Challenging Math Puzzle: The Know, Don't Know Problem
(Delphi Implementation: U_KnowDontKnow2.pas  u_primes.pas)
Two integers, A and B, each between 2 and 100 inclusive, have been chosen. The product, A*B, is given to mathematician Dr. P. The sum, A+B, is given to mathematician Dr. S. They each know the range of numbers. Their conversation is as follows:

• P: "I don't have the foggiest idea what your sum is, S."
• S: "That's no news to me, P. I already knew that you didn't know. I don't know either."
• P: "Aha, NOW I know what your sum must be, S!"
• S: "And likewise P, I have figured out your product!!"

What are the numbers?

PI anyone?
