Was math discovered or invented ?

@33person Leopold Kronecker famously said “God created the natural numbers. All else is the work of man."

@helenS And I'd even say humans invented the numerals used to denote those numbers.

@33person Yes.
By the way transcendental number such as π are not invented. They are discovered.
Do you celebrate π day?

@helenS Of course I do! You?

@33person Yes:

@helenS Transcendental numbers often reflect a certain mathematical reality such as the ratio of the length of a circle to its diameter (pi) or the ratio of the length of a diagonal of a square to a side (square root of 2).

Was mathematical reality invented? No but the notation or words we use to refer to mathematical reality are clearly invented and somewhat arbitrary.

@Alfred22 sqrt(2) is not a transcendental number, because it's one of the 2 solutions of the equation
"x^2 – 2 = 0".
It's an irrational number though, or, more specifically, an algebraic number; see, for example,

@helenS Apparently Kronecker thinks God doesn't understand circles...or waves...or...

@SomeMichGuy Sorry but I don't understand. Kronecker??

@helenS ? Refer to your quote of Kronecker...

@SomeMichGuy Oh – now I get it. Thank you!

@helenS np and ebenfalls ⚘
