Learning method reference:
First, consciously train yourself to concentrate.
When you are doing your homework, don't do anything else or think about anything else. You won't jump directly to the next question. Don't be distracted. Gradually increase the difficulty, and finally insist on not giving up halfway or thinking about other things, especially playing mobile phones, before the math homework is completed.
Second, create a good learning environment.
Try to keep quiet when you do your homework. Don't put anything on the table except books and school supplies, so as not to distract you. Don't be disturbed by the environment, be more motivated.
Third, learn to summarize.
If you can quickly understand the knowledge points needed for this problem after reading it, then the speed of solving the problem will be improved. In addition, after solving the problem, we should also sum up our thinking. The coverage of mathematics knowledge in middle schools is not wide. After summing up, you will find that many topics have their own rules to follow, and you can easily encounter similar problems in the future.
Fourth, proper practice.
Everyone knows that the most important thing in learning mathematics is practice. Usually, doing more basic questions can improve the proficiency of solving problems, and doing more intermediate questions can familiarize you with exam questions. You are not advised to do more difficult questions. You can try to judge the difficulty and master the problem-solving skills. Don't be blind and don't get into trouble.
Learn to summarize when doing questions, and summarize which questions often appear, which may be the questions of the senior high school entrance examination. Some students are doing problems every day, but they have not improved by using a lot of tutorial books. This is doing the problem blindly, without skill and summary.
Students pay more attention to problem-solving ideas, methods and skills. It is very important to master the problem-solving ideas and summarize the problem-solving skills. Time is the most precious in the exam. Mastering good ideas, methods and skills can not only solve problems quickly, but also make mistakes easily.
A brief history of western mathematics;
The evolution of mathematics can be regarded as the continuous development of abstraction or the extension of subject matter, and the eastern and western cultures have also taken different angles. European civilization developed geometry, and China developed arithmetic. The first abstract concept is probably number (China's arithmetic), and its cognition that two apples and two oranges have something in common is a great breakthrough in human thought.
Besides knowing how to calculate the number of actual objects, prehistoric humans also knew how to calculate the number of abstract concepts, such as time-date, season and year. Arithmetic (addition, subtraction, multiplication and division) will naturally occur.
In addition, you need writing or other systems that can record numbers, such as Mu Fu or chips used by the Incas. There are many different counting systems in history.
In ancient times, the main principles in mathematics were the study of astronomy, the rational distribution of land and grain, taxation and trade. Mathematics is formed to understand the relationship between numbers, measure land and predict astronomical events. These needs can be simply summarized as the study of quantity, structure, space and time in mathematics.
After the Renaissance in Western Europe from ancient Greece to16th century, elementary mathematics, such as elementary algebra and elementary trigonometry, has been basically complete, but the concept of limit has not yet appeared.
/kloc-the emergence of the concept of European variables in the 0/7th century made people begin to study the relationship between the quantity of change and the mutual transformation between graphs. In the process of establishing classical mechanics, the method of combining calculus with geometric accuracy was invented. With the further development of natural science and technology, the fields of set theory, mathematical logic and so on, which are produced for studying the basis of mathematics, have also begun to develop slowly.
