I made a computer program for teaching you how to solve simultaneous/quadratic equations a while back. It generates a random question for you, at a desired difficulty, and then you try and answer it. If you get it wrong, it gives you a walk through of the correct method. I was originally going to try and turn it into an app or something to try and sell, but hit a ceiling and lack of energy put it on hold. I got the code all sorted, just was at a loss putting it on an actual platform besides a text screen. Maybe one day.
