Who will be interested in this video?
First of all, to schoolchildren who want to pass an exam or test in mathematics with flying colors. To all who simply love mathematics. And also to all those who realized that they have certain problems with some topics, but still decided not to give up, but to "fight" to the bitter end. Go for it! I will try to help you. In my videos, I will consider all the most important topics in mathematics from grades 5 to 11,
In addition, we will analyze the OGE, analyze the Unified State Exam and analyze the Centralized Testing for different years.
Dedicated to all who will take an exam in mathematics, those who are preparing for the Centralized Testing, Unified State Exam, OGE...

Why do we need mathematics at all?
1. Mathematics develops thinking.
By studying mathematics and solving problems, we learn to generalize and highlight the important, analyze and systematize, find patterns and establish cause-and-effect relationships, reason and draw conclusions, think logically, strategically and abstractly.
Just as regular sports training “pumps up” the body, makes it healthy, strong and resilient, so regular math classes “pump up” the brain - develop intelligence and cognitive abilities, expand horizons.
2. Math classes train memory.
Scientists from Stanford University in the USA studied the process of human solving mathematical problems and found out that adults use thinking for these purposes and the skill, brought to automatism, of “retrieving” answers from memory that are already there.
3. Mathematics strengthens character.
To correctly solve mathematical and logical problems, you need attentiveness, persistence, responsibility, accuracy and precision. The more regularly these “character muscles” are trained, the stronger they become, the more often they help the child in solving not only academic problems, but also life problems.
4. Music for mathematics, mathematics for music
A comprehensive study conducted by Barbara H. Helmrich from the College of Notre Dame in Baltimore found that children who played musical instruments in middle school significantly did better in mathematics in high school.
5. Mathematics helps to succeed in the humanities.
Mathematics is an interdisciplinary science, it is closely related to physics, geography, geology, chemistry. Sociology and economics are inseparable from mathematics, and many conclusions even of the usual humanities, such as linguistics, journalism, are based on mathematical models and concepts, mathematical and logical laws.
6. Mathematics develops skills in solving everyday problems.
The more complex the math problems become, the more skills are required to solve them. Thanks to mathematics, we get rid of bad habits:
we don’t guess, but use only precise terms;
we don’t just mechanically memorize information and rules, but evaluate them;
we analyze, reflect in order to understand and learn new material, a new life lesson.
7. Mathematics is the basis of a successful career.
If 10-15 years ago, learning foreign languages was considered promising, now you won’t surprise anyone with fluency in several languages. Now, professional demand largely depends on understanding technologies, the ability to think, abstract, and the ability to solve non-standard problems. It is extremely difficult for those who want to work in the IT field to do without knowledge of mathematics.
8. Solving problems develops psychological fortitude.
Solving math problems helps improve your emotional background. It can relieve anxiety, helps control emotions, and prevent stress.
These are, of course, not all the reasons why one should study mathematics and other sciences in general. Science is an integral part of the development and activity of any person, just like friendship, family, sports, health, work, and so on.
