As promised, here is the 1st of 3 Checkerboard puzzles by one of our longstanding regulars, Bobo The Bear. This first problem has been around for a long time, and might be recognized by several of you. The 2nd and 3rd, however, are originals : )
How many squares, of all sizes, are there on a standard 8×8 checkerboard?
As always, answers can be entered in the comment section below. Answers to be revealed next week, thanks
