, UNTIL YOU REACH 1. If you look at the property page, you can see that the set of numbers you multiply together when doing a factorial starts at the number given, and ENDS AT 1.

That means that, if N=1, it doesn't keep going. However, in the next slide you state N!=N*(N-1). That statement is FALSE when N=1; you've ignored the property of a factorial, that it stops at 1. 1!=1*(1-1) is false; 1!=1 is true.

think of it this way: there is only one way to do 1 thing, and there is only one way to do nothing. doing is the input, 1 is the output.

its true. calculator says it. google says it. indian mathematician says it.
