After the Mid-Autumn Festival, there is a monthly exam, and there is no comprehensive statement in the first semester of high school, so it is necessary to test six subjects: language, mathematics, foreign language, physics, chemistry, and life.

Two subjects a day, a total of three days, after the exam, while waiting for the teacher to correct the marking, while attending class to listen to the teacher to comment on the test papers.

But the subject teachers are very tacit, seeing that everyone is going to celebrate the National Day, they will give everyone a good mood, so they will not comment on the test papers and will not announce the results ranking.

It's just that in the last class before the holiday, the math teacher Lao Chen played a game of suppression and suddenly explained the optional fill-in-the-blank questions.

Everyone is like a puppet with a broken line, looking at the multiple-choice answer "ADBDD CDCDA BB" given on the blackboard, and I don't know whether to talk about it or not.

Half wrong, that's what most of the class said.

Even if you are good at partial math, you have to make two or three mistakes.

"How did you do on the exam?" Shen Yan finished the answer, and it was already the basic exercise to fill in all the options.

"All right." Jiang Wen spread out the test paper, and it was also his basic exercise to fill in all the corrective ones.

When the girl next door heard this, she looked down at the test paper where she had made three or four multiple-choice questions and two fill-in-the-blank questions, and fell silent.

Where are these two people's livestock, how can they be so capable of fighting?

Shen Yan didn't pay attention, just stared at Jiang Wen's subtle eyes, unconvinced, "What about anything else?" The big question? ”

“…… Isn't that still unanswered? ”

Jiang Wen felt that she was quite competitive!

"That's how we both face each other."

“…… Okay, too. ”

"17 questions - 2/3, same."

"Question 18 - Root number 6/5, same."

After all the passes, until the first small question of the last big question, the answer is the same.

Finally, Jiang Wen looked at the second small question of the last big question.

In the past, before he touched the last question, the bell rang.

This time, he was able to finish the entire test paper, thanks to the notes that Shen Yan gave him.

He saved a considerable part of the calculation steps.

Jiang Wen glanced sideways at Shen Yan's delicate side face, and was a little grateful.

At this moment, Shen Yan turned his head to face it.

“！” He was a little embarrassed to peek and be discovered.

Shen Yan stared at the test paper seriously and didn't pay attention to anything, and said, "You made a mistake in the second question of the last question." ”

"Huh?" Jiang Wen raised his eyebrows slightly, and immediately compared the answers to their second question.

This is an elliptic problem, which calculates a fixed point.

The fixed point he calculated was (1,2/3)

The fixed point calculated by Shen Yan is (2,5/3)

Shen Yan said bluntly: "You must be wrong." ”

Jiang Wen slowly typed a question mark: "? ”

Six, so confident that you are right? Is it a mule or a horse that comes out to slip around?

Shen Yan put out the draft and was about to calculate it, and glanced back provocatively.

Yo-yo is yo-yo!

Immediately, they exchanged math papers and began to check each other's steps.

Shen Yan discovered Jiang Wen's mistake and said bluntly: "You don't understand it right here!" y=kx, and it should not coincide with the x-axis. This expression is obviously a straight line, how do you take the point (0,0)? ”

Jiang Wen was unconvinced: "This question is to find a fixed point, which means that the k value can be taken no matter what." Take k=0, y=kx, y=0. And it doesn't say that y=kx is a line, so you can think of this equation as (0,0). ”

"How is that possible?!"

“！” Neither of them was convinced by the other, and they argued from class to class.

Although the voice was small, Lao Chen still heard it.

Lao Chen walked over, looked at the papers of the two, and then looked at the reference answer in his hand, and said: "The last question, the question is ambiguous, and there are two understandings: y=kx, which can be the point of (0,0) or a straight line. There should have been a condition, k is not equal to 0, and it was leaked when printing, so both answers are correct. ”

Shen Yan: "......"

Jiang Wen: "......"

day, white fight for a long time.

When the bell rang for the end of school, Shen Yan beckoned, "See you at ten o'clock tomorrow morning." ”

Jiang Wen nodded.

The promised promise must not be forgotten.

So on the first day of the National Day, he woke up at half past nine in the morning.

Zhao Han was surprised why this child woke up so early, in the past, he slept until after two o'clock in the afternoon before getting up for breakfast.

Jiang Wen didn't want to get up so early, but he had an appointment at ten o'clock to give Shen Yan the first lesson in writing a novel.

So I took a few bites of tomato and egg noodles, changed my shoes and went out.

"Mom, I'm full, I'm going to the library, and I'm not coming back for dinner at noon."

"What are you doing in the library so early? It's rare to have a holiday, so sleep at home more. ”

"Harm, just, there is a book I want to read...... Okay, okay, I'll go first. "Going to the library is just an excuse, he has to slip away quickly, and if he continues to talk about it, he will reveal the stuffing, Jiang Wen didn't want to be asked early in the morning, so he was asked if he arched which cabbage.

"Hey, but at noon today, your aunt invited our family to eat fish." Mother Zhao Han's voice came from the kitchen.

Jiang Wen's action of tying his shoelaces stopped.

"Let's go out after lunch."

“…… Forehead. Jiang Wen was in a dilemma.

Auntie, my mother's sister, works in the field, and can only come back during the holidays.

When I was a child, I was very kind to him, buying him clothes, snacks, and all kinds of things.

If you don't see the previous side, it will be somewhat rude.

"You're not going to have an appointment with your classmates, are you?" Seeing Jiang Wen's embarrassment, Zhao Han contacted his abnormal early riser, and suddenly thought of this possibility.

“…… No, I'm just borrowing a book. But when he replied, Jiang Wen hesitated.

Zhao Han obviously saw the problem, and looked like he didn't understand: "Then you go." ”

With that, she rummaged through her bag for something.

“！” Jiang Wen was surprised, and thought that he would have to accompany his aunt to finish eating before leaving.

"Take more money."

"What?"

Facing the few red tickets handed over by his mother Zhao Han, Jiang Wen didn't understand what it meant.

Mother Zhao Han directly put the red ticket in his schoolbag, closed the zipper, and said seriously: "Remember to invite other girls to have a good meal." ”

"It's not ......"

Mom, you listen to my quibbles, no, Mom, you listen to my explanation!

"Remember to send people home at night." Mother Zhao Han also told him seriously, with an expression of not acting according to instructions and interrupting his dog's legs at night.

"Hey, this ......" really can't be washed by jumping into the Yellow River.

"Alright, get out of here, take care of the people." Zhao Han waved his hand.

"I ......" Jiang Wen tied his shoelaces and decided to explain clearly before going out.

But Zhao Han pushed him out directly.

"Click!"

The next second, the sound of the door closing sounded.

Jiang Wen: "......"

This?

Mother?
