➜ EXERCISES

With Kopfnuss, you can practice basic arithmetics, the rule of three, percentage calculation, roman and square numbers and calculating basic sums of money.
Each exercise contains ten problems. Take your time solving them, theres no time limit. If you get one wrong, Kopfnuss will show you the correct answer and ask the same question later again.
Some exercises take approximations for an answer. These are identified by "≈" preceding the result. A 5% spread is perfect, a 10% spread is the permitted maximum.
You can choose the level of difficulty for all exercises. If hard is no more challenge to you, Kopfnuss will increase the level of difficulty. If your score withers, the problems get easier again.

Pros and cons of Kopfnuss app for iPhone and iPad

Kopfnuss app good for

Tolle App macht süchtig. Was noch genial wer wenn sie ins Game Center kommen würde, Highscores usw. Sonst alles Top!!!
It worths its price! probably the best of this class of applications. IT is nice and useful. It should really improved by adding more set of tests. Tests with fractions are a notable absence, from simple comparsion tests between fractions, to simple sum, simplification etc... Equivalence between different units are also useful (meters to mm and so on).
Had tons of fun already. My kids love it. Posting results on facebook works great. Ive tried a lot of math apps but this one rocks most.
A fun, friendly app to keep your mind sharp, quick and flexible. I particularly like that you can keep statistics over time.
What a great way to get ones couch potato brain of its couch with some number nut cracking! The app is beautifully executed, progressively more difficult problems are well chosen, and getting them right gives a neat sense of ackomplishment. Well done!
What a fun way to jog ones brain! I love the variety and the time trials are great. As a teacher though, my favorite thing about this app is the chalkboard design. I would highly recommend this app to anyone who is looking to exercise their brain, practice math skills (awesome for school-age kids!) and just general math geeks.
