minus-squarejaybone@lemmy.worldlinkfedilinkEnglisharrow-up6·2 days agoAren’t all factorials absolute factorials?
minus-squaredriving_crooner@lemmy.eco.brlinkfedilinkEnglisharrow-up12·edit-22 days agoIntroducing, the signed factorial: ¡n! = n × -(n-1) × (n-2) x -(n-3) x … x (-1)^(n-2)(2) ×(-1)^(n-1)(1)
minus-squarekittehx@lemmy.blahaj.zonelinkfedilinkEnglisharrow-up8·edit-21 day agoI’d prefer an alternative definition that starts with the base case ¡0! = 1, and then for n > 0 we define ¡n! = n * -¡(n-1)!
