My new high score: 5! 8)
I usually have to play for a while before I get a good run; a good run being one where no planets come up.

Presumably that's his new high score without cheating.

And 5! = 120.

What does ! do to numbers anyway? I could never figure it out.stitch626 wrote:Um, actually 4! = 24.Mikey wrote:Teaos wrote:Woot I got 4!You guys mean in the Sudden Death, or just counting?Rochey wrote:My new high score: 5!

I got 10! Um... I mean 10.

1!=1 2!=2x1=2 3!= 3x2x1=6 etc. etc.

It's called factorial and, as Shran has just pointed out, you calculate it by multiplying all the integer numbers from 1 to the number specified together. For example:
1! = 1
2! = 1 x 2 = 2
3! = 1 x 2 x 3 = 6
4! = 1 x 2 x 3 x 4 = 24
5! = 1 x 2 x 3 x 4 x 5 = 120
6! = 1 x 2 x 3 x 4 x 5 x 6 = 720
7! = 1 x 2 x 3 x 4 x 5 x 6 x 7 = 5,040
8! = 1 x 2 x 3 x 4 x 5 x 6 x 7 x 8 = 40,320
9! = 1 x 2 x 3 x 4 x 5 x 6 x 7 x 8 x 9 = 362,880
10! = 1 x 2 x 3 x 4 x 5 x 6 x 7 x 8 x 9 = 3,628,800
as you can see factorials get big very very quickly, even faster than geometric progressions.
1! = 1
2! = 1 x 2 = 2
3! = 1 x 2 x 3 = 6
4! = 1 x 2 x 3 x 4 = 24
5! = 1 x 2 x 3 x 4 x 5 = 120
6! = 1 x 2 x 3 x 4 x 5 x 6 = 720
7! = 1 x 2 x 3 x 4 x 5 x 6 x 7 = 5,040
8! = 1 x 2 x 3 x 4 x 5 x 6 x 7 x 8 = 40,320
9! = 1 x 2 x 3 x 4 x 5 x 6 x 7 x 8 x 9 = 362,880
10! = 1 x 2 x 3 x 4 x 5 x 6 x 7 x 8 x 9 = 3,628,800

They're one of the few maths things I actualy remember. 
I've also seen "!=" to mean "not equal to. For example: X != Y. Though I prefer "=/=".

It's all a matter of where you put the !, so 4 != 23, but 4! = 24. And yes, =/= makes much more sense, since it's a proper mathematic sign (or at least an approximation of one).
Re: Sudden Death

Agreed. Though in many cases you can tell from the context what they mean. Still, =/= is easier to read in a hurry. I think I've only seen != used by those crazy Yanks, anyway.

You have to avoid confusing computer programming languages with mathematical notation. != is a programming item, it comes about because ! in certain languages means 'not', thus != is 'not equal to'. It is also often written as <>. I don't know of a computer language that uses ! to mean factorial.
