I really don't want to lie down and win

"Thank you, Professor." Xu Mang said solemnly.

at this time,

The five members of the representative team looked at Xu Mang in bewilderment, especially Yang Xiaoman.

what's the situation?

What is he here for?

It seems that if you take out some kind of ID card, you can walk in with a big swagger.

Xu Mang quietly walked to Lan Xiaoai's side. Looking at the practice questions she had done, Xu Mang couldn't help nodding his head in praise. He deserved to be among the top five contestants in the National College Students Math Competition. This problem-solving idea is very clear.

Then,

Xu took another look at Lan Xiaoai's other practice questions and the process of solving them. Although there were a few flaws, overall it was quite good.

soon,

Xu Mang came to Li Wei's side again, took a look at his practice problem solving process, and had to praise them, these people were very nice.

at last,

Came to Yang Xiaoman's side.

"Hey hey hey..."

"Didn't think of it?" Xu Mang whispered softly.

"idiot!"

"What are you doing?" Yang Xiaoman lowered his voice, stared at Xu Mang and asked, "It's almost time to leave!"

"Don't worry."

"I'm just listening to the lectures."

words fell,

Xu Mang found a seat in the last row, then took out a pen and paper, and began to listen to the professor explain the next classic practical problem.

This is an extremely complex algebra problem,

There was nothing wrong with the professor's explanation, and Xu Mang didn't find anything that needed to be revised.

I have to sigh,

None of the professors who can train the PUMaC representative team is a good stubble, and they are all quite terrifying.

but...

Xu Mang was a little helpless. The professor's training method still adopted the method of brushing the questions. It is important to brush the questions, but the math thinking cannot be developed by brushing the questions, such as this logical thinking ability.

Scratching questions may be helpful for competitions, but it does not help mathematics research.

Xu Mang thought for a while,

Decided to give everyone present a question to make them doubt life. Of course, the professor cannot be doubted about life. He can doubt it for an hour at most, while Xiaoman may doubt it for a long time, and the others just...

Thinking of this,

Xu Mang wrote a topic on the paper.

After the professor finished explaining and the members started to do similar exercises, Xu Mang walked to the professor with the paper of the questions.

......

Chapter 3 is a sub-question! (2/3)

"professor!"

"Your explanation is very exciting, every process is very careful, and there is no sloppiness." Xu Mang said seriously: "Just now I came up with a question, which requires a very solid mathematical foundation and strong logical thinking ability, I hope that you and the members of the representative team will try to solve this problem."

"Ok?"

"Let me see." The professor asked curiously.

words fell,

Xu Mang handed the paper to the professor.

After a while,

The professor who was originally relaxed looked a little serious now.

"Cough cough!"

"When did you come up with the question?" the professor asked seriously.

"just..."

"I came up with a question randomly. This question requires logical thinking ability..." Xu Mang said with a smile: "It's useless to have a solid mathematical foundation. If you don't have a strong mathematical thinking, this question is a bit difficult." Incomprehensible."

"..."

"Did you come up with this question just now?" The professor was stunned for a moment: "Just came up with it casually?"

"Yup!"

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

The professor nodded and said silently: "Very suitable!"

"so..."

"Let me solve it first." The professor said, "Then let the participating students solve it. What do you think?"

"Oh."

words fell,

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 was not lying, then his mathematical talent would be extraordinary. Why didn't he participate in the competition?

It doesn't make sense!

That's it,
