+51 So here is the problem.
How many squares are on a standard (8 x 8) checkerboard?
A word of caution when introducing this task: Often this is seen as somewhat trivial, counting just the 64 small squares; some go an extra step and realize that the whole board is also a square, for a total of 65. Do recognize that the board also has 2 x 2 squares, 3 x 3 squares, and so on.
So I found the answer to this but there is also an equation to this too. The equation is (n(n+1)(2n+1))/6 however I have no idea how to get that and how it works. Can someone explain how they got the equation?
