How to play

Training math with Mathe-Kaiser is easy as 1-2-3: a problem (above) and an answer (below) is shown.

Now you have a few seconds to decide, whether the answer is correct - if so, simply tap it, otherwise cross it through

correct incorrect

Don't forget: time is of the essence and every mistake reduces your life span...


Understanding fractions is an elementary step on the way towards algebra. Mathe-Kaiser allows you to get graphically acquainted with simple fractions (pizza-style).

Learning the clock

Mathe-Kaiser makes learning to tell the time a breeze. In three different levels you can start with full hours, advance to half and quarters and finally to random time stamps.

Combining the Basics

Check whether you've got a solid grasp of the basics with the more complex exercises. Here often there are multiple ways to get the result, for example by switching the elemets when adding and subtracting. Finding the smart way saves time (and life)...

Direct Feedback

Mathe-Kaiser comments every input you give. At the end of the game you see a list of all questions that you answered incorrectly or not at all.

Too easy?

Exercises like Addition, Subtraction, Multiplication or Division are split into different levels of difficulty. While level 1 allows kids in 1st or 2nd grade to get acquainted without getting frustrated, things get much tougher in levels III (or in some cases even IV). Here many (untrained) parents will quickly face the limitations of their current level of "computing power" (and concentration).
