Chapter 18 I Can Do It (asking for monthly ticket)

Qiao Yu's indifferent attitude almost made Lang Jie stuck.

He was so resistant yesterday, but today he can get whatever he wants? How can this child change his mindset 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 held every Monday, Wednesday, and Friday from 302: to : p.m. You don't have to attend the third class in the afternoon for the next month. Just come to the electronic classroom in this building before :. We will notify you separately about the training class during the holidays."

After calming down, Ranger began to explain seriously.

Qiao Yu nodded, and then asked, "Just three classes a week? What books should I read on weekdays? I only have a copy of "Introduction to Riemannian Geometry" at home."

"Riemann geometry? Why are you looking at that thing?" Ranger was stunned and asked.

"Will self-studying this not help with the competition?" Qiao Yu asked back.

Langjie swallowed his saliva, then shook his head decisively and emphasized: "No, not at all."

"Oh, that's good." Qiao Yu also breathed a sigh of relief, which meant that the questions in the Olympiad seemed to be really simple.

"Can you understand that book?" Ranger couldn't help but ask.

To be honest, Ranger did come across Riemannian geometry when he was studying for his master's degree, but he only had a general understanding of it. After all, what he studied did not require a very in-depth understanding of these things.

"I don't fully understand it." Qiao Yu shook his head honestly and said, "The previous discussion on manifolds and tangent spaces was okay, but the content involving Riemannian metrics, connections and curvature feels a bit difficult."

"You also taught yourself calculus, linear algebra and topology?" Ranger was surprised. This was something he didn't understand.

If you want to understand the basics of Riemannian geometry manifolds, you must have studied these subjects systematically. Otherwise, it will be impossible to understand concepts such as smooth manifolds, tangent spaces, vector fields, etc.

Similarly, 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 sets, closed sets, continuous mapping, etc.

Without understanding these, it is impossible to understand the structure of the manifold in the book.

Qiao Yu nodded: "I have watched a lot of class videos on the Internet. I also borrowed a few books from the library and read them."

Langjie shook his head and said seriously: "The content of the geometry test of the Mathematical Olympiad is mainly plane geometry and solid geometry, involving Euclidean geometry and trigonometric geometry. In fact, all Olympiad questions will not contain university mathematics content. But in your current situation..."

Having said that, Ranger hesitated for a moment, but still bent down and opened the cabinet under the desk. After a moment, he took out three books and handed them over.

"If you have a lot of spare time and want to study advanced mathematics, you can first read these three books systematically. If you don't understand something, you can ask me."

Qiao Yu took the book from Lan Jie and looked at the title carefully.

One is "Principles of Mathematical Analysis, Volume 1", written by Fehkingolz, the second is also "Principles of Mathematical Analysis", but the author is Rudin, and the other is "Introduction to Algebra and Number Theory", written by Feng Keqin.

Then Qiao Yu handed back the first volume of Principles of Mathematical Analysis by Fehkin Goltz: "Thank you, Mr. Lan, but I don't need this one. I have already learned this book by myself."

"You've taught yourself?" Lang Jie was a little surprised, but he didn't say much. He took the book back and said, "Then you can probably flip through Ludin's book. Some of the methods in the two books can complement each other."

"Okay, Mr. Lan."

Langjie curled his lips, suddenly thought of something, and said, "By the way, I'm not sure about your mastery of advanced mathematics. You can learn about the global mathematics competition organized by Xiaoli Baba.

If you can successfully enter the finals and get good results, you will also receive a bonus. The gold prize is 30,000 US dollars, and the excellent prize is 2,000 US dollars. There are also practice games on the official website to familiarize yourself with the answering system. You can also download past questions to test your math level.

"A test prize of 30,000 US dollars, isn't that a bonus of more than 200,000 RMB? Do I have to pay taxes? Is there a handling fee for converting it into RMB?" Qiao Yu asked three questions in a row.

Lang Jie was slightly startled, and then he saw the light flashing in Qiao Yu's eyes.

Really, he just said that casually, after all, the topic has already been brought up. I just didn't expect this guy to be so sensitive about the prize money. Especially when everyone is concerned about whether they can participate in the competition, this guy actually thinks about whether he should pay taxes...

"Of course you have to pay taxes on the prize money. But you don't have much other income. If you really get the prize, you should be able to ask your mother to apply for a tax refund in March next year. As for paying in US dollars, it's because this is a global competition, and there probably won't be any handling fees for converting it into RMB." Ranger explained.

I didn't pay too much attention because he has never won any award, so I really don't know.

"More than 200,000." Qiao Yu sighed.

It would be great if he could win a gold medal. With this money, the family assets would instantly increase by 200%. At least he could participate in the competition with peace of mind.

Lang Jie looked at Qiao Yu warily and warned him, "Do you understand what the Global Mathematics Competition means? The people you are competing with are not your peers. There are masters and doctors from universities like Huaqing and Yanbei in China, as well as top students from foreign universities like Cambridge and Harvard.

Although you can participate in the preliminary round by just signing up, and the competition is online, there are strict proctoring measures for the final round. So you must not think of cheating, because it will be useless even if you win the prize. "

No wonder Ranger is worried.

He could feel Qiao Yu's persistence in making money.

That would be fine, but the key point is that this kid still has an evil spirit.

Langjie had no doubt that if Qiao Yu really found a way to cheat, he would do it without hesitation for the bonus.

"Don't worry, Teacher Lan, I know what I'm doing. To be honest, I have never cheated in an exam since I was a child." Qiao Yu replied.

To be honest, Lan Jie was still a little worried. He believed that Qiao Yu had never cheated in exams since he was a child, at least not in junior high school. After all, his grades were not much worse. But after all, there was no bonus for those exams.

I wanted to say something, but when I thought about the fact that Qiao Yu was only a fifteen-year-old boy, at the age of rebellion, I held back and said nothing more.

It aroused the rebellious psychology, and it would be bad if something that was originally fine was caused to cause trouble. So Lan Jie simply changed the topic to the high school entrance examination: "I heard from your teacher Yuan that you plan to take the high school entrance examination normally?"

Qiao Yu nodded and replied, "Yes."

"Are you confident?" Ranjie asked.

"At least I think it's no problem to pass the general high school entrance exam." Qiao Yu said conservatively.

Lang Jie nodded without comment, and then said calmly: "Qiao Yu, you have talent. As long as you are willing to show it, I believe you will be discovered no matter where you go in the future. But I still hope you can stay in Tieyi Middle School.

This is not only for your sake, but I also have selfish motives. But one thing is that only in Tieyi Middle School can I guarantee that all my promises to you will be fulfilled. To be honest, considering your situation, I personally think it is still risky to take the high school entrance examination this year. Are you sure you must take the high school entrance examination this year?"

Qiao Yu raised his head and smiled confidently, saying, "How about this, I will take the next mock exam seriously. If my score is not enough for 620 after adding my previous scores in PE and biology, I will follow your instructions."

Langjie hesitated for a moment and said, "Well... okay."

"Then I'll leave first?"

"Well, don't forget classroom 4 at 302 pm tomorrow."

"Okay, goodbye, teacher."

"Wait, add WeChat."

"Um, sorry, Mr. Lan, I didn't bring my phone today."

At this moment, Qiao Yu thought of Xia Keke. See, it was all the little girl's fault.

"Ah?" Lan Jie glanced at Qiao Yu and said, "Okay, 13XXXXXXXX, write down my phone number and add me when you get home."

"Hey, wait, don't leave so quickly, leave me your phone number."
