Chapter X

The two-hour torturous math exam was finally over, and after Bi Qi and Ma Zhengxuan collected the test papers, they sent them to Gu Lu.

As soon as they walked out of the classroom, Bi Qi and Ma Zhengxuan glanced at each other, both smiling bitterly.

"How's the test?" asked Bi Qi first.

Ma Zhengxuan shook his head, "It's not good." The big questions in the back are okay, and the choices in the front are filled in the blanks, and there are three that will not be, and a few that are not quite sure. ”

Bi Qi sighed, "I'm similar to you, there are a few questions, but I can't think of a solution to the problem after racking my brains." ”

While speaking, the class representative of Class 17 next door also walked out of the classroom with a roll.

Several people looked at each other, speechless.

"Teacher, the papers have been collected. In the office of the mathematics group, Bi Qi said to Gu Lu, who was sitting at the desk.

Gu Lu pointed to a position on the table, "Just put it here." ”

"What's the matter, don't leave yet, what's wrong?" Gu Lu glanced at Bi Qi who was standing still, and said with a smile.

Bi Qi rubbed his hands, "That, teacher, do you have the answers to the weekly test questions this time?"

"Oh, yes, I forgot about it, you wait here, I'll hit it right away. As he spoke, Gu Lu created a new document on the computer, without even looking at the title, and his fingers were tapping quickly on the keyboard.

Lines of formulas appeared on the screen, during which Gu Lu did not have any thoughts or pauses.

Bi Qi's mouth grew in surprise, "Teacher, what are you ...... Write the answer?"

"What, what's strange?" Gu Lu asked distractedly as he tapped on the keyboard.

Bi Qi swallowed hard, "No, no ......"

A few minutes later, Gu Lu handed the printed answer to Bi Qi.

"Then teacher, I'll go first. ”

"You wait. Let me ask you something. ”

Gu Lu rubbed his chin and asked, "How do you feel about today's set of test papers?"

For the first time, Gu Lu still wanted to hear the feedback from his classmates.

"Very good!" Looking at Gu Lu's expectant gaze, Bi Qi said against his will.

"Really?" Gu Lu tilted his head in a suspicious tone.

"Really!" Bi Qi nodded heavily, "When I collected the test papers, several of my classmates insisted on holding the test papers and didn't let me take them, which shows how much they like this set of test papers." There were even a few classmates who were moved to tears on the spot!"

Gu Lu smashed his mouth with satisfaction, "Since the classmates' evaluation is not bad, then next time I will follow this standard." ”

After speaking, Gu Lu waved his hand, "Okay, it's nothing for you, let's go." ”

Students, I really didn't mean to harm you! I was forced by Teacher Gu to say such things against my will!

Yes, that's it, I was forced!

After comforting himself, Bi Qi turned and walked away.

…………

On the other side, in the classroom.

According to common sense, they used to go directly to the cafeteria to eat after handing in the test papers.

But this time no one did, but they got together in twos and threes and had a heated and loud discussion.

"Damn, what kind of fairy question is this, the first fifteen choices and fill in the blanks, how many will you have?"

"Three ways. ”

"I'm also three. ”

"I'll only do two. ”

"Boom, I can say I can't do it!"

"What, can I ask weakly, is the exam paper difficult this time?" Such an abrupt voice made many people in the classroom look inexplicable.

Which big guy said such an arrogant sentence?

Listening to the tone, it seems that he is very disdainful of the difficulty of this math paper.

The crowd looked in the direction from which the voice came from, and saw a stout boy sitting in the last row of the classroom near the trash can.

Everyone held their foreheads together.

Indeed, for the perennial first in the class, it is indeed not surprising that he can say this.

After all, the test paper is easy or difficult, and it is the same concept for him.

Because he won't!

It was in such a noisy environment that Bizzie returned to the classroom.

Seeing the excited and indignant looks of his classmates, Bi Qi subconsciously shrunk his neck.

If you let the students know that because of him, Mr. Gu's standard for the next question will be the same as this time, then you will ...... I'm afraid it's going to be torn apart.

Bi Qi cautiously returned to his seat, took an A4 piece of paper, turned to Ma Zhixuan behind him and said, "Ma Zhixuan, the freshly baked math answers, don't read them." ”

Ma Zhixuan's eyes, who were lowering his head, lit up.

Bi Qi laid the answer horizontally on the table, and the two of them put their heads together, looking at each other.

"It turns out that this place does this, and you can get the answer by converting this and this formula, why didn't I think of it at the time!"

"Ma Zhixuan, look at this, the teacher here uses the transformation formula of the proportional series, and the answer can be calculated in just a few steps, our method is too complicated. ”

"Also, in the quadratic formula, only k-1 is found, so it will obviously be much easier to calculate. ”

Both of them can be regarded as two of the people with the highest level of mathematics in the entire third year of high school, so they are naturally very knowledgeable.

Gu Lu gave them this answer, and after they read it, their hearts were already full of horror.

The solution in the answer is the kind of problem that can be solved in one step, and it will never take two steps to solve. What's more, the content used is not over-the-top at all.

All are formulas and theorems that are the foundation of high school mathematics.

"Teacher Gu, it's too powerful!" Ma Zhixuan muttered to himself.

…………

Sunday.

Gu Lu came to work as usual.

As soon as I pushed open the office door, I saw Teacher Sun Ya sitting at the door, with round legs wrapped in stockings.

"Teacher Gu, you're here!" Sun Ya got up, tilted her head and smiled.

Gu Lu was stunned, "Teacher Sun, didn't you have a class today?"

"The school doesn't have a rule that says you can't come to work if you don't have classes on weekends. Sun Ya carried the food box and followed Gu Lu to the desk.

She wouldn't tell Gu Lu that she came to school specifically to feed Gu Lu.

Sun Ya put the food box on the table and opened it carefully, "Teacher Gu, this time I not only brought you glutinous rice balls, but also mung bean cakes, you have to try them well." ”

Seeing Gu Lu eating the dessert she had carefully prepared one bite at a time, Sun Ya looked satisfied.

"By the way, Mr. Gu, I've been learning to make cheesecake recently, can I bring it to you when I learn it?"

Looking at Sun Ya's expectant gaze, Gu Lu hesitated for a moment and nodded lightly in agreement.

"Hiccup~~"

After eating the dessert brought by Sun Ya, Gu Lu covered his mouth and burped.

It seems that he can't eat breakfast in the future, and the desserts that Sun Ya brings every day are enough for him to fill his stomach.

Seeing that the feeding was finished, Sun Ya left with a satisfied face with a small food box.

At this time, Teacher Zhou Haihong came over with an expressionless face, and after seeing Sun Ya close the door and leave, he said to Gu Lu, "Teacher Gu, have you collected yesterday's test papers?"

"Ah, that's it. Gu Lu picked up one of the two stacks of test papers on the table and handed it to Zhou Haihong, "Teacher Zhou, this is your class." ”

Teacher Zhou nodded, took the test paper and opened it, and swept it down with his eyes casually, but as time went by, his brows became more and more wrinkled!
