Chapter 37

Lao Xu did not disturb Lu Li and Liu Qin.

Just standing aside, he picked up the manuscripts they had written and looked at them one by one.

After reading Lu Li's, then Liu Qin's.

After reading all of them, Lao Xu was both surprised and happy. He was so happy that he could hardly express it.

There are six questions in the International Mathematical Olympiad paper. Both Lu Li and Liu Qin solved three problems in their own way. Now we are trying to solve the remaining three problems.

It's just

Lao Xu coughed lightly, reached out and knocked on the table, "not every problem has other solutions!"

"Eh?"

Lu Li and Liu Qin were awakened by Lao Xu and raised their heads together.

"Ah! Mr. Xu, here you are

Seeing Lao Xu standing in front of him, Lu Li said hello.

"No more deduction. There is only one solution to the remaining three problems. At least from the perspective of high school mathematics, there is only one solution. "

Lao Xu looked at them with a smile on his face, "you have done well enough!"

"Is there only one solution to the remaining three problems? No wonder we can't come up with a way to discuss it. "

Lu Li put away his pen and paper and gave Liu Qin a smile. "It seems that we wasted so much ink and ink. We are wasting our efforts."

"It's not in vain."

Lao Xu's eyes were full of appreciation when he looked at them. "The process of seeking new solutions, the process of derivation and calculation, is the process of reorganizing and further sublimating your knowledge. This is the most important thing. "

"Indeed

Liu Qin nodded, "in the process of doing the problem, that kind of rummaging thinking, also let me realize that I still have a lot of shortcomings. It's also a harvest. "

"Mathematics There is no end to it

Lao Xu sighed, waved to them and said, "go! Come back with me. We should pay attention to rest and don't wear ourselves out. "

"Yes, sir."

Lu Li nodded and agreed. He put away the paper on the desk and followed Lao Xu out of the library.

After walking out of the library, Lu Li found that the sun was west, and it was already afternoon.

We didn't even have lunch!

Research mathematics problem, unexpectedly to the degree of forgetting to eat and sleep?

"Didn't you have lunch?"

Lao Xu stopped, looked at them and said, "although you are young, you can't help paying attention to your body. What's the use of learning more when you're tired? "

"I'm too involved. I didn't pay attention at the moment."

Lu Li and Liu Qin are a little embarrassed.

"Get something to eat first."

Lao Xu waved his hand. "At this time, the canteen is already closed. Go to the buffet and buy some bread to fill your stomach. After eating, I go back to class, which is Take a break. "

"All right. Then we'll go first! "

After saying hello to Lao Xu, Lu Li and Liu Qin rushed to the canteen.

Looking at the figure of two people leaving, Lao Xu's face showed a smile again.

These two little guys are good seedlings! Maybe this year's Olympiad Mathematics Competition will be brilliant!

As for the two truancy, ha ha, is this a matter?

With the achievements of Lu Li and Liu Qin, the knowledge in class is too shallow for them.

Wang Min said "dating", Lao Xu more did not care. If they are solving problems every time they "date", it's OK to "date" every day.

……

After school in the afternoon, it's time for "Olympiad mathematical training".

Pick up the papers and manuscripts, Lu Li and Liu Qin once again came to the "Olympiad Mathematics Training Room" on the third floor of the experimental building.

When Lu Li and his wife came into the classroom, teacher Yang Lin was already waiting in the training room.

Seeing a stack of manuscript paper in the hands of Lu Li and Liu Qin, teacher Yang Lin was surprised.

Take so much paper? And it's full of handwriting. Did they really work out the paper?

My heart was full of doubts, and teacher Yang Lin didn't move either.

Waiting for a moment, a total of 10 Olympiad team members all arrived.

Yang Lin teacher went to the platform, looked at the crowd, said: "in the morning I sent you a paper, now, you report to me about the results."

With that, Mr. Yang Lin pointed to the seat in front of him. How many questions have you worked out? "

There are two rows of seats in the training room, five people in each row. Lu Li and Liu Qin sit in the last two positions in the right row. In the left row sat Dong Ke and four other sophomores.

The row Yang Lin was referring to was exactly the row where Dong Ke was.

"I'm sorry, teacher! I I didn't do it. "

The first boy in the left row got up and lowered his head in shame.

Then, the second student also got up, "teacher, I didn't do it. Later, I found the answer on the Internet, but I still have two questions that I didn't understand. ""I can't do it. The answer is also online. "

Even a few students can not answer, almost all the answers are found on the Internet.

When it was Dong Ke's turn, he got up and said, "I made two

As soon as these words came out, Lu Li and Liu Qin's faces changed. They looked at each other and saw the shock in each other's eyes.

We can't do any questions, but we will only do it after reading the answers. How can Dong Ke do two questions? How could he be so strong?

The report is still going on. Lu Li's classmates in this row all answered, "I can't do it. I can't find the answer online."

When it was Lu Li's turn, he got up and said, "I couldn't do it at first. After I got the answer, I studied it, and then I did three questions in my own way. "

"Me too."

After Lu Li finished, Liu Qin also stood up and answered.

Hearing Lu Li and Liu Qin's reply, the classroom was quiet.

Those students who "seek answers online" are full of horror. We haven't fully understood the answer yet. Have you developed a new method to solve the problem?

Dong Ke's face also changed. He turned to look at Lu Li and his eyes were filled with incredible horror.

Dong Ke has done this paper for a long time, and Mr. Yang Lin has explained it to Dong Ke. This time, Dong Ke worked out two problems with his own way of thinking.

Now, Lu Li and Liu Qin have made three questions in their own way?

They got the papers only one day, and I was studying these topics a month ago! How can they be so strong?

Teacher Yang Lin was more shocked than others.

With the difficulty of this set of papers, it's normal not to be able to do it. Find the answer online, which is also expected by Mr. Yang Lin.

Even if you find answers online, it's not easy to read and understand them in a few hours during the day.

Originally, Mr. Yang Lin expected that Lu Li and Liu Qin could understand the answers and understand the answers at most.

Now They even said that they had solved three problems in their own way and in a new way!

There are only three questions in this set of test paper that can have other solutions, and there are no other solutions for the remaining three questions. Lu Li, they have reached the limit.

Dong Ke had done this set of papers a month ago, and I explained it to him. Only now can he solve two problems in his own way. But Lu Li and Liu Qin made three.

How can they be so strong?

No wonder they dare to call themselves "genius" in front of me. It turns out that they really have this strength!
