eTwinning project

One of the popular myths of chess was that it was invented by one person, the Brahmin, Sissa, who invented the game to teach his king that he could not win without the help of his subjects. When the king asked Sissa what reward he wanted for such a fine game, Sissa replied that he wanted one grain of wheat for the first square of the board, two for the second, four for the third and so on to the 64th square.

The last number is 9,223,372,036,854,775,808 grains!
