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

[–] Venator@lemmy.nz 4 points 13 hours ago (2 children)

Whyd you use curly brackets then?

[–] anton@lemmy.blahaj.zone 1 points 2 hours ago

Because they become invisible in LaTeX

¿{Did I thought}?

Spanish mathematician! Is this for real?

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.

[–] Redjard@lemmy.dbzer0.com 6 points 15 hours ago

Why not both?
n! / k! ¡n-k!

¡Nobody expects the Spanish notation!

[–] anarchrist@lemmy.dbzer0.com 44 points 22 hours ago (1 children)

Fuck I thought that was an absolute factorial.

[–] jaybone@lemmy.world 6 points 18 hours ago (2 children)

Aren’t all factorials absolute factorials?

[–] anarchrist@lemmy.dbzer0.com 6 points 14 hours ago

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

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

[–] kittehx@lemmy.blahaj.zone 7 points 17 hours ago* (last edited 13 hours ago) (1 children)

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)!

[–] jaybone@lemmy.world 3 points 14 hours ago (1 children)

How are you going to flip the signs though?

[–] kittehx@lemmy.blahaj.zone 4 points 13 hours ago

oop there was a real stupid typo where I forgot the minus sign lmao

it's fixed now

[–] jaybone@lemmy.world 9 points 18 hours ago (1 children)

We did it Lemmy!

Where’s our Nobel prize.

[–] driving_crooner@lemmy.eco.br 8 points 15 hours ago (1 children)

There's no Nobel price for mathematics, but I can accept the one for peace instead.

[–] Randelung@lemmy.world 4 points 13 hours ago

I heard biology branches out.
