I don't think the maths checks out

[–] mmddmm@lemm.ee 20 points 2 months ago

Maybe, maybe not. 0/0 can actually approach any value, so if the OP says it's perfect, well, I can't disagree.

Proof by comic

[–] wischi@programming.dev 66 points 2 months ago (3 children)

0/0 is undefined because everything would be a valid result. 0/0 is basically finding solutions for 0*x=0 and everything you put into x would satisfy the equation.

[–] InFerNo@lemmy.ml 4 points 2 months ago

It should be 0/2 because out of the 2 things, they have 0.

[–] BleatingZombie@lemmy.world 2 points 2 months ago

Thank you! I've always wondered what the answer would be and why. 0 divided by a number is 0. A number divided by itself is 1. A number divided by 0 is undefined. I never knew which one took precedence and why

[–] kogasa@programming.dev 2 points 2 months ago

This doesn't clearly identify a problem IMO. Division by a number is defined as multiplication by the multiplicative inverse, and 0 has no multiplicative inverse because 0x = 1 has no solutions.

[–] Sludgehammer@lemmy.world 40 points 2 months ago (1 children)

0/0 is undefined, not zero.

[–] abfarid@startrek.website 9 points 2 months ago (1 children)

Indeterminate, to be precise.

[–] kogasa@programming.dev 5 points 2 months ago (1 children)

Undefined is more precise. 0/0 being an "indeterminate form" refers to expressions of the form lim(x->c) f(x)/g(x) where lim(x->c)f(x) = lim(x->c)g(x) = 0.

[–] abfarid@startrek.website 3 points 2 months ago

After some quick research, I tend to agree with you.

[–] zipzoopaboop@lemmynsfw.com 38 points 2 months ago

MATH DOES NOT WORK THAT WAY.

GOODNIGHT

[–] Leate_Wonceslace@lemmy.dbzer0.com 14 points 2 months ago (5 children)

Okay, so I had a personal project for a long time that addressed the potential for an algebra that allowed for the multipicitive inverse of the additive identity.

In the context of the resulting non-associative algebra, 0/0=1, rather than 0.

For anyone wondering, the foundation goes as such: Ω0=1, Ωx=ΩΩ=Ω, x+Ω=Ω, Ω-Ω=Ω+Ω=0.

A fun consequence of this is the exponential function exp(x)=Σ((x^n)/n!) diverges at exp(Ω). Specifically you can reduce it to Σ(Ω), which when you try to evaluate it, you find that it evaluates to either 0 or Ω. This is particularly fitting, because e^x has a divergent limit at infinity. Specially, it approaches infinity when going towards the positive end and it approaches 0 when approaching the negative.

There's more cool things you can do with that, but I'll leave it there for now.

[–] kogasa@programming.dev 5 points 2 months ago (1 children)

There's not much coherent algebraic structure left with these "definitions." If Ωx=ΩΩ=Ω then there is no multiplicative identity, hence no such thing as a multiplicative inverse.

[–] Leate_Wonceslace@lemmy.dbzer0.com 1 points 1 week ago (1 children)

No; 1 is the multiplicative identity.

1Ω=Ω, and for all x in C 1x=x. Thus, 1 fulfills the definition of an identity.

[–] kogasa@programming.dev 1 points 1 week ago (1 children)

1 = Ω0 = Ω(Ω + Ω) = ΩΩ + ΩΩ = Ω + Ω = 0

so distributivity is out or else 1 = 0

[–] Leate_Wonceslace@lemmy.dbzer0.com 1 points 1 week ago (1 children)

Correct; multiplying by Ω doesn't distribute over addition.

[–] kogasa@programming.dev 0 points 1 week ago (1 children)

Distributivity is a requirement for non associative algebras. So whatever structure is left is not one of those

[–] Leate_Wonceslace@lemmy.dbzer0.com 1 points 22 hours ago* (last edited 22 hours ago) (1 children)

What the fuck are you talking about? That's incorrect as a matter of simple fact.

Associativity is a property possessed by a single operation, whereas distribution is a property possessed by pairs of operations. Non-associative algebras aren't even generally ones that posses multiple operations, so how the hell do you think one implies the other?

Edit: actually, while we're on it, your first comment was nonsense too; you don't know what an identity is and you think that there's no notion of inverses without an identity. While that's generally the case there are exceptions like in Latin Squares, which describe the Cayley Tables of finite algebras for which every element can be operated with some other element to produce any one target element. In this way we can formulate a notion of "division" without using an identity.

[–] kogasa@programming.dev 1 points 21 hours ago (1 children)

Algebras have two operations by definition and the one thing they have in common is that the multiplication distributes over addition.

Yes, there is no notion of inverses without an identity, the definition of an inverse is in terms of an identity.

Stop posting.

Do you think a group isn't an algebra? What, by your definitions make an "Algebra" different from a "Ring"?

[–] merci3@lemmy.world 4 points 2 months ago

my brain hurts

[–] prettybunnys@sh.itjust.works 3 points 2 months ago

How did you correct for parallax amete-gramejons?

[–] CompassRed@discuss.tchncs.de 3 points 2 months ago (1 children)

Interesting. I think it isn't unital either otherwise Ω=0.

0=Ω+Ω=Ω+ΩΩ=Ω(1+Ω)=ΩΩ=Ω

[–] Leate_Wonceslace@lemmy.dbzer0.com 1 points 1 week ago (1 children)

Someone else had the same observation, but it is unital. Keep in mind that it isn't associative; you can't pull out the Omega like that.

[–] CompassRed@discuss.tchncs.de 1 points 1 week ago

The definition I'm aware of for non associative algebras has them distributive by default, so I believe the chain of equations is valid.

[–] Danitos@reddthat.com 2 points 2 months ago (1 children)

That seems interesting. Do you have any material/link/blog on this?

[–] Leate_Wonceslace@lemmy.dbzer0.com 2 points 1 week ago (1 children)

No, I'm pretty shy about my work in-person and I don't like linking my online and IRL self. Do you have any recommendations for places to put my work?

[–] Danitos@reddthat.com 2 points 1 week ago (1 children)

Sadly, no. However, you could maybe do a personal blog, similar to how Terrence Tao does.

I really encourage you to try, it could help you find new stuff, check for mistakes, clarify ideas, and maybe even hear ideas from others.

[–] Leate_Wonceslace@lemmy.dbzer0.com 2 points 1 week ago (1 children)

I appreciate your encouragement; it's an extremely rare occurrence when I discuss my ideas with others. I'll think about what you've said and if I follow through I hope to remember to send you a message. I'm favouriting this comment so I can find it again.

[–] Danitos@reddthat.com 1 points 6 days ago

That'll make me really glad :)

We can also exchange contact information via private message if you want to.

Bit stupid we’re still calling video gaming having “no life” when it’s substantially more fulfilling than pretending to have a life you don’t for fake internet points from fake internet friends on fake internet communities. I’ve met plenty of interesting people and developed lasting relationships gaming. And it’s stimulating mentally depending on the genre. Meanwhile, I go out to social settings and see half the people sitting alone, posing with food and drinks and doing nothing but staring at their phones. Some life.

[–] SubArcticTundra@lemmy.ml 8 points 2 months ago (1 children)

If no work is beyond your means you can opt for the equally balanced shit work and shit life.

[–] umbrella@lemmy.ml 1 points 2 months ago

my favorite

[–] ZILtoid1991@lemmy.world 5 points 2 months ago (1 children)

You mean the nazi supporter?

[–] Shortstack@reddthat.com 3 points 2 months ago

This dude does have a job, it’s playing whatever game that is everyday

Westerners are late to the game. Chinese people are already doing it: https://en.wikipedia.org/wiki/Tang_ping

[–] hungrythirstyhorny@lemmy.world 1 points 2 months ago

thats my purpose in the future

im working now, to have no work and no life

[–] 4oreman@lemy.lol 1 points 2 months ago

is this about applying for jobs?

[–] absGeekNZ@lemmy.nz 0 points 2 months ago (1 children)

Is could be argued that 0/0=1
since x/x=1
Subbing in x=0 gives the above.

Complicating things is x/0=infinity
Subbing in x=0 gives a contradictory answer.

[–] Ibuthyr@lemmy.wtf 3 points 2 months ago (1 children)

Anything divided by zero is undefined.

[–] absGeekNZ@lemmy.nz 0 points 2 months ago

Yep, infinity is not a defined number.

1/0=?......how many times does 0 fit into 1?
