Thank you for the feedback, I really appreciate it! I actually did implement a system to make the calculations harder but put a hard cap of 21 on all of the numbers as after that I think it gets really unmanageable. I did not make it possible to win or lose in this game so it is more of a tool than a game, but, in the future, I do want to gamify math by making the equations act like Warioware microgames. Thx for playing =D
