"Everyone has studied mathematics, and I once asked a few classmates, and the answer was the same: mathematics is learning to calculate and calculate. In fact, everyone is wrong, and I can tell you with certainty that mathematics is the mother of natural science, and without mathematics, or if you don't learn mathematics well, you won't be able to learn every subject of natural science. At the beginning, Zhou Fugui was amazing.

"Do you know Einstein? If you know, please raise your hand. Zhou Fugui then asked. Seeing that no one responded, he slowly swept his gaze to Tang Boqiang, Tang Boqiang's heart was excited, knowing that there was no way to hide, so he raised his hand and stood up and said: "I know a little, I saw it from a book, saying that he was a great physicist and the inventor of the theory of relativity. ”

"Excellent! Please sit down. Zhou Fugui said happily.

"Yes, Einstein was a physicist, and he was a great theoretical physicist, the so-called theoretical physicist, simply put, is to think and reason about physics through all kinds of knowledge that he has learned, especially physical knowledge, and use mathematical methods to prove whether the reasoning is correct or not through very complex mathematical operations, and this is how Einstein's theory of relativity was born. On the other hand, Einstein was also a great mathematician. ”

"Only by learning mathematics, the mother of natural science, can you continue to swim in the ocean of natural science." Zhou Fugui further elaborated on the importance of mathematics.

After that, he wrote a few math problems on the blackboard, these are simple math problems, according to usual, everyone will solve such math problems, but after Zhou Fugui wrote these problems, he showed a rare smile and said: "These problems are estimated to be done by everyone, because they are all simple calculations, I ask everyone the answers, and I want to give them immediately." ”

As a result, the whole class stays there. Yes, everyone knows such a question, but it seems impossible for everyone to give an answer to the calculation of such a long string of numbers immediately.

I saw Zhou Fugui make some adjustments to the numbers and the symbols of addition, subtraction, multiplication and division of each question as if he was doing a trick, and the answer came out immediately.

But the students didn't seem to sell it, thinking that the teacher must have prepared the lesson in advance, and it must have been done quickly. Zhou Fugui is so smart and how rich his teaching experience is, he quickly saw the doubts of the students.

"Now please ask Tang Boqiang to come up and write a question similar to the previous few questions on the blackboard, and I will give the answer immediately." Zhou Fugui named Tang Boqiang.

It's Tang Boqiang again, it seems that Tang Boqiang has made too deep an impression on the teachers in school.

Tang Boqiang stood up and walked quickly to the podium, and wrote on the blackboard with chalk according to the pattern of the question just now. Tang Boqiang's interest in mathematics has never been very strong, usually just study and complete homework step by step, standing on the podium, he can't write many "problems" in a hurry, I saw Tang Boqiang just finished writing the equal sign, Zhou Fugui immediately wrote the answer.

The student asks the question, and the teacher immediately writes the answer. The questions were written quickly, the answers were written faster, and the classroom was silent, and everyone watched this scene quietly, and almost everyone opened their mouths to show a look of surprise. The calculation is too fast!

"Good! Stop it. Zhou Fugui stopped Tang Boqiang and asked Tang Boqiang to return to his seat.

On the podium just now, Tang Boqiang had been conquered by Mr. Zhou's speed, and he couldn't come back to his senses when he returned to his seat, and Mr. Zhou had already begun to explain. When Mr. Zhou explained the calculation method, the students suddenly realized: it turns out that there can be so many calculation methods, so fast.

"When you master the methods and skills, you don't need to write them at all, as long as others say it, you can use the method of 'mental arithmetic' to quickly give the answer, and this method will definitely be used in your life and work in the future." Zhou Fugui explained.

"Mathematics is so magical, it can make great scientists, and it can also serve all aspects of people's lives, learn mathematics well, and benefit for life!" Zhou Fugui continued to emphasize.

The first day of class in the first semester of the fourth grade had a strong impact on Tang Boqiang, who was only in his early tens. Although young, but perhaps the children of the poor are in charge of the family early, Tang Boqiang began to carefully observe the changes in the surrounding environment and think about how to learn more skills, including kung fu, influenced by his father, Tang Boqiang always believed that knowledge is the only way to change the fate of the future.

Bajiao Town is located on the border of China, and belongs to the far away place of the Emperor of the High Mountain. When the wind of ** blew to Octagon Town, the wind was nearing its end. But even if this wind is nearing the end, from the officials to the people, they dare not slack off. In his spare time, he organized and studied various documents and instructions, and often returned to school in the evening for mobilization meetings.

One morning, after the Chinese class, before the end of class, Guan Pingfan said: "According to the spirit of the superiors, we want to assign an assignment to everyone, that is, to write an article about the relationship between teachers and students, and the town is going to hold a town-wide meeting. Everyone can hear that Mr. Guan is extremely reluctant to say this, which is related to his dissatisfaction with some of the practices in the *****.

After non-stop meetings, Tang Boqiang probably knew the current situation. From the town leaders to the school leaders, the views on teachers are roughly divided into two factions, one group advocates that teachers should be included in the target of criticism, and teachers are stinky old nine; One faction thinks that teachers are not at fault, they all strictly follow the requirements of the state to educate teachers, Bajiao Town needs such teachers, and the country also needs such teachers. Tang Boqiang certainly supports the latter view.

The article must be completed on time. According to Tang Boqiang's stubborn character, he must write according to his own point of view. But which angle to start from did make Tang Boqiang feel very difficult.

At that time, Tang Boqiang was already suffering from "reading obsessive-compulsive disorder". Because he couldn't find more books to read, and his family didn't have the conditions to subscribe to newspapers, so only when he saw a paper with words, Tang Boqiang couldn't help but look at it, even if he saw such a paper on the ground on the road, he had to squat down and read it before leaving, so that the information obtained from sporadic reading entered Tang Boqiang's brain with a strong memory, and slowly summarized into a piece of information. Now, this information has been extremely useful in writing this article.

Tang Boqiang has made up his mind and is determined to write an essay with a good relationship between teachers and students. When I was in the self-study class in the afternoon, everyone else was playing or reading a book, and Tang Boqiang was quietly conceiving this composition, and in the last class, he picked up the pen and wrote. Before school, an article entitled "Teachers and Students Are Comrades in the Same Trench" was completed, revised and then neatly copied on the text, and handed over to Teacher Guan before leaving school.
