Nope, according to that a negative factorial would have an undefined value due to division by zero.
-5! does exist: -1 x -2 x -3 x -4 x -5.
-1 x -2 = 2.
2 x -3 = -6.
-6 x -4 = 24.
24 x -5 = -120.
So the answer is negative(120).

http://en.wikipedia.org/wiki/Factorial might help.
I might return for a little while.

Who knows how to do an equation like:
5!
5!=120
Explanation: ! (Factorial) Means you multiply the number by every counting number with a lesser value than it.
Ex:4!
1x2x3x4=48
Your music tastes are bad, therefore your argument is irrelevant.

So the answer is negative(120).
Are you sure?

Hm... nope. Put (-5)! in a calculator; it returns an error.

-5 is the value 5 places below the 0 value.

Re: Lets see who knows this kind of math...
It's called five bang or five factorial, so 1 x 2 x 3 x 4 x 5.
1 x 2 x 3 x 4 x 5 = 120.

Let's count.
8, 16, 24, 32, 40, 48, 56, 64... You're correct.
