MathInvaders app for iPhone and iPad

Discover a funny way to learn multiplication tables.
Each invader shows an operation, the user has to enter the result to make it explode.
No need for documentation, you immediately understand how to play.
My children love it! I can test them just letting them play and hearing the sound effects. There is also a high scores table.
At the end of the game, the program shows the missed operations.
There are several levels with invaders coming faster and faster.
You can change the operations and the maximum table number in the general settings (addition, soustraction, division, square, ..). But do not tell it to your children !
