Introducing, the signed factorial: ¡n! = n × -(n-1) × (n-2) x -(n-3) x ... x (-1)^(n-2)(2) ×(-1)^(n-1)(1)

Where’s our Nobel prize.

There's no Nobel price for mathematics, but I can accept the one for peace instead.

I heard biology branches out.

I'd prefer an alternative definition that starts with the base case ¡0! = 1, and then for n > 0 we define ¡n! = n * -¡(n-1)!

[-] kittehx 5 points 2 weeks ago
