0 = 1
You know, I needed to post.
It's an addiction.
0! = 1.
Boy let me tell you what:
I bet you didn't know it, but I'm a fiddle player too.
And if you'd care to take a dare, I'll make a bet with you.

Re: 0 = 1
0! was defined during the following conference between the world's finest mathematicans:
Seriously though, the best argument for this is that 3! = 3 x 2!, 2! = 2 x 1!, so 1! = 1 x 0!, meaning 1=1 x 0!, meaning 0! = 1.

Why did the vector cross the road?
It wanted to be normal.

Re: 0 = 1
3! = 3 x 2!, 2! = 2 x 1!, so 1! = 1 x 0!, so 0! = 0 x (-1)! ????
Negative factorials are undefined, but then some of the greatest advances in math have occurred when people have thought, "yes, but what if it was possible?" ... for example imaginary numbers, and fractals (fractional dimensions).

Re: 0 = 1
If 0! = 0 x (-1)!, then (-1)! would be 0! / 0, which is indeed undefined. The pattern still works!

Re: 0 = 1
it is essential that 0!=1 in combinatorics, otherwise a lot of things won't work

Re: 0 = 1
0 = 1
and I can prove it and thus destroy mathematics for eternity ..... mauh hah ha ha ha ha
watch little kiddies as your perfect maths fails horribly
1 = -1 x -1 (I think we get that)
√1 = √(-1 x -1) (square root both sides)
= √(-1) x √(-1) (square root distribution rule)
= i x i (" http://www.google.com.au/search?q=square+root+of+-1 ")
= -1 (" http://www.google.com.au/search?q=i+multiplied+by+i ")
1 = -1 (√1 = 1)
1+1= -1 + 1
2 = 0
2/2 = 0/2
1 = 0
and there you have it!!! MATH IS DESTROYED MAUH HA HA HA H AH

Re: 0 = 1
Very good. I think the flaw is something to do with square roots needing a ± stuck to them, but still, it's a nice 'proof'.

Re: 0 = 1
Yes, I am indeed. lol 
Well done. heheh
I did know that my (deliberate) error is the (square root distribution rule) line.

Oh, wow! That is so cool.
