"We've met."

Opposite Ouyang was a thin man, about 40 years old, although he said that he had met Ouyang, but Ouyang had no impression of him.

Seeing that Ouyang was stunned, the other party reminded again: "Think again!" When taking the college entrance examination for mathematics, is there a candidate who is making trouble in the examination room! ”

Ouyang suddenly realized!

"Y-You're the tour teacher!?"

Ouyang finally recognized the other party, he had no idea about the appearance of the inspection teacher, but the strong strength shown by the other party at that time made Ouyang remember it vividly!

A candidate who is so tall was actually defeated in an understatement, this is the power of a scholar!

"Ouyang, hello, my name is Meng Jiang, and I am a teacher at Yuzhou University."

Meng Jiang politely stretched out his hand to Ouyang, and Ouyang also shook hands with the other party warmly.

After shaking hands, Meng Jiang suddenly said, "The library is closed, let's talk in another place!" ”

Ouyang realized that it was not too early, and he was so focused on the calculation that he even forgot the passage of time......

"Why didn't anyone remind me when it was closed?"

Ouyang asked strangely, and Meng Jiang lit up the key in his hand.

"It's too confusing to disturb the students who are concentrating, right?"

With that, Meng Jiang left the library with Ouyang.

The two came to Meng Jiang's residence, which was different from the student dormitory, the room in the teacher's dormitory was much more spacious, and in this dormitory, in addition to the bedroom, there was also a study.

Ouyang was very interested in the collection of books in the study, but he would not rush to it without the consent of Teacher Meng Jiang.

Teacher Meng saw through Ouyang's thoughts at a glance and said, "You can borrow the books here at any time, as long as you ask for my consent." ”

"Thank you."

Ouyang nodded, and looked around the study to see if there were any books he liked, but unfortunately, Meng Jiang's private collection of books was similar to the library's collection, all of which were some basic teaching books, but there were no books that recorded various equations and calculation methods.

Ouyang was about to take out a book to read, when Meng Jiang suddenly said: "Although I had an impression of you during the college entrance examination, I really knew you as a person after the start of school." ”

“……”

Ouyang turned his head silently, and at this time, there was a hint of mockery in the expression on Teacher Meng's face.

Meng Jiang didn't shy away from it, and teased: "You and Teacher Jian Wenping talked back?" ”

The matter between himself and Teacher Jian, Teacher Meng Jiang actually used the word "backmouth" to describe it, which made Ouyang a little unhappy.

"I didn't talk back to him, I just told the truth!"

Seeing Ouyang trying his best to refute, Meng Jiang smiled slightly.

"Don't worry, I don't mean to blame you, in a sense, I'm quite supportive of your actions!"

"Support?"

Teacher Meng's position, Ouyang can't grasp at this time, but judging from the fact that he invited himself to his bedroom, he shouldn't have bad intentions.

Seeing that Ouyang was a little hesitant, Meng Jiang continued: "In fact, some of Mr. Jian's behaviors, I can't stand it as a colleague, in order to make money, he highly recommends Mr. Shi Fengshou's "Speed Algorithm", although it can also help students, but in general, it does more harm than good!" ”

"More harm than good? How do you say this? ”

Ouyang asked strangely, and Meng Jiang patiently explained to Ouyang.

"Ouyang, in fact, you have also discovered that it is very difficult for ordinary people to achieve a calculation speed of 10 times per second, so Mr. Jian will provide students with a method of quick calculation, although it can make many students step into the threshold of admission in a short period of time, but this is a kind of quick success, when the 'speed algorithm' reaches a sufficient calculation speed, this scholar can not calculate the equation at all, because his foundation is not solid, and in the end he has to make up the foundation."

"I see."

Ouyang finally understood what Teacher Meng Jiang meant, that is to say, for a scholar, the foundation is very important.

"Not only scholars, but even some bachelors and masters, if they have gradually grown up through speed algorithms, then when their strength reaches that height, they gradually find that the strength improved by speed algorithms is watery, so they also need to start learning basic calculations again."

As he spoke, Meng Jiang took out a pen from the drawer and handed it to Ouyang.

"...... this?"

This pen is very exquisite, Ouyang was a little surprised, could it be that Mr. Meng wants to give this pen to himself?

"This is an imitation of [Gauss's Pen], although it is only an imitation, it is also a one-star academic treasure, which should help your calculation progress!"

"Xuebao??"

Ouyang was overjoyed, Teacher Meng Jiang, whom he had just met, actually gave himself a learning treasure, even if it was a one-star learning treasure, in this world, it was already a windfall.

"I can't take such a valuable thing!"

Ouyang handed back the [Gauss's Pen (Imitation)] to Meng Jiang, but Mr. Meng resolutely refused to accept it.

"The Xuebao given to you, you just put it away, the one-star Xuebao is not particularly valuable, if you don't want it again, I will kick you out of me!"

Seeing that Teacher Meng was so stubborn, Ouyang could only put away the [Gauss's Pen (Imitation)], and then Meng Jiang handed him a notebook.

Ouyang opened the notebook and saw that on the first page of the notebook, an algebraic formula was written: C=2πr!

It was the way to calculate the circumference of a circle, and for Ouyang, this was the first time in his life that he came into contact with real equations.

The so-called equation is very precious in the world of scholars, consisting of "algebraic formulas" and "algorithmic rules", of which "algebraic formulas" are very simple, while "algorithms" are very complex, similar to the external and internal skills in traditional martial arts.

Since it is recorded in a notebook, there is naturally an algorithm of equations in it, but Ouyang is still a little different, and Mr. Meng Jiang really wants to give this equation to himself?

"Mr. Meng, is this equation for me?"

"Yes, because it's a very basic equation, it shouldn't be difficult for you to calculate it now."

"However, there is no merit and no ......"

Ouyang was still a little hesitant, but Teacher Meng Jiang hated Ouyang's attitude.

"What 'reactive and unrelenting'? Do you think I sent you the equation because I had a picture? Tell you, if you don't calculate the equation of the circumference of the circle well, I won't spare you! From today onwards, you will live in my dormitory, and I will not let you out if you are proficient in calculating this equation honestly, and I will not let you out until you are proficient! ”

Meng Jiang's words were very serious, and Ouyang could only succumb to the other party and began to seriously calculate the equation for the circumference of the circle.
