Cool! Nice program, it works without the pause that BASIC programs which do the same thing have. This means it's really hard to notice, at least until you do 521x34 and you get 28 as an answer...
Which brings me to the one major improvement that this program needs: a feature that puts your fake answers in the correct order of magnitude. I imagine this can't be too hard, especially since you've gone this far, writing a flash program and all. If you could make it give out plausible, but wrong, answers, it would be much better. Overall, keep up the good work.
