The correct answer, only $2$ and $\sqrt{-1}$ , is missing.

A, numbers don’t really exist what’s a “two”? Can you draw a picture of it? We have a symbol for it but that symbol doesn’t represent a real thing just an abstract concept like $\sqrt{2}, \sqrt{-1},$ and $\infty$ .

For something to exist it does not need to have a physical manifestation, it can exist as an idea.

Infinity is not well defined here. But say we're referring to positive infinity on the two point compactification of R or something. Then all of them exist. They just don't exist in the physical universe, they exist in the platonic one.

Exactly. This is a philosophical argument: are numbers fundamental to the universe or are they a construct used to describe it.

Roots of negative numbers don't exist. The correct definition of i is i^2=-1

FFS, there is no such thing as a "platonic universe". For instance, in your platonic fantasy land does $2^{\aleph_0} = \aleph_1$ ?

I'm really sick of those math retards. Meanwhile, you can give a constructive content to any of those sigils, so they do exist as computational abstractions as much as the gay furry porn videos OP likes to continuously watch on his computer screen.

I can measure an approximation of all those numbers and concepts, so it's possible that they all "exist" in a formal sense
For something to not "exist", it needs to be proven to not exist, like "a natural number between 2 and 3" by definition cannot exist without the rewriting of the proprieties of natural numbers.

1. Arrays of numbers exist.
2. Every mathematical object is simply an array of numbers.
3. Therefore every mathematical object exists.

Abstract concepts are as objectively ontologically real as whatever other thing it is you're comparing their existence to.

If I can't prove you wrong then it does in fact exist.
"Russel's teapot" isn't a real argument, it's a midwit concept (much like Russel was himself).

Easy, take a segment, call it your unit, double it and get $2$, construct an isosceles right triangle with those, the hypotenuse is $\sqrt{2}$, take the point $(0,1)$ on the plane (that you can construct), that's $\sqrt{-1}$, tangentially plop a sphere at the origin, polar opposite point is $\infty$, BOOM, done
