This is the latest update to the original cross multiplication application released a few weeks ago -- original posting here

Version 1.1 of the app allowed me to practice with threading as well as state.  The app has an interactive timer which is not intrusive by starting/stopping automatically.  Your best error-free scores are saved so you can challenge yourself to beat it over and over.
