Neuropsychologists proved the best way to develop the brain - solving simple tasks for the time.
In this book you will find more than 50 puzzles in which one extra one needs to find one extra.
You need to solve problems for a while: for the simplest at the beginning of the book, 30 seconds are given, and for the most difficult closer to the end - about 5 minutes.
This book is addressed to both children and adults - everyone who is interested in development Memory and thinking.
- Exercises for logic,
- exercises for the development of computational abilities,
- exercises for memory training,
- exercises for the development of spatial thinking,
-- Particular training.
Having trained on these simple tasks, your brain will learn to quickly process information and, for example, examples in mathematics will be given to you faster. To the complex ” - perform them in order.
It is given a limited time to perform exercises - it is recorded next to each task. Set the time and write down your result.
Through a few pages you will meet a similar task - note how much easier you will do it!
You should not be upset if you suddenly come into a dead end or did not meet the time. Just go to another task, and come back to this later. Next time you will look at him from a different angle, and the decision will be found by itself.
