Chapter 196 Explanation

"Your speed is much faster than I imagined, not bad."

Gu Lao nodded slightly: "What surprised me even more is that you all solved the third question."

"Although the answer steps and thinking of the two of you are completely different, the final answer is still the same. Whose answer is this?"

Gu Lao took out one of the answer sheets while talking.

"Mine." Lin Yi glanced and said.

"Well, your way of solving the problem is relatively more straightforward, and it is much more straightforward. The third problem was deduced with 28 formulas, like a man." Gu Lao laughed.

"Mathematics is like fighting a war. Take a knife and cut forward until you break through the encirclement and find the answer."

Then Elder Gu looked at another one: "This, your name is Liu Luran, right?"

"En." Liu Luran nodded slightly.

"Your problem-solving ideas are relatively more complicated. Although you can't be wrong, in terms of efficiency, you have to slow down."

"You used a total of forty-two formulas, and you listed the formulas as opposed to inequalities and probabilities, which is a bit superfluous."

After Mr. Gu finished speaking, he put the two answer sheets on the table: "What I want to tell you is about how to achieve better results in the Olympiad with a solid foundation."

"The first is to be fast, and the second is to be accurate."

"Fast means that your speed of solving problems must be fast, and the criterion is that your thinking about solving problems must be correct."

"Generally speaking, the logical thinking direction emphasized by the Olympiad questions is an axis in the opposite direction. You need to find the most critical one or several problem-solving points from it, and find the final answer in a point-by-point manner."

Mr. Gu sat there and talked eloquently, telling all his years of Olympiad training experience and some common Olympiad problem-solving skills, and at the same time found a few most representative problems for explanation and analysis.

Lin Yi and Liu Luran were listening there.

This lecture lasted for two hours.

Gu Lao took a sip of water and moistened his throat: "I've said everything I need to say, because time is tight, and I don't have extra time to tell you a second time."

"As for how much you can listen to, that's your own business."

After Mr. Gu finished speaking, Old Liu also nodded at this time, and looked at Lu Yifei and Liu Luran: "After you go back later, think about what you heard today in your head."

"Yes, besides, you can go out to play now, and I will play a few more games with your teacher." After Gu Lao finished speaking, he couldn't help but start to place chess pieces, and Lao Liu shook his head: "You have to win before I give up."

"That's right, you'll definitely win this game!" Mr. Gu looked confident.

"Go out and have fun. You can go upstairs to have a look. If you want to go back, you don't need to wait for me. I don't know when it will be down tonight." Old Liu's face was rare and gentle.

Lin Yi and Liu Luran had no intention of forcing them to stay here, so after thanking them, they left the room.

After the two left, Old Liu looked at Gu Lao: "Is it Miaozi?"

"Yes." Gu Lao nodded.

"Which seedling is better?" Old Liu continued to ask.

Gu Lao glanced at him: "That one is called Lin Yi."

"Why?" Old Liu looked curious, and wanted to know what his old friend thought of Lin Yi.

"The thought is very profound." After holding back for a long time, Gu Lao choked out five words.

Seeing that Old Liu was a little puzzled, he picked up the answer sheet that had just been placed on the table, and handed it to Old Liu directly: "Look for yourself."

Old Liu took it and looked at it twice. His eyes were stunned at first, and then shocked at last.

Gu Lao rolled his eyes: "I don't know where you dug the seedlings,

Did you see the problem-solving process for the last question? The problem-solving process named Lin Yi is only one formula away from the optimal problem-solving process I can think of. "

"If he hadn't written this problem beforehand, he would be a complete mathematical genius."

After hearing Gu Lao's words, Lao Liu laughed, but didn't say anything, but started to play chess.

...

"Where are you going?" After leaving the room, Liu Luran looked at Lin Yi and asked.

"Of course I go back to sleep, otherwise why stay here."

Lin Yi's tone was indifferent, in fact Lin Yi didn't care about the Olympiad or anything like that.

The reason why I participated in the competition is to get a good result, and then go home to show my mother, at least it is something that my mother can brag about.

Zheng Jiayun has been an excellent teacher all his life, but because of Lin Yi's poor grades, many people talk about it behind his back.

My own son can't teach well in studies, so why should he be an excellent teacher?

Every time Zheng Jiayun heard this, although it didn't look like anything on the surface, Lin Yi knew that his mother was still very sad deep down.

Lin Yi pressed the elevator, and when the elevator arrived, after getting on the elevator, what he didn't expect was that Liu Luran pressed the button for the 23rd floor first.

"It's already here, go up and take a look before leaving, as if you're relaxing." Liu Luran's tone was a little cold, and no emotion could be heard.

In fact, when Liu Luran said this, her heart was beating wildly, but she concealed it well.

Liu Luran also didn't understand why she made such a choice just now.

Seeing that Liu Luran had already pressed the elevator, Lin Yi didn't say anything else.

When the elevator reached the twenty-third floor, the door opened and the two got off the elevator.

"I've been to this place once before, and I can see most of Jiangcheng from there. Especially at night, when all the street lights are on, it feels very good."

Liu Luran walked beside Lin Yi, because the atmosphere was a bit dull, she unconsciously found some topics.

The two walked all the way to the end, Liu Luran opened the door and walked into the lobby on the 23rd floor.

It's already past nine o'clock in the evening, almost ten o'clock.

But there are still many people in the hall.

"This place is usually rented out to hold some banquets and parties for people, and people staying in the hotel can also come up for sightseeing."

While talking, Liu Luran stepped on the marble floor and walked forward.

She stood in front of the huge floor-to-ceiling windows, looking at the busy traffic under the glass windows from a distance.

"Would you like such a place? Looking down from a very high place, it feels like the whole world has become very small, like a chessboard." Liu Luran turned her head and looked at Lin Yi beside her.

Through the hall light, Liu Luran saw Lin Yi's sharp-edged face.

She suddenly discovered that at some point, Lin Yi's face could give people a cold feeling like a knife's edge.
