A billionaire is offering a $1 million (R10 million) prize to anyone who can solve a maths problem.
Andrew Beal, a Dallas financier, is so desperate for someone to figure out his namesake equation, the Beal Conjecture number theory problem ?which has cast a shadow over mathematics since the 1980s ? he’s put up the huge reward.
The American Mathematical Society confirmed it will award the $1 million in exchange for the publication of the answer to the conundrum.
It's not the first time Andrew has offered a prize to someone who can solve the mystery. In 1997, he was prepared to give $5,000 (then R22 500) to anyone who could work it out and the prize has grown substantially over the years.
