The system asked me to be a teacher

Chapter 10 Compete who is the most troublesome
Seeing that the students were getting more and more noisy, Confucius and Mencius quickly stopped them: "Okay, it's class time now, just sit down for me. If anyone wants to make a fuss again, the teacher will punish him to do the problems."

Confucius and Mencius underestimated how mischievous these students were, and another boy said: "Teacher, I am afraid of everything, but I am not afraid of doing problems. Punish me as much as you want!"

Confucius and Mencius walked up to him slowly, and said calmly, "Tell me your name!"

"Teacher, I don't change my name when I walk or sit or change my surname, so does Zhen Tiehan!"

"Good name, student Zhen Tiehan, have you thought of it?"

"Of course, but teacher, my family is poor and I can't afford the exercise book, so I will do as many exercises as you want, but there is a premise that you must take it now. I am very busy. , don’t wait until the expiration date!”

"Really?"

Seeing that Confucius and Mencius still didn't change their expressions, Zhen Tiehan couldn't help being a little hypocritical, but he still insisted: "It must be true."

Confucius and Mencius didn't speak, and pretended to take out his left hand from his bosom, and a four-finger-thick book [10-year must-do questions—Second Year Mathematics] appeared in his hand.

He threw the book on the other side's table: "I'll give you three days to finish it."

"Ah, teacher, this..." Zhen Tiehan was stunned. He saw that Kongmeng entered the classroom empty-handed, so he dared to say what he just said.

Who would have thought that the teacher would put the exercise set in his arms?
This is too perverted!
But before the performance of Confucius and Mencius was over, he touched his back again, and another book [10-year must-do questions—Second Year English] reappeared.

"There is still this book, and I will add two more days to your time."

Then Confucius and Mencius continued to take out Chinese from the left cuff, physics from the right cuff, chemistry from the left trouser leg, and biology from the right trouser leg.

Six books were piled on the desk to form a thick stack.

Kong Meng said with a smile: "My family is poorer than yours, and I can't even afford a handbag, so I can only carry one by one on my body, so I'm sorry.

Also, these books are rare copies that the teacher found after wasting years of hard work. They are very precious. You need to copy them out one by one, and then return the original books to me. "

Zhiyuan Middle School equips each class with a printer, which is very convenient.

Zhen Tiehan's face turned green: "Teacher, can't I be wrong? Please change the punishment. I am a little dizzy after seeing so many questions."

Kong Meng patted him on the shoulder: "Didn't you just say that you like doing problems the most? Classmate Zhen, as the most upstanding and iron-blooded man in our class, he pretends to be coercive in public, and you have to finish it with tears in your eyes!"

"...Okay! I won't do anything in the future, just do the questions." Zhen Tiehan gritted his teeth and said, "Grandma, I'm unlucky because of this bad name."

The other students burst out laughing instantly, the schadenfreude inside couldn't be concealed no matter what.

His tablemate smiled the happiest: "Tie Han, I suggest you change it to a real sissy, so you don't have to do the questions."

Kong Meng looked at this guy with pimples all over his face, and said to Zhen Tiehan, "Make two copies later, and give him one too."

Zhen Tiehan, who originally wanted to quarrel with his deskmate, immediately laughed out loud when he heard the words: "Good teacher, I will definitely supervise him from beginning to end, and not miss a single question."

His deskmate didn't expect that disaster would come from the sky, so he slapped himself on the mouth angrily, which elicited roars of laughter again, and the classroom was filled with a happy atmosphere.

In order to avoid the fear of being dominated by the super-thick exercise set, the other students laughed and quickly calmed down.

They took out their textbooks and lowered their heads. As for whether they were really reading, Confucius and Mencius didn't know.

But he was still shocked, because at least it meant that the attitudes of these students had changed. You must know that they used to just walk away without saying a word.

Five minutes later, another man named Wang Tong who was sitting in the second row suddenly raised his hand: "Teacher, I'm not making a fuss, it's just that the mathematics knowledge in high school is very difficult. No one taught me, so I can't understand it at all!"

The other students immediately raised their heads in high spirits. Of course they were not studying just now, but were thinking about how to provoke Confucius and Mencius again without hurting themselves. Unexpectedly, Brother Tong took the lead.

Wang Tong is the strongest student in class 1 of the second year of high school. Not only is he smart, but he also likes to make decisions before taking action. What others can't handle is all at the last moment.

For example, this time, under the banner of learning, Wang Tong asked sharp questions. As long as Confucius and Mencius couldn't answer, they could take the initiative again like they did with other teachers.

Of course, Confucius and Mencius are different from other teachers. Showing off at that time will not only allow him to do business for the school, but also allow him to accept his own feelings, so that he will not make trouble every day. It is the best of both worlds.

Kong Meng said lightly: "How can you not, show me to see?"

Huh?Isn't Confucius and Mencius a Chinese teacher?Does he know math?Everyone was a little shocked.

Wang Tong was still confident, and he quickly ran to Confucius and Mencius with the book in his hand: "Teacher, it's this question, and I can't do it after thinking about it for a long time."

Confucius and Mencius took a look, and saw that the content of the question was as follows: There are 28 points in a certain space, and any 4 of them are not in the same plane. Connect these 28 points in pairs, and find out how many pairs of straight lines with different planes can be formed in total. ?
After reading the question twice, Confucius and Mencius' eyelids also jumped twice. This question seems very complicated...

He asked: "You haven't learned permutations and combinations yet, have you? Questions like this that involve a lot of data are difficult to solve without the basis of permutations and combinations."

Wang Tong said: "Teacher, I have already taught myself the knowledge of permutations and combinations."

"Really?" Kong Meng couldn't help but look at this guy with admiration, because in the roster of the sophomore (1) class he knew, Wang Tong belonged to the thorns among the thorns.

"Then let me test you. There are 2 boys and 3 girls, a total of 5 students standing in a row, and only 3 of the 2 girls are adjacent to each other. How many ways are there?"

Wang Tong thought for a while, picked up a pen and drew a few times on the straw paper, and said: "72 kinds!"

Confucius and Mencius cheered up: "Oh, not bad, can you tell me how you solved it?"

Wang Tong said proudly: "It's very simple. For this question, two girls who must stand together can be regarded as a whole. First, the girls are all arranged, and then randomly inserted into 2 of the 2 vacancies formed by the two boys. One, just calculate and solve.”

Confucius and Mencius couldn't help giving a thumbs up: "Amazing!"

His praise was absolutely sincere, because he found this question by accident when he was flipping through a math book after he knew that there was no math teacher in Class 1 of Senior Secondary School.

Wang Tong didn't care about the praise of Confucius and Mencius, but said: "Teacher, the question I asked just now..."

"You said this, if you want to find the logarithm of straight lines with different planes, first ask how many straight lines there are..."

While talking, Kong Meng paused, because he found that there seemed to be some problems with his train of thought.

After all, I am not a mathematics major. Although my grades were not bad in school, after so many years, most of them have been forgotten.

Just as he was sighing, he heard two beeps, it's the system!
——Congratulations to the host for successfully activating [Middle School Mathematics Project]

Huh?what's the situation?It seems that I didn't teach math class?

Is it okay to discuss issues with Wang Tong?
Before he had time to think about it, a lot of knowledge suddenly flooded into his mind, and Confucius felt as if he had suddenly returned to the moment before the college entrance examination.

The line-by-line formulas are so clear, and each method is so easy. The important and difficult points of each module and the traps of various test questions are like snowflakes falling into the fingertips, and they disappear with just a light rub.

Seeing that Kong Meng was frowning, Wang Tong couldn't help but said, "Teacher, can you know this question? If not, I'll go back and ask my private teacher."

The other students also looked over one after another. What Wang Tong said about the private teacher was of course just an excuse for absenteeism.

He has used this method before, and every time he uses some difficult problems to embarrass the teacher, and when he succeeds, he will leave with an excuse.

The teacher is a human being, not a god. Under the bombardment of a large number of problems, there will always be a day when he cannot solve them.

A teacher with a good temper may just write down the account and calculate it later. If he encounters a bad tempered teacher, he will simply not come.
