    Aren’t all factorials absolute factorials?

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

        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)!

          How are you going to flip the signs though?

      It’s the same calculation but you also take a shot of vodka for all integers less than n but greater than 0
