The Master Mental Math App
Good mental arithmetic is a matter of practice and simply brings advantages.
01
Our database
With over 3000 exercises ranging from simple addition/subtraction and multiplication tables to three- and four-digit mental arithmetic problems in the basic arithmetic operations, the database covers simple math tasks for students from grade 1 to high school and various difficulty levels for adults.
03
Motivation through medals
In the Master Mental Math App, there are 7 learning levels, and for each completed level, there is a medal. Each learning level typically consists of 18 lessons with approximately 450 exercises.
02
Short writing lists
In order for the brain to get used to mental arithmetic tasks, it should be trained for 10 minutes daily. The short exercise lists are designed for efficient learning. Training one to two mental arithmetic lists daily can be easily scheduled and can become part of your routine.
04
Playful, visual and auditory learning
The Master Mental Math App supports playful, visual, and auditory learning at your own pace. Learning goals can be set by the user. Depending on the level, mental arithmetic in the basic operations becomes more challenging.
05
Personalized exercise lists
The incorrect tasks are listed in the personalized learning list. Using an algorithm, the mistakes are repeated in new exercise lists. Through training and the short exercise lists, learning success occurs from the very beginning. The exercise list is accessible at any time.
06
A wonderful learning experience
The tasks can either be displayed or read aloud. Doing mental arithmetic without seeing the task is significantly more challenging. The tasks are not generated randomly but are compiled based on abilities and arithmetic operations. To help the brain get accustomed to mental arithmetic, it is recommended to train for 10 minutes daily. The short calculation lists are designed for efficient learning.
