In a famous story, a wise man in India requests a reward promised by his king. The wise man shows the king a chessboard having 6
4 squares. "Put 1 grain of rice on the 1st square, 2 grains on the 2nd square, 4 on the 3rd square, 8 on the 4th square, and so on. That will be my reward." The king readily agrees and is ruined because the total number of rice grains turns out to be about 37 trillion trillion trillion grains of rice - much more than the value of the entire kingdom. How many grains of rice go in the 14th square?
