These puzzles are replaced on a regular basis and their solutions are given when they are replaced and archived. If you value learning, how you think about them is more important than their solutions. Some of them are applications of the math that is taught in school at various grade levels. Some may require very little in the way of math skills; they may instead require thinking that is logical, methodical or creative. Some may be too easy for you, because they are designed for students who have not reached your level of skill development; others may be too challenging, for the opposite reason. But if, like Goldilocks, you try them all, you’ll find that some are just right. Solutions, comments and questions are welcome.
