my return to life

"The first phase of make-up lessons for the summer vacation is coming to an end. This time we took the first test for the third year of senior high school, and the results were not very satisfactory."

"August 8st, students!"

"It's one month closer to the college entrance examination in June next year!"

"Hurry up!"

"This holiday will be extended until the 11th. I will return to school on the afternoon of the 10th for evening self-study. Those who can afford it will watch the opening ceremony of the Olympic Games at home."

"The next make-up class arrangement is to have a holiday on the 24th."

"Don't go to Internet cafes after the holiday, don't go to game halls..."

As a cliché, holiday arrangements, Li Donghong mainly expressed these two parts.

It was also at this time that cheers came from every classroom, and class 174 was no exception.

Seeing this, Li Donghong didn't say much at all, and just waved his hand: "School is over."

So, each of them ran faster than the monkeys.

Fang Nian didn't move.

Was detained.

For so many years since he was a child, in Fang Nian's memory, he stayed in the classroom once when he was in elementary school, and this is the second time.

Both times for the same reason.

In primary school, I was selected to participate in the competition for primary school students because of my excellent math performance, so I stayed in class to arrange competition explanations.

This time also because of mathematics.

Seeing Li Annan Dian'er running over, Fang Nian helplessly spread his hands: "Old Zhu asked me to stay."

"???"

The bewilderment on Li Annan's face can be clearly read.

"Why, what personal relationship do you have with the math teacher?"

Fang Nian was almost amused, and explained simply: "Old Zhu gave me a few sets of test papers for me to do, maybe to explain."

"Ah?" The expression on Li Annan's face quickly changed to disbelief.

Fang Nian pretended to be serious and said, "Come on, you can do it next time."

Li Annan curled his lips indifferently: "It's not rare, let's go first, see you in Dream."

Fang Nian could see Li Annan's eyes turned red with envy as he turned his head and left.

Then, there were only seven people left in the classroom.

There was Zhu Pengfei, who had always been number one in the school.

There are also several math scores over 115 points.

Including Zhu Pengfei, Fang Nian was unfamiliar with everyone.

While playing with his mobile phone, Zhu Jianbin walked into the classroom with a stack of test papers.

"It's all there."

"Come up and get the paper."

"I don't talk about the questions that are all done correctly, and focus on the questions that are easy to make mistakes."

Zhu Jianbin directly entered the topic without any ambiguity, without wasting everyone's time at all.

Except for Fang Nian, several other people sat around the podium, and some of them could get the papers without getting up.

Fang Nian got up and walked to the podium, Zhu Jianbin took his paper and said.

"Your correct rate of basic questions is the highest this time. Let me tell you about a few error-prone questions that I circled."

Fang Nian slowly raised three question marks: "???"

Zhu Jianbin quickly lost his eyes.

He finally understood that Fang Nian had always treated him as an equal, which he felt was good.

Right.

After all, Fang Nian worked hard from the mud to the upper level of the pyramid. Although his body has returned to youth, his psychological maturity is still there.

Fang Nian touched his nose: "Okay."

Standing on the podium, he glanced at the few people sitting under the podium.

Fang Nian's expression became serious.

After thinking for a while, Fang Nian decided to proceed in an acceptable way, cleared his throat and said, "Everyone, turn to Math Paper 1, Question 6."

"This question is a fill-in-the-blank question."

“已知f（x）=ax+x/b，若-3≤f（1）≤0，3≤f（2）≤6，求f（3）的范围。”

"We all know that mathematics is actually very romantic, such as dividing 9 by 3, I am you besides you."

"Going back to this question again, using the simplest formula as a question will allow us to understand that this is a transformational equivalence problem."

"Why is it easy to make mistakes? When a function that satisfies the conditions is used to obtain a value, it is easy to ignore the close connection between a and b, which is as close as my heart to yours;

We all know that the value of functions is a perfect thing, absolutely unambiguous at all. "

"So, this value range is not only limited by a, but also by b."

"So, do you know what the answer is?"

With that said, Fang Nian looked at the audience.

Zhu Pengfei, who had been the number one in the school for a long time in mathematics, raised his head and opened his mouth, unable to speak. Although you speak well, how can you do your calculations so fast?

“答案是16/3≤f（3）≤37/3。”

"The problem-solving process is a romantic road leading to the truth, so I won't write about it."

"Okay, next is question 9, a multiple-choice question. The common mistakes of this question are also very simple..."

"..."

"This question is also very simple. You can figure it out in a minute or two, so I won't write it down..."

Then Fang Nian clapped his hands: "The teacher asked me to explain all the error-prone questions, and everyone understands?"

Zhu Pengfei answered, "Understood."

"I understand too."

"..."

"Okay, everyone understands, teacher, come here." Fang Nian quickly stepped aside.

He understands the basic questions, but he doesn't understand a few of these three sets of test papers.

Zhu Jianbin glanced at Fang Nian, who had quickly slipped away, and then at the blackboard without a single word. The expression on his face was wonderful for a moment.

"Do you really understand?"

Although he actually believed it in his heart.

Because, even he almost felt that mathematics was really as romantic as Fang Nian said.

It's not a few things that can't be made even if you are in a hurry.

In this state, everyone's listening state must be good.

Sure enough, everyone in the audience nodded their heads, and even wished that Fang Nian would talk a little longer.

There are a total of 69 questions in the three sets of papers.

Fang Nian talked about five topics.

Next, Zhu Jianbin spent half an hour speaking on nine topics, basically covering all intractable diseases.

Of course, this is only for the few people present.

"Teacher, who has the highest total score among these three sets of papers, is it Zhu Pengfei?" a classmate asked.

The corner of Zhu Jianbin's mouth twitched slightly, but he still answered the heart-wrenching question: "Although Zhu Pengfei got a high percentage of points for the major questions, Fang Nian got the highest total score, and he got all the basic questions right."

"The questions this time are relatively close to the difficulty of the college entrance examination. The three sets of papers have a total of 450 points, and Zhu Pengfei's total score is 373 points."

"Fang Nian's total score is 390, so don't just focus on the big questions, the basic questions can also widen the gap!"

"Just like the five questions that Fang Nian talked about just now, I know that some of you may have figured it out after reading the paper, but can you understand it so thoroughly?"

"Fang Nian has almost zero foundation. As far as I know, he just finished the compulsory courses and didn't read a single word of the elective courses. It can be seen from his answers that he basically doesn't understand geometric proofs. The titles are all wrong."

"And, he was the last one to get the test paper."

"..."

After Zhu Jianbin's words fell, everyone looked at Fang Nian in surprise again.

The lectures are so humorous and pleasant, and the exams are so good.

Is this genius?

Especially Zhu Pengfei, whose face was full of caution and vigilance, but no one said a word.

Fang Nian didn't say anything, but thought a little playfully, "So soon we started hitting our classmates?"

But he didn't take it to heart. For him, learning is really just an intuitive form of enjoying youth.

Broken bowl.

Chapter 12 Excellence is always accompanied by jealousy and gossip

"Fang Nian, wait a moment."

Seeing Fang Nian packing up his things and preparing to leave, Zhu Jianbin on the podium waved quickly.

Fang Nian looked over: "What's the matter, Lao Zhu?"

While talking, he simply tidied up the desk. A pile of books was stacked in front, and a pile of books was stacked in the back, neatly forming a right angle.

Then take out a 5 yuan fare and a 20 yuan backup, put the mobile phone in your pocket and work together.

"Is this going to go back empty-handed?" Zhu Jianbin said seeing Fang Nian empty-handed.

Then he took out the cigarette case and glanced at Fang Nian: "One?"

There were only the two of them left in the entire teaching building, and Zhu Jianbin, who realized that Fang Nian was mentally mature, didn't care much about these details.

"No, if anyone sees this, I'm afraid it will be rumored for half a year."

Seeing Zhu Jianbin holding a cigarette and lighting the fire, Fang Nian helped to block the wind.

The two walked down the stairwell side by side.

"Are you okay?" Fang Nian asked proactively.

Zhu Jianbin took a deep breath and blew out a beautiful smoke ring.

"It's nothing, I just want to ask how you are so proficient in basic knowledge."

"I just wanted you to try it, but I didn't expect it to be bigger than I expected."

"The humorous and interesting way of teaching, even I almost thought that mathematics is really as romantic as you said, no wonder you are good at Chinese and usually read a lot?"

"Is there any special way?"

Listening to Zhu Jianbin's admiring words that seemed to ask for advice, Fang Nian touched his nose.

"What else can you do if you are proficient in basic knowledge, only if you are familiar with it."

"For the lectures, I take it from the perspective of a student. I prefer to be humorous and lively."

"..."

If I have to say it, it is not only related to Fang Nian's rich reading, but also related to the fact that he was often invited to speak at business events in his previous life.
