Well done. heheh

I did know that my (deliberate) error is the (square root distribution rule) line.

*Wikipedia saves the day.*

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

]]>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).

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.

0! = 1.
