"King of mathematics" hardly needs space, offers the choice of a variety of languages and calls virtually no rights, exemplary!
The covered spectrum of mathematics goes beyond the basic arithmetic, geometry, Bruchrechnen through to statistics. Within the sections, there are then a plurality of tasks. Everything is designed and varied accompanied by music. The more tasks and sections to solve correctly, the more points you get and rises from a simple farmer commencing on in higher ranks.
This is a great app to playfully deal with mathematics and refresh his math skills. The game is motivating and fun. So I imagine a meaningful app for children.
