what if i disagree with 1+1 = 2?
math is only real if everyone believes in it.

it depends on base that you're using

prove to me that 1+1=2 , it should be easy.

grab 1 rock, grab another 1 rock, put rock together and count them. monke see monke think

don't be this guy

what do the rocks have to do with each other.

it's how adding works. you know what this mark (+) means... right ?

>it's how adding works
according to whomst'd've

you want to know how many rocks you have

to us, we learned how to add. and then gave it the term "Adding"

Take it from a mathematician. Mathematics is very real, it simply does not exist in our physical reality. It lies in a parallel platonic reality, an eternal world of pure mathematical beauty off of which our world is a poor copy.
In terms of 1+1, if you state for me your preferred axiomatic system I can prove within that system that 1+1=2 as long as it is strong enough to define Peano arithmetic.
Indeed, within Peano arithmetic, let 0 represent the empty set and let S be the successor function which, for a set, returns the set containing all the contents of the input set as well as the input set itself. (So S(A) = A U {A}). Then if we define 1 to be S(0) and 2 to be S(S(0)), as we are meant to, and if we define +1 to be applying S, then 1+1 = S(0)+1 = S(S(0)) = 2. In terms of sets, this says 1+1 = {0} U {{0}} = {0, {0}} = 2.

i have them? what do the rocks have to do with me?
rules that were made up. they are convenient rules and do a fine job of helping explain things, but still made up

+ IS THE MARK OF OUR LORD AND SAVIOR JESUS CHRIST

>a platonic reality
lol stopped reading there. pseud

(note that this is the formalism of Peano Arithmetic within any suitable set theory, of course one may adopt other theories as well, say a theory of categories or a theory of lambda calculus. In any such strong enough theory one may construct an analogous proof).

who said they weren't made up ? these were made up based on things that happen irl, and the whole purpose of making them up is to explain said-things that happen irl.

to the extent that human information processing is subjective and is a consequence of numerous factors such as human consciousness and the development of the ego. math attempts to quantify observable reality through truth values that are not hindered by obstructions like qualia and differing schools of thought

You didn't even read my proof?
I'm not a pseud, I'm a mathematician who happens to be a platonist.

you, in your right hand are holding a rock. in your left hand you are also holding a rock. you want to know how many rocks you are holding in total

>math attempts to quantify observable reality
no, observable reality attempts to qualify mathematics. you have the causality backwards.

the point is they were made up, and don't actually truly exist. the rules you made up aren't real, and the numbers aren't real, so 1+1=2 is something you cannot prove to be true. unless you believe math is actually real like this guy

math is a product of human cognition instead of an innate property of the universe, a language of logic designed to quantify the blueprint of natural phenomena. this is my understanding but i want to hear your thoughts on why it's the other way around.

so are you saying before we "made up math", a rock with another rock wouldn't make 2 rocks ?

math is simply the language to convey the proof that by adding two separate rocks together, you will have a total of two rocks, a way for humans to agree fundamentally that without question 1+1=2. things that can now be argued with mathematics had always existed but the necessity for understanding lead to the development of these truths to be organised in a such way that could be realised or falsified.

math exists and is real whether we made it up or not, you mentioned that
>they are convenient rules and do a fine
job of explaining things, but still made up
the terms, and numbers are made up. but the basis of mathematics is very real. and not made up. its like saying
>lol law of gravity is made up by isaac newton, therefore gravity isn't real
