Madam, she's a full-time boss

After Gu Nanyi and Bai Tingting separated, they entered Class Nine.

Su Wanwan was nibbling on a piece of bread, and raised her hand cheerfully when Gu Nan entered the door.

"Nan Yi, come quickly."

Gu Nan went straight to his seat.

Su Wanwan took out a lot of snacks from the table pocket like a magic trick.

Sandwiches, ham sausages, bread, spicy strips, potato chips, biscuits, etc. were all placed in front of Gu Nanyi.

"Here, eat whatever you want, I still have pure milk here." Then, he reached out and took out a bag of pure milk from the pocket of the table and put it on Gu Nan's table.

Gu Nan looked at the table of snacks in front of him, and then at Su Wanwan.

Some understand why this tablemate is so round.

"I have eaten, thank you."

"It's okay, keep it as a snack, I still have it in my pocket on this table."

At this time, Huangpu Xixian and Cheng Tianyou walked into the classroom together.

Seeing a pile of snacks on Gu Nan's table, Cheng Tianyou chuckled.

"What a coincidence, I haven't had breakfast today." He reached for the sandwich.

Seeing this, Su Wanwan slapped him on the back of his hand.

"Go ahead, I prepared this for Nan Yi. Hmph, if you want to eat, go buy it yourself."

"Su Wanwan, at least we have been in the same class for three years, why are you so stingy? Nanyi is a rich little woman, so she doesn't care for your little snacks."

Gu Nan's eyes trembled, feeling that there was something in Cheng Tianyou's words.

Huangpu Xixian took a deep look at Gu Nan, then went straight to his seat and sat down.

Su Wanwan curled her lips: "If Nan doesn't eat, she won't give it to you."

Cheng Tianyou threw his backpack on the table and sat down.

"If you don't get it, who cares."

class bell rings

The first class is mathematics.

The math teacher is an unmarried woman in her 40s. She has a bad temper and always has a serious expression. The students in Class [-] call her "big aunt" behind their backs.

My aunt's temper is not ordinary. She leads the math classes of six, seven, and nine classes, and the students in these three classes are afraid of her.

Seeing my aunt walk into the classroom, the noisy class became quiet.

On the blackboard, my aunt listed a mathematical formula and began to talk about the solution to the problem.

As soon as Gu Nan was bored, he folded his arms, put his head on his arms and began to catch up on sleep.

I was thinking about something last night and couldn't sleep at all.

By the time I fell asleep, it was already three or four o'clock in the morning. Listening to such a boring subject right now, I felt drowsy.

The aunt stopped suddenly, and her cold eyes suddenly looked in Gu Nanyi's direction.

Seeing this, Su Wanwan hurriedly pushed Gu Nanyi.

"Nan Yi, wake up quickly."

After being pushed awake, Gu Nanyi slowly opened a pair of lazy eyes, and squinted displeasedly like a Persian cat, with a hint of treachery in his brows and eyes.

She blinked and looked towards the podium.

Then I saw the math teacher staring at me with sharp eyes like a pair of blades.

"That classmate, stand up."

Seeing her aunt pointing at herself, she stood up straight.

"Do you understand this question?"

Gu Nan glanced at the blackboard and nodded.

The aunt sneered: "Come on, come up and tell everyone about the solution to this problem."

Gu Nan frowned, and stood still.

Su Wanwan looked at her worriedly.

Huangpu Xixian raised his hand at this time: "Teacher, I want to explain first."

The aunt glared at Huangpu Xixian: "Wait a minute, let this new classmate explain how she understands it first."

Huangpu Xixian looked at Gu Nan.

It’s okay to sleep, play and eat snacks in the class of other teachers, but the class of my aunt is not good, no one in the class dares to mess around.

This girl hit the gun today.

Seeing Gu Nan standing still, the auntie urged in a cold voice: "Don't stand still, since you said you understood, come up and explain your point of view to everyone, come on."

The whole class was staring at her, most of them waiting to see her make a fool of herself.

Gu Nanyi was silent for a moment, then walked up to the podium, picked up a piece of chalk, and walked to the blank space.

Raise your hand, swish, swish, and the chalk moves quickly on the blackboard.

The aunt frowned and stared at her suspiciously.

"I want you to explain the analysis steps of this question to everyone. What are you doing?"

As soon as Gu Nan ignored her, he quickly wrote down a set of analysis steps on the blackboard.

When she saw Gu Nan's set of analysis, the aunt's eyes widened suddenly, and she took two steps forward with a face full of shock.

Compared with his own set of analysis steps, Gu Nanyi's set is obviously much more concise, and even easier for students to understand.

Moreover, Gu Nanyi's analysis steps are only one-third of the analysis steps of Auntie's set. The words are concise and the ideas are clearly decomposed.

The whole class stared at Gu Nanyi in astonishment.

She was the bottom one in her grade, how could she have this kind of problem-solving thinking?

"Where did you learn this set of problem-solving steps?" After the shock, the aunt asked doubtfully.

Gu Nan played with the chalk in his hand, and said in a light tone, "I summed it up by myself when I was bored."

Auntie: ...

"No one taught you, how could you come up with this?" She didn't believe this girl's words at all.

She had heard about this student. Since he came to No. 1 Middle School, he was No. [-] in the monthly exam for three consecutive months, and his math was even worse.

How could this kind of students create their own problem-solving steps?

Gu Nan lightly put the chalk on the podium.

"These pediatric questions don't need to be taught by others."

Dozens of pairs of eyes in the class were all staring at her.

Su Wanwan whispered: "At the same table, you are so Versailles, I can't help but want to hit you."

The aunt stared at Gu Nan for a long time, and suddenly, she laughed.

Seeing the always serious aunt laugh, the whole class felt chills down their backs.

"Gu Nanyi, come with me."

The aunt handed over a stack of test papers on the table to the math class representative and asked her to distribute them to the whole class.

Immediately, she led Gu Nanyi out of the classroom.

come to the teacher's office

At this time, the teachers are all in class, and the office is empty.

The aunt went to the desk, opened the drawer, took out a test paper and put it on the table.

"Come and do this test paper."

As soon as Gu Nan glanced at the test paper, the content covered in this paper was much more profound and complicated than high school mathematics.

It also covers a wide range of topics, covering Banach algebra, harmonic analysis, Lie algebra and modern Galenic rate, etc.

This paper is obviously only involved in mathematics research.

The aunt sneered: "You think the math problems I taught are too simple, so I will give you a few difficult problems. If you can solve any problem on this paper, I will not know what you want to do in my class from now on." put one's oar in."

Baby, still can't cure you?

This paper was sent to her by her teacher when she was studying for a doctoral degree. The original intention was to let her continue to do mathematics research.

So the questions on this paper are all prepared for professional mathematics researchers, let alone high school students, even college students may not be able to solve a question.

She just wanted to kill this girl's vigor.

However, Gu Nan calmly sat down with a calm expression.

Pick up the pen and start working on the questions.
