A Dumb Mistake!

If I asked you how many squares are on a chess board? You would say 64 you are wrong!

It is 204squares! How? Because it if you thought harder you would see a big square inside this square 4 squares then there is 9 squares then 16 squares then 25 squares then 36 squares then 49 squares then 64. Here is how I know:
