However, if you are complaining about mathematical puzzles... Some advice for those that are getting annoyed. Read the puzzles, try to figure them out. If they are trivial for you ignore them, however, I think you will find that if you actually do much programming you will find that applications for the logic required to solve these pops up all over the place.
