After Gu Nanyi and Bai Tingting separated, they entered the Class 9 classroom.
Su Wanwan was nibbling a piece of bread, and when she saw Gu Nan entering the door, she raised her hand cheerfully to say hello.
"Nan Yi, come quickly."
Gu Nan walked straight to his seat.
Su Wanwan, like magic, took out a lot of snacks from the table pocket.
Sandwiches, ham sausages, bread, spicy sticks, potato chips, biscuits, etc. were all placed in front of Gu Nanyi.
"Take it, eat whatever you want, I still have pure milk here." After saying that, he reached out and took out a bag of pure milk from his table pocket 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.
I somewhat understand why this deskmate looks so round.
"I've eaten, thank you."
"It's okay, keep it as a snack. I still have it in my desk pocket."
At this time, Huangpu Xixian and Cheng Tianyou walked into the classroom together.
Seeing Gu Nan's pile of snacks on the table, Cheng Tianyou chuckled.
"What a coincidence, I haven't had breakfast today." He reached out to grab the sandwich.
When Su Wanwan saw this, she slapped the back of his hand.
"Go on, I've prepared this for Nan Yi. Huh, if you want to eat, go buy it yourself."
"Su Wanwan, after all, we have been in the same class for three years, how can you be so stingy? Nan Yi is a rich young woman, so she doesn't care about your little snacks."
Gu Nan's eyelids trembled, feeling that there was something in Cheng Tianyou's words.
Huangpu Xixian stared at Gu Nan deeply, then walked straight to his seat and sat down.
Su Wanwan curled her lips: "If Nan doesn't eat, I 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?"
The school bell rings
The first class is mathematics.
The math teacher is an unmarried woman in her forties. Because she has a bad temper and always has a serious expression, the students in Class 9 call her "aunt" behind her back.
My aunt has a bad temper. She teaches math classes for classes six, seven, and nine. The students in these three classes are all afraid of her.
Seeing my aunt walk into the classroom, the originally noisy class became quiet.
On the blackboard, my aunt listed a mathematical formula and began to talk about the ideas for solving the problem.
As soon as Gu Nan heard this, she folded her arms and rested her head on them to catch up on her sleep.
I was thinking about something last night and couldn't sleep at all.
It was already three or four in the morning when I fell asleep. Now that I was listening to such a boring topic, I felt sleepy.
The aunt suddenly stopped and looked coldly in Gu Nanyi's direction.
Seeing this, Su Wanwan hurriedly pushed Gu Nanyi.
"Nan Yi, wake up quickly."
After being pushed awake, Gu Nan slowly opened his lazy eyes, narrowing them displeasedly like a Persian cat, with a hint of evil in his eyebrows.
She blinked and looked towards the podium.
Then he saw the math teacher staring at him with his sharp eyes.
"That classmate, stand up."
Seeing her aunt pointing at her, she stood up straight away.
"Do you understand this question?"
Gu Nanyi glanced at the blackboard and nodded.
My aunt sneered: "Come on, come up and tell us how to solve 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 it first."
The aunt glared at Huangpu Xixian: "Wait a moment and let this new classmate explain how she understands it."
Huangpu Xixian looked towards Gu Nan.
It's okay to sleep, play, and eat snacks in other teachers' classes, but not in my aunt's class. No one in the class dares to mess around.
This girl is in trouble today.
Seeing Gu Nan standing still, the aunt urged in a cold voice: "Don't be stunned. Since you said you understand, 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 Nan was silent for a moment, walked to the podium, picked up a piece of chalk, and walked to a blank spot.
Raise your hand, swish, swish, the chalk moves quickly on the blackboard.
The aunt frowned and stared at her with confusion.
"I asked you to explain the analysis steps of this question to everyone. What are you doing?"
Gu Nan ignored her and quickly wrote a new set of analysis steps on the blackboard.
When she saw Gu Nanyi's analysis, the aunt's eyes suddenly widened and she took two steps forward with shock on her face.
Compared with his own set of analysis steps, Gu Nanyi's set is obviously much simpler and even easier for students to understand.
Moreover, Gu Nanyi's analysis steps are only one-third of the aunt's analysis steps. The words are concise and comprehensive, and the ideas are clearly broken down.
The whole class stared at Gu Nanyi in astonishment.
She was last in her grade, how could she have such a problem-solving idea?
"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 calm tone: "I summarized it myself when I was bored."
Aunt:......
"How could you come up with this without anyone teaching you?" She didn't believe what this girl said at all.
She had heard about this student. Since arriving at No. 1 Middle School, he had ranked last in his grade in the monthly exams for three consecutive months, and was even worse in math.
How could such a student create his own problem-solving steps?
Gu Nan sighed and threw the chalk onto the podium.
"You don't need to ask others to teach you these pediatric questions."
Dozens of pairs of eyes in the class were all staring at her.
Su Wanwan whispered: "My deskmate, 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 my aunt, who had always been so serious about her words, laughing, sent chills down the spine of the whole class.
"Gu Nanyi, come with me."
The aunt handed a pile 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 Nan out of the classroom.
Come to the teacher's office
At this time, the teachers were all in class and the office was empty.
The aunt walked to the desk, opened the drawer, took out a test paper and placed it on the table.
"Come and do this test paper."
Gu Nan glanced at the test paper and saw that the content covered in this paper was much more profound and complicated than high school mathematics.
The coverage is also relatively broad, covering Banach algebra, harmonic analysis, Lie algebra, modern Galenic rates, etc.
This paper is obviously content that only mathematics research will cover.
My aunt sneered: "You think the math questions I teach are too simple, so I will give you a few difficult questions. If you can solve any question on this paper, I will not be able to do anything you want to do in my class from now on."
put one's oar in."
Baby, I can’t cure you?
This paper was given to her by her teacher when she was studying for a PhD. The original intention was to let her continue to do mathematics research.
Therefore, all the questions on this paper are prepared for professional mathematics researchers. Not to mention high school students, even college students may not be able to solve a question.
She just wanted to kill this girl's spirit.
However, Gu Nan remained calm and sat down calmly.
Pick up the pen and start working on the questions.
