Test your math skills with my first created quiz!

I've started a general Flex/ActionScript 3 (MXML/AS3) code library in Flex Builder 3 focusing particularly on a Ruby-On-Rails/CakePHP-like MVC implementation for any kind of project and abstract, white-label game packages for simple but popular games. I would like any game suggestions but here's what I intend to make:
1) playing cards classes and rule-sets for decks, dealing and players.
2) card game algorithms and events for poker (hold em, 5/7 card stud/draw, hi/lo), blackjack, solitaire (any favorites or names?), and my favorite with friends, Egyptian Rat-Screw.
