God of black technology

After packing up his things, under the leadership of Teacher Tian, ​​Teacher Chen came to Director Xu's office again with trepidation.Seeing Director Xu looking at him helplessly, Teacher Chen understood that things would not be so simple.

Sitting on the chair, Director Xu sighed and said, "Mr. Chen, it's really not that I don't help you, but that there is nothing I can do." When he said this, he turned his head and looked at the vigorous teacher Tian and said, "Mr. Tian, ​​please tell Mr. Chen about this matter."

Teacher Tian is a middle-aged woman in her 30s who looks very capable.She looked at Teacher Chen, and her face became kind all of a sudden, "Mr. Chen, you are also the math teacher in our class. I just said it directly without seeing anyone else. Yuan Chengde and Wang Yun's grades are very good, and you also You know, if these two students stay in the ordinary class, their knowledge will not be as profound as the students in the key class."

"Huh?" Teacher Chen frowned, "It's useless for you to ask me about this matter."

"They are almost full. Some things, I think they can actually decide by themselves. Teacher Tian, ​​what do you think?" Teacher Chen directly threw the question to the two students, "If they agree, then I definitely have no objection But if the two students disagree, then Teacher Tian, ​​you can’t force it, right?”

Teacher Tian nodded, "Mr. Chen, I think what you said is very reasonable. He is going to be an adult, but they are still studying in school after all, aren't they? And, as I have already said, key classes are more beneficial their growth."

"So?" Mr. Chen glanced at Mr. Tian, ​​feeling a little confrontational.

Director Xu coughed lightly, "I said, the two teachers are old teachers in our school, don't need to do this, don't need to do this." He paused, and then continued, "How about this, Yuan Chengde and Wang Yun , anyone can be transferred to class ten."

Looking at Director Xu, Teacher Chen can be sure that this matter is no longer what he said.It's even possible that Director Xu can't help it.

Probably the headmaster had spoken in person.

Teacher Tian said with a smile, "I won't compete with Teacher Chen for the first grade. I think Wang Yun is not bad. Or let him transfer to Class Ten. I think Wang Yun's grades have improved." spatial."

Director Xu looked at Teacher Chen and asked, "Mr. Chen, what do you think?"

Teacher Chen shook his head, "What can I think, since you have already made up your mind, why ask my opinion? Is my opinion still important?"

Director Xu smiled awkwardly, "That's not what I said, Mr. Chen, look."

Teacher Chen glanced at Director Xu, and Director Xu also understood that Teacher Chen's mood might not be too good.He coughed and continued, "There is at least one Yuan Chengde in your class who is sure to be the first in grade."

Smiled, Teacher Chen was not talking.Director Xu thought for a while and said, "How about this, let Wang Yun go to class ten during self-study tonight, Mr. Chen, what do you think?"

"I'm sorry, Wang Yun asked for leave tonight, and probably won't be able to go to class ten."

"Then let's do it tomorrow morning, just to let Wang Yun feel the difference between the morning reading of the key class and the morning reading of the ordinary class."

After discussing for a while, Teacher Chen and Teacher Tian left the director's office together.

Walking out of the office, Teacher Chen looked at Teacher Tian and said in a low voice, "Mr. Tian, ​​I don't think you are doing this properly. Why don't you discuss such an important matter with me?"

Teacher Tian also laughed, "Mr. Chen, do you think it's still possible after I discuss it with you?"

"..." Teacher Chen snorted coldly and walked up to the teaching building first, Teacher Tian shook his head and followed closely behind Teacher Chen.

After school in the afternoon, Wang Yun packed up his things and prepared to return books in the library.

Yuan Chengde glanced at Wang Yun and asked curiously, "Aren't you going to the Olympiad training class tonight?"

"En." Wang Yun nodded, "I'm going to the library to return books tonight, and I'm going to borrow some other books to read at home." When he said this, he smiled at Yuan Chengde, "Have you Interested in going together?"

"What book are you going to borrow?"

"Advanced Mathematics and Analytic Geometry." Wang Yun thought for a while, and estimated that he could only start with these two books this month.

"Very good." Yuan Chengde's eyes were shining brightly, "I didn't expect that you have already started reading these two books."

Wang Yun smiled a little embarrassedly, looked at Yuan Chengde and asked again, "Do you want to go together?"

Yuan Chengde shook his head, "I'm reading these two books, or..." His eyes rolled, "Let's compare, who can finish these two books first?"

"Okay." Wang Yun laughed, "Then we can make a deal."

Yuan Chengde looked at Wang Yun and nodded inwardly.For many years, it seems that since elementary school, he has never met an opponent.This time, I am afraid that he will really be able to meet an evenly matched opponent.He had a feeling of excitement, even blood boiling.

A good opponent can make oneself stronger faster.

Since Yuan Chengde did not go to the library with Wang Yun, Wang Yun had no choice but to go to the library alone.Walking out of the school gate, Wang Yun went directly to the bus stop.There is no need to go to evening self-study tonight, so when I get home, I will naturally continue to study the advanced mathematics and analytic geometry I borrowed.

When the bus wobbled to the stop, Wang Yun almost fell asleep.After getting out of the car, he took a breath of fresh air.Only then did he walk into the library, and the librarian was still the same librarian.When he saw Wang Yun walking in, he remembered that it was the student who came to borrow books last week.

He waved at him, and there were very few people in the library at this time.His voice was still very soft, "How about it, have you finished studying all the high school math textbooks?"

"Almost." Wang Yun said as he took out all these textbooks from his schoolbag and put them on the counter.

The librarian looked at Wang Yun and continued to ask, "What book do you want to borrow this time?"

"Advanced mathematics and analytic geometry." He said it almost without thinking.

The administrator nodded, and picked up the book that Wang Yun returned, "Then wait, I'll get it for you right away."

Wang Yun didn't have to wait too long. After a while, the administrator brought over both advanced mathematics and analytic geometry.He put the two books on the counter, took out the registration form and said, "It's still the same, after you fill out the registration form, you can take the books away."

"Thank you." Wang Yun filled out the form and put the book in his schoolbag.He took out his mobile phone and just checked the time. At this time, it seemed that the class had not started yet.

It's better to go to the class first, although he knows a little about the Olympiad in Yuan Chengde's home.But I don't know much about it, so I still need to go to the classroom and listen to the lectures.

Thinking of this, Wang Yun stood at the bus stop waiting to go back to school.

Fortunately, he didn't have time to tell his mother about not going to study at night.After the bus arrived at the station, Wang Yun walked into the carriage and found that there were not many people in the empty carriage.So, he sat in the carriage and looked out the window at the scenery.After thinking for a while, I took out the book on advanced mathematics, opened it and began to read it.

And at this time, I don't know how many people @ him on the Internet.

They were all ridiculing Wang Yun, and Wang Yun didn't know it yet.But even if he knew, he wouldn't care.If he cared about everything, wouldn't he...be mad at death if he didn't live to be old.What's more, what he needs now is not enthusiasm, but knowledge.

When the bus stopped at the gate of No. [-] Middle School, Wang Yun checked the time, and the class had already started.

Walking into the campus, he carefully recalled the location of the Mathematical Olympiad training class. After searching for a while, he finally found the location of the training class.When I opened the door and entered, I found that all the students were bowing their heads in thought, and Teacher Chen also found Wang Yun.Seeing that he was still holding a book in his hand, he walked to the door of the classroom, looked at Wang Yun and asked, "Why are you back? Didn't you mean to return the book?"

Wang Yun raised the book in his hand and said, "I think it's quite early, so I came here."

Teacher Chen nodded and took a closer look. What Wang Yun was holding in his hand was Advanced Mathematics.I froze for a moment, "Can you understand?"

"Almost... I can understand a little bit." Wang Yun smiled awkwardly. He just opened the book and read it all the way on the bus.Even with all the knowledge points in high school, it still seems a bit difficult.Even, it is hard to imagine how to answer these questions.

"Don't force yourself too much." Teacher Chen sighed, "If you have any questions that you don't understand, you are welcome to come to me at any time." Speaking of this, he turned sideways and said to Wang Yunnuzui, "Go in first, whatever you want Find a place to sit down."

Wang Yun walked into the classroom quietly, and none of the students seemed to see that Wang Yun had entered the classroom.Still thinking hard, Wang Yun took a look and saw that everyone was sitting in twos and threes.Only Yuan Chengde sat in the first row, so he went to sit next to Yuan Chengde.

Yuan Chengde raised his head, and when he saw Wang Yun, there was some surprise in his eyes.

"Why are you here?" His voice was very soft, but Wang Yun could still hear his words clearly.Wang Yun also lowered his voice, and replied softly, "After borrowing the book, I saw that the time was quite early, so I came back."

"Borrowed?"

Wang Yun nodded. At this time, Teacher Chen was already standing on the podium.Looking around, he seemed to find that Wang Yun was talking to Yuan Chengde.Coughing lightly, he tapped on the blackboard and said, "Have you figured out this question yet?"

Following his gaze to the topic on the blackboard, he frowned.

This question is not easy!

Yuan Chengde leaned into his ear and said, "How about it, this question doesn't seem easy to do, does it?" Although Wang Yun had several buffs, he still shook his head looking at the questions on the blackboard.

This question is really difficult.Moreover, it is not an ordinary difficulty. If there are levels of difficulty, then Wang Yun feels that this question is at least as difficult as level three or four.For high school students, this question is really impossible to think of.Only Yuan Chengde looked leisurely. Wang Yun looked at Yuan Chengde and said in a low voice, "Do you have a solution?"

"Already have an idea." Yuan Chengde nodded, "But we can't say it yet."

"En." Wang Yunen said, expressing that he knew that Teacher Chen probably wanted them to think for themselves, so Yuan Chengde would not say what his thinking was.

[Before the World Cup football match, in order to inspect 1234567... counting the total playing time of each player, how many different situations did the coaches of country F have? 】

All the students were dumbfounded, and everyone present was a group of people with extremely top grades in mathematics from the Ninth Middle School.Now this question can make them all scratch their heads. Thinking about it, it is also funny.

Teacher Chen walked up to the podium with a chair in his hand, looked around, and said with a smile, "Before I saw that all of you were eager to try, but now you are like eggplants beaten by Shuang, listless."

No one spoke, and at this time, no one dared to speak.

There are not many students in the Mathematical Olympiad training class, only a dozen or so students.This is the first time for them to attend the Mathematics Olympiad training class. After today, they will train together with the seniors and sisters of the second year of high school.As for the third-year students, they are all busy with the college entrance examination, so they will definitely not come to attend any Math Olympiad training class.

Although the Mathematics Olympiad training class is an interest class, it does not mean that you can participate if you want to.First of all, the math score must be good, but this is only the qualification to enter the Mathematical Olympiad training class.The reason why I didn't go to class with the group of seniors and sisters in the second year of high school today is because Teacher Chen still needs to eliminate some of these people.For example, those students who are not suitable for participating in the Mathematical Olympiad, although their math scores are good.But as we all know, high school math is just a starting point.

If you don't even have a complete idea of ​​the high school competition topic, even if you go to participate in the Mathematical Olympiad, it will not just take up a place.

It also delays the time for students to study. It is better to let them spend this time on textbooks. Maybe they can get a good grade in the college entrance examination.

Yuan Chengde touched Wang Yun with his elbow, raised his eyebrows and said with a smile, "What do you think?"

"I have to think about it." Wang Yun shook his head. He had some thoughts, but his thoughts were not clear.Teacher Chen couldn't laugh or cry to the group of students under the podium, saying that he was not disappointed, that was a lie.But to say he was disappointed would be an understatement.After all, this is a competition topic, and this group of students are just in high school, so it's normal that they can't do it.

On the contrary, Yuan Chengde seems to have made up his mind.

Teacher Chen also believed that Yuan Chengde could really solve this problem perfectly.

Looking at his watch, Teacher Chen said, "I'll give you another half an hour, and then I will pick a classmate to do it on the podium. You can write your ideas on paper and hand them in. Even if you do It doesn’t matter if you don’t come out, the key is to have an idea. If you don’t even have an idea...then there’s no need to take classes in the Mathematics Olympiad class. It’s better to go back to the classroom to study more textbooks and get into a good university. It’s better than anything else. .”

Half an hour, whether it is long or not, is not short.As time passed by, Wang Yun blinked his eyes, looked at the blackboard suddenly, and laughed.

Teacher Chen looked at Wang Yun curiously, "Why, do you have an idea?"

Wang Yun nodded, "Almost, I have some ideas."

Teacher Chen also smiled, "Really?" He put down the book in his hand, "Then you can do it on the podium later." Wang Yun nodded, then looked at Yuan Chengde, "I don't know what I think and yours. Is the idea unanimous?"

Yuan Chengde shrugged his shoulders, "Why don't we meet later?"

"I think so."

The other students were still thinking about it. After a while, Teacher Chen stood up and said, "Okay, now the time has come. Come on, Wang Yun, you go to the podium to do it. Other students, don't plagiarize, be yourself Yes. You are all good students, I believe that you can still do well on your own."

After all, Wang Yun stood up.Go straight to the podium and pick up the chalk.Looking at the topic on the blackboard, I thought for a while.

Under the podium, the students talked a lot.There were obviously only a dozen or so students in the classroom, and it was a bit noisy at this time.

"Who is this guy? I thought the teacher would let Yuan Chengde go up?"

"I heard that he is also a student in Mr. Chen's class. We are a dark horse who suddenly came out of this monthly exam."

"In the monthly exam, I was ranked [-]th in the whole grade. Looking at the math results alone, I ranked seventh or eighth in the whole grade. The grades are not bad."

"Shh, stop talking, let's see how he solved it."

[Solution: Let the playing time of each person be 7t1... (t1 is a positive integer)

……

Get the equation 7x+13y=270

……

即6y=4(mod7)，3y=2(mod7)，y=3(mod7)

y=3, 10, 17 correspond to x=33, 20, 7

……

A total of 42244 species]

"..." Wait, what did we see, the front is fine, but what the hell is behind?Why can't I start to understand?

This is no longer a top student, is it?This is the god of learning!Could it be that our school already has a god of learning who can rival Yuan Chengde?

They didn't seem to communicate just now, and they were sitting in the first row. If they communicated, it is impossible for Mr. Chen not to see it.

Putting the chalk in the box, Wang Yun said to Teacher Chen, "Teacher, I'm done."

At this moment, the classroom was completely silent.All eyes were on Wang Yun, as if there was something on Wang Yun.

"What... what's wrong?" Wang Yun looked at all the students under the podium in confusion, and found that their expressions seemed a little dull.He blinked his eyes, not quite sure whether he was right or wrong in his calculation.

"Hmm..." Teacher Chen looked at Wang Yun's writing on the blackboard, and said with a smile, "The idea is very good, and the answer is very clear. The answer...is correct, but the writing on the blackboard is a bit poor."

"..." Except for Yuan Chengde, everyone gasped, I'll go, is there really such a tyrannical existence?The god of learning, it turns out that it is really not a legend.For such a difficult question, I can't even understand the solution behind it, but you can still calculate the answer accurately.

Strong!

No, how did this brain grow?

Jealousy separates my plasmophytes!

Returning to his seat, Yuan Chengde said with a smile, "Although my thoughts are somewhat different, the result is still the same."

Wang Yun smiled, but hadn't had time to speak.Yuan Chengde continued, "After today, I'm afraid you will also be the god of learning in others' mouths."

"Huh?" Before Wang Yun understood what happened, Yuan Chengde said to Wang Yun winkingly, "Everyone here is a math expert in our first year of high school. I read this question. Except me, It’s as if they didn’t even understand the steps you followed to solve the problem, and that’s not to say they didn’t. It’s just that they don’t know why you did it, and if you let them do it. I’m afraid, it’s not as complete as yours.”

"so?"

"So after today, you will definitely become what the teacher said, the god of learning in other classes."

"..." Wang Yun couldn't laugh or cry, he didn't know how to explain this matter.In fact, he himself is not sure whether it is right to do so, but he just follows his feeling.I just feel that doing this is probably the only way he can solve this problem now, but looking at Yuan Chengde's confident eyes, I'm afraid this guy has more than one way.

"One day, I can catch up with you."

"You are always welcome!"

But think about it, the feeling of being a child in someone else's mouth is quite exciting!

Next, Teacher Chen entered into a deep analysis of this question.Especially Wang Yun's answer is the focus of the analysis.The students looked at the answers on the blackboard with some confusion, and nodded with half understanding.

When get out of class was over, the group of students gathered together to discuss.

"Sure enough, the god of learning will only sit with the god of learning. I originally thought that this guy was just better at mathematics, but I didn't expect... there was another terrifying guy like Yuan Chengde."

"It's not right. I remember that he didn't have a full score in mathematics, right? Yuan Chengde is the only one who got a full score in our monthly exam. The rest are more than 140 points, and he is only 130."

"Perhaps people don't bother to do it?"

"No matter what, he's still pretty scary. Teacher Chen explained it for so long, but I still haven't fully understood it. So how did this guy do it?"

"I'm different. I really want to know what's in this guy's mind. He can do it..."

Listening to the discussion of this group of students, Yuan Chengde said amusedly, "You heard me, they are all talking about you."

"Why do I think that the point is on you?" Wang Yun said with a smile, "After all, it is the legendary Yuan Xueshen..."

"Come on, Wang Xueshen, if you studied hard before, you might be better than me." When talking about this, Yuan Chengde said as if remembering something, "You didn't go online, did you?"

"No?" Wang Yun answered Yuan Chengde's question while reading the advanced mathematics.

"There are still people saying what you said on the Internet, do you want to go back?"

"No need." Wang Yun said with a sneer, "My goal is to be the top three in the provincial capital of the Mathematical Olympiad competition. I don't want to fight with those guys. If they want to talk, let them talk. Anyway, I don't plan to go back to the entertainment industry anymore either. I want to be a scientist!"

Yuan Chengde didn't know whether to laugh or cry, "It's fine if you don't take it to heart, but the top three in the provincial capital of the Mathematical Olympiad will be able to participate in the national competition. Do you really plan to do so?"

"Of course." Wang Yun nodded, "You must win the top three in the provincial competition."

"Okay." Yuan Chengde also raised his brows, "It's a deal, how about we go to the national competition together?"

"That is necessary." Wang Yun laughed, "But before that, I have to look at advanced mathematics." Seven days have been removed from one month, and he only has twenty days left up.

There are not many advanced mathematics, and the knowledge points are particularly difficult. He must hurry up and read this advanced mathematics.

Yuan Chengde saw that Wang Yun had worked hard to learn advanced mathematics, so naturally he was not far behind.From the schoolbag, he also took out a book of advanced mathematics that was exactly the same as Wang Yun's, and slowly read it.

The rest time of the Mathematics Olympiad competition training class was relatively long. The two of them concentrated on reading, and the students behind were also curious about what they were doing.Finding that the two had no communication, they quietly came to the first row.I want to know what kind of books they read so fascinated.

It doesn't matter if you don't see it, the first person who came up to observe it screamed in fright.

"What's going on?" The students in the back row looked at the classmate who screamed strangely.
