22:25 actually.

I've been in the Code Vault before. Or the RP Arena.

They both suck and serve no purpose =/

It's actually the number multiplied by every integer number before it down to and including 1.

So 4! = 4x3x2x1 = 24 etc.

You don't just give them the answer D: They'll never learn otherwise :(

Close, and kinda right. But what does the ! sign signify? What does it do to say 3 to get the answer 6?

1! = 1
2! = 2
3! = 6
4! = 24
5! = 120

See if you can find the pattern.

1! = 1.

Hence you can do a factorial of one, it just isn't very interesting. It certainly doesn't equal 2.

I can never understand how people can't do maths D: It's like the easiest thing ever. This is probably why in school I spent most of my time helping other people with their homework. Or their coursework in ICT. Or their biology homework in Upper Sixth even though I hadn't done biology in 4 years :S

Actually, I spent most of my time in school helping other people >_>

To be honest I only remembered when I was in a bank and the calendar on the wall (one of those one page for every day ones) said 11 September. I thought it was wrong xD Then I checked my phone and was like oh =/

I was at my aunt's funeral that day so I had more important things on my mind.

For those that don't know the correct notation for an index would be (for example) x^2 which means "x to the power of 2".

Putting a number or something in brackets implies multiplication and will just cause confusion.

See above.

When KHV reached the coolness level of a mathematics classroom.

Complex numbers works too :B(:

I presume by R you mean real numbers and by C you mean constants?

x^2 = -1

x = root -1

x = i

I forgot how much I love that film D: I'm going to watch it tomorrow =D

Never heard of it.
