But at this time, a hale and hearty old man with blond hair was sitting at the desk, checking the Mathematical Olympiad test papers. This old man was Professor Xu Xiansen, whom the teacher just mentioned. Professor Xu was budgeting one question after another, although
He is already a university professor and an authority in mathematics in China, but he still treats mathematics with the same seriousness and rigor.
In fact, he should not have written the Mathematical Olympiad test papers this time. Although the Mathematical Olympiad competition has always been taken seriously, it is just a domestic Olympiad for junior high school students, and the top domestic authorities will not be asked to set the questions. However, due to recent years,
, there has never been a mathematical genius who can take the lead in the country. It is all the old professors who are supporting it. There is no new generation to take over. I am a little sick and have to seek medical treatment. This time, Professor Xu is asked to take action, and the first thing is to start with the Olympiad questions.
.
However, in the end, in fact, Professor Xu was not asked to write the questions because Professor Xu was too busy and could not spare the time. The final test questions were asked by Professor Chen, a student of Professor Xu. Although he was not as qualified as Professor Xu,
The professionalism is not bad, but the news was released and there was no time to take it back.
Su He didn't know this before, but later Su He participated in many competitions and learned that this world is still slightly different from Su He's previous life. Although there is also an Olympiad, the questions in the Olympiad are based on mathematics questions.
The math questions are more flexible and changeable, a bit similar to the previous life, but not as abnormal as the previous life. There are questions that even the math professor can't do, and these questions are all given by the math teacher, whether it is a regional junior high school Olympiad
, as well as domestic high school Olympiads, college competitions and international Olympiads.
Before, Professor Xu handed over the questions to the students and never took care of them again. He was busy with his own project. No, now that the project had just ended, Professor Xu remembered the Olympiad questions and asked the students to take a copy.
The test papers are here for verification.
The test papers are not divided into grades and are answered by junior high school students. This is very disadvantageous for students in the first and second grades of junior high school. Some knowledge points have not been learned yet and the difficulty will be higher. But it is not easy for junior high school students.
It is naturally very simple for a mathematics professor. Professor Xu nodded while doing general calculations. The questions he came up with were very novel, but in the end he stopped at the last question and got stuck.
As a professor of mathematics, Professor Xu was not like Su He who only discovered the error after calculating it several times. After almost half of the calculation, he felt that something was wrong. In order not to wrong the students, he read it again, finally put down his pen and gave
Professor Chen, who came up with the question, called and invited him to come over.
"Please do the math on this question." When the question came up, Professor Xu didn't say much and directly asked Professor Chen to answer the last big question.
"Ah, okay." Professor Chen was taken aback, but he quickly responded. Professor Chen was a doctoral student under Professor Xu when he was young. There was only a few years difference between the two of them, and Professor Xu usually wouldn't
No matter what harsh words or orders were given to Professor Chen, the two of them did not interact like teachers and students, but rather like friends, not even in the tone they used today, so Professor Chen was stunned for a moment.
Professor Xu stood up and watched him solve this problem from behind Professor Chen. Professor Chen was worthy of his name as a mathematics professor. He immediately felt that something was wrong. After careful consideration, Professor Chen was shocked and said: "It's wrong. This number is wrong."
That’s not right, when I wrote the question, I clearly wrote 8, how could it become 3?”
Professor Xu was also stunned when he said: "This difference is too far. Who printed and typeset the paper? How could there be such a big mistake?"
"I directly asked the students below me to do the typesetting. This is too unsatisfactory. I will ask how the exam is going first, and then bring that brat over." After saying this, Professor Chen hurried to type.
I called someone. But after a while, he walked in dejectedly.
"I called and asked. The exam is over. It's too late to change the questions. Alas, I called that little bastard over to find out what exactly happened and who made the mistake."
Professor Chen was a little decadent at this time, and he was very unhappy when this happened to him. If he found out during the competition, he could still make changes. Now that the test papers have been collected, he can't make changes even if he wants to. And he knows this
This exam is not just a small competition. This time it is national in nature. The last question is prepared for the country to test and recruit talents in advance. It covers a lot of content. Now it is ruined by his small number.
.
"Hey, it's too late to say anything now. Let's call people over first and let's see how to remedy the situation first." Professor Xu was also worried. This was a major accident. How was he going to handle the matter?
Professor Chen lowered his head and remained silent. At this time, he could not think of any good way to solve the problem. Everything had already happened, right under his nose. Moreover, his mind was in such a mess that he could not concentrate at all.
"Currently, we can only look at the candidates' steps to do the questions. If the steps are all correct, full marks will be calculated," Professor Xu said thoughtfully, "But I am afraid that there will be a situation where some candidates have the steps right at the beginning, but in the end
If the result cannot be calculated, it is not written on the test paper.”
Professor Chen, whose eyes lit up after hearing the previous words, was shocked by the following words. In fact, it is very unfair to some candidates, and some of these candidates may be better.
"Hey" Professor Chen sighed. He is a very responsible person. He is very uncomfortable with the delay caused by his own mistakes this time.
At this moment, Zhang Jing walked in. Zhang Jing was a doctoral student under Professor Chen, and she was responsible for formatting the test papers this time. When Professor Chen called her just now, he told her the situation.
She looked at the test paper, but she was sure that she had not typed the numbers wrong, because she was a very careful person. After editing, she checked it several times to make sure she would never make a mistake. For this reason, she also dug out the text she sent
I gave the document to the teacher in charge of printing, and it turned out that she did not make any mistakes.
Then she went to the printing room to understand the situation. After carefully watching the surveillance, she realized that when the printer got up to pour water, the cup touched the keyboard. It should have been pressed at that time. Although this was a small mistake, it caused serious damage.
had a serious consequence.
Zhang Jing came here late because she went to understand the situation. Although the main reason for this mistake was not hers, she also made a serious mistake. After receiving the test paper, she arranged it directly without checking it. This made Zhang Jing
She was so careful that she couldn't accept that she had made such a stupid mistake.
After Zhang Jing explained the details of the matter, she lowered her head and said, "Instructor, I'm sorry, I was careless. I didn't check it again after printing it." (To be continued)
