¡Nobody expects the Spanish notation!

Fuck I thought that was an absolute factorial.

[–] [email protected] 7 points 7 months ago (2 children)

Aren’t all factorials absolute factorials?

[–] [email protected] 14 points 7 months ago* (last edited 7 months ago) (2 children)

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

We did it Lemmy!

Where’s our Nobel prize.

[–] [email protected] 10 points 7 months ago (1 children)

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

I heard biology branches out.

[–] [email protected] 8 points 7 months ago* (last edited 7 months 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)!

How are you going to flip the signs though?

[–] [email protected] 5 points 7 months ago

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

it's fixed now

[–] anarchrist 6 points 7 months ago

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.

[–] Redjard 8 points 7 months ago

Why not both?
n! / k! ¡n-k!

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

[–] [email protected] 7 points 7 months ago (2 children)

Whyd you use curly brackets then?

[–] [email protected] 6 points 7 months ago

¿{Did I thought}?

[–] [email protected] 5 points 7 months ago

Because they become invisible in LaTeX

[–] [email protected] 18 points 7 months ago

jajaja

[–] [email protected] 8 points 7 months ago

Kinky

Spanish mathematician! Is this for real?

[–] [email protected] 3 points 7 months ago

No.
