Spanish Notations

23 comments

¡Nobody expects the Spanish notation!
Fuck I thought that was an absolute factorial.
- 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}!
- Whyd you use curly brackets then?
  
  ¿{Did I thought}?
  
  Because they become invisible in LaTeX
jajaja
Kinky
Spanish mathematician! Is this for real?
- No.
