New application is a math exercises workbook in form of simple game. Exercises are designed for a bit more advanced students - around 10 years old.
Tasks are based on 4 basic calculations: addition, subtraction, multiplication and division. Most of exercises are mixture of this four. For some exercises brackets are used. There are 14 different types of tasks altogether (in free version only 6 are available). Each task has 5 difficulty levels.
We also introduced new design of application. We call it "Nineveh Design". It is inspired by one of the oldest libraries in history. Please read about Nineveh on wikipedia it is very interesting.
