"Here's the competition material, you can take a look."

Tang Xinyu handed Xiao Yuan a piece of material, and after Xiao Yuan took it, he quickly scanned it.

The 15th National Mathematical Contest in Modeling for College and Middle School StudentsOrganizers: Jiangzhou Mathematics and Computing SocietyParticipants: Nationwide high school, junior college, undergraduate students Participation regulations: ...... Regardless of age, education, or grouping......

After Xiao Yuan finished reading it, he stared at Tang Tang Xinyu with strange eyes and asked, "Teacher Tang, why did you think of letting me participate in this kind of competition?" ”

"Hehe, I think you can try it, your programming ability is very strong, and the math should not be bad, so I want to recommend you to try it." Tang Xinyu explained.

"Mr. Tang, this is a mathematical modeling competition, although the modeling results should be achieved by computer programming, but the most important thing is mathematics, do you think that I am a high school student, I have not studied the relevant subjects of the university, and I have not carried out special training, to participate in this kind of competition, will I get good results?" Xiao Yuan asked, in his previous life, when he was in college, in order to improve his computer algorithm design level, he went to the mathematics department to listen to a piece of numerical analysis and modeling theory, but for other reasons, he quickly gave up, and now this is the knowledge used in this competition, so he is really not sure.

"Moreover, the rules of this competition are very problematic, why there is no distinction between academic qualifications and age, so it is unfair to let high school students and undergraduates compete." Xiao Yuan questioned again, this was the rule he didn't understand the most.

"At the beginning, this competition was grouped according to the level of education, but later, for some reason, the group was canceled, according to my sister, the topics of this competition are not much in the knowledge of the university, and all the questions focus on the flexibility and rigor of the participants' thinking, so I want to recommend you to try it." Tang Xinyu explained.

"How does your sister know so clearly?" Xiao Yuan said curiously.

"Because my sister participated in the competition when she was in high school, and she won the second prize at that time." Tang Xinyu said.

"So your sister is quite powerful." Xiao Yuan smiled with relief.

"That's natural, my sister has been very smart since she was a child, she skipped one level in junior high school, and she also skipped one level in high school, and she finished six years of school in four years." Tang Xinyu introduced with some pride.

Listening to Tang Xinyu's words, Xiao Yuan secretly admired in his heart, at least, Tang Sa's amazing performance in school, he sighed to himself.

"Xiao Yuan, don't ask so much nonsense, do you want to participate or not, oh, I forgot to tell you, this competition is stared at by many famous universities, if you win the award, they will be crazy to rob you, and then you don't have to worry about the college entrance examination." Tang Xinyu said.

"Oh, can you get a prize?" Xiao Yuan's eyes lit up and asked.

"Let's just say that, but you still have to take the college entrance examination, even if your grades are a little worse, you will be admitted to some schools exceptionally, and this kind of thing has happened many times before."

"Since there are such benefits, well, I participated." Xiao Yuan's liberal arts grades are very poor, and he is likely to drag him back during the college entrance examination, but since he won the award and can be recruited by some universities, he is very excited, so he readily agreed.

"Well, since you agreed, I'll fill out a form for you, and I'll go back to Jiangzhou this weekend and buy you a few review materials, just take the time to read them."

"Okay, thank you, Mr. Tang."

After finalizing this matter, Tang Xinyu had nothing else to do, Xiao Yuan said goodbye and left, and when he walked out of the audio-visual education building, he happened to see Yu Zhengfeng wearing a hat and a large sunglasses on his face, following behind a fat woman and walking outside the school, he couldn't help laughing, and he was very satisfied with the result he had made.

…………

When he got home from school at noon, Xiao Yuan came to the shop again after eating.

"Is there something wrong?" Xiao Changtian asked.

"I want to go to Jiangzhou on the weekend." Xiao Yuan said that the reason why he wanted to go to Jiangzhou was for two reasons, one was that he was ready to accept the challenge of the guy named Ghwolf who wrote the war book in the virus, since he was ready to fight, then he had to make some preparations, in Nanzhou, although the school computer room could be used by himself, but the computer in the school computer room was only connected to a local area network, and did not connect to the Internet, and many things he had to prepare were inseparable from the Internet; At present, although there are a small number of Internet cafes in Nanzhou, but after all, it is a public place, and the challenge of network hackers there will make him feel very unaccustomed, so he excludes these two points, and goes to Jiangzhou's mother's house and uses the computer that his mother bought for him, which has become his best and only choice.

Xiao Yuan decided to go to his mother's house in Jiangzhou, and there was another reason, the anti-tracking software spyadre that he exchanged for a circular logic lock last time was still in his mother's computer.

"Well, you can go if you want."

The so-called knowing son Mo Ruo's father, Xiao Changtian knows his son's personality more than anyone else, he knows that although his son usually doesn't talk much, he never does things that are out of proportion, since he discussed with himself to go to Jiangzhou, there must be a good reason, and his son is getting older, he doesn't want to interfere too much with his freedom, so he agreed directly without asking the reason.

"This is 500 yuan, except for buying tickets, the rest will go to Jiangzhou to keep the flowers." Xiao Changtian took out five hundred yuan from his pocket and handed it to Xiao Yuan, saying.

Xiao Yuan took the money, put it in his pocket, explained to his father, and rode out to the train station to buy a ticket.

There were as many people as ever at Nanzhou Railway Station, Xiao Yuan stood at the door of the bustling ticket hall, looked around, and was about to find a shorter queue to line up, but suddenly heard someone shouting his name.

"Xia Jiuying, why are you here?" Xiao Yuan turned his head to look over when he heard the sound, and found that it was Xia Jiuying standing not far from the gate of the ticket hall, and he was very surprised to meet Xia Jiuying here.

"I'm going to Jiangzhou on the weekend to buy tickets." Xia Jiuying said, her face was filled with a bright smile, looking at Xiao Yuan, her eyes flashed with a crystal light, and she was obviously happy to meet him.

"Heh, do you still have to buy the ticket yourself?" Xiao Yuan asked with a smile, Xia Jiuying's mother is a dignified deputy mayor, as long as she says a word, I'm afraid someone will buy the ticket soon, so he was very surprised that Xia Jiuying came to buy the ticket in person.

"My mom doesn't allow me to be special, and I'm seventeen years old, so I can do what I can do on my own." Xia Jiuying knew what Xiao Yuan meant, so he explained.

As he spoke, the two walked into the ticket hall together, lined up behind a shorter line, and slowly moved forward.

"By the way, Xiao Yuan, why are you going to Jiangzhou again?" Xia Jiuying asked.

"My mother is in Jiangzhou, and I used to have some trouble." Xiao Yuan replied.

"Oh." Xia Jiuying answered, and asked again, "By the way, I always have a question I want to ask you, the last time I saw you at Mr. Yang's birthday banquet, did you know Mr. Yang?" ”

"He's my grandfather." Xiao Yuan replied that this matter was not a secret, so he had no intention of hiding it from Xia Jiuying.

"Really?" Xia Jiuying's eyes widened and asked suspiciously.

"If it's fake?" Xiao Yuan said with a slight smile.

"Then ......" Xia Jiuying's face suddenly became a little bad, she began to turn pale, she glanced at Xiao Yuan with a complicated expression, and asked hesitantly, "Xiao Yuan, your grandfather told you...... Did you tell you about my illness? ”

ps: The second more is delivered, the green tea then goes to the third more, and today the new book list has fallen several places, the situation is a little not good, friends have flowers in their hands, and there are no collections, hurry up and help the green tea, pull the ranking up again, green tea first thank you.
