The program has 3 levels and when you have succeeded this thenthe goal is achieved to simply calculate math.
The first level has help tools to achieve the outcome. Thesecond level hides some help tools and on the last level there areno helptools anymore. This level is a good test wether the helptools are moved from the screen to the mind!
There is also a counter for the number of good and wronganswers. You can only go to the next math when the answer iscorrect. So the student discovers himself which errors he makesagain and again.
Good luck with it!
