Each of these articles reports on the offer by Andrew Beal, a Dallas banker, to award a prize of US$50,000 to anyone who can solve a number theory problem he has proposed. The problem, known generally as the Beal Conjecture, bears some similarity to Fermat's Last Theorem, which had stumped mathematicians for 350 years and which was solved recently by Princeton mathematician Andrew Wiles. Fermat's Last Theorem says that the equation A^{n} + B^{n} = C^{n}, where all of the letters represent whole numbers, has no solution if n is bigger than 2. The Beal Conjecture states that if A^{x} + B^{y} = C^{z}, then A, B, and C have a common factor (here all the letters represent whole numbers, with x, y, and z bigger than 2).
