A Texas Banker named Andy Beal just upped his reward to One Million Dollars for anyone who can solve a complicated math equation.
His original offer was $5,000 in 1997 and every year the problem goes unsolved the reward goes up.
Here is a link to the problem, the rules and the place where you can claim your cash.
If you solve this all I ask is 50 grand or so for turning you on to the challenge. Actually I would just settle for a couple hours math tutoring instead. I could use some refreshing in Algebra so I can help my daughter with her homework.
