I know nothing about other stuff,

Well apart from Wallace and Gromit and Terry Pratchett.

Just to say well done Doc, this is a great thread.

Hi

Factorials

4

4x3x2x1=24

5
5x4x3x2x1 = 120

Hope this helps.

Re: Question 8

So the factorial of 6 would be...

6x5x4x3x2x1=720?

Re: Question 8

Sorry, but I feel that it is something that I DONT need to know.
I mean what use would I have for it?

Re: Question 8

Hi

Yes, spot on.

I cannot, sing or dance or play a musical instrument, useless I am, just a geek.

Re: Question 8

I tend to agree, although I suppose that a mathematician would assure you that factorials have some sort of practical use.

Actually, I thought I'd google it and found this:

but unfortunately I think it must be in Chinese.
