Chapter 195: 3 Questions

Lin Yi followed the elevator, and the elevator stopped at the 22nd floor.

"I live on the 22nd floor, and the next floor is the leisure area of ​​Sunyao Blue Ocean. Your two students can go up and play later."

Mr. Gu got out of the elevator, walked to the door of a room, and opened the door: "Come in."

Inside the door, the room is very large and spacious. It has a layout of one bedroom, one living room and one bathroom. Outside the floor-to-ceiling windows, you can see the street view and the city lights are twinkling.

The ground is covered with a thick mutton blanket, and it feels soft when you step on it.

"Old Liu, it's really not me talking about you. If you're not brain-dead, why are you always making things difficult for yourself? Wouldn't it be nice to go to Yanjing to be a professor with me?" Gu Lao entered the room , went to make a pot of tea.

"Don't talk about that, you know the main purpose of coming this time." Old Liu shook his head.

"I know, then you two, come here first." Gu Lao nodded and greeted Lin Yi and Liu Luran.

Afterwards, Mr. Gu took out a stack of draft paper and two pens from his bag. Then, he picked up the pen and sat at the table. After thinking about it, he picked up the pen and quickly wrote down three questions on the paper.

"I still don't know how the two students you brought are doing math. You should do this question first, three questions." Gu Lao gave the questions to Lin Yi and Liu Luran respectively.

Lin Yi, who took the question, glanced quickly.

"To be honest, I don't know what the Olympiad questions are. These three questions are written to judge your mathematical ability. If you can solve two questions, I will have a good talk with you about the Olympiad. A problem with thinking." Gu Lao glanced at the time: "I'll give you an hour and a half."

After finishing speaking, Mr. Gu went to Mr. Liu: "Let the two of them write the questions there. It's been a long time since we two old guys have been able to play a good game. My chess is ready."

Gu Lao was rubbing his fists while talking, and took out a chess set from the cabinet.

"You, you, are you unconvinced when you lost to me before?" Seeing chess, old Liu was very happy.

"No, I haven't had a good meal for several months since I lost to you last time. This time, I will definitely kill you!" Gu Lao vowed.

The two sat down to play chess.

Lin Yi held a pen in one hand and looked at the three questions in front of him.

The first question is about the application of trigonometric functions, the second question is about the structure of sequence, and the third question is about the set structure of probability methodology that integrates inequalities and conic sections.

Three questions, from easy to difficult.

Lin Yi didn't hesitate either. After thinking for a moment, he picked up a pen and began to write and draw on the manuscript paper.

Liu Luran, who was sitting opposite Lin Yi, took a look at Lin Yi.

The difficulty of these three questions is not low. Seeing Lin Yi's earnest expression on solving the questions, Liu Luran had to admit that she was still a little surprised.

Lin Yi got high marks in the school's previous math problems, and then qualified for the Olympiad. This matter has always been a mystery in Liu Luran's heart.

She couldn't imagine why Lin Yi's math grades would suddenly rise, stand out from the crowd, and this time he was brought to find Mr. Gu by the old head Liu, becoming a dark horse.

But soon, Liu Luran got rid of the distracting thoughts in her head and began to concentrate on solving the problem.

Over there, Gu Lao and Lao Liu Tou were drinking tea and playing chess at the same time. They were inseparable from each other.

Mr. Gu glanced at the two people who were sitting on the other side writing the question, lowered his voice, and looked at the chessboard: "I have never seen you bring students to me before, why is it an exception this time?"

"It's rare to meet a good seedling. I can help as much as I can. I have been patronizing teaching all my life. When I am old and about to retire, I realize that something seems to be missing." Old Liu Tou picked up a horse and flew The opposite cannon.

"It's really rare. There is still a little guy who can become a good seed in your mouth. If the two of them are really so talented, why don't you give them to me? I can still talk in Huaqing Mathematics Department , when the time comes to press down on their scores and let them come in, or after the provincial-level Mathematical Olympiad, I will work harder and send them to the National Mathematical Olympiad to get a ranking, and then how about recruiting them directly?" Gu Lao picked up a car and drove forward Eat a pawn.

"It also depends on whether they are willing or not." Old Liu shook his head slightly: "Their path is always chosen by themselves. At most, I can only help the staff."

After finishing speaking, Old Liu's horse went one step further and landed directly in front of Shuai on the opposite side.

General, pump the car.

Gu Lao’s face was solemn for a while: "That can’t be done, I think, a good seedling should be treated like a good seedling, but I don’t know whether it is a real seedling or a fake seedling. Doing mathematics, hard work determines the lower limit of achievements that can be achieved. , talent determines the upper limit."

"It's your turn, don't think I'll make you regret your move if you put on such a serious look, hurry up, don't talk nonsense." Old Liu's brows were crooked, not in a good mood.

"Hey, why are you so impersonal? We've been friends for so many years, and you won't give up a single move." Gu Lao was a little discouraged, and abandoned his car to protect his handsomeness.

Old Liu Tou took the opportunity and the pawn on the right crossed the river.

"There is no retreat for pawns crossing the river. I don't know how long I can live. If I can eat one more chess piece from you and win one more game of chess from you, that would be great." Old Liu Tou laughed.

Over there, Lin Yi put down the pen in his hand.

Two minutes after Lin Yi put down his pen, Liu Luran also put down his pen.

She let out a foul breath and raised her head, only to realize that Lin Yi in front of her had stopped answering questions at some point.

"Finished?" Liu Luran was stunned and asked.

"Yeah." Lin Yi nodded and stood up.

The two brought the question to the two old men who were fighting over there.

Seeing Lin Yi and Liu Luran approaching, Mr. Gu first waved his hand to signal them to stop talking, and then started a final fight with Mr. Liu.

On the battlefield, the fighting was brutal.

At the end of the fight, Old Liu used two pawns to force Old Gu's handsome man to death in the palace.

"Sigh, it's wrong to lose this game." Gu Lao was in pain for a while. If the rook didn't die just now, there was still a chance to fight. Now the game is in the middle of the game, and there is no way to kill even two pawns.

Old Liu Tou just smiled and didn't speak.

Gu Lao raised his head, looked at Lin Yi and Liu Luran standing there, and then looked at the time.

"Forty-five minutes? Are you done?" Gu Lao was stunned.

Seeing Lin Yi and Liu Luran nodding, he took their answer sheets and glanced at them.

First, they roughly scanned the answers to the first two questions, and then looked at the answer to the third question.

Gu Lao's eyes gradually brightened, occasionally he was a little pensive, and finally he was a little more approving.
