Two whole numbers, m and n, have been chosen. Both are unequal to 1 and the sum of them is less than 100. The product, m × n, is given to mathematician X. The sum, m + n, is given to mathematician Y. Then both mathematicians have the following conversation: X: "I have no idea what your sum is, Y." Y: "That's no news to me, X. I already knew you didn't know that." X: "Ahah! Now I know what your sum must be, Y!" Y: "And now I also know what your product is, X!" The Question: What are the smallest values of m and n?
