But at this time, a blonde old man was sitting at the desk, checking the Olympiad exam papers, and this old man was Professor Xu Xiansen Xu who had just been spoken by Teacher Yu. Although Professor Xu is already a university professor and an authority on mathematics in China, he is still as serious and rigorous as he treats mathematics.

In fact, this Olympiad exam paper should not have been issued by him, although the Olympiad competition has always been very important, but it is only a domestic Olympiad for junior high school students, and it will not ask the top authority in the country to come up with questions. However, because in recent years, there has been no mathematical genius who can take the lead in China, all of them are supported by those old professors, and there is no new generation to take over, and he is a little sick and rushed to the doctor.

However, in the end, in fact, Professor Xu was not asked to come up with the questions, because Professor Xu was too busy to spare time, and the final test questions were given by Professor Xu's student Professor Chen, although his qualifications were not as good as Professor Xu, but his major was not bad, but the news was released and he did not have time to take it back.

Su He didn't know before, but Su He participated in a lot of competitions later, and also learned that this world is still slightly different from Su He's previous life, although there are also Olympiads, but the topics of the Olympiad are also changed on the basis of mathematical problems, which are more flexible and changeable than math problems, and are a bit similar to the previous life, but they are not as perverted as in the previous life, and there is a situation where even the mathematics professor can't do the problems, and these questions are all from the mathematics teacher, whether it is a regional junior high school Olympiad, It is also a domestic high school Olympiad and an international Olympiad.

Professor Xu didn't care about it after handing over the questions to the students before, and was busy with his own project, no, now that the project has just ended, Professor Xu remembered the Olympiad questions, so he asked the students to take a test paper to check it.

The test paper is not divided into grades, and is answered by junior high school students, which is a great loss for students in the first and second years of junior high school, some knowledge points have not yet been learned, and the difficulty will be greater, but it is not simple for junior high school students, and it is naturally very simple for a mathematics professor.

As a professor of mathematics, Professor Xu didn't find a mistake like Su He's calculations a few times, and when he was almost halfway through the calculation, he felt that something was wrong, right. In order not to wronged the student, he read it again, and finally put down the pen, and Professor Chen, who gave the question, called and beckoned him over.

"You can calculate this question" As soon as Professor Xu came up, Professor Xu didn't say much, and directly asked Professor Chen to answer the last big question.

"Ah, good," Professor Chen was stunned for a moment, but quickly reacted well. Professor Chen was a doctoral student under Professor Xu's name when he was young, and the difference between the two was a few years old, and Professor Xu usually did not say anything serious or ordered to Professor Chen, and the two of them did not get along like teachers and students, but like friends, and there was no tone like today, so Professor Chen was stunned for a moment.

Professor Xu stood up and watched him solve the problem behind Professor Chen. Professor Chen also lived up to his name as a mathematics professor, and suddenly felt that something was wrong, and after careful scrutiny, Professor Chen exclaimed: "No, this number is not right, I clearly wrote 8 when I came out of the question, how could it become 3?"

Professor Xu was also stunned: "This difference is too far, who printed and typeset the volume, and why did there be such a big mistake?"

"I directly asked my students to typeset, this is too unsatisfying, I'll ask how the exam is going first, and then I'll bring that stinky boy over" After speaking, Professor Chen hurriedly went to call someone to find someone. However, after a while, he walked in dejectedly.

"I called and asked, the exam is over, and it's too late to arrange to change the question, alas, I called that little rabbit cub over, I always want to see what the specific situation is, who made the mistake"

Professor Chen is a little decadent at this time, he is also very sad about this situation in his hands, if he finds it in the middle of the competition, he can also change it, and now that the test papers are all received, he can't change it if he wants to. And he knows that this exam is not just a small competition, this time it is national, and the last question is prepared for the country to test talents in advance and recruit talents, covering a lot of content, and now this is ruined by a small number of his figures.

"Hey, it's too late to say anything, call someone over first, let's see how to remedy it first" Professor Xu was also worried, this is a major accident, how to deal with it.

Professor Chen lowered his head and kept silent, he couldn't think of any good way to solve it at this time, things had already happened, right under his nose, and at the moment his heart was in a mess, and he couldn't concentrate at all.

"At present, we can only look at the steps of the candidates, if the steps are all correct, it will be counted as a full score," Professor Xu muttered, "but I am afraid that there is a situation that there are some candidates who have the right steps at the beginning, but the final result cannot be calculated, so it is not written on the test paper."

Professor Chen, who was still stunned after listening to the front, was hit by the latter paragraph, in fact, it is indeed very unfair to some candidates in this way, and some of these candidates may be better.

"Hey" Professor Chen sighed, he is a very responsible person, and he is very uncomfortable with the delay of the candidates because of his own mistakes.

At this time, Zhang Jing walked in, Zhang Jing is a doctoral student under Professor Chen, and this time she is responsible for the layout of the test paper, just when Professor Chen called her, told her the situation, just looked at the test paper, but she can be sure that she did not make a mistake in the numbers, because she is a very careful person, after editing, she also specially corrected several times, absolutely will not make mistakes, for this reason, she also turned out the document she sent to the teacher in charge of printing, it turns out that she did not make a mistake.

Then she went to the printing room again to understand the situation, and after carefully looking at the monitoring, she learned that the printer got up to pour water, and the cup was pressed to the keyboard, which should have been pressed at that time, although this was a small mistake, but it caused a serious consequence.

Zhang Jing came late at this time because she went to understand the situation. Although the main reason for this mistake was not her, she also made a serious mistake and arranged it out without checking it after receiving the test paper. This made her, who had always been careful, unable to accept that she had made such a low-level mistake.

After Zhang Jing explained the details of the matter, he lowered his head, "Mentor, I'm sorry, I was careless, and I didn't check it again after printing."
