If you draw a nine by nine square on a piece of paper thus giving you eighty one small squares, how many squares of any size can you construct in total?
The problem is that they all appear in the latest postings as "Puzzle" so that I click on the question only to find that I've already looked at it and I would be surprised if I am the only one to find that annoying.
The title of this one could be "Puzzle - 9x9 squares" or something like that, or if you can't really think of a couple of words to summarise the puzzle then simply start numbering them 1, 2, 3 and so on (but a brief description would be so much better).
