For instance, one grain on the first square, two on the second, then four on the third one and so till the 64th square. This makes the figure of 18,446,744,073,709,551,615 on the last 64th square of the chessboard.

Wheat and Chessboard Problem Equation:

To solve this wheat and chessboard there is a proper mathematical equation. First of all the number of squares on the chessboard is calculated. The is 8×8= 64.


T_ = 1 + 2 + 4 + cdots + 2^ = sum_^ 2^i = 2^ – 1 ,

There is the derivation of the too. However, it will give the result of figure 18,446,744,073,709,551,615 .

The straightforward, animal power arrangement is simply physically twofold and includes each progression of the arrangement:

T64 = 1 + 2 + 4 + …… + 9,223,372,036,854,775,808 = 18,446,744,073,709,551,615
