Qiao Yu's indifferent attitude almost made Lan Jie get stuck.
Although he was so resistant yesterday, he is able to get everything he wants today? How can this child's mentality change so quickly?
Well, I can only say that this little guy is really serious about making money.
"Okay, as long as you are willing to quit smoking. The school's Olympiad training class is every Monday, Wednesday, and Friday from 4 to 5:30 pm. For the next month, you don't have to attend the third class in the afternoon. Before 4 o'clock
Just go to Electronic Classroom 302 in this building. Training classes during the holidays will be notified separately at that time."
After calming down, Lan Jie began to explain in earnest.
Qiao Yu nodded, and then took the initiative to ask: "Just three classes a week? What books should I read on a daily basis? I only have one "Introduction to Riemannian Geometry" at home."
"Riemannian geometry? What are you looking at that thing for?" Lan Jie was stunned and asked.
"Wouldn't self-study help in the competition?" Qiao Yu asked rhetorically.
Lang Jie swallowed, then shook his head decisively and emphasized: "No, it won't help at all."
"Oh, that's good." Qiao Yu also breathed a sigh of relief, which showed that the Olympiad questions seemed really simple.
"Can you understand that book?" Lan Jie couldn't help but ask.
To be honest, Lang Jie did come into contact with the content of Riemannian geometry when he was studying for a master's degree, but he only had a general understanding of it. After all, what he was learning did not require a very in-depth understanding of these things.
"I don't fully understand." Qiao Yu shook his head honestly and said, "The previous discussion on manifolds and tangent spaces was okay, but when it comes to the Riemannian metric, connection and curvature, it feels a bit difficult."
"Have you taught yourself calculus, linear algebra and topology?" Lan Jie was surprised. This was something he had not mastered.
If you want to understand the basics of Riemannian geometric manifolds, you must study these subjects systematically. Otherwise, it is impossible to understand concepts such as smooth manifolds, tangent spaces, vector fields, etc.
In the same way, if you have not been exposed to linear algebra and topology, it is impossible to understand concepts such as vector space, linear mapping, basis, coordinate system, open set, closed set, continuous mapping, etc.
If you don't understand these, you won't be able to understand the structure of the manifold in the book.
Qiao Yu nodded: "I have watched a lot of class videos scattered on the Internet. I also borrowed a few books from the library and read through them."
Lan Jie shook his head and said seriously: "The content of the Mathematics Olympiad geometry test is mainly plane geometry, solid geometry, involving Euclidean geometry and trigonometric geometry. In fact, all Olympiad questions will not include college mathematics content.
.But in your current situation..."
Having said this, Lan Jie hesitated for a moment, then bent down and opened the cabinet under the desk. In a moment, he pulled out three books and handed them over.
"If you have a lot of spare time and want to study advanced mathematics, you can read these two books systematically first. If you don't understand anything, you can ask me."
Qiao Yu took the book from Lan Jie and read the title carefully.
One is "Principles of Mathematical Analysis Volume 1", the author is Feichingolz, the second is also "Principles of Mathematical Analysis", but the author is Ludin, and the other is "Introduction to Algebra and Number Theory" The author's last name is
Feng Keqin.
Then Qiao Yu handed back "Principles of Mathematical Analysis Volume 1" by Feihejin Goltz: "Thank you, Teacher Lan, but I won't need this one. I have studied his mathematical analysis by myself."
"Have you studied on your own?" Lan Jie was a little surprised, but he didn't say much. He took the book back and said, "Then you might want to read Ludin's book. There are ways in which the two books can complement each other."
"Okay, Teacher Lan."
Lan Jie curled his lips, suddenly thought of something, and said: "By the way, I don't know much about your advanced mathematics mastery. You can learn about the global mathematics competition organized by Little Libaba.
If you can successfully enter the finals and achieve good results, there will also be bonuses. The gold award is US$30,000, and the excellence award is US$2,000. There is also a practice competition on the official website, which is convenient for those who are familiar with the answering system. You can also download previous questions.
Maybe test your math skills."
"The test award is 30,000 US dollars. Isn't that a bonus of more than 200,000 RMB? Is there any tax? Is there any handling fee when converting to RMB?" Qiao Yu asked three questions in an instant.
Lan Jie was startled for a moment, and then he saw the twinkling light in Qiao Yu's eyes.
Really, he just said it casually. After all, the topic has already been discussed here. But I didn't expect this guy to be so sensitive to the bonus number. Especially when people focus on whether he can participate in the competition, this guy actually thought about whether he should participate in the competition.
Pay taxes…
"Of course you have to pay tax on the bonus. But you don't have any other income. If you really get the bonus, your mother should be able to apply for a tax refund in March next year. As for the US dollars, it's because this is a global competition. Converting it to RMB is about
There is no handling fee.”
Lang Jie explained.
I didn't pay too much attention to it because he had never won an award, so I really didn't know.
"More than two hundred thousand." Qiao Yu sighed.
It would be great if he could win a gold medal. Earning this money would instantly increase his family assets by 200%. At least he could participate in the competition with peace of mind.
Lan Jie looked at Qiao Yu warily and warned: "Do you understand what the Global Mathematics Competition means? Those who are competing with you are not your peers. There are masters and Ph.D.s from universities like Huaqing and Yanbei in China.
There are also top students from foreign universities such as Cambridge and Harvard.
And although you can register to participate in the preliminary round, and the competition is online, there are strict proctoring measures to enter the finals. So you must not think of any cheating methods, it will be useless even if you win the prize."
No wonder Lan Jie was worried.
He could feel Qiao Yu's persistence in making money.
That's all. The key is that this kid still has an evil spirit.
Lan Jie had no doubt that if Qiao Yuzhen found a way to cheat, he would definitely do it for the bonus without hesitation.
"Don't worry, Teacher Lan, I know it well. To be honest, I have never cheated on an exam since I was a child." Qiao Yu answered.
To be honest, Lan Jie is still not reassured. He believes that Qiao Yu has not cheated in exams since he was a child, at least in junior high school. After all, there is not much room for improvement in his performance. But after all, there are no bonuses in those exams.
I still wanted to say something, but thinking that Qiao Yu was only a fifteen-year-old child, at the age of rebelliousness, I still refrained from saying anything.
It aroused a rebellious mentality, and it would be bad if something happened without incident. So Lan Jie simply changed the topic to the high school entrance examination: "I heard from your teacher Yuan, do you plan to take the high school entrance examination normally?"
Qiao Yu nodded and said, "Yes."
"Are you confident?" Lan Jie asked.
"At least I think it's okay to cross the Pugao Line." Qiao Yu said conservatively.
Lan Jie nodded noncommittally, and then said calmly: "Qiao Yu, you have talent. As long as you are willing to show it, I believe that no matter where you go in the future, you will be discovered. But I still hope that you can stay in Tieyi
middle.
This is not only for your consideration, but I also have selfish motives. But one thing is that only in Tieyi Middle School can I ensure that all the promises I made to you are fulfilled. To be honest, based on your situation, I personally think that it is still risky to take the high school entrance examination this year.
Yes, are you sure you must take the high school entrance examination this year?"
Qiao Yu raised his head and smiled confidently, and said: "Well, I will take the mock test seriously next time. If the score is not enough to reach 620 after adding the previous results of physical education and birthplace, I will follow your arrangements.
"
Lan Jie hesitated for a moment and said, "Okay... then."
"Then I'll go first?"
"Well, don't forget to go to classroom 302 at 4pm tomorrow."
"Okay, goodbye teacher."
"Wait, add WeChat."
"Um, I'm sorry, Teacher Lan, I didn't bring my mobile phone with me today."
At this moment, Qiao Yu thought of Xia Keke. Look, Xiao Nizi is doing bad things.
"Ah?" Lan Jie glanced at Qiao Yu: "Okay, 13XXXXXXXX, you can write down my phone number and add me when you get home."
