Depends very much on what you mean by solve.

I hope you will excuse me using this reply to mention the arrest of Abbas
Edalat, a professor of Computer Science at Imperial College London, during
an academic function in Iran. He would be just the man to help you. His

lazy streams of rationals, in which the standard laws of arithmetic hold on
the nose.
