Hi i've got a formula in which part of it look's like this:

11

x

----

11!

where x is the variable for the power. Would anyone know the purpose of the ! (not) on 11, and what effect it would have on it?

Thanks.

Not sure what you mean.

In mathematics, ! is the factorial operator.

n! = 1 * 2 * 3 * 4 * ... * (n - 1) * n

(special case: 0! = 1)

examples:

2! = 1 * 2 = 2

4! = 1 * 2 * 3 * 4 = 24 - 10-05-2002Cassius
Right so

11! would be: -

1 * 2 * 3 * 4 * 5 * 6 * 7 * 8 * 9 * 10 * 11 = 39916800? - 10-05-2002Magos
*checking the number on my calculator*

Yep, that's true! - 10-05-2002Cassius
Right thanks, you've sorted the problem out for me!
