Chapter 162 Submitting the Papers Early Again

Mathematics has always been the most difficult subject for students. In other words, it is a subject that is particularly troublesome to 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 people. All kinds of application questions that I want to hang myself.

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

But now, when the math papers have just been handed out, Lin Feng glanced over them, and immediately found similar question types and solutions in his head, and some even included some Mathematical Olympiad questions, which Lin Feng has been reviewing quickly in the past two days When I remembered, I ate everything in my stomach.

"Ah! There are 50 or 60 points in the paper of 150 points, and many of them are Mathematical Olympiad questions. Moreover, even the other questions are not free points. A trap, you need to be careful to avoid mistakes. The difficulty of the math paper this time is really not low!"

It took two minutes to scan the ten-page math paper from beginning to end, and Lin Feng couldn't help sighing in his heart. And the other examinees couldn't help crying, their hands holding the papers couldn't help shaking.

Not only the third examination room where Lin Feng was located, but also the other examination rooms. Almost all the examinees were frowning and looking at the test papers, and they were cordially greeting the 18 generations of the immediate family members of the teacher who produced the test papers. up.

"Olympiad questions? All kinds of trap questions... including the Chinese test paper that was so difficult in the morning. It seems that this time the school deliberately wants to increase the difficulty, and it is a wake-up call for us before the college entrance examination!"

Qin Yanran, who got the paper, couldn't help expressing such emotions when her eyes swollen from crying scanned the questions on the paper. However, although these problems are somewhat difficult and troublesome for her, 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 rustling sound that had appeared during the Chinese test in the morning sounded again.

rustle...

It was the sound of the pen nib writing rapidly on the paper. In the silent classroom at this time, other candidates hadn't written yet, but Lin Feng was writing quickly, which immediately attracted everyone's attention. come over.

"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 working on the next big question! Could it be that he has finished all the multiple choice questions in front of him? This is impossible! It's only been five minutes since the exam started, so it must be scribbling. If he can do such a difficult paper so quickly and correctly, it will be against the sky! "

...

Qin Yanran and other examinees had the same doubts. The first questions in the math paper were all multiple-choice questions and fill-in-the-blank questions. The big questions that required a lot of formula derivation and disintegration steps were at the back. Obviously doing the big question later.

When most people answer questions, they start from the beginning, first do the small questions in front, and then do the big questions later. If it is said that Lin Feng is doing big questions right now, Qin Yanran guessed that it is very likely that Lin Feng wrote the answers for the multiple choice questions and fill-in-the-blank questions randomly, and even the steps for the big questions later were also scribbled. .

"This Lin Feng is giving up on himself again! He wrote the answers indiscriminately! If only he had read the notebook I gave him just now! In the first few pages, he memorized the solutions to the same type of questions on several papers... ..."

Now Qin Yanran was angry and helpless towards Lin Feng, her face was blushing, she could only hold a pen, empty out all other thoughts, and concentrate on doing the paper.

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

But at this time, Lin Feng only had 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 mathematical problem, you will automatically recall the knowledge points and formulas involved in the problem in your mind, and you can even fully understand the mind and purpose of the person who made the problem. Mastery of mathematical knowledge points or formulas and theorems.

At this time, Lin Feng enjoyed this problem-solving process very much. This kind of happiness is also indescribable. When doing the previous multiple-choice questions, Lin Feng didn't need to calculate on the draft paper at all. As soon as he finished reading the questions, he quickly completed the calculation and substitution verification in his mind. The correct answer was selected from the alternative answers.

The same is true for filling in the blanks. As long as Lin Feng reads the questions, finds the knowledge points and theorems and formulas to be investigated, and then quickly calculates according to the method, the answer is naturally ready to come out.

Answering questions and application questions, as well as combining functions, geometry and equations, is cumbersome and labor-intensive, plus some calculation traps deliberately set by the question maker. Lin Feng had to carefully check and calculate many times before he could Feel free to write down the steps to solve the problem accurately.

Examining questions, thinking, calculating, answering questions, writing out the steps to solve the questions...

Lin Feng wrote a beautiful word "solution" under the title of the paper very chicly, and then scribbled down the correct step-by-step process of solving the problem line by line. The sense of accomplishment and happiness is what every student feels when he is doing the test paper. all yearn for.

When Lin Feng scribbled and wrote the last character on the last comprehensive application question of the Olympiad difficulty level, he put the pen on the table with a snap, and flipped through a total of ten pages of papers. Seeing these perfect answer papers, his forehead But there are already bean-sized sweat drops falling down.

"If there is no accident, my math paper is a perfect score of 150. Huh... So it turns out that solving math problems is really rewarding. It is very rewarding to calculate the exact answers to those difficult problems. This feeling is really cool!"

Lin Feng, who was eager to do the paper again, smiled secretly, wiped the sweat from his forehead, looked around, and found that the other candidates were still racing against time to answer the questions, so he gently moved towards the teacher who was sitting on the podium. The invigilator slightly raised his hand and said in a low voice, "Teacher! I want to hand in the paper!"
