Mathematics has always been the most troublesome subject for students. Pen Fun Pavilion wWw. ｂiquge。 In other words, it is a particularly troublesome subject for students all over the world, 1234567890 although it is just simple numbers, these numbers are combined with some seemingly simple formulas and theorems, as well as many practical problems, and there are countless practical problems that make people want to hang themselves.

Permutations and combinations, trigonometric functions, geometric applications, and a wide variety of equations and functions. God knows why there is such a ****** subject as mathematics in the world, in the past, Lin Feng also had a headache when he saw numbers and application problems, and his head was dizzy when he saw those function symbols and various geometric figures.

But now, when the math paper was just sent, Lin Feng swept it over, and immediately searched for similar question types and solution methods in his head, and some even some Olympiad problems, these Lin Feng quickly reviewed his memory in the past two days, but they all ate it into his stomach.

"Ah, there are 50 or 60 difficult problems in the 150-point paper, and many of them are Olympiad math problems. Moreover, even the other questions are not sent to the questions, and basically the person who produces the paper has set a trap for answering the questions, so you need to be especially careful to avoid mistakes. This time, the difficulty of the math paper is really not low!"

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

Not only the third examination room where Lin Feng is located, but the situation in other examination rooms is also the same, almost all the candidates are frowning at this time and looking at the papers, and they are cordially greeting the eighteenth generation of the immediate family members of the teacher who came out of the papers.

"Olympiad problems?all kinds of trap problems...... Including the Chinese test paper that is so difficult in the morning, it seems that this time the school deliberately wants to increase the difficulty and sound a wake-up call before the college entrance examination!"

Qin Yanran, who got the scroll, couldn't help but sigh when her crying swollen eyes swept over the title on the scroll. However, although these problems are 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 appeared during the Chinese exam in the morning sounded again.

Rustle rustle......

It was the sound of the tip of the pen writing quickly on the paper, and in the classroom at this time, the other candidates had not yet started writing, but Lin Feng was writing quickly, which immediately attracted everyone's attention.

"It's him again? This Lin Feng, even the math paper is written so fast? I guess he's scribbling again!"

"The front ones are all multiple-choice questions and fill-in-the-blank questions, with Lin Feng's current answering speed, he should be doing the big questions in the back! Could it be that he has finished all the multiple-choice questions in front of him? This is impossible! This is only five minutes after the exam, it must be scribbled, such a difficult paper, if he can still do it so quickly and correctly, it will be against the sky!"

……

Qin Yanran and other candidates have the same doubts, the questions in the front of the math paper are all multiple-choice questions and fill-in-the-blank questions, and the big questions that require a lot of formula derivation process disintegration steps are all behind, Lin Feng is now writing the big questions quickly in a rustling manner, and he is obviously doing the big questions in the back.

When most people answer questions, they start from the beginning, first do the first small questions, and then do the later big questions. If Lin Feng is doing a big question now, Qin Yanran guessed that Lin Feng is very likely to write an answer to the multiple choice questions and fill-in-the-blank questions in front of him, and even the steps of the big questions in the back are also scribbled.

"This Lin Feng is giving up on himself again! Writing answers randomly! How nice it would be if he had just read the notebook I gave him! On the first few pages, he memorized the same type of problem solving method on several papers......

Now Qin Yanran was angry and a little helpless with Lin Feng, her face was crimson, she could only hold the pen, empty all her other thoughts, and concentrate on making the scroll.

Soon, half an hour had passed for the exam. Some of the students in the examination room had only finished the multiple-choice questions, and the better fill-in-the-blank questions were half done, and half of them were empty, even the most powerful Qin Yanran only started to answer the 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 a problem? What is the fun of solving a mathematical problem? 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 questioner.

At this time, Lin Feng enjoyed this process of solving the problem 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 scratch paper at all, just after reading the question, he quickly completed the calculation and substitution verification in his mind, and instantly selected the correct answer from the four alternative answers.

The same is true for fill-in-the-blank questions, as long as Lin Feng finishes the question, finds the knowledge points and theorem formulas investigated, and then quickly calculates according to the method, the answer will naturally come out.

It is the solution questions and application questions, as well as the combination of functions, geometry and equations, which are more cumbersome and labor-intensive, plus some calculation traps deliberately set by the questioner, Lin Feng must carefully go through many calculations before he can rest assured that the accurate solution steps are written.

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

Lin Feng wrote a beautiful word "solution" under the title of the paper very chicly, and then transcribed the correct steps of solving the problem line by line, the sense of achievement and happiness is what every student is eager to obtain when doing the test paper.

When Lin Feng wrote hard, wrote down the last character on the comprehensive application problem of the last Olympiad difficulty level, put the pen on the table with a snap, and flipped through a total of ten pages, seeing these perfect answer sheets, the sweat droplets on his forehead were already the size of beans and soybeans.

"If nothing else, I got a perfect score of 150 points on this math paper. Call...... It turns out that solving math problems is really fulfilling, and it is really cool to calculate an accurate answer to that difficult problem!"

Lin Feng, who was eager to do the paper again, smiled secretly, wiped the sweat on his forehead, looked around, and found that the other candidates were still in full swing to answer the questions, so he gently raised his hand slightly to the invigilator sitting on the podium, and whispered: "Teacher!
