App Description

Tien is a fun APP which helps to easily learn and train your mind in doing calculations. Using a star based leveling, you can tune the difficulty to the right level for you. It is fun to perform mental arithmetics. On the first levels only adding and subtractions sums are given. On the higher levels you will also be challenged with multiply and divide sums. To make it even harder you can even set a timer.

To learn from your mistakes your answers will be analyzed. The correct answer and, when needed, also the given wrong answer will be displayed. You probably won't make a mistake twice.

The sums are grouped in to tests. After finishing one test, a summary is given. Trophies can be earned and collected, which are stored in your own trophy cabinet.

Try it, it is fun and awesome!
