very good for beginners

just uploaded this app today and my son already spent about an hour playing with it. as he went through the levels even he noticed he was doing it faster. Its not easy to convience a 6 year old to sit down and do some math, so I am very happy. I agree that I would like to be able to mix in addition and subtraction (later on multiplication and division) but even with this format I think its a great app for a beginner.
