Hey, the science next door

Jiang Li just followed him. In the dark night, the wind was still very cold, but with one more person to accompany him, the loneliness didn't look so embarrassing, and the dim street lights illuminated the grove also looked ambiguous.

The young couples who are in an underground relationship are also playing around in this night, and from time to time pay attention to whether there is a teacher or the like.

Shen Yu didn't say a few words along the way, very quiet.

When we arrived at the teaching building, the mathematics competition class was in the lecture hall on the first floor, and there were already many people sitting there. Zhou Yang sat in his seat and didn't know what to study. He looked serious as if he wasn't Zhou Yang.

Knowing that he would ignore anyone when he was serious, Shen Yu took Jiang Li to the back row, but he didn't know that he thought Shen Yu and Zhou Yang had a conflict.

This place is basically the top students in No. [-] Middle School, because it is a mathematics class, and arts and sciences are divided together, so everyone is familiar with it.

Lin Xiao and Xu Nuo were together, sitting behind Shen Yu Jiangli.

A math teacher came to the conference room, Jiang Li stared at it for a long time, wanting to laugh, this is his head teacher, Wu Chang.

Teacher Wu Chang smiled at everyone, put the yogurt in his hand on the podium, and joked: "It was given by someone else."

The students in the audience smiled friendly, and the slightly awkward atmosphere became much more harmonious.

Three hours of evening self-study, math class takes up one hour.

Basically, they are talking about competition questions, and most of them are extended training.Jiang Li has some headaches about mathematics. It's not that he is bad at mathematics, but that he always feels different from others. He thinks that he is not born with a very smart mind.

Shen Yu was serious, and naturally took the pen and paper in front of Jiang Li, and began to count the questions on the blackboard.

"You didn't bring anything, did you?" Jiang Li asked him in a low voice.

"Yes." Shen Yu replied while writing, "Pay attention to the class."

Jiang Li approached him and used the same draft paper as him.

The two of them were very close, Lin Xiao and Xu Nuo were watching behind them almost dying of excitement, staring at the hands of Shen Yu and Jiang Li under the table, as long as they touch again, they will meet!

At this time, Teacher Wu Chang turned around with a smile on his face: "I will invite two students to write on the blackboard for this question. Shen Yu and Zhou Yang, go to the blackboard."

Hold.Xu Nuo and Lin Xiao stared at the blackboard angrily.

Shen Yu was quite surprised, he stopped writing, glanced at Jiang Li, and got out of the seat behind Jiang Li.

Jiang Li was still looking at the questions on the blackboard, without any thought at all, and then looked at Zhou Yang and Shen Yu, both of them also had serious expressions, and it seemed that they still hadn't thought about it.

Jiang Li thought deeply, to see if he could pick it up.

Zhou Yang and Shen Yu walked to the podium, holding chalks, and bowed their heads together.

"How?" Zhou Yang asked cautiously.

"It's going to overturn." Shen Yu answered absent-mindedly.

Zhou Yang and Shen Yu stood in front of the blackboard without writing for 5 minutes. Jiang Li looked at the blank draft paper and realized the horror of the competition for the first time.

Zhou Yang was the first, slowly raised the chalk in his hand, and wrote an ugly solution on the blackboard.

Shen Yu glanced at it, raised his hand, and wrote an explanation on the blackboard. The words were much prettier than Zhou Yang's.

Then there was another silence between the two.

Teacher Wu Chang is drinking yogurt. This is a good start, and it looks pretty good. Teacher Wu Chang has been looking for this question for a long time. It is typical and competitive, and it is also very difficult.Let this group of high-ranking top students lower their mentality.

Zhou Yang and Shen Yu are candidates who have already thought about it.The styles of the two questions are different.

Zhou Yang began to write down the first formula, which was a very basic formula, and then calculated slowly. Jiang Li also thought of this method, but it would be too troublesome to calculate this way.

Jiang Li watched Zhou Yang on the stage writing non-stop, while Shen Yu on the side didn't write for a long time.

Zhou Yang almost filled the entire blackboard.

Shen Yu lowered his head, said softly, and began to write down the first formula on the blackboard. The students under the stage still remembered the first formula, but the second formula, the students began to look at a loss.

"Awesome." Xu Nuo looked at Shen Yu appreciatively.

"What, did he make it up?" Lin Xiao asked from the side.

"This is a very unpopular formula, what's it called? I forgot, it's awesome anyway." Xu Nuo also began to calculate on the draft paper.

Zhou Yang and Shen Yu finished answering the questions at the same time.

Zhou Yang had a little more than a whole blackboard, and Shen Yu only took up a small half. The answers of the two were exactly the same.

Teacher Wu Chang smiled and let the two students go down with an expression I knew.

"First of all, it is right to congratulate these two students!" Teacher Wu Chang took the lead in applauding.

Shen Yu returned to Jiang Li's side expressionlessly.

"Awesome." Jiang Li said two words of appreciation.

"Are you amazing?" Shen Yu asked again with a smile.

"Fantastic, great." Jiang Li was busy doing calculations, so he dealt with it first.

"You don't even look at me." Shen Yu said softly.

There is nothing wrong with this sentence, but the tone?

Jiang Li raised his head slightly to look at Shen Yu, Shen Yu lowered his head and drew circles on the paper with a pen, looking aggrieved?

"Are you... all right?" Jiang Li suspected that mathematics makes people stupid.

"It's okay." Shen Yu returned to normal again, looked at Jiang Li and smiled.

"Student Zhou Yang answered the questions very rigorously and used methods that everyone can think of, but it was a waste of time. Student Shen Yu wrote very simple, but we did not learn the formulas used. In other words, the whole high school A formula that doesn't even appear in textbooks." Teacher Wu Chang explained.

"Of course, the college entrance examination does not recognize this formula." Finally added a sentence.

"I knew it." Shen Yu said calmly, playing with the pen in his hand, looking a little irritable.

"Then you still use it?" Jiang Li asked from the side.

"I'm too lazy to write so much, and it looks quite tall." Shen Yu said.

"So the two students have their own flaws, so let me popularize science for you, which formulas are not only useful but also recognized by high school education." Wu Chang wiped off the blackboard with a smile.

Zhou Yang was so angry that he spat out a mouthful of old blood.

After co-authoring for a long time, I and Shen Yu were used as examples.

Jiang Li wanted to laugh.

"What are you laughing at?" Shen Yu asked him.

"It's nothing, you stood up and didn't write for a long time, I thought you were going to overturn." Jiang Li took out his notebook and prepared to write down the formula.

"Then what should I do if I flipped through it?" Shen Yu snatched his notebook, and tore off two pages very undistressed.

"It's normal for you to turn it over." Jiang Li frowned and snatched back the notebook, but failed.

"What do you mean by that?" Shen Yu deliberately prevented Jiang Li from getting the notebook.

"Give it to me!" Jiang Li was a little anxious.

Shen Yu looked at his anxious look, suddenly got playful and said something.

"Call husband."

Jiang Li was taken aback.

"The students in the back pay attention to the records, and listen to the class carefully!" Wu Chang knocked on the podium and looked towards Shen Yu and Jiang Li.

Jiang Li began to look at the blackboard seriously, but his mind was still on the notebook.

"You're screaming." Shen Yu leaned close to his ear and whispered.

It's abominable.
