Then you, or Clark, should explain why Hulk is not taught in all primary school on he planet, like elementary arithmetic is. May be we should ask all physicists, economist and bankers as well, to use Hulk instead of the numbers, when they share their results. Do you agree that x^3 + y^3 + z^3 = 33 does admit or not a solution? Do the term “open problem” makes sense? Ca you give me an open problem about Hulk?
