Chapter 37: They are so strong?

　　　　 Old Xu did not disturb Lu Li and Liu Qin.
　　 just stood aside, picked up the manuscript paper that the two had written, and looked at it one by one.
　　 After watching Lu Li's, look at Liu Qin's.
　　 After reading all of them, Old Xu was surprised and delighted, and he was so pleased and happy that it was beyond words.
　　 There are six questions in the International Mathematical Olympiad. Both Lu Li and Liu Qin used their own methods to solve three problems again. Now working hard to overcome the remaining three problems.
　　 just...
　　 Old Xu coughed lightly, reached out and knocked on the table, "Not every problem has other solutions!"
"Uh?"
　　 Lu Li and Liu Qin were awakened by Old Xu and raised their heads together.
　　 "Ah! Teacher Xu, you are here!"
　　 Seeing Old Xu standing in front, Lu Li and the two hurriedly said hello.
　　 "There is no need to continue the derivation. There is only one solution for the remaining three questions. At least from the perspective of high school mathematics, there is only one solution."
　　 Old Xu looked at the two with a smile, "You have done well enough!"
　　 "Is there only one solution to the remaining three questions? No wonder we discuss it and we can't figure it out."
　　 Lu Li put away the pen and paper, and smiled at Liu Qin, "It seems that we have wasted so much effort."
　　 "This is not a waste of effort."
　　 Old Xu looked at the two with admiration, "The process of seeking new solutions and deriving calculations is the process of reorganizing and further sublimating what you have learned. This gain is the most important."
　　 "Indeed!"
　　 Liu Qin nodded, "During the process of doing the question, the kind of thinking about intestines also made me realize that I still have many shortcomings. This is also a gain."
　　 "Mathematics... never ends!"
　　 Old Xu sighed, waved to the two of them, and said, "Go! Come back with me. The way of civil and martial arts is relaxed, and you should pay attention to rest and don't tire yourself out."
　　 "Okay, teacher."
　　 Lu Li nodded in agreement, put away the manuscript paper on the table, and followed Old Xu out of the library.
　　 After walking out of the library, Lu Li discovered that the sun was westward, and it was already afternoon.
　　 We didn’t even eat lunch!
　　 Studying mathematics problems, has it reached the point of forgetting to sleep and eat?
　　 "Did you not eat at noon?"
　　 Old Xu stopped, glanced at the two of them, and exhorted: "Although you are young, you must not pay attention to your body. If your body is exhausted, what's the use of learning more?"
　　 "Too devoted, I didn't pay attention for a while."
　　 Lu Li and Liu Qin are a little embarrassed.
　　 "Go eat something first."
　　 Old Xu waved his hand, "At this time, the cafeteria was closed long ago. First, go to the canteen to buy some bread to fill up the stomach. After eating, go back to class, be it... take a break."
　　 "Okay. Then let's go there first!"
　　 greeted Lao Xu, and Lu Li and Liu Qin rushed all the way to the canteen next to the canteen.
　　 Looking at the two leaving figures, there was another smile on Old Xu's face.
　　 These two little guys are both good seedlings! Maybe, this year's Olympiad will be able to shine!
　　 As for the two people skipping class, hehe, is this a problem?
　　 With the results of Lu Li and Liu Qin, the knowledge taught in class is too shallow for them.
　　 Wang Min said "dating", and Old Xu didn't even care. If they were solving problems every time they "dated", it would be okay to "date" every day.
　　……
　　 After school in the afternoon, it is the time for the "Olympics Training".
　　 Picking up the test paper and manuscript paper, Lu Li and Liu Qin once again went to the "Olympics Training Room" on the third floor of the laboratory building.
　　 When Lu Li and the two walked into the classroom, Teacher Yang Lin was already waiting in the training room.
　　 Seeing the stack of manuscript papers held by Lu Li and Liu Qin, Teacher Yang Lin's eyes flashed with surprise.
　　 Take so much manuscript paper? And it's still manuscript paper full of handwriting. Did they really solve this test paper?
　　 was full of doubts, and Teacher Yang Lin didn't make a move.
　　 After waiting for a while, all ten Olympiad players arrived.
　　 Teacher Yang Lin walked up to the podium, glanced at everyone, and said, "I sent you a test paper in the morning, and now, you will report the result to me."
　　 After finishing speaking, Teacher Yang Lin pointed to the front seat, "Start from here. How many questions have you completed?"
　　 There are two rows of seats in the training room, each with five people. Lu Li and Liu Qin sat in the last two positions on the right. Sitting in the left row are Dong Ke and four other high school sophomores.
　　 The row that Yang Lin pointed to is exactly the row where Dong Ke is.
　　 "Sorry, teacher! I... didn't make it."
　　 The first boy in the left row got up and lowered his head with shame.
　　 Then, the second classmate also got up, "Teacher, I didn't do it either. Later I found the answer on the Internet, but I still didn't understand the answers to two questions."
　　 "I can't do it either. The answer is also found online."
　　 Even a few classmates couldn't answer, almost all the answers were found online.
　　 When it was Dong Ke's turn, Dong Ke stood up and replied, "I made two."
　　 As soon as these words came out, Lu Li and Liu Qin's expressions changed. They looked at each other, and both saw the shock in each other's eyes.
　　 We don’t know a single question. We will only do it after reading the answers. This Dong Ke can actually make two questions? He is so strong?
　　 The report is still going on. The classmates in Lu Li's row all answered, "I can't do it, I found the answer online."
　　 When it was Lu Li's turn, Lu Li stood up and replied, "I couldn't do it at first. After I got the answer, I studied it, and then I used my own method to do three questions."
"me too."
　　 After Lu Li finished speaking, UU Read www.uukanshu.com Liu Qin also stood up and answered.
　　 Hearing the answers from Lu Li and Liu Qin, the classroom was quiet.
　　 Those students who "find the answer online" were full of horror. We haven't even fully understood the answer yet, but you have developed a new method to solve the problem?
　　 Dong Ke also changed his expression, turned his head and glanced at the two of Lu Li, with an incredible horror in his eyes.
　　 Dong Ke had already done this test paper, and Yang Lin had also explained it to Dong Ke. This time, Dong Ke used his own problem-solving ideas to make two questions.
　　 Now, Lu Li and Liu Qin have used their own methods to make three questions?
　　 It was only a day after they got the test papers, and I was studying these topics a month ago! They are so strong?
　　 Teacher Yang Lin's shock was more serious than others.
　　 Given the difficulty of this set of test papers, it is normal that it cannot be done. Finding the answer online is also in the expectation of Teacher Yang Lin.
　　 Even if the answer is found online, it is not easy to read and understand the answer within a few hours during the day.
　　 Originally, Teacher Yang Lin expected Lu Li and Liu Qin to understand and understand the answer at most, this level.
　　 Now... they even said that they solved three problems with their own methods and new methods!
　　 There are only three questions in this set of test papers that can have other problem-solving ideas, and the remaining three questions have no other problem-solving methods. Lu Li and the others have reached the limit.
　　 Dong Ke did this set of test papers a month ago, and I explained it to him. Until now he can solve two problems in his own way. Lu Li and Liu Qin did three things.
　　 They are so strong?
　　 No wonder they dare to call themselves "geniuses" in front of me, it turns out they really have this strength!
