The last subject of mathematics.

Zhao Hua moved a small stool and sat next to Liu Chen, but his attitude was very relaxed, not as strict as before. Liu Chen said, "Teacher Zhao, why don't you check me for your electronic dog?"

Zhao Hua had known that the math questioner was Mr. Zheng, an old guy who was unable to die and was not worth his life. He smiled and said, "If you can find someone to cheat in this math test paper, it will be your ability."

Liu Chen didn't agree. How difficult could it be if he said so mysteriously?

After the test paper was sent, about 99% of the students' first reaction was dumbfounded. The first multiple-choice question was that they could not understand the question. The remaining one percent of the students could not understand any questions. The ignorant person was fearless and directly called a C to continue the answer below.

About half an hour later, more than half of the students in the first five exam rooms were as sad as my father who had just died, and his self-confidence became negative in an instant. He repeatedly asked himself, am I really not a bad student?

These questions are really brain-burning. Which one lacks the question given by a guy who is a great master?

One and a half hours later.

"Students, there is still half an hour left, please hurry up." Li Ping walked back and forth in the examination room to remind everyone.

Not only the fourth exam room, most students started to panic when they heard the countdown. The more they went forward, the more panic he became.

In the first exam room, there was even someone who had not yet done a big question. Even the previous multiple-choice and fill-in-the-blank questions could not guarantee that they would get 60. It turned out that they could easily exceed 120, but now it is difficult to pass the calculation once they calculate!

No matter how strong your mental quality is, you will be panicked immediately. The better your grades are, the more panicked you are.

Meng Qingqing, who was sitting in the front row of the first exam room, also frowned. What she did was not ideal. The solution to the first big question was not complicated, but the calculation was too large.

Analytical geometry and equations solve, make several auxiliary lines, and there are several circle equations involved, and your head will be lost. If you find that there is no answer in the end, what kind of collapse will it be?

Meng Qingqing's psychological quality has been calculated. Xiao Guoping, who was in the same row with her, obviously breathing has increased. The pen in his hand kept writing, and his thoughts have become confused.

After all, I am still a second-year high school student. I don’t practice enough exercises and have too proud personality. I am most easily hit. It was obviously another mistake in thinking and I actually smashed my pen on the desk and made a very heavy sound.

A genius girl cannot withstand the blow of math that is only 100 years old.

The only person who can remain calm in the first exam room is Tian Zhiguo, who is known as the little prince of mathematics.

Twenty minutes left!

Most students have not even made a big question, and their mood is extremely collapsed, their heartbeats are rapid, and they are extremely tormented every minute and every second. They can look at the time for more than ten seconds. I really wish I could open my mind at this moment and solve the questions I can't figure out.

However, reality is cruel. The more impatient you are, the more useless you are. The hands of those formulas are trembling.

The 24 most relaxed and leisurely people in the exam room are Liu Chen. It’s difficult, and this question is indeed very difficult!

But what is Liu Chen's math attainment? If he had listened to the persuasion of a well-known mathematics professor at Jianghai University, he would have been a well-known mathematician. In his opinion, this simple primary mathematical thinking is pediatrics.

It is no different from college students watching primary school mathematics application problems.

Sister Fan was safe and agreed to Teacher Gu. Liu Chen did not hand over the paper in advance, but closed his eyes and pondered. He closed the test paper and didn't move for almost half an hour.

Zhao Hua glanced at him and thought disdainfully: "Just pretend, as soon as the time comes, I will collect your test papers immediately."

...

"Students, there are still five minutes left to sort out the test papers and check for omissions. When the time comes, everyone sit in their seats and don't move. After collecting the test papers, they will leave." The invigilator reminded almost at the same time.

In the fourth exam room, Liu Chen was still closing his eyes to rest.

Seeing that he looked like he was so angry, Zhao Hua said proudly: "If you can't do it now, you can't do it. It's useless to struggle. Apart from multiple-choice questions, there is no big question that can be done in five minutes. It's better to give up and check the questions you have already done, and strive to get points."

The invigilators in other examination rooms were also puzzled, especially in the first three examination rooms, which have not submitted their papers in advance so far.

All the students were pondering, just like studying a wordless heavenly book, and they bit the pen in their hands, making a creaking sound.

After the teachers reminded the time, a female classmate with a slightly weaker psychological quality in the second exam room actually started to cry.

Since childhood, he has been a good child in the eyes of his parents, a good student in the eyes of his teachers, countless stunning arms, three good students, excellent class cadres and other honors since childhood, and has been admired and spoken by countless poor students.

It was such an extremely proud girl who could not bear the pressure of the upcoming exam time and started crying.

The first ten exam rooms were almost full of heavy breathing sounds of students' collapse, and there was also a smell of sweat. Which student was not sweating on his forehead, his eyes were hairy and his whole body was trembling. The exam was so bad.

Dangdang..., the ringtone for handing over the paper rang.

Zhao Hua was the first to rush over to collect Liu Chen's test paper. When he got it, he wanted to open it and take a look at the big questions behind it.

Liu Chen covered his hand and smiled and said, "Teacher Zhao, this is not very consistent, please seal it up."

Zhao Hua smiled. Now he knows that it’s embarrassing. OK, I won’t read it for now, and seal it up. The ugly daughter-in-law will meet her parents-in-law sooner or later. You will eventually review the test paper.

After a while of rest, Liu Chen stood up and walked out of the examination room. Many of the students had similar expressions, and cold sweat was flowing on their foreheads, and their expressions were as dumb as if they were dumbfounded.

Just after walking a few steps, I saw Du Ning walking out with her schoolbag on her back. When I saw Liu Chen, a smile appeared on her bitter face and said worriedly: "Boss, how are you answering? I originally thought I could get 110 this time, but now I'm afraid it's hard to get 80."

"This time the question is very difficult. If you can exceed 80, it will be quite good. I guess the average score of the whole grade this time is probably less than 60." Liu Chen patted his shoulder and comforted him with a smile.

"Really?" Du Ning was unbelievable, mainly because he almost didn't do the following big questions and couldn't fully feel the difficulty. He wrote most of the steps for the second big questions.

Liu Chen nodded.

"I'm going to die." A classmate just walked out of the examination room and screamed, then ran to the playground. His back looked a little lonely.

After the math test, the first sentence when the students met was basically "I'm dead, I want to kill the teacher who gave the test paper."

"When will I go, call me brother, I will also make up for it." Another student would roughly answer this.

Liu Chen and Du Ning walked forward together. When they passed the first examination room, someone rushed out and hit Liu Chen. A fragrant breeze drifted into their nostrils. The man pushed Liu Chen and stood up straight and ran away.

The flowing long hair shook for a moment. It turned out to be Xiao Guoping. After just one meeting, Liu Chen saw her eyes turn red. It must be because of the math exam that was hit. I think this test was indeed too difficult and the calculation volume was too large.

"You must be wrong!" A sharp male voice came from the first examination room.

The two looked inside. At this moment, Meng Qingqing and the little prince of mathematics Tian Zhiguo were arguing on the blackboard. What is the solution to the third-last question? None of the students in the first exam room did the finale, and the fastest progress was Tian Zhiguo.

This person taught himself a complete high school course in his first year of high school. It is said that he is now watching [Advanced Mathematics] in college. He often plays a guest role in math teachers to teach students, and his grades remain within the 20th grade.

"Although I don't quite understand the method you mentioned in this question, the results you gave through this method are definitely wrong. I used the method I learned in high school to calculate it step by step, and I can definitely be correct."

Meng Qingqing drew a stroke on the blackboard, and her long hair tied up, and her slender neck became more and more obvious, like a proud little swan dancing ballet.

Qian Shuai stood aside and was determined to help Meng Qingqing, saying, "Qingqing is right, you are not wrong, don't argue anymore."

Tian Zhiguo opened his eyes and shouted: "Shut up, you don't need to be muddy."

Qian Shuai blushed embarrassedly, and he quickly wrote a formula and said proudly: "This question is very complicated to do with [Elementary Mathematics], and the calculation amount is also very large. In the university textbook [Advanced Mathematics], there is a formula for finding the method of transformation limits called Luobida Law. If the numerator is the limit of type 00, you can find the derivation and then find the limit at the same time. The results are the same. The results will never be wrong with this method. Meng Qingqing, you must have done this question wrong."
