Although the competition between the three parties is fierce, none of them smell of gunpowder, and Yun Xiangxiang will ignore it.

Turning her head to continue working on her math problems, she was still a little nervous when it was a school competition tomorrow.

It is more nervous than the college entrance examination, which is an admission probability, and the candidates are mixed.

This mathematics competition is a mathematics student who includes the entire school, no diamond and no porcelain work, and the participants are basically full scores in mathematics in the college entrance examination, and the mathematics scores are among the best.

Although she was a little nervous, it didn't affect Yun Xiangxiang's sleep quality, and she got up early to go to school.

"Think about it, you're finally back, worry about me to death." Tao Mani pounced on Yun and thought about it.

Yun Xiangxiang's Weibo also hides the address, so they naturally won't check Yun Xiangxiang's IP. It hurt them all to think that Yun Xiangxiang was still abroad, and if they didn't participate in this game, they might be sprayed out.

"Unless I can't get up, I'm not going to miss any occasion I've set for myself." Yun Xiangxiang put breakfast on the table, "It's for you." ”

"We've already eaten it, but I can still eat it." Feng Xiaolu took it and said with a smile.

Because they were worried that Yun Xiang would not be able to come back, they got up early in the morning and couldn't go hungry, but they didn't have much appetite.

Today is Friday, there is no class in the first period in the morning, and the math competition will start at 9:40, so Yun Xiang doesn't have to go to the morning class.

"You also said that No. 1 is back, and we are all waiting for you." Tao Mani stared at the clouds and thought, "Celebrate with me tomorrow?" ”

"Okay, I'll have a treat tomorrow." Cloud Think Promise.

"Yao Yao and Xiao Yuan, I will notify the group in a while, do you want to call Yang Qi?" Ma Linlin asked.

"Call it, I'll call Xiangling and Mengmeng by the way, it's crowded." When I was notified yesterday, Song Meng was clamoring and wanted to eat roast duck.

Song Meng had an obsession with the roast duck, Yun Xiangxiang agreed considering the quiet environment over there, and sent an address in the WeChat group of the dormitory: "Dinner is here, it's a little far, you have to take the subway first and then transfer to the bus." ”

"What about the suburbs, we ride bicycles, is there a KTV nearby, go to KTV after dinner?" Tao Mani asked, looking at the address.

"Spare me, I want to go back early, I have a lot to do." Yun Xiang immediately forgives, and went there in the hope that they would not continue to be hi.

Although she was disappointed, thinking that Yun Xiangxiang was really busy, Feng Xiaolu snorted: "If you don't go to Hi, then let's eat with our belly open!" ”

"Eat, eat, eat, you can eat as much as you want." This cloud thinks about it and says that there is no pressure, "You can play mahjong and billiards there...... We'll go over at noon and spend an afternoon with you. ”

Riding at noon, they were together again, and Yun thought about it was still more reassuring. Disperse early in the evening, let Qianqian drive an extra car, and send them home safely, Yun Xiangxiang can feel at ease.

happened to be the car that Lu Jin gave her, she went on the road when she watched the fashion show, and arrived in China one day earlier than her, so that Song Qian and Alley had one by one, and Song Meng and Li Xiangling followed her back for one night.

Next, Yun Xiangxiang distributed the gifts he brought back from Italy to them, including the bedroom next door.

Several people laughed for a while, Tao Manni and the others went to class, and Yun Xiang went to the examination room. The head of the department who invigilated the exam was relieved to see her, it was really painful and happy to have such a student.

When there were still five minutes before the test paper was issued, the head of the department held the sealed bag: "There are only 44 freshmen participating in this mathematics competition, and our test questions are very different from previous years, not only to test your ability to calculate and use, but also to test your understanding of academic and historical problems in mathematics. ”

As soon as these words came out, there was a wail.

The academic problems are fine, they are basically related to formulas, but the mathematical history problems are over.

Yun thinks about it and doesn't know the bottom in his heart, don't look at it as a mathematical history problem, find a history student, they may not be able to pk.

When the test paper is sent, there are three math history questions in the multiple-choice questions.

The first way: Who is known as the ancestor of modern mathematics in China?

The four answers are all Chinese mathematicians, I really don't know if I think about this question, I can only rely on the age of the four people, since it is the ancestor, it must be the one with the highest achievement, the most contribution, and the oldest!

The second way: Who is the founder of Huaguo mathematical mechanization research?

Yun wanted to know this question, Song Mian mentioned it when he told her about the field of mathematical mechanization.

It just so happens that the correct one of the four options in this question is also in the answer to the first math history question.

This improved the correctness of the previous question by 25 percent.

The third way: Who founded the first mathematical journal in China, the Journal of Computing.

Four answers, one and one repeats the first question, Yun Xiangxiang understands, this is not only a historical question, but also a probability question.

Luckily, she knew the correct answer to the second question, so that although she couldn't deduce the correct answer, she was undoubtedly closer to the correct one, and it wasn't difficult to guess if she knew a little bit about the other answerers.

After completing the ten multiple-choice questions, it is a fill-in-the-blank question, and the fill-in-the-blank question also has two mathematical history questions.

The first way: who is the founder of the Chinese school of calculus geometry.

This Song Mian mentioned when she was teaching her the geometry school of calculus, Yun Xiangxiang answered quickly, and after writing, she looked back at the ten answers to the previous three multiple-choice questions.

This one is undoubtedly among the ten completely unrepeatable answers.

Yun Xiangxiang quickly searched for the second historical fill-in-the-blank question: Who is a self-taught mathematician in Huaguo, a legendary formula.

This question has been mentioned by the math teacher in one of the few classrooms in Yunxiang, and it can be regarded as a scoring question.

This answer is undoubtedly also in the multiple-choice answers, and the guess in my mind is confirmed, and some of the questions are indeed extracurricular knowledge.

But as long as you listen to the content of the class and remember it, you don't need to accumulate it outside of class, and you can use the elimination method to get the multiple-choice questions right.

There is also a true/false question involving the above ten answers, the true/false question is correct, and one more option is excluded.

It depends on whether the students in class memorize these characters carefully, but Yun Xiangxiang guesses that most of them will not remember these.

Many mathematicians are comfortable with the formula, but they never know who the formula comes from.

Yun thought about it and continued to do the questions, most of them were calculation and application questions, and her efforts these days were not in vain, and she had already done several questions, using the knowledge points they had not yet learned.

When he did the first question, Yun Xiangxiang really couldn't help laughing.

This is a very classic math problem that tests IQ at the highest international universities.

When it was first announced, many people were stunned.
