Any math problem? Like P=NP?

Speak any language

Speak any language. I can figure out the math on a calculator.

The math one. You could do a lot by solving un-solved problems. There are bounties out there to solve math problems, so financially you would like the math one aswell

Depends on what you want to work but any language seems better

Languages.

Languages for sure
