Math brainlet here. Explain to me how everything aside from addition and subtraction aren't just increasingly more complex shortcut ways to add and subtract?

Same of them don't even have numbers but I'm also a math brainlet so I don't get it either

There is no definite answer, but category theory is very abstract.
>>
Antisymmetry can be somewhat abstract, whilst not a branch of mathematics in itself, it’s a fundamental property or concept used within several branches of mathematics

Tbf the idea of category theory being very abstract is mostly propaganda by the set negros. It really is a lot more lucid than other areas of research. Idk though because I can't speak for those that got filtered by it.
>>

You're a fucking idiot, and have barely touched any category theory.

>>16926982
fine. use KEKegory theory to determine the full closed form formula of the logistic map for any r in real numbers.
[math]
x_{t+1} = r x_t(1-x_t), \qquad t \in \mathbb{Z}_{\ge 0}\\

Find \ x_t \text{ explicitly in terms of } t,\ r,\ \text{and } x_0,
\quad \text{for all } r \in \mathbb{R}.
[/math]
It's useless bullshit if it does not spit out a formula with the elementary functions and pure function of t.
>>
>>16927061
So what? The point is that it's abstract, you stupid faggot. Learn to fucking read.

to all you maff lovers lmao how does it feel behind at the asswhole of scientific progression??? when you think about inventions its always the brainiacks at physics, geology or chemistry who are the frontrunners.
in other words, you have no real impact on our lives.
how does it make you feel.

A lot of math is just setting up a bunch of assumptions (axioms) and then finding out what follows from them (theorems).

If you picked good assumptions, they are gonna apply to real problems people are trying to solve, and your theorems are going to give people an answer to their problem or a shortcut to apply in solving a particular instance of a problem.

For example the pythagorean theorem. It is useful for measuring distances and used all the time in practical settings.

You can derive it from a bunch of assumptions called Euclid's postulates. One of them, known as the parallel postulate, only holds in a certain type of flat space. So if you have a flat triangle, you can apply the PT.

But say you want to measure the distance between two points on earth, one of which happens to be on the equator. You can draw a triangle with a right angle by drawing a line from that point along the equator until you hit the longitude of your second point and then going straight north or south until you hit that point.

But now the PT trick won't work, because you are trying to measure distances on a sphere. You need a different theorem that you derive from slightly different axioms which are compatible with spheres. Lucky for you there are mathematicians who have figured that shit out.

Even what addition and subtraction mean depends on axioms we have set up about their behavior. Depending what type of things you are trying to add or subtract, they might behave differently.

So basically that is the reason there are so many different branches of math. They start out with different assumptions and build theorem's upon theorem on top of one another that song other things give physicists and computer scientists and evolutionary biologists and engineers and the mathematicians on the other branches tricks and shortcuts and results to work with.

there is literally a branch of math called abstract algebra. However, it is not the most abstract branch of math and something you'll probably learn eventually as part of any rigorous math or science program.

For truly abstract logic that will fuck you up you'd want to look into either algebraic geometry or pure number theory. Algebraic geometry is the study of abstract geometric concepts that you can't even call "shapes" anymore, they're just mapping out symmetries and holes. Pure number theory gets pretty wild when you start learning about the zeta function and the Reimann Hypothesis, there's a reason why prime numbers turn ambitious mathfags like myself into schizos, that's all I will say.
>>
>>16926798
NTA but why the fuck is math formatted in such an unintuitive way? Like look at formulas and shit, why the fuck do I need to basically learn a different language to understand what all these symbols mean? Surely there is a better way to format this shit in a way the human brain can immediately comprehend it.
>>
>>16928385
It is intuitive to intelligent people that were meant to be doing it. Speak for yourself. You're just fucking retarded and so are most people. Not everyone was born to be a fucking soldier or a musician or a poet or a singer. Maybe this shit just isn't for you bro. Maybe you should quit and focus your life on something appropriate for someone stupid like you, like serving me my fucking coffee.

That's a good question. Depends on your definition of "abstract".

If you mean the opposite of "applied", i.e. most inapplicable and useless, then it's category theory.

But in case you meant absolutely nonsensical garbage and autofellatio, then it's ceirtainly [spoiler]category theory[/spoiler].
>>
>>16928400
>another retard that got filtered by undergrad math
name one "application" of set theory that isn't also an application of category theory.

I'll wait.

If I wanted an answer from a prick I'd pull mine out of your mother's ass and ask it instead.

If I gave a fuck what you wanted I'd go out of my way not to do it just to see your life be slightly more miserable than you make it yourself by way of your own fucking stupidity.

That's no way to talk to your father. Don't make me roll off your mother and get my belt.
>>
>>16928407
I'm talking to you. A schizo on the internet with no math skills who does not belong anywhere on this website. You are not anyone's father, nor will you ever be. You will not have sex with another human being, and you probably will not even get a chance to fuck any kind of animal at all.

>you probably will not even get a chance to fuck any kind of animal at all.

>>16928414
Once again, I am talking about you. Not my mother, or any other delusional schizo fantasy playing out in your feeble mind right now. Keep cooking buddy.

Imagine, if you spent this much effort reading a fucking math textbook you might actually develop the intuition for basic arithmetic you lack from birth.
>>
>>16928416
>Keep cooking buddy.
That's your mother's job, I'm just in the kitchen because that's where her ass is right now.
>>
>>16928418
It is her job, and she's quite good at it. Your ass, on the other hand, is only in a "kitchen", if that's what you call shitting in your diaper.

Keep the cope going you tar black gorilla nigger. I got all day.

>shitting in your diaper.
Thanks for the reminder, I should grab some, she'll be needing it after I finish with her butthole.

>>16928422
Just remember to also pick up your psychosis meds when you go out. You'll want to take those at some point so when you're done masturbating alone in the dark you remember to throw away the watermelon you wrote "anon's mom" on instead of eating your own semen like the dumb nigger you are.

>>16928423

I shoved a glowstick in her first, it's not that dark now. I feel like my dick is an earthworm exploring a new mud tunnel.

Oh look you found words that rhyme, that's impressive! Looks like we found out your intuition is for shitposting, not math? Many such cases! Now you can go be a happy shitposter on reddit and kindly fuck off.

Look the only math I know is 1+1 = my dick where she poos.

>the only "math" I know is shitposting
Which is why it makes sense you need to leave and stop posting here. This is a board for math and science, not your fucking attention seeking retardation. That's what reddit is for actually, now fuck off and go there.
>>
>>16928441
I'd leave but I'm stuck, can you reach under the 18th fat fold on her stomach and yank out the stick of butter she keeps there?
>>
>>16928443
Don't worry, I'm sure someone on this website will help you leave shortly.
>>
>>16928444
I hope so, I can feel her frosted turd starting to crown.
>>
>>16928446
No need for hope. Just be patient.

I can formalize an entire cat theory book as a set of sets of symbols, define corresponding axioms and deduce all your rubbish, both thinkable and unthinkable.

Basically, that's what LLMs are already doing.

Nice application, innit?

I'd say you're projecting, but that would imply there's a constructable sheaf somewhere in category theory for whatever the fuck you're on about that does not exist in set theory, or maybe you didn't read my post

or maybe, as I suspect, you don't actually know what category theory is, but you think you do for some stupid reason
>>
>>16928385
do you have any idea how verbose natural language is? Ever read Kant? That is how math would read in natural language, and it would need translation from language to language. That is why it is symbolic.
