Benefit
Surely, you may wonder, for what reason among the exercises collected so many tasks related to numbers. I tried to collect techniques that cover all areas of brain activity.
From conversations with familiar philologists, who seemed so far from the exact sciences, I concluded, that the language system and mathematics are very closely related. Language and numeric coding have a clear logical structure; they form a system with clear system connections. With logical thinking, you can acquire the skill of information processing at the highest level.
In Japanese culture, there is such a thing as "mental arithmetic." It focuses on performing numerical operations (including multiplication and division) using the oral counting method. This practice allows students from school to train the right hemisphere and develop its unlimited possibilities. For those who do not like math, I advise you to treat this exercise as a way to use those areas of the brain that contribute to the study of speed reading – attentiveness, concentration, analysis. Gradually, the numbers will no longer appear to you as “strangers,” which, even at the level of everyday life, will improve the skills of perceiving digital information.
Description
You are offered mathematical problems which you should solve as correctly as possible in a limited time. You can choose the optimal level of difficulty, trying to move from easier tasks to the most difficult ones.
