Chapter 196: explain

"Your speed is much faster than I thought, not bad."
Gu Lao nodded slightly: "What surprised me even more is that the third question you actually solved."
"Although the answer steps and ideas of the two of you are completely different, but the final answer is still the same way, who is this one?"
When Gu Lao talks, he draws one of the answer sheets.
"My." Lin also glanced and said.
"Well, your solution to the problem is relatively more straightforward, and it is quite straightforward. The third question was derived using twenty-eight formulas, like a man." Gu Lao haha ​​smiled.
"Mathematics, just like snoring, cut it with a knife and cut it until you find the answer."
Then Gu Lao looked at another one: "This, are you called Liu Wei?"
"Yeah." Liu Wei nodded slightly.
"Your problem-solving ideas are relatively more complicated, although they can't be wrong, but in terms of efficiency, they have to be slower."
"You have shared 42 formulas, and the inequalities are in opposition to the probabilities and the formulas are added. This is a bit of a superfluous addition."
After Gu Lao finished speaking, he placed two answer sheets on the table: "I want to tell you about how to achieve better results in the case of the Olympics under the basic conditions."
"The first is to be fast, the second is to be accurate."
"Fast means that your problem solving speed is faster. The criterion is that your problem solving is correct."

Generally speaking, the logical thinking direction emphasized by the Olympia title is an axis in the opposite direction. You need to find the most critical one or several points to solve the problem, and find the final answer in a broken way.

Gu Lao sat there and talked about his years of Olympic training experience and some common Olympics problem-solving skills. He also found some of the most representative topics for explanation and analysis.
Lin Yi and Liu Wei were listening there.
This explanation lasted for two hours.
Gu Lao drank his mouth and ran his throat: "I have said that, because the time is tight, there is no extra time to tell you the second time."
"As for how much you can listen to, that is your own business."
When Gu Lao finished speaking, Lao Liutou nodded at this time, looking at Lu Yifei and Liu Wei: "After you go back later, think about what you heard today in your head."
"Yes, in addition, you can go out and play now, and I will kill a few more with your teacher." After the old man finished speaking, he couldn't help but say that he started to play the chess piece and saw the old Liu head shaking his head: "You have to win, I will give up."
"That is, this plate will definitely win you!" Gu Laoyi has a well-thought-out look.
"You go out to play, you can go upstairs to see if you want to go back and go straight back, you don't need to wait for me. I don't know when to go tonight." Old Liutou looked rare and gentle.
Lin Yi and Liu Wei did not intend to stay here. After a thank you, they left the room.
When the two of them left, the old Liu head looked at Gu Lao: "Is it a seedling?"
"Yes." Gu Lao nodded.
"Which seedling is better?" Lao Liutou continued to ask questions.
Gu Lao gave him a look: "That is called Lin Yi."

Why?
Lao Liu’s face was curious, and some wanted to know his old friend’s evaluation of Lin Yi.
"The thoughts are very profound." For a long time, Gu Laozhen wrote five words.
Seeing the old Liu head is somewhat puzzled, this took the answer sheet that had just been placed on the desktop and handed it directly to the old Liu head: "Look at yourself."
The old Liu head took the past and looked at his eyes. His eyes started first and the last shock.
Gu Lao turned his eyes: "I don't know where you dug out the seedlings. Did you see the problem-solving process of the last question? That Lin's problem-solving process and the best problem-solving process I can think of are only The distance that differs by a formula."
"If he didn't write this question beforehand, then he is a full-fledged mathematical genius."
After listening to Gu Lao’s words, Lao Liu’s head laughed, but did not say anything, but began to play chess.
......
"Where are you going?" Out of the door, Liu Wei looked at Lin Yi and asked.
"Of course, go back to sleep, or else stay here."
Lin also has a faint tone. For the Olympic Games, Lin does not care at all.
The reason why I entered the competition is to get a good grade, and then go home and give it to my mom. It’s a good thing that my mom can take it out.
Zheng Jiayun was an excellent teacher for a lifetime. Because Lin Yi’s performance was too bad, there was no less discussion behind others.
My son can't teach well, why should he be a good teacher?
Every time Zheng Jiayun heard this, although there is nothing on the surface, Lin knows that his mother is still very sad inside.
Lin also pressed the elevator, and waited until the elevator came. After getting on the elevator, I didn’t think that Liu Wei took the lead and pressed the twenty-three-layer button~EbookFREE.me~ to come, go up and take a look. Ok, just relax. "Liu's tone is a bit cold, and I can't hear any emotions."
In fact, when she said this, Liu Wei’s heart was mad, but she was well concealed by her.
Liu Wei did not understand how he had just made a choice and made such a choice.
Seeing that Liu Wei has pressed the elevator, Lin will not say anything more.
When the elevator reached the 23rd floor, the door opened and the two went down the elevator.
"I have been here once in this place. From there, I can see most of the rivers, especially at night, when the street lights are all on, I feel very good."
Liu Wei walked beside Lin Yi, because the atmosphere was a bit dull, and she let her unconsciously find a topic.
The two walked all the way to the end, Liu Wei opened the door and walked into the hall on the 23rd floor.
It is already more than nine o'clock in the evening, nearly ten o'clock.
But there are still many people in the hall.

This place is usually rented out to give people some banquets and parties, and people staying in the hotel can also come to visit.

While talking, Liu Yi stepped on the marble floor and walked forward.
She stood in front of the huge floor-to-ceiling windows, across the glass, and looked at the traffic under the glass windows.
"Do you like this place? From the high point of view, it feels that the whole world has become very small and small, like a chessboard." Liu Wei turned his head and looked at Lin Yi.
By the hall lights, Liu Wei saw Lin’s sharp face.
Suddenly she found out that she didn’t know when Lin’s face looked past, and she could give a cold feeling of a knife.
