comment What is the largest negative number? Curiosity.
Well, I dont know @AsafKaragila opinion. But I think this in an interesting question. If you say that something does not exists in math, you need to prove. Asaf proved and this ended this question. This looks similar to the continum hypothesis to me, for example. But I can survive with the down votes =)

comment Is the number $-1$ prime?
Just 4 divisors on integers. This is prime. -1, -3, 1, 3 for 3, for example.

comment Statements with rare counter-examples
The best example that I know is the Gauss conjecture about two curves, that Liouville proved he was wrong. The number that proves Gauss was wrong is estimated to be ridiculously long. Some day I wrote an answer =)

This is about Srinavasa Ramanujan, no?

comment Can the golden ratio accurately be expressed in terms of e and $\pi$
Incridible. So fun, but so real. Huhu. Anyway, was a intersting question.

comment Results in graph theory proved using other areas of math, and vice versa
Looks like if you prove that a graph is hamiltonian in a polynomial time you can prove P=NP (a million dollar problem of clay institute).
