Needs more levels

My 3rd grader likes the game, especially the music and the sound effects. However, there are only 7 levels for addition and 5 for multiplication and these are too simple. The only increase in difficulty is achieved by adding one or two zeros at the end of the target numbers. For example, in the first level of multiplication the goal may be finding 2 numbers with product 42. In level five, the goal would be a product of 4200. The addition levels are on the same principle, the hardest problems being of the type "83 plus what gives 89".
