Before returning to the college entrance examination, I became popular in the science circle

Chapter 49
"The largest integer k such that 10 raised to the k power divides the factorial of 199."

Wu Tong read the question carefully, and came up with an idea. It's not a question that is too cornered, and the meaning of the question is very clear.

Wu Tong took Teacher Li's pen and continued to write down the problem-solving process on the draft paper. Theorem 3, 199!The exponent of the power of 5 contained in the decomposition formula is..., and the positive integer K containing 2 is equal to 47,...

"So, the largest positive integer you are looking for is K equal to 47, Mr. Li!" Wu Tong looked at Li Yisheng, and reported the answer without hesitation.

After Wu Tong reported the answer, Li Yisheng's eyes were instantly brighter than those of Mr. Zhou from the Admissions Office. His excitement nearly burst through the wall, and finally turned into a deep sigh.

"It's a pity, teacher, I just met you now. If you want, the teacher invites you to go directly to Peking University to study in advance. The Department of Mathematics of Peking University welcomes you!"

"Ms. Zhou, this is an exam question for a graduate student majoring in mathematics. Wu Tong's answer process is concise and clear, and it is correct!"

"University mathematics, Wu Tong has already mastered it thoroughly! Her level of knowledge is almost equivalent to that of a graduate student of Beijing University. It is true that such a child stays in a small county with poor educational resources and is trapped in a high school in a county where mechanically reviewing questions. What a waste of talent!"

I feel sorry for him!
Resources are poor, teaching materials are limited, and self-study can learn this level. This child's talent and learning ability are simply amazing!
If this child grew up in an environment with abundant educational resources, and if they could meet this child earlier, how dazzling this child's growth would be!
Fortunately, this child is only 16 years old, and they are lucky enough to meet this child!As long as this child grows up, he will not be surprised that this child can surpass his achievements and become the light of Beijing University.

Professor Li pointed to the several accompanying student representatives who were watching, "You can see Wu Tong's level just by looking at the expressions of these unlucky guys!"

"Hehe..." Several seniors smiled. Teacher, don't look at them. They are really just ordinary little shrimps struggling to survive!

Comparing them with the monstrous bosses who are fighting for the school's million dollar bonus, they are not worthy!

"Mr. Li is so complimentary. Mathematics is a broad and profound subject. I should still be struggling with the basics and haven't gotten started. I don't have enough exposure to college textbooks. There are still some things I haven't learned or mastered. I still need to continue learning!" Wu Tong was embarrassed and self-effacing. Tao said, her studies are in different directions, so it is difficult to compare her with several seniors.

"Seniors and sisters behave in the world, they are thoughtful and meticulous, I want to learn!" Just enjoying their care, I can't let the seniors and sisters get off the stage.

As soon as these words came out, several student representatives immediately sent a grateful look to the future primary school girl, good person.

"Go back to high math and give me a lot of attention." Li Yisheng gave warning eyes, glanced at those lucky guys, and waited for him
Signing the contract was the most important thing. Teachers Zhou and Li were not wasting time. Witnessed by her parents and Coach Zhang, Wu Tong officially signed her name on the final agreement drawn up by the Admissions Office of Peking University, and decided to attend Peking University in advance after the beginning of the new year. plan.

"Student Jin Xin, do you want to come to Peking University together? Your grades are also good. How about going to Peking University with our classmate Wu Tong?" After settling down, the atmosphere during the signing process was relatively relaxed. Teacher Zhou from the admissions office and the Jin Wu family People chat about everyday things.

Knowing that Jin Xin has been supplemented by Wu Tong for the past few months, her grades have improved by leaps and bounds, and now she has taken the 660 line, especially in mathematics and comprehensive science, and has firmly stood at the 140+ and 280+ lines, so she couldn't help smiling.

This score is really not far from the admission score line of Beijing University, especially mathematics and science can be said to be very good, and there is such a strong support as Wu Tong and tutoring. The college entrance examination score is definitely a surprise dark horse, which makes people happy. It's definitely not a loss for Wu Tong to pack together.

"Hehe...Beijing University was the goal that Tongtong and I agreed on before. Now, I have determined my direction and want to enter the military academy!" Jin Xin scratched his head in embarrassment. Hearing this news when he was just in his third year of high school, He had to agree with both hands and feet. Now, it would be hard for him to take advantage of Tongtong.

"Entry into the military academy, good ambition, the teacher wishes you a bright future!" Teacher Zhou applauded and praised, this family really knows how to raise children, each of these two children has their own clear goals, and they work tirelessly for them, it is really amazing It makes people look hot!

After the signing was completed, Mr. Zhou was very thoughtful, arranged a supper, and invited all the other members of the Central Plains Provincial Team to come over. With the professional habit of hugging grass and hunting rabbits, he promoted the remaining players of the Central Plains Provincial Team to go to Beijing University.

The Central Plains Provincial Team has achieved good results this year. In addition to Wu Tong, the unprecedented CMO with the highest perfect score, there are two other national first-class gold medals.Among them, the girl named Feng Yueyue surpassed this year's national team score line with 87 points and can enter the national training team.That is to say, two people from Central Plains Province will be able to enter the national training team this year. This is a very good result. Coach Zhang Ping and Teacher Xiao Zhang are very happy.

Teacher Zhou was also very happy. He and Feng Yueyue, who ranked second in Central Plains Province and ranked 30th in CMO, finalized an agreement to be admitted to the Department of Mathematics of Peking University, and another national first-class gold medal winner entered Peking University’s strong foundation plan.

"Teacher will send you some teaching materials first. You can read them slowly. If there is anything you don't know, you can ask me at any time. When we come to Beijing University, we will discuss it together." Before Wu Tong returned to the room, Professor Li asked him He gave the analytic number theory he carried with him to Wu Tong and warned him.In fact, he is more interested in functional analysis. He studies number theory for the sake of analogy. He happened to have this textbook in his hand and gave it to his children first.

It made him feel sad to think that such a talented student could not continue studying because he could not borrow the textbooks!
"Thank you, Mr. Li. I'll see you in Beijing next year. I'll give you New Year's greetings!" The county really couldn't provide her with more learning resources. Coupled with the training of the training team next year, Wu Tong made a plan to go to the capital in the beginning of the new year. .

This year's IMO national training team is training in Jiangcheng. According to Teacher Li's advance notice, they will be directly taken over by Beijing University and will train at Beijing University next year.She can go there in advance and the school will arrange her study life.

At nine o'clock the next day, the No. 20 Fourth Chinese Mathematical Olympiad Award Ceremony was held.With the Chinese Mathematical Society hosting the ceremony, awards began to be awarded grandly.

As this year is an odd year, some proposition groups have increased the difficulty. This year’s score for the national first prize is also an unprecedented low.The national first-class score cutoff is 66 points, and the national training team is blocked with 75 points.

This year, a total of 42 national first prizes and 50 national training players were produced.The score line for the second prize is [-] points, and the third prize is not counted. Those who can enter the national competition are generally used as consolation prizes.

The news spread back to the Central Plains Province, and the teachers in the Central Plains who paid attention to the news were full of joy.
