Chapter 162: Submit papers in advance again

Mathematics has always been the most troublesome subject for students. In other words, it is a subject that is particularly troublesome for students all over the world. Although 1234567890 is just a simple number, the combination of these numbers and some seemingly simple formulas and theorems, as well as many practical problems, will produce countless amazing Just want to hang a variety of word problems.

Permutations and combinations, trigonometric functions, geometric applications, and various equations and functions. God knows why there is such a life-seeking subject as mathematics in the world. In the past, Lin Feng had a headache when he saw numbers and application problems, and he was dizzy when he saw those function symbols and various geometric figures.

But now, when the math papers were just issued, Lin Feng glanced over, and immediately found similar question types and problem-solving methods in his head, and some even some Mathematical questions. Lin Feng has been quickly reviewing these two days. When I remembered, I ate everything in my stomach.

"Ah! One hundred and fifty-point papers, there are actually fifty-sixty-point problems, many of which are also Olympiad questions. Moreover, even for other questions, they are not divided questions. Basically, the people who wrote the papers set up answers. Trap, you need to be careful to avoid mistakes. This time the difficulty of the math papers is really not low!"

It took two minutes to scan a total of ten pages of math papers from beginning to end, and Lin Feng couldn't help but sigh in his heart. The other candidates couldn't help crying, and their hands with the paper couldn't help shaking.

Not only the third examination room where Lin Feng was located, but the situation in other examination rooms was the same. Almost all the candidates were looking at the papers with frowning, and they warmly greeted the teacher’s 18th-generation direct family members. Up.

"Mathematics for Olympiad? All kinds of traps...including the difficult Chinese test paper in the morning. It seems that this time the school is deliberately trying to increase the difficulty and give us a warning before the college entrance examination!

Qin Yanran, who got the paper, couldn't help expressing such emotions when she swept across the question with her swollen eyes. However, these problems are somewhat difficult and troublesome for her, but as long as she is careful and serious, there is no problem.

And when Qin Yanran had just finished reviewing the questions and was about to start with the first multiple-choice questions, the rustle that appeared during the Chinese exam in the morning rang again.

Rustle...

It was the sound made by the tip of the pen writing quickly on the paper. In the silent classroom at this time, the other examinees hadn't started writing yet, but Lin Feng was writing fast, and immediately attracted everyone’s attention. come.

"It's him again? This Lin Feng, even writes math papers so fast? I guess he's scribbling again!"

"The previous ones are multiple-choice questions and fill-in-the-blank questions. With Lin Feng's current answering speed, he should be doing the next big question! Could it be said that he has finished all the multiple-choice questions before? This is impossible! This is just the beginning The five-minute test must be scribbling, such a difficult paper, if he can do it so quickly and correctly, it will be against the sky!"

...

Qin Yanran and other examinees have the same doubts. The questions in the front of the math paper are multiple-choice questions and fill-in-the-blank questions. The big questions that require a large number of formula derivation process disintegration steps are behind. Lin Feng is now writing big questions quickly in sand. Obviously, I am doing the next big topic.

When most people answer questions, they start from the beginning, first doing the small questions in front, and then the big questions in the back. If Lin Feng is doing a big question now, Qin Yanran guesses that it is very likely that Lin Feng's multiple-choice questions and fill-in-the-blank questions in front of it were all random and wrote an answer, and even the steps behind the big question were written in random. .

"This Lin Feng is arrogant and abandoning himself again! He wrote the answers indiscriminately! It would be great if he had just read the notebook I gave him! Just go to the front page and memorize the same type of problem solving methods on several papers... …"

Now Qin Yanran is angry and helpless towards Lin Feng, blushing, she can only hold a pen, empty her other thoughts, and concentrate on writing the paper.

Soon, half an hour passed for the exam. Some students in the examination room only finished the multiple-choice questions. The better fill-in-the-blank questions were half done and half empty. Even the most powerful Qin Yanran started to do the answer questions at this time.

But at this time, Lin Feng had only two big questions left on the last page. What is the fun of solving problems? What is the fun of solving math problems? That is, when you see this math problem, your mind will automatically recall the knowledge points and formulas involved in the problem, and you can even fully understand the mind and purpose of the person who asked the question. What you want to investigate is which of the candidates Mastery of mathematical knowledge points or formula theorems.

At this time, Lin Feng enjoyed this kind of problem-solving process. This kind of happiness is also indescribable. When doing the previous multiple-choice questions, Lin Feng did not need to calculate on the draft paper. Just after reading the questions, he quickly completed the calculations and substitution verifications in his mind. The correct answer was selected among the alternative answers.

The same is true for fill-in-the-blank questions. As long as Lin Feng has read the questions and found the knowledge points and theorems to be investigated, and then quickly calculates according to the method, the answer is naturally ready.

It is the answering questions and application questions, as well as the combination of functions, geometry and equations. The answering questions are more tedious and time-consuming, plus some calculation traps deliberately set by the author~www.wuxiaspot.com~ Lin Feng must be careful to go through After checking the calculations many times, I was relieved to write down the steps to solve the problem accurately.

Review questions, think, calculate, answer questions, write out the steps to solve the problem...

Lin Feng smartly wrote a beautiful "solution" under the title of the paper, and then transcripted the correct problem-solving steps line by line. The sense of accomplishment and happiness is that every student is doing the test paper. All desire to obtain.

When Lin Feng rushed to write a book, wrote the last character on the last comprehensive application problem of Mathematical difficulty level, slapped the pen on the table, turned a total of ten pages, and saw these perfect answer sheets, forehead But the sweat is already falling down.

"If there is no accident, my math paper is a perfect score of one hundred and fifty. Huh... It turns out that solving math problems is really a sense of accomplishment. I can calculate accurate answers to those problems. This feeling is so cool!"

Lin Feng, who wished to do the papers again, smiled to himself, wiped the sweat from his forehead, looked around, and found that the other candidates were still rushing to answer the questions, so he gently moved toward the podium. The invigilator of the exam raised his hand slightly and whispered: "Teacher! I want to hand in the paper!"
