After four years as a class representative, senior high school entrance examination mathematics 150: What details are indispensable for learning mathematics well? For math lovers, this is also the jewel in the crown of science and rationality, but for students who have never been able to get started, math class is a nightmare on their own learning road, and even how to qualify has become their highest goal. For advanced learning and training, talent is very important, but for beginners, methods and perseverance are the key factors to measure the moral bottom line of exam results, so there is still a chance to improve your grades if you don't pass the exam.

I have been a math class representative for four years since grade one. Finally, in the case of the senior high school entrance examination, I got a perfect score of 150 in mathematics and entered the core rocket class as I wished. In the learning process of junior high school students, Zeng's math performance has been particularly excellent, but he has his own experience and views on how to learn math well. Zeng Yanshun thinks that mathematics is a subject that pays great attention to details, so if you want to improve your mathematics performance, you can't miss three key points.

1 and the learning idea of equivalent substitution

It has been clearly pointed out that in middle school, mathematics is more difficult. For many students, the main reason why they often fail to get high marks is that they have not got rid of the single mathematical thought in the basic education stage. When you encounter a complex problem, you always want to get the answer immediately according to the original standard value, but in many ingenious problems, "equivalent replacement" is the key problem-solving idea.

Zeng Yan Shun gave a simple example. For example, A is twice as much as B, so in the case of doing the problem, A is indeed replaced by 2b, but A is still the main parameter for answering the question. This logical thinking of equivalent substitution is very common in mathematical problems. A problem that puzzles people in solving problems is likely to have different design inspiration by changing a main parameter and standard value.

2. The learning method of reverse reasoning.

It used to be thought that math classes often made people feel complicated. On the one hand, pay attention to logic, that is, you will not answer inexplicably. On the other hand, when proper problem-solving skills cannot be used to solve problems, the data and its scores will be the most impressive.

Zeng Yan Shun thinks that it is necessary to think logically in the opposite direction if we want to improve our math scores. It is also a kind of reverse reasoning that many old classmates get together to calculate the answers in the exam, but they should cultivate their reading habits in the usual learning process.

3. Logical thinking of constructing the framework.

Mathematics is a subject that can't just learn a chapter and a catalogue. For example, the four operations are the basis for measuring all the test questions, so doing a good job in the overall framework construction is an important guarantee for improving math scores.

The content of mathematics is chaotic, but it is closely related to each other. Learning how to connect these knowledge points and build a knowledge structure map is the main step.
