minus-squarejaybone@lemmy.worldlinkfedilinkEnglisharrow-up7·17 days agoAren’t all factorials absolute factorials?
minus-squaredriving_crooner@lemmy.eco.brlinkfedilinkEnglisharrow-up13·edit-217 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-squarejaybone@lemmy.worldlinkfedilinkEnglisharrow-up11·17 days agoWe did it Lemmy! Where’s our Nobel prize.

minus-squarekittehx@lemmy.blahaj.zonelinkfedilinkEnglisharrow-up7·edit-216 days 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)!
minus-squarejaybone@lemmy.worldlinkfedilinkEnglisharrow-up2·16 days agoHow are you going to flip the signs though?
minus-squarekittehx@lemmy.blahaj.zonelinkfedilinkEnglisharrow-up5·16 days agooop there was a real stupid typo where I forgot the minus sign lmao it’s fixed now
minus-squareanarchrist@lemmy.dbzer0.comlinkfedilinkEnglisharrow-up5·16 days agoIt’s the same calculation but you also take a shot of vodka for all integers less than n but greater than 0
