Chapter 49 Heartache
“The largest integer k such that 10 to the power of k divides 199 factorial.”
Wu Tong read the question carefully and got an idea. It was not a very complicated question and the meaning was very clear.
Wu Tong took the pen from Teacher Li and continued to write down the solution process on the draft paper. According to Theorem 3, the exponent of 5 contained in the decomposition of 199! is ···, and the positive integer K contained in 2 is 47, ···
"So, the largest positive integer we are looking for is K, which is equal to 47, Teacher Li!" Wu Tong looked at Li Yishen and gave the answer without hesitation.
After Wu Tong announced the answer, Li Yishen's eyes instantly became brighter than those of Mr. Zhou from the Admissions Office. His excitement almost broke through the wall and finally turned into a deep sigh.
"It's a pity that I met you only now. If you are willing, I invite you to go to Kyoto University to study in advance. The Department of Mathematics at Kyoto University welcomes you!"
"Teacher Zhou, this is a math graduate exam question. Wu Tong's answer was clear and concise, and it was correct!"
"Wu Tong has already mastered college mathematics thoroughly! Her level of knowledge is almost equivalent to that of a graduate student at Peking University. For a child like this to stay in a small county with poor educational resources and be trapped in a county high school that mechanically reviews questions is a real waste of talent!"
I feel so sorry for him!
With scarce resources and limited teaching materials, this child has been able to learn to this level through self-study. His talent and learning ability are simply astonishing!
If, this child grew up in an environment with abundant educational resources, if they could meet this child earlier, then how dazzling would this child's growth be!
Fortunately, the child was only sixteen years old, and they were lucky enough to meet this child! As long as the child grew up, he would not be surprised that the child could surpass his achievements and become the pride of Beijing University.
Professor Li pointed at the student representatives who were watching and said, "Look at the expressions of these losers and you will know Wu Tong's level!"
“Hehe…” Several seniors smiled awkwardly. Teacher, don’t look at them, they are really just ordinary shrimps struggling to survive!
Compared with the evil bosses who are fighting for the school's million-dollar bonus, they are not worthy!
"Thank you for your compliment, Teacher Li. Mathematics is a profound subject. I am probably still circumventing the threshold and haven't gotten started. I haven't been exposed to all the university textbooks, and there are some things I may not have learned or mastered. I still need to continue learning!" Wu Tong said modestly, as she studied a different field, it was difficult to compare herself with her seniors.
“The way my seniors deal with people and their thoughtfulness and consideration are what I want to learn!” I had just enjoyed their care, and I couldn’t let my seniors lose face.
As soon as these words were spoken, several student representatives immediately gave grateful looks to their future junior schoolmates, saying what a good person she is.
"Go back and pay attention to advanced mathematics." Li Yisheng gave a warning look to those who were happy. They were all waiting for him.
Signing the contract is the most important thing. Teachers Zhou and Li did not waste time. In the presence of her parents and coach Zhang, Wu Tong formally signed her name on the final agreement prepared by the Peking University Admissions Office and made the plan to go to Peking University to study early after the beginning of the year.
"Classmate Jin Xin, do you want to come to Peking University to study with me? Your grades are not bad, why don't you go to Peking University with our classmate Wu Tong?" After calming down, the atmosphere during the signing process was more relaxed. Mr. Zhou from the Admissions Office chatted with the Jin and Wu family about family matters.
Knowing that Jin Xin had been receiving tutoring from Wu Tong in the past few months and that his grades had improved by leaps and bounds and were now above the 660 line, especially in math and comprehensive science, where he had firmly stood above the 140+ and 280+ lines, Wu Tong couldn't help but recruit him with a smile.
This score is really not far from the admission score line of Peking University. Especially in mathematics and comprehensive science, he is very good. With the strong support and tutoring from Wu Tong, his college entrance examination score is definitely an unexpected dark horse, which makes people happy. It is definitely worth it to package it with Wu Tong.
"Hehe... Peking University was the goal agreed upon by Tongtong and I. Now, I have decided on my direction. I want to apply to a military academy!" Jin Xin scratched his head embarrassedly. If he had just entered the third year of high school, he would have agreed wholeheartedly upon hearing this news. But now, he would not want to take advantage of Tongtong.
"You're going to apply to a military academy, what great ambition. The teacher wishes you a bright future!" Teacher Zhou applauded and praised them. This family really knows how to raise children. Each of the two children has their own clear goals and works tirelessly for them. It's really enviable!
After the signing was completed, Teacher Zhou was particularly thoughtful and arranged a midnight snack and invited other members of the Central Plains Provincial Team to come over. Following his professional habit of raking straw to catch rabbits, he promoted Beijing University to the remaining players of the Central Plains Provincial Team.
The Zhongyuan Provincial Team did well this year. In addition to Wu Tong, who won the first place in the CMO with a perfect score, there are two other gold medals. Among them, the girl named Feng Yueyue scored 87 points, which exceeded the national team score line this year and can enter the national training team. In other words, two people from Zhongyuan Province will be able to enter the national training team this year, which 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 Zhongyuan Province and 30th in CMO, finalized an agreement for admission to the Department of Mathematics of Peking University, as well as another national first-class gold medal winner, to Peking University's Strong Foundation Program.
"The teacher will send you some textbooks later. You can read them slowly. If you don't understand something, you can ask me anytime. When you come to Peking University, we can discuss it together." Before Wu Tong returned to his room, Professor Li gave Wu Tong the analytic number theory he brought with him and told him. He actually prefers functional analysis, and he studies number theory to learn by analogy. He happened to have this textbook in hand, so he gave it to his child first.
He felt heartbroken just thinking about how such a talented student couldn't continue his studies because he couldn't borrow textbooks!
"Thank you, Teacher Li. See you at Peking University after the New Year. I'll go and wish you a happy new year!" The county town really couldn't provide her with more learning resources, and coupled with the training team training after the New Year, Wu Tong planned to go to the capital at the beginning of the year.
This year's IMO national training team is training in Jiangcheng. According to what Teacher Li told them in advance, they will be directly recruited by Peking University and will train at Peking University next year. She can go there in advance, and the school will arrange her study and life.
At 9:00 the next day, the awards ceremony for the 24th Chinese Mathematical Olympiad was held. Hosted by the Chinese Mathematical Society, the awards ceremony began.
This year is an odd-numbered year, and the test setters have increased the difficulty. This year, the score for the first prize is unprecedentedly low. The first prize score is 66 points, and the national training team is limited to 75 points.
This year, there are 42 national first prize winners and 30 national training team members. The second prize score is 50 points, and the third prize is not counted. Those who can enter the national competition generally use this as a consolation prize.
When the news reached Zhongyuan Province, the people in Zhongyuan who were following the news were delighted.
