Mathematics: mental arithmetic

A universal system for developing of mental counting will allow you to keep your brain in good shape. Remember: the brain, like your whole body, requires care, including training. Daily several minutes exercises will not only allow you to better cope with "household arithmetic", but also positively affect the effectiveness of the thinking process in general.

The application is completely free, there are several levels of difficulty for each of the operations in the simulator:

- Addition

- Subtraction

- Multiplication

- Division

- Squaring

You can also set the duration of the round in minutes or tasks.

All your achievements are saved, you can always look at your previous results (up to the time spent on a specific task) and analyse your development.

The simulator is suitable for both students and adults. The application will help in preparing for exams - exam in mathematics especially. For those who decided to connect their lives with chemistry, physics, computer science or economics, the ability to count quickly will also be extremely useful.

Personal observation: among other skills, it seems to help train mindfulness.

A couple of tips:

- if you come across a difficult task, do not rush to bruteforce all the possible options, try calmly, bit by bit, solve it, do not rely on luck, do not chase time.

- the switching-on of squares (especially the second level of complexity) with the multiplication and division enabled allows you to get extremely complex tasks.

Please report all shortcomings and suggestions in the comments to the application.

I wish you a enjoyable and effective workout! :)
