    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)

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

  The Spanish notation makes the parentheses around n-k obsolete, clearly saving one symbol in some formulas is worth introducing a new one in others.

    Why not both?
    n! / k! ¡n-k!

  You don’t need brackets in the Spanish notation. ¡{That’s the whole point}!
