**Mathematician Andrew Beal is offering $1,000,000 to anyone who can prove or disprove his prediction.**

**Beal's Conjecture** is one of many mathematical ideas which seem very likely to be true, but which nobody has managed to prove. Beal first had the idea in 1993, but couldn't prove whether it was right or wrong. In 1997, he offered a prize of $5,000 to anybody who could either prove the conjecture or find an example that didn't fit.

Since then, the prize money has been going up steadily, but despite the cash incentive nobody has been able to prove or disprove the conjecture. Now, Beal has put the prize up to $1,000,000.

The latest increase brings the prize to the same level as the Millennium Prize Problems, seven maths problems that the Clay Mathematics Institute offered $1,000,000 for solving in 2000. So far, only one has been solved - and the mathematician who managed it turned down the prize.
