I'm not a schoolchild, but sensation from school light years away. But I wanted my old cell again a little effort and practice. To me this Math app was just right.
And here may be expected, like crazy .. In each category, there's plenty here arithmetic fun. For example, addition, subtraction, multiplication, division, arithmetic, geometry, Bruchrechnen, powers, equations. Those who prefer messed up, can play "Mixed" in the categories.
Within the categories there's then sections that you play at will. If you manage a section, the next will be activated. Of course, the tasks from time to time be difficult.
For avid schoolchildren, math lovers or old hands like me who between times quite like solving one or another bill and so strain the brain cells, optimal!
