Problem -1?
After solving 115 questions, the website said that I've unlocked a bonus question, problem -1, which I don't think is solvable? Does anybody know if there's some deeper lore (for lack of a better word) behind it, or is it just a quick joke?

Re: Problem -1?
I don't understand it. Either the answer is infinity, or it's a joke, and it's not infinity.
