Instead he only had one request: He asked just for a few grains of rice in the following manner: the sultan was to put a single grain of rice on the first chess square, two grains on the second square, four on the third square and carry on doubling this number on every consequent square to fill up all 64 squares of the chessboard.

This seemed to the ruler to be a modest request, so he called for his servants to bring the rice. Did the Sultan manage to fulfil the wise man’s request?
