Before class, there was a middle-aged woman standing in the corridor at the door of the classroom, holding a math textbook and lesson plan in her hand, which should be the math teacher.

The math teacher, with his hair meticulously combed and a bun at the back of his head, had a dogmatic stereotype on his face, and looked at the students who were laughing and playing everywhere in the hallway, frowning and dissatisfied.

"! The exterminator is here, wake up, don't sleep! ”

"Did you write your math homework? Lend me to copy. ”

"Damn, is Lao Tzu good at math? You don't know? ”

Looking at the classmates around him who were borrowing homework like headless flies, Xia Nanxing was very calm.

"Woooooo

"What's wrong?" Xia Nanxing asked worriedly.

"I... Hiccup..."Before he could finish speaking, he hiccuped"... I can't write my math homework, and the exterminator won't let me go..."

Looking at Michelin, who was looking at the frightened, Xia Nanxing was surprised, "Is the math teacher really so good?" ”

Michelin nodded heavily, "It's amazing," thought about it and whispered to Xia Nanxing: "The math teacher has a deep background, no one dares to offend, and the students don't dare to be too presumptuous in front of the math teacher!" ”

Xia Nanxing was stunned, no wonder!

She said, this group of gentlemen doesn't even pay attention to the head teacher, how can they be afraid of a math teacher.

It turns out that this teacher has a strong background!

Xia Nanxing liked this tablemate very much, and when he saw that the tablemate was crying helplessly, he said, "You don't know which question?" ”

"Will you?" Michelin was surprised, and tried to stare at Xia Nanxing with a pair of small eyes.

Xia Nanxing nodded: "Yes!" ”

Xia Nanxing has been smart since she was a child, and she almost never forgets it, in the previous school, the first age was always hers!

"Great."

Michelin wiped away her tears and took out her math textbook and homework book.

Point out the homework questions to Xia Nanxing.

It's a very simple trigonometric model application problem.

Xia Nanxing pointed to the question type, not even scratch paper, Xia Nanxing learned mental arithmetic when he was a child, and rarely used scratch paper for math problems, using mental arithmetic faster than the computer, but he solved the problem in the blink of an eye.

Pity...

Michelin looked at the math problem in front of him blankly, always feeling that it knew itself, and he didn't know it...

"Got it?"

"Huh? What the? Michelin looked innocent, and his eyes were blank and blind.

"Huh?"

"You're too good at the same table, you can do such a difficult question," Michelin is not stupid, he came up with a compliment, and finally made a summary, "However, I still can't." ”

After speaking, he bowed his head shyly.

"This?"

Xia Nanxing felt that she had spoken very carefully, but she still couldn't understand it at the same table, what should I do?

Xia Nanxing looked at the homework questions circled in the textbook again, there were not many, just three, and after thinking about it, he took out a clean notebook from his bag and wrote the answers to the questions.

Three questions, Xia Nanxing only took a few minutes to write.

"Oh," Xia Nanxing handed the notebook in the direction of Michelin, "Do you want to see it?" ”

Regarding the fact that her classmates copied her homework, Xia Nanxing said: She has been used to it since she was a child!

"Well," Michelin nodded quickly, looking at Xia Nanxing with a pair of hot eyes, "Xia Xia, you are really good!" ”

Michelin copied his homework and said, "When you get better from your cold, I will definitely treat you to a big meal." ”

Wei Yan was called up by a friend, his eyes were misty, he was holding a homework book in his hand, and sighed mournfully, "You haven't done your homework, what are you asking Lao Tzu to get up for?" ”

"If you don't have homework to copy, you might as well sleep!"

"Boss Yan," Wei Yan looked sideways at Yan Wuji, who was woken up by Xiao Xiao, "Did you write your homework?" ”

"Write your mother," Yan Wuji supported his chin with one hand, his face was full of nonchalance, "Lao Tzu has no time to write." ”

Wei Yan and Yan Wuji have been brothers for a few years, and they are used to fighting on weekdays, and they come as soon as they open their mouths for swear words and yellow jokes.

"Boss Yan, you're awesome," Wei Yan gave Yan Wuji a thumbs up.
