Our new Indie Games subforum is now open for business in G&T. Go and check it out, you might land a code for a free game. If you're developing an indie game and want to post about it, follow these directions. If you don't, he'll break your legs! Hahaha! Seriously though.

Our rules have been updated and given their own forum. Go and look at them! They are nice, and there may be new ones that you didn't know about! Hooray for rules! Hooray for The System! Hooray for Conforming!

That would be above me then, I've only explored the Gamma Function to do fun things like take negative factorials, and complex factorials.

Well, a google search brings up this, which fits your criteria. Not exactly rigorous but logically sound.

KingAgamemnononKovakonimo

yourclothesonNo, I can't line up 0 objects in any fashion.

musanmanonhey asshole that is actually 1 way to line them up

Kovakonnotlining up 0 objects then well damn im pretty sure you broke everythingKovakonNone is 1. I LIKE THE CUT OF YOUR GIB SAILOR.

musanmanonOKAY to explain how none is possibly an option

YOU HAVE A CAKE

HOW MANY CHOICES DO YOU HAVE IF YOU CAN PICK FROM THESE ACTIONS

eat cake

not eat cake

nothing

KovakonyourclothesonyourclothesonKovakonJavenonActually in that case I think you have 2 cases. Nothing isn't really a choice because if it was, there wouldn't be a cake.

But I understand your idea "no ideas to line the up is the only option" = 1

My problem is the multiplication, and zero, is that when you multiply fucking anything by 0 guess what you get.

musanmanonNone

because cake is delicious

JavenonKingAgamemnononbut

why you gotta make me hit you baby

Kovakon(comic depicting a cake turning into a spy)

please give me money now

yourclothesonWhat about yellow sheet cake, with plain "white" frosting?

KingAgamemnononhonestly coming in and demanding that mathematical facts be proven without math is a bit like

going to church and asking the preacher to explain everything without god

or even speaking

he's just gotta wave his dick around

Kovakonthis cake comment is a lie

I've had like 1 cake that was delicious.

musanmanonKovakonok I'll show my hand...

I teach algebra and statistics and both of these subjects involve this discussion. You can't argue with 9th graders using mathematics like a gamma function. I am not satisfied saying "because"

I would like to keep the conversation going, so more points of view are better.

musanmanonHonestly, even the definition of the simple factorial function is defined from 1 to infinity and just sets 0! as 1.

My lining up way works as one of the simplest reasons to explain why it's gotta be 1 is in probability calculations.

There really is no "simple" and sound mathematical proof.

Your students need to learn that sometimes they just gotta accept something till they get smarter

KovakonKingAgamemnononWell...if you accept 1! = 1 then define the factorial function as x! = x * (x-1)!

so:

1! = 1 * (1-1)!

1 = 1 * 0!

1 = 0!

Nobody really has a problem with 1!, but fuck zero factorial.

musanmanonThe lining up is the best nonmathematical explanation I can think of

KovakonOne! Equals one.

Javenonill take care of your poor literature majoring self with my

hard scienceKovakonI scream. "6! is not SIIIIXXXXXXXXXX" it's 6*5*4*3*2*1

musanmanonJavenonthere are certain basic things you have to assume

KovakonI can rock geometry hardcore. There aren't a whole lot of assumptions there that's a definition.

Now rationalizing the denominator...we were big on "no negative exponents" so that's about my best defense but really, why do we do that.

musanmanonyourclothesonthere's no point to rationalizing

it's just kinda dumb really.

also. there are 5 assumptions in euclidean geometry.

Kovakongeometry is the sexiest no doubt...it pretty much created how we argue

musanmanonalgebra is like geometry's high class cousin

it's way sexier

KovakonThere are 5 basic postulates, P5 being the one that is "optional." That creates non-euclid geometry (when I say P5 I mean the one about assuming lines with less than 180 interior sum will result in an intersection)

musanmanonKovakonthat's what i'm saying.

That is just as much as saying 0! = 1

it's really almost as basic

KovakonI dunno I think of P5 as more of a fork in mathematics though. 0! = 1 is never really argued against. Nobody is like "well what is 0! was 0 let's create a branch of math"

I hate leaving students unsatisfied with "because it is" when math is sound enough to be explained.
