Time passed by second by second.

For some unknown reason, all the students in the audience felt that Fang Nian was looking at them, and some of them were unable to speak even if the words came to their lips.

Some of them remembered the rumors on the official opening day of school.

I also think of Chen Yao, who was once the No. 1 champion in No. 8 Middle School and is now on leave.

As a result, the noise in the classroom ranged from rustling to audible as a pin drop.

After a while, Fang Nian spoke.

"Those who don't want to attend the lecture can do their own thing. Don't talk nonsense or disturb others."

After thinking for a while, Fang Nian decided to say a few more sentences. After all, he had to take three math classes next.

"I know you are not convinced. Why should I give lectures to you when we are all students? Actually, I don't know why the teacher asked me to teach instead."

"In the past two days, the school has been seriously criticizing the issue of puppy love. I happened to hear a little story and would like to share it with you."

"At your age, it's normal to have someone you like, but it's best to keep it in your heart."

"Because in No. 8 Middle School, it is easy to be caught and disciplined by the political and educational office, and it is easy to be rejected after confessing, and you feel that you are lovelorn. In fact, you have pure unrequited love. To put it nicely, it is love at first sight, but to put it badly, it is lust.

There is no such thing as lovelornness."

There was subtle laughter in the classroom.

Fang Nian knocked on the podium, and the audience fell silent, and then he continued.

"If you like someone, when you think about them, do a math problem."

"When he graduates, put a notebook full of questions in front of him and tell him how much you like him, whether it's a boy or a girl. If you don't believe it, he won't be moved!"

"It will definitely be better than if you rush to turn unrequited love into so-called lovelorn love."

"By then we have a partner and a university!"

After Fang Nian finished speaking, all the students responded with smiles. Some of them were very disinterested and finally asked.

"Doing math problems is just math problems. What does this have to do with listening to you in class?"

Fang Nian smiled: "This is a good question. Let me ask you, will you still do the first exercise in the compulsory mathematics course?"

"If you know how to do it, show me your hand?"

There were very few people in the audience who raised their hands, most of them were still opening their books, and Fang Nian continued to speak.

"Don't want to run before you learn to walk. If you don't listen to my lectures now, besides knowing 1+1=2, what else will you do? How will you finish a full homework book?"

"If you don't listen to my lectures now, how do you know why I can get full marks on exams, but you can't even pass?"

"I won't embarrass you, and you don't embarrass me. Again, it's okay not to listen to the class. Just shut your mouth and don't disturb others' learning."

After a pause, Fang Nian said the last words.

"Don't blame you for what happened today when someone has no partner and hasn't been admitted to a good university. Do you think you can shoulder the responsibility?"

Then Fang Nian straightened up, looked solemn, and shouted: "Class!"

"stand up!"

Li Xue was excited and shouted subconsciously.

In the classroom of Class 174, most of the students stood up after Li Xue, and finally there were 65 people in the entire class——

Fang Nian was also standing.

It's just that few people say the three words "Hello, teacher" next.

Fang Nian pressed his hands together and said, "Please sit down."

"The class will start officially from now on. If you want to listen, listen carefully."

"Do you understand?"

Everyone in the audience: "..."

You look at me, I look at you, but no one talks to me.

Fang Nian didn't care. He glanced at the book a few times and said calmly and in a gentle tone: "First of all, we have to review the set problem."

"Everyone has heard this thing called a collection many times. The written teaching is that it is a whole composed of one or more definite elements."

Fang Nian looked at the audience: "Actually, this thing is very simple."

"For example, this chalk box is a collection, and the piles of chalks of different sizes inside are the different elements in the collection."

"A more complicated thing can be described as: I am in you, and you are in me."

"..."

After a pause, Fang Nian looked towards the audience: "Do you understand everything?"

The audience looked at each other again: "..."

This time Fang Nian paused and asked in a more serious tone: "Don't be mute, just squeak."

As the squad leader, Li Xue quickly took the lead and said: "I understand!"

Because of the unusual start, most of the students in the audience, especially those in the back row, still had their arms folded and looked like they were watching a show.

They want to see how many first and fifteenth days Fang Nian knows!

Fang Nian didn't care about this, as long as it didn't disturb him in class or disturb others in class.

"Attention, look at the blackboard!"

Fang Nian knocked on the blackboard.

"Who can answer this question?"

"Okay, no one raised their hands, right? Li Xue, come here!"

Fang Nian didn't give everyone a chance to react and said directly.

Li Xue stood up and said: "Ziji..."

"..."

Fang Nian's lecture speed was neither too fast nor too slow, and he was smiling and smiling. Some students who were originally unconvinced and wanted to know what kind of virtue Fang Nian had and how he dared to take over the class couldn't help but follow his train of thought.

This time it was not like the last time I gave lessons to a few people including Zhu Pengfei.

There are a lot of things written on the blackboard.

Although the chalk blackboard writing is not as beautiful as the ink pen, it is still enviable.

"What are you doing looking at the blackboard?"

"Look at me!"

Occasionally, Fang Nian would also emphasize his tone to remind everyone to pay attention.

"..."

Although Fang Nian’s lecture was not very fast, because it was a review, the first section of the first chapter ended quickly.

Fang Nian glanced at the book a few times: "This is the end of the review of the assembled questions. Raise your hand if you don't understand."

No one in the classroom raised their hands.

On the one hand, some students didn't want to show weakness, but on the other hand, they really understood.

"Since there is no one, let's review the next knowledge point: functions."

"We learned functions in junior high school."

"The three elements of independent variable, dependent variable, and corresponding rule sound a bit complicated."

When he said this, Fang Nian looked down the stage and knocked on the podium.

"What are you doing looking at the blackboard? Reading!"

"We can see that the concept is not described in detail in the book."

"Let me give you a simple example that you like to hear. For example, if you like someone and you tell him about it, he becomes silent, so you are afraid and quickly say that we should just be friends."

"This process is called a function. If you change with it, it will also change with you. The independent variables, dependent variables, and corresponding rules are all in it."

"A simple example that reflects the mathematical formula is y=x+1, when x=1, y=2.

So when x=-1, y equals 0, which is equivalent to nothing. It's like you were friends to begin with, and after some twists and turns, you finally returned to being friends."

"..."

The first mathematics lesson that Fang Nian taught to his classmates ended with the sound of the bell.

The overall atmosphere in the class was okay.

The students sitting in the front row still followed the lesson plan.

More than half of the people in the back row had a cold-eyed attitude at first, but in the end they couldn't help but follow the train of thought.

After class, Fang Nian returned to his seat and quickly took a drink of water.
