Mental arithmetic pure, no frills, without annoying ads!

Anyone who has mastered the basics and can add and subtract numbers up to a hundred in their head will have a clear head in math lessons and can concentrate on the essentials.

Just 5 to 10 minutes of practice a day, like waiting for the bus or a date, will make you (and your math grades) better.

The arithmetic trainer supports mental arithmetic on almost every level:

You can

- set the number range from 20 to 999,999,

- practice the basic arithmetic operations individually or mixed,

- double or halve,

- practice square numbers, cube numbers or other powers,

- Practice rows one at a time and

- choose whether negative numbers should also appear in the tasks.

A simple evaluation is carried out at the end of each series of tasks.
