The old man and the king
A long time ago, there was a king in India.The king’s favourite game was chess.
One day, a wise old man came to the palace and the king challenged him to a game.“You can have any prize if you win the game,” the king promised the old man.
The old man thought for a moment and said slowly, “If I win the game, I’d like one grain of rice for the first square of the chessboard, two for the second, four for the third ... I’d like you to double the amount for each of the rest of the squares.” The king was very surprised. “Is that all ” he asked. “Wouldn’t you like gold or silver instead ”
“No, just rice,” the old man replied without hesitation.
“How many grains of rice will this be ” the king wondered, “There are 64 squares on the chessboard, so there will be one, two, four, eight, sixteen, … Perhaps a bag of rice is enough.” After thinking about it for a moment, the king agreed.
The king and the old man played the game for a long time. Finally, the old man won, so the king ordered his men to collect a bag of rice. The king’s men put one grain on the first square, two on the second, and so on. After a few squares, the king realized the problem - even with all the rice in the country, he would still not have enough rice to put on the chessboard!

A long time ago, there was an Indian king who loved chess. One day, a wise old man came to the palace, and the king challenged him to a game and promised him any prize if the old man won. The old man said he wanted rice - one grain for the first chessboard square, then double the amount for each next square. The king felt surprised and asked if he wanted gold or silver instead, but the old man refused without hesitation. The king wondered how much rice that would be. He thought a bag might be enough, so he agreed. After the old man won, the king's men started putting rice on the squares. Soon, the king realized the problem -even all the rice in his country wasn’t enough.
