dream of red mansion

Chapter 72

"Students have a similar topic to ask sir."

He didn't care about other people's reactions, and continued: "Chickens, ducks and rabbits share the same cage, with a total of 78 legs. Among them, there are nine more rabbits than ducks, and twice as many ducks as chickens. Ask the chickens, ducks and rabbits how many each."

Jia Qing didn't know if Qian Jingrun would understand.This kind of question is obviously not easy to do with the method that Liu Hong said before, but as long as you master the method, it is also a very simple question.

But in any case, it is more complicated than the question he asked.If Qian Jingrun can solve it, he is going to pose a more difficult problem, and today he must save face.

It has been almost five years since I came to this world, and I have also read books for almost five years. I don’t need to worry about acting a bit evil. The word scholar can explain everything!
A classmate who was defending Qian Jingrun got up and said, "Jia Qing, you say such a weird question to make things difficult for Mr. Qian, do you still have the word "respect teacher" in your eyes? Besides, do you know how to solve it?"

Jia Qing didn't even look at him.Respect the teacher?Of course he respects the teacher!But what he respects is a teacher who respects students. Qian Jingrun fined him for standing without saying anything, and he has been listed as a teacher who does not deserve respect.

On the contrary, Qian Jingrun waved his hand indifferently, motioning him to sit down.Then he looked at Jia Qing and said, "Is this also solved with Tianyuan technique?"

Jia Qing said: "I don't know Tianyuan technique, I call it equation system."

Qian Jingrun asked in surprise, "You really know how to understand?"

After hesitating for a while, Qian Jingrun continued: "There are three elements in this question that I don't know. I don't know how to solve it for a while, so I ask classmate Jia for advice..." He made a gesture of asking for advice, and bowed slightly body.

"gentlemen……"

This time Liu Hong also stood up.

Jia Qing was also very surprised. He didn't understand that Jia Qing could have expected it, but he directly admitted and asked Jia Qing for advice, which surprised Jia Qing.Hastily withdrew from the seat, returned the salute with a deeper latitude: "Sir, the students dare not accept it."

Qian Jingrun did hesitate a little before he said it, but he was relieved as soon as he said it.Hearing this, he said: "Since ancient times, those who have reached the top are the first. If you know what I can't, so what if you accept my worship? But if you are talking nonsense, from now on you will stand in my class."

Mother Hippie, you're getting more and more of a threat, aren't you?It seems that the sword will not work...

Just as Jia Qing was about to step forward to write the answer, he turned around again.

"Why, you can't do it again? Then you can move your stool to the back, so as not to block the students behind.

Jia Qing's expression froze when he heard the words, but he still wanted to ask his own question: "Why did you punish me earlier, sir?"

Looking at the doubt in Jia Qing's eyes, Qian Jingrun doubted his own judgment, and asked, "Why do you recite ninety-nine backwards? Did someone teach you that?"

Uh, that's it... no one really taught me!When Jia Jing was teaching Jia Qing, he discovered that Jia Qing knew basic arithmetic. He thought it was taught by Yu Yuanchen, so he never thought about explaining this aspect to Jia Qing. Anyway, arithmetic is not important...

And Yu Yuanchen thought that Jia Jing was teaching Jia Qing in private, so he ignored it...

"Oh, no one taught it, no one taught it, the students thought it would be easier to memorize it this way." Jia Qing turned his head and walked to the front as he spoke.Qian Jingrun was left behind and said "nonsense!"

Afterwards, Jia Qing presented this simple ternary linear equation system in front of this era.Immediately Jia Qing discovered that other people, including Liu Hong, were completely unfamiliar with this.But Qian Jingrun, he can basically understand those equations, but he can't solve them...

After careful questioning, Jia Qing discovered that there are indeed equations in this era, but the means of solving equations are very poor, because there is no concept of unknowns, so Qian Jingrun does not know how to "eliminate elements", but only "straightforward". division"……

This is a warning to Jia Qing, don't pretend to be aggressive everywhere in the future, maybe you will be slapped in the face by an expert.

But Qian Jingrun didn't have the slightest intention to test Jia Qing any more, what a joke, this is a child prodigy, okay?With the arithmetic talent shown by him, he will definitely be able to make great achievements in the subject of arithmetic.

Qian Jingrun is going to cross Jiaqing and enter the school of arithmetic.Therefore, the following class basically became Jia Qing's private exchange meeting with him, and everyone else became decorations...

"Would you like to study arithmetic further? I can recommend you to my teacher. He is ten times better than me in arithmetic. Now that Nanjian is working as a secretary, he will definitely accept you. How about it? Would you like to? "

Seeing that it was time for dinner and school was about to finish, Qian Jingrun said like this.

But Jia Qing would definitely not agree, regardless of whether arithmetic can help him.It is the "master of arithmetic". To put it bluntly, it is not certain who will teach who.However, after more than an hour of communication, his impression of Qian Jingrun was completely changed.So he declined and said, "Thank you, Mr. Qian, for your kindness. It's just that my father ordered the students to sit in the imperial examination. Maybe they don't have much time to study arithmetic."

Originally, the imperial examinations did not test arithmetic. The reason why the two prisons in the north and the south still retain arithmetic is to make the supervisors have more skills. Handicapped.Moreover, the proportion of arithmetic courses in the Imperial College is also the smallest.

Qian Jingrun understood what Jia Qing meant, and he had no ability to change this situation, but he still said: "I will write a letter to the teacher, and you can visit Jiangnan in the future, it will be beneficial."

"Thank you sir."

……

Once the early spring is over, it is mid-spring and February.

The Guozijian February Poetry Meeting will be held on the second day of February.This is a good day, known as the day when the dragon raises its head in ancient times.

Behind the dormitory area of ​​the Guozijian, there is a piece of broken land, which is specially used by the Guozijian for spring outings.At this time, this broken land is naturally green and full of spring.

Especially in the early morning, when the breeze is mixed with drizzle, there are occasional blooming flowers standing in the sunshine of the rising sun.

Walking inside, like a poem goes:

Sometimes it rains at two o'clock three o'clock,
There are ten and five flowers everywhere.

Jia Qing, Xie Guowei, Qi Chengwu and Hou Hu also came here.

Although Hou Hu and Qi Chengwu's literary talents are almost zero, they are willing to join in the fun during this important event of the Imperial College.

The poetry meeting is very casual, as long as you are a student in the prison, you can participate.You just need to write your own work on the placed inkstone and hand it to the gentleman in the viewing pavilion above before the end of Sishi (nine to eleven o'clock).

No questions, no rhyme, no quantity.

The whole morning is free time for free play. In the afternoon, we will focus on reviews and select the top ten best works.

There are about 900 people in the whole Guozijian. Although it is impossible for all of them to participate, it also makes this sloping land of less than [-] acres lively.

"Mr. Jia!"

When Jia Qing and the others looked back, it was Qian Jingrun.So they bowed to him together and said, "I met Mr. Qian."

Afterwards, Jia Qing complained: "Mr. Qian, please don't offend the younger generation. How can a teacher call you Mr. Junior? It's too strange to be heard by others. Just call the younger generation by his name."

Ever since he showed some arithmetic "talent" last time, Qian Jingrun often asked Jia Qing to discuss arithmetic.After going back and forth, Qian Jingrun found that Jia Qing's mind seemed to be filled with treasures, and Buddha could give him endless inspiration.So he began to frantically ask Jia Qing for various questions.

Although Jia Qing could not answer all the answers, he could always come up with unique ideas that he had never heard of.

No, since a few days ago, I no longer call him Classmate Jia when we meet, and call him Mr. Jia directly.

Qian Jingrun ignored him, and said, "Since ancient times, masters have been teachers. If you listen to my class, call me Mr. Qian. I will ask you questions in private, so why not call you Mr.? Don't be bound by vain etiquette." !"
