105. Divine Problem Solving

Since elementary school, it has been studying mathematics for eleven years. Zhou Lele's first test for duck eggs. His confidence in mathematics can be said to have been crushed to pieces. The people who come to the winter camp are so powerful, all of them are at the king level. Compared with these people, Zhou Lele feels that he is an amateur and accidentally runs to the pile of professional players.

Zhou Lele sighed: "Don't laugh, I've said that my math is average."

Li Xuan said honestly: "You said you were not good at math, and I always thought you were modest."

Cao Song nodded: "I'm the same, I see you playing games all the time in the dormitory, looking light and quiet, looking like a god of learning, which makes me very nervous and stressed."

Zhou Lele accepted the reality and smiled bitterly: "Actually, I am good at math. I can get more than 140 in the exams. It's because you are so good at math and the questions are too difficult. I rarely do such perverted difficult problems and have no idea at all. I can't figure out how you can solve them. How can math be so good?"

Li Xuan blinked: "Maybe he talked less?"

Cao Song was stunned for a moment, and the more he thought about it, the more he felt reasonable, and suddenly realized: "Yes, it seems that this is the case. Ou Shen rarely speaks, unlike Zhou Lele, you are talking all day long. No, I have to say less, if you are infected by you, you will be finished."

Zhou Lele:=-=

Qiao Yi walked over at this time, "How did you do the exam?"

Cao Song interrupted: "Don't talk, you must understand mathematics carefully."

Qiao Yi: "…"

However, the assistant teacher soon came out and posted a ranking on the bulletin board on the wall of the discussion class. In this way, everyone can see the rankings of others. Who is stronger can immediately know who is better.

Ouyang Zhe was not surprised that Qiao Yi saw Li Xuan's ranking, but it was just average and chuckled softly.

"It's okay," he said.

...

...

The one who did well in the exam was very proud, but the one who did poorly was deeply hit.

If you do too many simple questions, students can easily overestimate their math level. If you don’t do difficult questions, you don’t know your shortcomings. You are a stolen person in school, but when you come here, you may be nothing. Only by comparing with the top students in the country can you know the gap.

After knowing the ranking, many students fell into autism. It was difficult to do one of these problems.

After a while, a tall and thin professor walked into the discussion class. He was responsible for the test papers. Of course, he was not the one who corrected the test papers alone, but several assistants helped.

The difficulty of correcting this kind of test paper is greater than that of ordinary test papers. Some students will give new solutions, which are wild and imaginative. The marker must be able to understand the students' solutions. Some students will take tricks and push them from the conclusions and conditions to the middle, and write an obvious way to the middle... for various reasons, increasing the difficulty of correcting the paper.

Professor Tian Ye walked up to the podium and said, "Who is Qi Tianyun? Please stand up, I got the full mark this time."

Qi Tianyun stood up silently.

Li Xuan turned around and saw Qi Tianyun.

His eyes were empty, his hair was long and his hair was raised, and he had no time to sort it out. He looked like a taciturn person.

Zhou Lele sighed: "People who don't like to talk are very good at math, and they are sincere and don't deceive me."

Li Xuan was stunned for a moment and couldn't help laughing.

Every student has his own weaknesses and strengths. Some students have a better sense of mathematics, while others have strong spatial thinking. This is especially true for Ouyang Zhe, whose weaknesses and strengths are particularly obvious.

But Qi Tianyun is different. He is not particularly strong in one aspect. He is a truly balanced student. He is not very talented in mathematics and is a hard-working student who is particularly hardworking.

This morning, Qi Tianyun was the first to arrive in the classroom. Li Xuan said he had seen him.

Diligence is the greatest genius. Li Xuan has always thought this way, so he admires those who work hard.

Professor Tian Ye said: "Who is Li Xuan?"

Li Xuan was stunned for a moment. His score was not high, and the professor had no reason to call him. He raised his hand: "I."

Professor Tian Ye smiled: "This time, there are fewer students who have done geometry problems, and the students' solutions are very complicated, but your solution is very special and simpler than the answers we gave. Come up and write down your solution."

Li Xuan suddenly realized and went on stage to write his solution on the blackboard as he said.

Qiao Yi's eyes lit up, "Can you still understand this way? It's really a god."

Everyone watched Li Xuan finish writing quietly, giving him face and applauded.

"Did you understand?" Professor Tianye exclaimed, "This question can be solved in this way. Constructing a circle in this way is really a unique solution, which makes people sigh at the beauty of geometry."

The students below also started to communicate with each other. This did not violate any discipline. The discussion class was about communicating and discussing with students.

...

...

It was another exam at night, and the questions for the exam the next day were relatively simple, which made many students who were about to collapse feel better.

In the next few days, I went to class and took exams during the day. The difficulty of the exam questions kept changing, and it was difficult for students to determine which question was simple in a short period of time. Sometimes they were stuck on difficult questions, causing the grades to fluctuate.

Ouyang Zhe is relatively simple, so he chooses the number theory algebra he is good at to do. He doesn't force the questions that he can't do.

There are many examples of such things: bad attitude, poor tests before, and worsen afterwards.

Li Xuan is just the opposite, the more he takes the exam, the better.

...

...

With the algebra class and the combination class, Li Xuan made more obvious progress and began to explode. His ranking began to rise rapidly. On the fifth day, he got all four major questions.

The rankings are also changing. Some people are even good at writing difficult questions, but they are brushed down by simple questions. There are also such freaks.

On the sixth day, the student came to the bulletin board and saw that Li Xuan was seventh, and Qi Yuntian was still the first.

Li Xuan admired Qi Yuntian very much. He would do whatever kind of questions he had and always maintained his first position. Every morning, he always went to the classroom to study for himself.

Then a talented man from Zhejiang Province emerged from a high school, surpassing Ouyang Zhe, who temporarily ranked third.

Li Xuan didn't think much about it, adjusted his condition, and kept learning and making progress every day.

He also discovered something.

The last time Snow White performed video was discovered by fans of the tease, and they began to comment on the video. Many netizens who like "Snow White" on the Internet found his tease number based on these comments, and began to find out that he was a man.

Then his fans began a new round of crazy growth.

There is also appreciation value as it rises rapidly.

The system prompted him: [Get another 10,000 appreciation value.]

Li Xuan added most of his appreciation values ​​to improving his thinking logic.

...

...

Zhou Lele doesn’t know the difficult questions, nor does it mean that you can do it in a simple question. It’s best to do one of the exams. I feel that the balance of IQ is insufficient, so I just do it casually and pay attention to this ranking.

Then he found that Li Xuan's progress was a bit terrifying. By the last three days, Li Xuan's ranking had risen to the top five. This rapid increase in ranking has attracted many people to notice.

On the eighth day, Zhou Lele stared at the bulletin board in a daze. Li Xuan was fourth, and it was a little different from Ouyang Zhe. He found that he was beginning to look forward to it, wondering who would laugh to the end of Li Xuan and Ouyang Zhe.

Cao Song's face also changed, "If you continue to do this trend, Li Xuan will be the top three in the end!"

Ouyang Zhe looked at him silently, with nothing to say.

Li Xuan began to show his sharpness.

As long as the knowledge he has learned and the skills he has learned, he can always learn from it and grasp the most essential things. Because he has not tried most of the difficult questions, the answers he gives are very unique and very innovative.

Since the training has reached now, Li Xuan often finishes all four major questions in every exam, and he keeps full marks afterwards. Even a versatile talent like Qi Tianyun has failed many times, but Li Xuan has never had any accidents.

Especially Li Xuan often has magical solutions on geometry problems, and he is often mentioned by Professor Tian Ye in the discussion class.

Qiao Yi also noticed Li Xuan's progress, and now he was only in shock to describe it: "What's going on with this guy?"

On the last day, the question type changed again. The college questions were tested, and the probability of the first question was started.

This kind of question is just right for Li Xuan.

Few students will practice the question types in college deliberately, and without practice, you cannot rely on experience. In this way, the last day of the exam will pay more attention to students' talent and understanding of mathematics.

In the exam room, Li Xuan was like an eagle looking down at the earth in the sky, calm, calm and sharp.

He calmly picked up the test paper to read.

What caught my eye was the simplest question:

"Two people gamble, each time they bet 1 yuan, A has a yuan, B has b yuan, A's probability of winning is p, the probability of losing is q, and the probability of sum is r, find the probability of A's final victory."

This question is simple at a glance, but it is very complicated to think about it carefully.

But Li Xuan couldn't help but smile, picked up the pen and solved it quickly.

Then look at the next question.

When the last day the exam results came out, many people were surprised to find one thing. Qi Tianyun, who was originally the first, suffered a Waterloo and only got one of four major questions. This was the worst day he had.

Li Xuan still maintained the full score, the only full score, like a king looking down at all living beings.

When I saw the results, many people were sensational.

"Li Xuan is the first! What's going on?"

"On the last day, Qi Tianyun made a mistake. As long as he made two big questions, he would not be surpassed by Li Xuan! Not to mention Qi Tianyun, the second-hand Wang Jie also made a mistake. Ouyang Zhe made three questions, and Li Xuan broke out completely."

"It's not that Qi Yuntian is the last day when I take all the college knowledge, and the questions are difficult, so I didn't get a single one."

"Except for poor performance on the first day, I made three tricks on the second day, three tricks on the third day, three tricks on the fourth day, and then on the fifth day, Li Xuan started to score full marks."

...

The question types on the last day were too biased, and the probability, analysis and topology were tested. Perhaps the organizer wanted to see the students' ability to solve new problems after receiving new knowledge.

Because some competitions have outstanding results, they are developed too early and are improved through a lot of deliberate practice and sacrifice others. This is very utilitarian, and people's potential is exhausted and the energy is exhausted. Sometimes the results do not explain the problem.

At this time, teaching students new content. If you can still get full marks, you are really talented in mathematics. If such students go to college, they will not be like the former, and will burst into huge energy, and will only become more and more perverted in the future.

In front of the bulletin board, Zhou Lele was stunned and couldn't figure it out.

Ouyang Zhe looked quietly for a while, his eyes were stunned and his heart was filled with incredible feelings.

He turned his head and his eyes fell on Li Xuan's face.

Li Xuan's eyes were as calm as water, and there was no unexpected look on his face, as if he had expected it.
