Xueba digs a hole and waits for you to jump

Chapter 371 230. Look, This Is My Boyfriend
The next day, the sales office of Yuyu Yayun was very lively early in the morning.

Mrs. Jin patted the table with an angry look on her face, "How could it be gone? Didn't there be Jiudong yesterday! What do you mean by that?! Are you deceiving customers!"

The ladies in the sales office also showed embarrassment and smiled, but this is not their problem. It was the sales manager who said early in the morning that all the villas had signed contracts and would no longer sell them. There is no way to get another set to buy for this aunt!
"Didn't we say we wanted a set last night? We still had it back then, why did it disappear after one night?"

Jin Minshu's complexion was not good either, thanks to her imagining the scene of running into Guan Xu by the lake last night and sparking sparks, she woke up early today, but when she arrived, she found that the house was gone!
"I'm sorry, two ladies, because you are only verbal wishes, we have a deposit to sign the contract."

One of the female salesmen brought two cups of coffee. Those who can come here to buy a house are either rich or expensive. They can't afford to offend these small salesmen, but they are polite, and Mrs. Jin is not so good. He turned over the coffee, pointed at the saleswoman's nose, and was aggressive.

"I don't care! You guys have to get me a set today! Otherwise, I won't leave! I'll complain to your manager and fire you all!"

Mrs. Jin swaggered and sat in the sales center, as if she would not leave unless you gave me an answer. Jin Minshu also acted unreasonable, forcing the staff to call the police.

As a result, of course the mother and daughter of the Jin family were taken away by the police, and the villa must have lost their share.

Nine Days Studio.

"Brother Xu, it's done. This is the purchase contract for Yuyu Yayun's ten villas."

Shen Jin neatly placed a large stack of folders with the Yuyu Yayun logo on Guan Xu's desk.

That's right!Uncle Guan is the one who bought all the remaining villas in Yuyu Yayun. There are too many ways to prevent the Jin family from living in this community. This is the simplest and rude one. Isn’t it just a deposit, which is not bad for Uncle Guan. Money can also be regarded as an investment.

"Well, you can change hands if you see fit."

"Okay!" Shen Jin smiled like a cauliflower, "Brother Xu, is there any commission for the sale?"

Guan Xu knew that Shen Jin was going to say this, "Three percent of the price difference."

"Brother Xu, don't worry, I will definitely earn you [-]% for each building!"

If Shen Jin laughed like a cauliflower just now, then now he laughs like a rotten cauliflower, showing his teeth. You must know that according to the current housing prices in city A, such a house can be sold for 30 million yuan, right? The problem is that it is not impossible to earn 100 million if you negotiate well. Calculated at [-]%, it is trivial for Shen Jin to work hard to earn more than [-] extra money for himself.

Guan Xu didn't look at Shen Jin's money-obsessed face, "By the way, help me find two more interior designers, and make an appointment tomorrow or the day after tomorrow."

"No problem, European style, Chinese style, ancient court, Baroque style, all for you!"

Guan Xu raised his eyes, but Shen Jin didn't respond. This guy really feels uncomfortable all day without talking. Is it a decoration or a hodgepodge? !
"Brother Xu, is there anything else? If not, I'm going to prepare meeting materials."

Guan Xu waved his hand, and Shen Jin walked out of the office with a gait like twisting yangko. Thinking about those Mao grandpas, Shen Jin felt that life was full of hope.

Although Shen Jin talked a lot, he was more reliable in handling things. The two designers he found for Guan Xu were good at the overall structure, and the other was good at grasping the details. The most important thing was that the two of them were good friends in life. Generally, they have a very eccentric temper. If two people are friends, it will be easier to communicate when actually drawing pictures.

Because he wanted to decorate according to Tang Hongdou's preferences, Guan Xu deliberately brought Tang Hongdou with him when he met the designer. No matter what the two asked, Tang Hongdou would answer, as if the official was accompanying him. There are no comments, only supplements, and I absolutely agree with Tang Hongdou's idea.

Architecture is a bit more scientific. Tang Hongdou couldn't understand some temporary sketches drawn by the designer, but she still understood it very carefully, with a serious and meticulous look.

Guan Xu couldn't take his eyes off Tang Hongdou. When he said he wanted to buy a house, Zhou Shuilin also said that he was extravagant and wasteful. But now it seems that this is really a wise choice, because the home designed and built by two people will be more warm. a feeling of.

"No problem, Miss Tang, we all understand what you mean. We will draw a sketch first in a month, and make a model by the way. Then you can see if there is anything that needs to be changed, is that okay?"

When Tang Hongdou heard that there was still a model, she felt that she was saved, and nodded happily to thank her.

The two designers left because they still had something to do. Guan Xu thought that this kind of matter would take a long time to discuss, so the whole afternoon was free, and he happened to be able to accompany Tang Hongdou to class.

Because he was afraid that Guan Xu's appearance would cause riots in the classroom, Tang Hongdou deliberately entered the classroom through the back door with the bell ringing, and sat in the last row. This class is linear algebra, and Tang Hongdou's most troublesome class this semester is none of them. .

Sure enough, Tang Hongdou had only listened to it for 5 minutes before he began to clench his chin, frown, and nibble on his pen with a dazed expression.

Guan Xu was originally playing with his mobile phone with his head down, but turned his head to look at Tang Hongdou's little expression and was amused, so he stopped playing with his mobile phone. He took Tang Hongdou's textbook, glanced at what he was talking about, and then looked at the teacher's PPT .

"You can try to use Cramer's law for the question the professor said, please see page 24—"

Guan Xu pointed to a sample problem in the textbook. Tang Hongdou looked at it twice, and her brows became more and more wrinkled. I'm sorry, but she hasn't even grasped the method taught by the teacher. It's better to let her not eat in the afternoon if she understands it thoroughly.

Seeing that Tang Hongdou couldn't see the hidden relationship between the two topics, Guan Xu didn't laugh at her, picked up her pen with colorful patterns, tore off a piece of draft paper, and started to calculate——

"You see, Cramer's law says that if the coefficient determinant is not equal to zero, then the corresponding system of equations has a unique solution, right?"

As Guan Xu said, he looked at Tang Hongdou's expression, saw her nodding, and then continued, "The question is a matrix of squares. When doing addition operations, we must ensure that the order of A and B with blocks as elements The number must be the same, and the order of each corresponding block must be the same, can this be understood?"

"Uh-huh."

"Okay, now let's find out the inverse matrix of the sub-block in this block matrix, let's see what it is—"

Guan Xu calculated while talking, his handwriting was strong, and he found the inverse matrix of the sub-block without any mistakes. Once the inverse matrix came out, it was very obvious.

Tang Hongdou patted Guan Xu's shoulder excitedly, "Yes, yes, its inverse matrix is ​​a coefficient determinant! You can use Clem's law!"

"Well, it's not too stupid..."

Guan Xu put down his pen and rubbed Tang Hongdou's little head. Before Tang Hongdou could fart, there was a long voice in front——

"Student, can you explain your method again... I feel that it is simpler than the professor's, but I didn't understand it just now."

"Okay, okay!"

Tang Hongdou readily agreed, picked up the pen and handed it to Guan Xu, but the official didn't answer it, and continued to play with his phone with his head down. Willing, others... He is not very willing.

Tang Hongdou smiled awkwardly, and could only hold a pen and speak by himself, as if it was a review and consolidation. The three people sitting in the front row turned their heads to listen to Tang Hongdou, because this method was indeed very clever. One of the girls After listening to one, I couldn't help clapping my hands, which was especially abrupt in the quiet classroom.

"What are you doing! I've seen you for a long time and don't want to talk about you, but now you want to affect the order of the classroom, it's just too shameful!"

The girl who clapped her hands stood up weakly, "Professor Wang, I'm sorry, there is an easier solution to the problem, I couldn't hold back my excitement..."

"You haven't mastered what I said, what better way can you think of!"

Professor Wang is a well-known old-timer in the school. He is obsessed with the research of mathematical problems. Of course, he is not happy when someone interrupts his passionate lecture.

"But Professor Wang, this method is really simple..."

"You go to the whiteboard and write it out, I want to see, if the class is not good, I can come up with a better way!" Professor Wang slammed the black fountain pen on the podium, "If you can't write it out, you will have to write it down at the end of the semester." You'd better give me a good exam, because you don't have the usual points!"

The girl was a little nervous, but she still walked up to the podium and wrote out the method she just heard from Tang Hongdou. At first, Professor Wang looked disdainful. When the inverse matrix was written, he took off his glasses Come down, get closer, the index finger of the right hand keeps writing something on the palm of the left hand.

"Not bad! Very good!"

Changing the seriousness just now, Professor Wang smiled like a lucky cat, "This idea is very novel, and I can come up with such a method only in my sophomore year. It's pretty good! Study hard and keep working hard!"

The applauding girl breathed a sigh of relief, but she didn't dare to take credit for it. She was thankful that her usual points were not deducted. To be honest, it was Tang Hongdou who came up with it.

Just as Professor Wang was about to boast, Tang Hongdou looked at Chao Guanxu honestly and said that he came up with the idea to solve the problem.

Finally found the real problem solver, Professor Wang walked from the podium to the last row as if seeing a baby, "Young man is very good, what major is he, and how old is he?"

Guan Xu stood up respectfully and politely, "A senior in the School of Finance."

"No wonder it's a senior year, but it's not easy to come up with such a method. You shouldn't need to retake the exam to earn points. Why did you come to my class?"

"I came here with my girlfriend." The official said truthfully.

Immediately, more than 90 pairs of gossiping eyes in the classroom looked over at once. Many people recognized Guan Xu and started whispering. Tang Hongdou had already seen that the classroom was full of female hormones.

There was a trace of unnaturalness on Professor Wang's face. He thought it was because he spoke well that people came to listen to his lectures, but it didn't matter why he came here. He was more interested in how this boy came up with this idea of.

"Can you tell me how you think?"

Guan Xu nodded, "The diagonal values ​​of this question are arithmetic progressions. One coefficient can be extracted in turn, and then the entire matrix can have a coefficient that can be extracted. After extracting the coefficient..."

After reading the calculation method, everyone thought that this problem was very simple, but when Guan Xu shared his ideas, everyone realized that there was too much knowledge connected in series in this method, and the knowledge was used very flexibly to solve the problem. The method is very simple, but the idea is not simple.

"...so the methods for topics like this are common, and they can all be done in this way."

After Guan Xu finished speaking, Professor Wang's eyes lit up. Isn't it like seeing a treasure, this is a treasure!If this idea is proved strictly, maybe it can be used as a theorem, and those international mathematics awards will be won.

"Student, have you written this idea into a paper?"

"No, it's just that when I was learning, I thought of this method in order to make it easier to do."

"It's a pity..." Professor Wang was a little disappointed, "Then are you interested in doing this project with me? I think it's very valuable!"

Guan Xu just opened his mouth to refuse, but Tang Hongdou subconsciously tugged at the corner of his clothes, his small eyes were full of admiration, and the uncle suddenly felt that this proof should be very interesting.

"Okay, then thank you professor."

Hearing Guan Xu's promise, Professor Wang smiled so much that the folds on his face could kill flies, Tang Hongdou smiled proudly, look, this is my man!
