Mathematics has always been the most troublesome subject for students. In other words, it is a particularly troublesome subject for students all over the world. Although 14567890 is just a simple number, these numbers and some seemingly simple formulas and theorems, there are many practical

When the questions are combined, there will be countless application problems that make people want to hang themselves just by looking at them.

Permutations and combinations, trigonometric functions, geometric applications, and various equations and functions. God knows why there is such a boring subject as mathematics in the world. In the past, Lin Feng also got a headache when he saw numbers and word problems.

Damn, my head feels dizzy when I see those function symbols and various geometric figures.

But now, when the mathematics paper was just handed out, Lin Feng glanced at it and immediately searched for similar question types and solution methods in his mind, some even some Mathematical Olympiad questions, which Lin Feng quickly reviewed in the past two days.

When I was remembering, it was all eaten into my stomach.

"Yeah! The 150-point paper actually has 50-60 points of difficult questions, many of which are Mathematical Olympiad questions. Moreover, even other questions are not given points. Basically, the examiner has set the answer

Traps, you need to be very careful to avoid making mistakes. The difficulty of this math paper is really not low!"

After spending two minutes scanning the ten-page mathematics paper from beginning to end, Lin Feng couldn't help but sigh in his heart. The other candidates were even more on the point of crying, and their hands holding the paper couldn't hold it back.

He started to tremble.

Not only the third examination room where Lin Feng was located, but also the situation in other examination rooms was the same. Almost all the candidates were looking at the papers with frowns at this time, and in their hearts they were cordially greeting the eighteenth generation immediate family members of the teacher who wrote the papers.

.

"Math Olympiad questions? All kinds of trap questions... including the very difficult Chinese language test paper in the morning. It seems that the school deliberately wants to make it more difficult this time, giving us a wake-up call before the college entrance examination!"

Qin Yanran, who got the paper, couldn't help but sigh when her eyes were swollen from crying and she glanced at the questions on the paper. However, although these problems are a bit difficult and troublesome for her, as long as she is careful and serious

, and there is no problem.

And when Qin Yanran had just finished reviewing the questions and was about to start from the first multiple-choice questions, the rustling sound that had appeared during the Chinese language test in the morning rang again.

swish swish...

It was the sound made by the pen tip writing rapidly on the paper. In the silent classroom at this time, other candidates had not yet started writing, but Lin Feng was writing very fast, which immediately attracted everyone's attention.

come over.

"Is it him again? This Lin Feng can even write math papers so fast? He is probably writing randomly again!"

"The previous ones are all multiple-choice questions and fill-in-the-blank questions. With Lin Feng's current answer speed, he should be doing the big questions at the end! Could it be said that he has finished all the multiple-choice questions in the past? This is impossible! This is just the beginning.

The five-minute exam must have been scribbling. It would be incredible if he could do such a difficult paper so quickly and correctly!"

…

Qin Yanran and other candidates had the same doubts. The questions at the front of the mathematics paper were all multiple-choice questions and fill-in-the-blank questions. The big questions that required a lot of formula derivation and disassembly steps were at the back. Lin Feng was writing the big questions quickly in a rustling way.

Obviously he is working on the big question at the end.

When most people answer questions, they start from the beginning, first doing the small questions in the front, and then the big questions in the back. If Lin Feng is doing the big questions now, Qin Yanran guessed that Lin Feng is most likely to do the previous multiple-choice questions and the big questions.

The answers to the fill-in-the-blank questions were written randomly, and even the steps for the big questions at the end were also written randomly.

"This Lin Feng is giving up on himself again! He's writing random answers! It would be great if he just read the notebook I gave him! On the first few pages, he wrote down several solutions to the same type of questions on the paper...

…”

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

Soon, half an hour had passed for the exam. Some students in the exam room had just finished answering the multiple-choice questions. Half of the better fill-in-the-blank questions were completed and half were left blank. Even the most powerful Qin Yanran had just started at this time.

Do answer questions.

But at this time, Lin Feng only had two big questions on the last page left. What is the fun of solving problems? What is the fun of solving math problems? That is when you see this math problem

, the mind will automatically recall the knowledge points and formulas involved in the question, and can even fully understand the mind and purpose of the person who asked the question. What is to be tested is which mathematical knowledge point or formula theorem the candidate has mastered.

At this time, Lin Feng enjoyed the process of solving problems. This kind of happiness was also indescribable. When doing the previous multiple-choice questions, Lin Feng did not need to calculate on the draft paper at all. Just after reading the questions, his mind

The calculation and substitution verification were completed very quickly, and the correct answer was selected from four alternative answers in an instant.

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

Answering questions and application questions, as well as questions that combine functions, geometry, and equations are more cumbersome and time-consuming. In addition, some calculation traps deliberately set by some question makers, Lin Feng must carefully go through many calculations before he can solve the problem.

Rest assured that the steps to solve the problem are written down accurately.

Review the questions, think, calculate, answer the questions, write down the steps to solve the problems...

Lin Feng very coolly wrote a beautiful word "solution" under the question of the paper, and then transcribed the correct step-by-step process of solving the problem line by line. That sense of accomplishment and happiness is what every student feels when doing the test paper.

All desire to obtain.

When Lin Feng wrote quickly, he wrote the last character on the last comprehensive word question of Mathematical Olympiad difficulty level. He put the pen on the table and flipped through a total of ten pages of papers. When he saw these perfect answers, his forehead was filled with tears.

But big drops of sweat were already falling down from the top.

"If nothing else, my math paper got a perfect score of 150 points. Huh... It turns out that solving math problems is really a sense of accomplishment. Calculating accurate answers to difficult problems, this

It’s such a great feeling!”

Lin Feng, who couldn't wait to take the paper again, smiled to himself, 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 walked towards the podium where he was sitting
Chapter completed!
