"Jiang Han?"

The old man of the Mediterranean recognized Jiang Han at a glance, and he called Jiang Han to his side with a smile.

"You are Director Wu?"

Jiang Han looked at the acquaintance in front of him, and it was the old man he saw in the Oss math competition.

"I am. Professor Wu Changping nodded.

"So it's you, I heard that my special recruitment quota was taken from you?"

"Yes. ”

Jiang Han asked suspiciously: "Didn't you tell me before that this year's Qingda special recruitment quota is full?"

"Yes, it's full. But special students always have to be treated specially!" Professor Wu Changping said with a smile.

Jiang Han didn't say anything more, "Thank you." ”

Professor Wu Changping waved his hand, "Don't thank me, this is the treatment you get by relying on your own strength." From now on, you can study with me, and of course you will have to study other courses as well. ”

"Okay, Professor Wu. ”

"I know that your grades in other subjects are average except for mathematics, but since you have come to Qing University, you must become a well-rounded and good student, and I don't want the students under my command to have people who fail the course. ”

"I'll try. ”

"I don't look at effort, I only look at results. Professor Wu said with a serious face.

Jiang Han nodded.

"Professor Wu, may I ask how to write this question?"

At this time, a senior who was going to graduate school suddenly walked up to Professor Wu's side, took a workbook and began to ask questions.

Professor Wu didn't say anything, took the topic and glanced at it, thought for a while and said:

"This question...... In fact, it is not within the scope of the graduate school entrance examination, which is a bit overclass, so you can put it aside for the time being. Go ahead and do the other topics, and of course, if you really want to know, I can teach you that. ”

The senior scratched his head a little embarrassedly, "Professor Wu, you should tell me about it." ”

"Hmm......" Professor Wu pondered for a while and said, "Okay." ”

He stepped up to the podium and copied the topic on the blackboard.

The graduate students who heard the movement in the classroom briefly broke away from the sea of questions and raised their heads blankly.

It turned out that Professor Wu was about to put on a new topic again.

Everyone cheered up, hurriedly took out pens and paper, and prepared to take notes.

"The knowledge used in this question is actually not difficult, but it is a little complicated, and the logic may be a little confusing, I will sort it out for you, listen to what you can understand, and understand what you don't understand. ”

As he spoke, Professor Wu continued to write the board book on the blackboard.

He would analyze each step in detail, then calculate the result, and continue to deduce the next step, which took about fifteen minutes for the entire blackboard to be written.

Then all of them were wiped and a blackboard was written, and finally only a small blackboard was left waiting for the final deduction.

But at this time, Professor Wu stopped, and the final derivation can be said to be the key to the whole problem, he is a good teacher, because he never asks students to chew something that has been chewed by others.

Every time he gives a lecture, he will leave the most crucial steps for the students to deduce for themselves.

This will help students absorb and understand the topic.

"Okay, that's the last step left for this question, and this last step is also the most crucial step. As long as you understand all the steps I talked about earlier, then this last step will be very simple. ”

Professor Wu turned his face to look at the students in the audience, and saw that everyone was in a daze, and a few of them were still gritting their teeth and thinking, he knew that there were very few people who could really understand this question.

It's not that these students are bad, it's that the question is really difficult.

To be honest, even the graduate students under his command, if they don't listen well and don't take notes and study well, this last step may not be written.

"How's it going, has anyone figured out the last step?"

Professor Wu glanced at the crowd, but none of them raised their hands.

Predictable.

Professor Wu smiled calmly.

"Don't be discouraged, this question is really difficult, even if it is a graduate student I lead, I can't do it if I don't study hard. ”

"Professor Wu, can I try it?"

Suddenly, a voice came.

Professor Wu turned his head to look at Jiang Han, who had just spoken out, and asked with some uncertainty, "Do you understand?"

Jiang Han nodded.

In fact, he still admires Professor Wu very much in his heart, the professor is worthy of being a professor, he also looked at this topic carefully for a while at the beginning and had no clue, or he had a clue but didn't know how to write it.

However, under Professor Wu's careful explanation and combing, he finally clarified the idea of the whole question.

I also learned some problem solving ideas that I hadn't thought of or seen before.

The whole question suddenly opened.

In fact, the last step is not difficult to say, and it is not easy to say that it is simple, because the last step is to sort out the ideas of the whole question, and if you don't understand it before, the last step can't be written.

"I guess I understand. ”

Professor Wu was silent for a while, he actually had a little doubt in his heart.

He just watched me sort out the solution ideas, and he understood?

Isn't that a bit excessive?

As I've said before, even if I'm a graduate student, I can't write the last step if I don't take good notes and do good research.

But on second thought.

This topic is more difficult than the Oss Mathematics Competition, and the knowledge points and solutions used in it are much more difficult than the Oss Mathematics Competition.

However, Jiang Han won the special prize before, so it would be reasonable if he could make this question.

"What's the should?

Come, the pen will give you, you will write.

Jiang Han was not polite, and continued to write down the steps to solve the problem on the blackboard on the side.

It took three to five minutes to add the calculations and checks, and the final steps were finally written, and the final answer was: 1.

Seeing Jiang Han writing the final steps on the blackboard, the seniors in the class couldn't help but jump in their hearts, where did this god jump from?

At first, they were still skeptical, but when they saw Professor Wu constantly nodding his head on the side, they knew that the kid standing on the podium might be right.

After seeing the answer written by Jiang Han, the guy who asked the question hurriedly flipped through the answer after flipping through the book, and he found that the final result was really 1.

O great god!

Just take a look at the topic that Professor Wu said!

"Yes, I was a little skeptical about your results in the competition at first, but now that I've seen your problem-solving process, I don't doubt it at all. The smile on Professor Wu's face was deep.

Now I have found a treasure.

His heart was on fire.

"Xiaohan, do you have any ideas for graduate school? You can consider applying for my graduate school. ”

Jiang Han said helplessly: "Professor Wu, I have only just entered the freshman year, is it too early to decide whether to take the postgraduate entrance examination now?"

"What, freshman?"

The whole class was suddenly alarmed.

The great god in front of you is a freshman who has just entered the school?

Kidding me?
