Chapter 309

"Professor!"

"Your explanation is very wonderful, every process is very careful, and there is no slippage." Xu said seriously: "I just came up with a topic, which requires a very solid mathematical foundation and a strong logical thinking ability. I hope you and the members of the team will try to do this problem."

"Well?"

"Let me see." The professor asked curiously.

Xu handed the paper to the professor.

After a moment,

the professor, who had been relaxed, seemed serious.

"Cough!"

"When did you ask the question?" The professor asked with a serious look.

"Just..."

"I just came up with a topic, which needs logical thinking ability..." Xu mang said with a smile: "it's no use just to have a solid mathematical foundation. If you don't have a strong mathematical thinking, this problem is a little difficult to solve."

"..."

"is this the question you just came up with?" Professor Leng for a moment: "casually think out?"

"Yes

"Professor... Do you think this question is suitable for the contestants?" Xu asked.

The professor nodded and said in silence, "very suitable!"

"So..."

"I'll solve it first." The professor said, "then let the students understand. What do you think?"

"Oh."

As the saying goes,

Xu mang sat back in the last row.

Looking at the young man's back, the professor was a little curious. If all this was true and he didn't lie, then his mathematical talent would be extraordinary. Why didn't he take part in the competition?

It doesn't make sense!

Well,

ask later.

The professor began to solve Xu's problem, but soon he found the problem. Although it was an algebraic problem, he couldn't find the breakthrough.

After that, the professor tried a complicated solution. Finally, it took 17 minutes, and then based on the answer, he got a relatively simple process. At this time, the class ended at noon.

Seeing Xu Mang's intention to leave, the professor stopped him in a hurry.

"Classmate!"

"Wait a minute!" The professor called out to Xu Mang, "will you come back this afternoon?"

"Er..."

"come on!" Xu mang nodded and said with a smile, "the professor has untied it?"

"Untied."

"But I want to know what your answer is. Let's talk about it this afternoon." Said the professor.

"Oh."

At noon,

at noon,

Xu Mang and Yang Xiaoman had dinner in the school canteen. The five were curious about the dialogue between Xu Mang and the professor. However, even if he asked, Xu mang kept smiling and did not talk to anyone about his relationship with the professor, including Yang Xiaoman.

In this regard,

Yang Xiaoman was very unhappy and a little upset.

It's mainly a little humiliating... It's my boyfriend, but I keep it secret... I'm still in front of so many people.

In the nearby Starbucks,

Yang Xiaoman ordered a cup of hot fruit tea and sat on his chair without saying a word.

Yang Xiaoman: (~ ~)

"..."

"how?" Xu looked up and asked, "who are you bullying? Tell me... Beat him to pieces

Yang Xiaoman glanced and said angrily, "well, you smoke yourself."

"..."

"is it me Xu mang suddenly realized that he had no choice but to say, "I'm quite honest today..."

"hum!"

"You let me down in front of others." Yang Xiaoman said angrily.

Xu mang frowns, calculate the day... Today seems to be Xiaoman to relatives of the day, can not afford to... Last time suffered a big loss.

In the face of a woman who comes to her relatives, the best solution is to keep silent and endure her small emotions, because at this time, no matter what you do is wrong, there is no way... There will always be a few days of restlessness every month.

Crackling and complaining, Xiaoman got the emotional release.

"Little man?"

"Eh?"

"Are you... Relatives?" Xu mang asked cautiously.

"..."

"it seems that I came in the middle of the night yesterday, which scared me to death in the morning." Yang Xiaoman suddenly asked mysteriously, "how can you calculate my days so clearly? Is there a bad attempt? ""No!"

"Ha ha... Tea, tea."

Soon,

it was afternoon time.

Xu Mangchong in the front, happily came to the training classroom, found that the professor has been present.

"Hello, professor."

"Coming?" Seeing Xu Mang's arrival, the professor nodded and said, "can you take a look at my problem-solving process?"

"Oh..."

Xu mang picked up the professor's problem-solving process, looked at it carefully, and there were basically no mistakes. Then he said seriously: "Professor... You are worthy of being a big man in the field of mathematics. You are absolutely correct and there are no mistakes."

"At first I couldn't work it out, then I went around a big circle, and finally I got the simplest process." The professor looked at Xu Mang and said solemnly, "I'm impressed by your ability to work out questions."

"Ha ha..." Xu mang smiles: "I am just a student."

"What's your name..."

in the middle of the professor's speech, Yang Xiaoman came to the classroom. Immediately, the professor did not go on and said in silence, "let the players do the questions first, and then you can help them analyze the process and solution ideas in person."

"Oh."

Xu mang returned to his last row of positions, lying directly on the table.

"Cough!"

"I'll give you an hour to solve a math problem!"

The professor wrote down this question on the blackboard.

Let Z be used to express the set of all integers, and find all functions f: Z → Z. for any integers a and B, there is f (2a) + 2F (b) = f (f (a + b))

at this time,

at this time,

everyone present is confused, including Yang Xiaoman.

This...

what function is this?

After that, the five players started their own problem-solving process, but the process was very difficult because the form of the function could not be determined at all.

Because they can not find the beginning, the five people almost at the same time into a dilemma can not move forward, now they do not even know what this function is, the following is a more confused and confused.

Who gave the title?

Kill him!

Wait a minute,

in the morning... It seems that there is a guy who is very close to the professor?

At this time,

everyone thinks of one person, Xu mang.

Isn't it Xu Mang's problem?

The more you think about it, the more likely it is. Otherwise, Xu mang won't discuss with the professor for a long time. How angry... What is he doing!

No!

Since this topic was written by Xu Mang, isn't his mathematical ability already...

thinking about it,

except for Yang Xiaoman, the other four people take a breath. Xu mang is hidden so deeply that he may not be the real main player? If so good, why not be selected into the team?

Not scientific!

Very unscientific!

For a long time,

five minutes later,

the five people are still in a state of confusion. They have tried countless function forms, but still have no hope.

Ten minutes later,

the five people still had nothing to gain. Facing this unknown function, they began to despair.

After 15 minutes,

Yang Xiaoman seemed to get some inspiration, so she began to write hard and make a new attempt.

Forty five minutes later,

inspired, the four began to write. Yang Xiaoman had just solved this problem, but the process was very complicated. It took three pieces of white paper to solve the problem alone.

Finally,

at the end of the specified time, the five handed in their answers to the professor.

Under the correction,

the professor found that only two people were correct, and only Yang Xiaoman was the one who was closest to the reasonable process, but only the closest and did not fully meet the requirements.

Gap!

This is the gap!

At this time,

the professor called Xu mang out of the corridor. He wanted to know who this student from Fuda was and why he didn't take part in the competition.

"Classmate?"

"You... What's your name?" Asked the professor.

"Me?"

"Xu Mang, a student of physics at Fuda." Xu mang said with a smile.

"..."

"are you Xu mang?" The professor was stunned for a moment and laughed: "I should have guessed it was you. This is my fault."

As the words fell,

the professor suddenly stiffened his face, glared at Xu Mang and said, "why don't you take part in the competition? If you are here, we can still raise our ranking. The first place is not a problem, is it a retreat? ""No

"It was the tournament that banned me." Xu sighed blankly and said in silence, "they said that I did not meet the requirements and could not participate in the competition. Once I participated, it would make the game no suspense, so they directly banned me..."

hearing this,

the professor patted Xu mang on the shoulder and said helplessly, "I started to play the so-called restriction tactics again."

Meanwhile,

Yang Xiaoman is being bombarded by his teammates.

"Xiaoman, why is Xu mang so strong?"

"Yeah... Why didn't he compete?"

"Are you afraid?"

"How high is Xu Mang's mathematical talent?"

Facing the tide of questions, Yang Xiaoman didn't know how to answer for a while, but said with a wry smile: "this guy is... A smart fool."

In Yang Xiaoman's eyes, Xu mang is a fool. He is so stupid that he can't use words to describe him. When he met for the first time, the image of the fool was deeply imprinted in Yang Xiaoman's heart and could not be dispersed for a lifetime.

And smart... No more words.

"..."

"..."

"..."

"..."

this answer obviously does not meet the requirements of the four people, because the answer is full of love, and a little suspected of spreading dog food.

At this time,

the professor and Xu mang came in. They stood in front of the platform. The professor said, "I guess you all guessed that the problem that baffled all of you was put forward by this student, and this student is from Fuda University, called Xu mang. You should have heard of it."

"Remarkable achievements have been made in the field of physics, with two academic papers in the first area of SCI." The professor said, "but don't forget that Xu's mathematical talent is the same as his physics."

"Xu mang?"

"Explain to them how to solve this problem, and I'll go to class by the way." The professor smiles at Xu Mang and then walks to the stage.

Yang Xiaoman is going to say, Professor... You will regret it. As a result, the professor went directly to the stage without any melancholy.

Looking at the smiling Xu mang on the stage, Yang Xiaoman's head is big... Don't make the team-mates autistic, it can't hurt!

"Students

"It's a very basic question. There's no difficulty at all." Xu mang said with a smile: "it's a question for giving points."

As soon as the voice dropped,

the four students present were very angry, and they planned to carry knives.

At this time,

Yang Xiaoman: (° ー)

finished,

he is going to start!
