Chapter 24 Why can he take leave?
"To be honest, I am lucky to know you. You teach better than our math teacher." After the auditors returned to their seats, Lin Haoming suddenly said seriously: "There is absolutely no falsehood in this statement."

Then he vowed: "I believe you will definitely be able to join the national training team in the final next month."

He has a clear understanding of his own math level. It can be said that he has reached his limit to be able to enter the provincial team. If nothing unexpected happens, his result in the finals will probably be at the bottom.

Winning a national silver medal is considered an exceptional performance.

But after sitting next to Xu Yuan these days and asking him for advice from time to time, he could feel that he had improved a lot.

The complex questions that I found difficult before can now be handled easily.

Because of this incident, he also understood more clearly why Xu Yuan was able to make it out of a small county town.

His talent in mathematics is truly amazing.

No wonder Professor Qi gave such affirmation at the beginning of the training camp.

For this reason, whenever he saw his classmates in the competition class going to Professor Qi Tongxiang to ask questions, he felt deeply sorry and regretful for them.

After all, Qi Tongxiang's level of mathematics was much higher than theirs, so what he said was difficult to understand.

It is far less simple and easy to understand than Xu Yuan's.

Xu Yuan had no idea what Lin Haoming was thinking, and of course he didn't care.

He just felt that Lin Haoming's personality was quite similar to Yang Bin and Wang Yongjie.

Get along well with him.

This is how we became more familiar with each other as temporary deskmates.

Hearing this, he just casually said, "Why do you suddenly become so emotional?"

Qi Tongxiang did not give a lecture during the evening study session today, but asked everyone to plan their own time.

As for himself, he wandered around the classroom.

It is convenient for students to ask questions.

When he walked to Xu Yuan's side, a familiar voice suddenly came to his ears.

"Professor Qi."

When Qi Tongxiang found out that it was Xu Yuan who spoke, he couldn't help but feel happy.

Then he stopped and asked, "Is there something you don't understand?"

He saw from the league test papers that Xu Yuan was a good prospect, but it was only after interacting with him for the past few days that he truly discovered Xu Yuan's talent in mathematics.

It can be said that it was far beyond his expectations.

Among all the training team members, only Xu Yuan can fully keep up with his pace and has quick thinking.

The basics are clear at a glance.

This made it difficult for him to find an opportunity to give Xu Yuan some special treatment in private.

This should be considered a good thing, but I can't help feeling uncomfortable.

Therefore, when he heard Xu Yuan calling him, he subconsciously thought that the other party had finally encountered an unsolvable problem, and his mood instantly became cheerful.

But this joy did not last long, because I heard Xu Yuan say: "Professor Qi, I want to take a leave tomorrow to go to my parents' house." It was not about asking for help with math problems.

Tomorrow is Saturday, so he thought about taking a day off to visit his parents.

The reason I didn’t ask for leave in the past few days was that I was afraid that the class time would be over and make my parents worry again.

After listening to Xu Yuan's request, Qi Tongxiang's mouth twitched slightly.

Although I felt a little disappointed, I finally agreed after a little thought.

"I've approved your leave. Remember to submit the application to Coach Zhang."

"Thank you, Professor Qi." Seeing that his goal was achieved, Xu Yuan quickly expressed his gratitude.

Everything was normal up to this point, but the next second, a discordant murmur was heard coming from the seat next to me, which immediately attracted a lot of attention.

"Why can he take leave?"

Xu Yuan looked in the direction where the voice came from, and a figure wearing the Luyang No. 1 Middle School uniform appeared in his field of vision.

He wore a pair of black-framed glasses and had a standard student hairstyle. He remembered that the other person was called Li Mingliang, and they were both members of the provincial team.

It was the first time that Li Mingliang was stared at by so many pairs of eyes after entering the training camp.

Suddenly seemed a little cramped.

But when he thought about Professor Qi's attitude towards Xu Yuan these days, he couldn't help but feel a little unbalanced.

We are all members of the provincial team, why is Xu Yuan so valued?

Just now, when I heard Qi Tongxiang approve Xu Yuan's leave so easily, I couldn't help but mutter, I never thought that everyone in the class had such good hearing.

Faced with this situation, he prepared himself mentally and then repeated the sentence again.

"Professor Qi."

"According to regulations, you are not allowed to take leave during the training period."

"You are right. In that case..." Qi Tongxiang first affirmed Li Mingliang's words, and then walked quickly towards the podium.

Xu Yuanyuan knew that he could not take leave during the training period, so he specifically applied to Qi Tongxiang.

But at the moment he didn't know whether the leave could be approved, so he could only wait and see what Professor Qi would do next.

Soon Qi Tongxiang came to the podium, picked up a piece of chalk and started writing quickly facing the blackboard. Only then did everyone realize that this was a math problem.

"Let a, a…, a, b, b…, b be real numbers, and c, c…, c be positive real numbers,"

"Proof: (∑i,j=1a_ia_j/c_i+c_j)..."

Just as everyone was subconsciously thinking about this question, Qi Tongxiang turned around and explained with a smile.

"This is a test question from an overseas test. It's about proving an inequality. Whoever solves it first will get a day off."

"It makes sense."

After saying this, he didn't care about the expressions of the students below the stage, he just moved a chair and sat next to them, waiting patiently.

Then everyone took out their scratch papers and started calculating, wanting to be the first to solve the problem.

Especially Li Mingliang and other members of the provincial team.

After all, being able to have Professor Qi set the questions personally is a good opportunity to prove my ability, and the promised vacation has become secondary.

Seeing the expressions of the students below the stage, Qi Tongxiang was not anxious at all.

When he first saw this question, he also spent a lot of effort on it. If his thinking was slightly deviated, he would fall into misunderstanding.

Then they go further and further wrong.

So he didn't think anyone could solve it in a short time.

But less than two minutes after this thought appeared in his mind, he saw Xu Yuan suddenly stand up and answer.

"For this problem, we just need to show that the terms on the left are all non-negative."

It was just a casual remark, but a big question mark appeared in everyone's mind at the same time.

what's the situation?
I haven't even understood the question yet, and you've already solved it?

Qi Tongxiang looked a little disappointed when he heard this, but then he seemed to have thought of something and turned back to look carefully at the question on the blackboard again.

After staring for a few minutes, he stood up with a look of joy on his face.

"Wonderful!"

“This is a brilliant idea.”

I highly praise Xu Yuan's approach to solving the problem.

At first he thought Xu Yuan had made a mistake, but after calculation he found that this idea was more suitable and sophisticated than his method of solving the problem. The key point was that Xu Yuan only took less than two minutes.

If Xu Yuan's performance in the past few days made him satisfied, then now it was a huge surprise.

　Please collect and read it. You may vote for it. It would be even better if you can give me a reward.
