"Brother Lang...... Can I read all of this? ”

Fang Chao looked at Shen Lang's subject, his heart was full of surging passion, he fell into a state of thought blockage for a while after encountering the Zhang Lanlan incident in a short period of time, and at this time he desperately wanted to empty himself or improve his mathematical level, so as to break the vacancy period of this period.

The arrival of Shen Lang and the second-order operation of linear algebra brought Fang Chao into a new world.

It took him three hours to see this.

"I said, do you kid want to be so serious? This roast duck is cooked hot for you, and now it's cold again......"

Shen Lang interrupted Fang Chao angrily, this kid was born for mathematics, and as soon as he entered the field of this aspect, he was completely carried away, which is a good thing for the mathematics world, but not a good thing for men.

He, Shen Lang, can do both math and pickle girls, but Fang Chao is still young, so he has to show him the way.

"Ah...... Oh...... I'm sorry, I'm sorry, Brother Lang, I'm ...... Hey, is it already so dark? ”

Fang Chao glanced at the sky and found that it was completely dark, and it was still very bright before they went out......

"We arrived at the hotel at five o'clock, and now it's almost nine o'clock, do you think it won't be dark this day? If this doesn't wake you up again, are you ready to see tomorrow? ”

"No, no, how can this be?"

Shen Lang smiled, "I don't blame you, why do you keep saying I'm sorry?" When I followed Professor Lin, Professor Lin often forgot to sleep and eat, you are still good, sometimes the professor who falls into research, it is useless for you to argue, and even if you really interrupt his train of thought, he will directly scold you, this person who has entered the state, it is like entering the climax, you have to calm him down, it is difficult, and he is not a eunuch......"

Fang Chao: "......"

Fang Chao found that in front of Shen Lang, no matter how much he said, there was no way to compare with Shen Lang, the other party had the charm of a mature man, and more importantly, he couldn't compare with Sao at all.

It's an innate commotion that's too hard to imitate.

"Are you going back in the evening or are you going to stay with me?"

"Here!"

Fang Chao replied almost without thinking, originally thinking about going home at night, but now it seemed that he could only stay in the hotel where Shen Lang was staying. The second-order operation of constant algebra that Professor Lin and Shen Lang and his party jointly studied was too attractive and deadly enough for Fang Chao, like a poisonous perfume, and he was addicted to it.

Shen Lang's time in Rongcheng is only about ten days, and after this time, he will return to Shangjing, so during this time, he will discuss some academic issues with Shen Lang as much as possible.

"Okay, then you report to your family first, otherwise if you don't go home for a few days, your family still thinks something happened to you, maybe they will call the police."

"Okay."

At that moment, Fang Chao dialed Zheng Meiling's phone and reported the news of not going home, Zheng Meiling quickly agreed, and told Fang Chao to pay attention to safety, also pay attention to eating, don't study too hard, and asked by the way if you want to bring you a few changes of clothes, it is impossible to always wear the same clothes, it is impossible to wear the same clothes for ten days in the whole summer, right?

"Okay, thank you, Mom, I'll send you the address on WeChat, and you can send it whenever you want."

"Hmm."

"If mom is fine, I'll hang up first."

"Hmm."

"Bye-bye."

"Bye."

Hung up the phone, Shen Lang continued, "I also ordered takeout, I won't go out to eat today, I will have a meeting of the Mathematics Society in the next three days, you will stay in the hotel alone, if you are bored, go out by yourself, if you have any questions, you can also ask me for advice at any time." ”

Fang Chao nodded, "Okay." ”

Early the next morning, at nine o'clock in the morning, Zheng Meiling sent a few clothes to Fang Chao, and then glanced at the hotel room, and then ordered a few words, nothing more than not to make trouble for others, and don't be too obsessed with studying, look at the dark circles on your eyes, pandas are not as black as you, let Fang Chao go and rest early.

Shen Lang was still sleeping, and the door of his room was closed, so Zheng Meiling didn't deliberately bother anymore, but chose to leave, and when she left, she told Fang Chaodao to call her mother if she had anything.

"Got it, Mom, you go back first, otherwise I'm afraid that if you continue to talk about it, Brother Shen Lang will wake up."

"Well, then I'm leaving."

"Be careful on the road, Mom."

"Got it, let's go."

……

In the next three days, Fang Chao was completely immersed in linear algebra.

As for Shen Lang, in these three days, he only stayed in the hotel for one night, usually, most of him didn't come back, but he sent a picture of a beautiful woman two or three hours before he didn't come back, of course, the background is possible anywhere, bars, cafes, etc., but wherever there are mature beauties, there will inevitably be Shen Lang's figure.

After sending the photo, Shen Lang had no follow-up, but Fang Chao knew the follow-up plot, he didn't bother Shen Lang and gave him absolute freedom.

On the fifth day, perhaps a little tired, Shen Lang took the initiative to chat with Fang Chao, cultivated his spiritual power, and recovered his energy at the same time.

"Chao'er, how is it? Did you learn anything? ”

"Brother Lang, I don't know how to say it, I just think you are really good, how did you think of using second-order operations to solve constant algebra?"

When Shen Lang heard this, the expression on his face finally became serious, and when it came to this aspect, there was little hippie smile on his face, "No way, the domestic linear algebra textbooks are basically not very good, and even with the development of science and technology, many calculations can be directly calculated on the computer, and even in most cases, it is not of much significance to calculate the product of the matrix and the rank of the matrix, the important thing is the principle of calculation......

The most important concepts in linear algebra, linear space and linear transformation, are very helpful for understanding algebra and even high-level mathematics, so my professor and I thought of this topic and conducted special research, but it is still in the initial stage, but who understands that the real charm of mathematics is far from being calculated by computers......"
