Inheritance A billionaire, let's call him Gil Bates, decides to leave a portion of his fortune to his 7 children, and the rest to charity. He places the money for his children in a large chest. When he dies, the first child says, "My siblings are all crooks; I'm the only honest one," and takes 1/7 of the money in the chest. Any part left over is given to the nanny. (That is, any part beyond the 7 equal shares.) Then the second child does exactly the same thing, taking 1/7 of the remaining money, and giving any leftover portion to the nanny. All 7 children do this, each taking 1/7 of the remaining money in the chest (even dollars, no change) and giving the balance to the nanny. The nanny gets a different amount from each child. How much does the nanny get altogether?

He doesn't think that knowing a lot of mathematics is a prerequisite for having fun with mathematics. He has an amazing ability to translate complex mathematical ideas into puzzles or games.
