Hi there :) I come up with some interesting math puzzles and riddles. A word of advice before you start solving these puzzles. If you really get stuck,  don't give up or you'll spoil the fun. Put the sticky puzzle  aside, o r you can try to solve an easier puzzle similar  to the sticky one. Or just guess trial answers just to  see if they make sense. Who knows, you might be lucky and hit  on the right answer. Of course, fluke answers will not be satisfying than  working out the puzzle logically. You need not worry about the correct answer. You will find answers right below the puzzle. But i suggest you to look up the answer as the last resort.  This may give you the clue you  need without giving the game away. As you will see, I have written  very complete answers to the harder puzzles or to those  needing several steps to solve.  But trust me most of the puzzles call for straightforward arithmetic or  simple reason...
