Number Wall app for iPhone and iPad

With the Number Wall app you can practice various arithmetical operations and significantly improve your mathematical skills.

The idea is to fill empty bricks in the wall so that the sum of two adjacent numbers gives the number above. You can create new number walls any time with the arithmetical operations you like. Walls then are generated randomly in different sizes and with different numbers.

Due to the great diversity of possible calculations, the Number Wall app is interesting, challenging and instructive from elementary school age up to the first years in secondary school.
