How many squares are there on a chess board? The board has 8 squares along the bottom and 8 squares up the side, so most people would say the answer is 8x8 =64.
The problem may be solved using simple addition. With 64 squares on a chessboard, if the number of grains doubles on successive squares, then the sum of grains on all 64 squares is: 1 + 2 + 4 + 8 + ... and so forth for the 64 squares. The total number of grains equals 18,446,744,073,709,551,615 (the 64th Mersenne number), much higher than what most intuitively expect.
