Great App

This is a great app to learn practice mental math. I do wish there was an option to enter my answers instead of choosing from the given answers, but that is not why I gave four stars. There is a problem with the casting out by nines level. When both multiples add to zero, and the answer is zero as well. It is likely that the game will give you the incorrect answer. So while it is correct by the casting out standards, you will get it wrong.
