Du Wenxing said this to Ye Fei, obviously to ridicule Ye Fei, but what he said was very unskilled. He actually fired a map gun and almost insulted the entire class into low IQ.
However, this is also Du Wenxing's inadvertent loss, he knew this question is difficult, but unexpectedly, it is estimated that only one person in the class will do it.
Xueba doesn't understand Xueba's heart, Xueba also doesn't understand Xueba's heart.
Du Wenxing's words suddenly caused frying pans around.
The classmate originally aimed at Ye Fei's muzzle, but now some of them started to aim at Du Wenxing, but no one spoke.
Because they do n’t have the capital to quarrel with Du Wenxing, they ca n’t do anything in society, but the school is the place to learn, and learning is better than having a say.
Although the other classmates didn't speak, Qin Xiaomeng was already unhappy, saying: "Is it remarkable that you can make this question? Have the ability to solve the second question!"
Although Qin Xiaomeng can't do the second question, her score is not bad. It can be seen that the second question is much more difficult than the first question.
Although Du Wenxing made the first question, but as long as the second question could not be done, then he would not be eligible to receive additional credits from Professor Nie.
"Sorry, I'm doing the first question first, but listening to Qin Xiaomeng's meaning, you seem to be doing the second question first. Do you already have any clues? Tell me to share with you!" Du Wenxing smiled coldly. Although he likes Qin Xiaomeng, he believes that the best way to pursue a girl is not to chase, but to perform better than her and let the girl adore herself.
When other students heard it, they also wanted Qin Xiaomeng to suppress Du Wenxing's arrogance and said:
"Yes, Qin Xiaomeng, if you say that, you must have started the second question."
"Let Qin Xiaomeng tell us the second question!"
A group of students was noisy and clamoring aside.
Professor Nie smiled, looking at Qin Xiaomeng, and said: "Since everyone has said so, Qin Xiaomeng, do you have any ideas for solving this problem? It doesn't matter, what I thought of, boldly say it. This question is quite difficult. It doesn't matter if you can't do it. The important thing is to solve the problem. "
Professor Nie knows that Qin Xiaomeng ’s learning is good, and he has a flexible mind and a strong acceptance ability. Although this question may not be able to be made, there are still no problems when it comes to solving the problem.
Qin Xiaomeng was suddenly red-faced. If it is normal, she is certainly okay, but today Ye Fei is sitting next to her, and she is on a small class. She has not heard what Professor Nie said.
Professor Nie asked, Qin Xiaomeng couldn't say anything. Wasn't it embarrassing to go to grandma's house?
Qin Xiaomeng stood up, looked at the topic on the blackboard, and held the Buddha's feet temporarily, wanting to say something, but his lips opened, but he didn't know what to say.
There was silence in the classroom.
All students looked at Qin Xiaomeng.
Most of them saw Qin Xiaomeng's embarrassment and knew she couldn't do it either. Several girls who were jealous of Qin Xiaomeng snickered and whispered: "Aren't you a school bully? Is there today?"
Professor Nie held his glasses, and a deep disappointment appeared on his face. He was about to wave Qin Xiaomeng to sit down.
At the moment, Qin Xiaomeng felt that her cheeks were hot, and the blood seemed to be turned into magma. The small face was red and throbbing, almost bleeding, embarrassingly terrible. , Death never comes out.
At this time, Ye Fei handed over a piece of paper with a number written on it.
This number is 104.17, the number is very strange, because the exercises in the class are generally integers, rarely with a decimal point, not to mention there are two digits after the decimal point.
However, Qin Xiaomeng is now ignorant, and her brain is blank. Although she does not know what Ye Fei means, she still read the number subconsciously: "104.17."
Qin Xiaomeng read very arrogantly and his voice was very low, similar to that of mosquitoes.
However, the classroom that was originally quiet is now even quieter.
Soon a group of students laughed out loud.
"Miss Qin, how do you figure out such a precise number!"
A girl covered her mouth with her finger and said with a smile.
"Since elementary school, after so many years of mathematics, why can't I understand the rules of the teacher's questions. Although these questions are difficult, the answers are often very simple, generally within ten, how can it be a complicated number?"
"Yeah, with a decimal point, how did you calculate this answer! It won't be calculated with the calculator on the phone!"
Everyone laughed again and again, although it was different from the plan, but it was also a very happy thing to be able to laugh at Qin Xiaomeng's academic bully, but no one noticed that Professor Nie in front of the blackboard had a fixed expression.
"Professor Nie, I think the answer to this question is 14."
Du Wenxing said, he has been burying his head in this question just now, and now he has a rough result.
This result is far from what Qin Xiaomeng said.
Professor Nie recovered, and after looking at Du Wenxing, he scratched his head and said, "You can still get at least half of the score for the number 14."
Du Wenxing's complacent face, such a problem, at least half an hour to complete, he took a few minutes to get half the score, it is already very difficult.
"Professor Nie, what is half the score?" A boy shook his head, not quite understanding.
"Because the answer to 14 is wrong, the real answer to this question should be 104."
Professor Nie glanced at Qin Xiaomeng and said: "Mathematics is a rigorous subject, even if it is almost a mistake, it is all wrong, so 14 is half right, and if it is an exam, it will not get any score . "
At this point, Professor Nie paused before continuing: "This question is difficult. In the exam, half of them are additional questions. If you make the answer of 104, you can get all the scores, but ... If you get 104.2, you can get more additional points. "
In the classroom, all the students were shocked. The answer given by 104.2 and Qin Xiaomeng was too close!
When everyone looked at Qin Xiaomeng's gaze, it was no longer a sneer and mockery, but full of shock. In just a few minutes, she actually figured out such a problem? It is really amazing!
However, Professor Nie paused and said: "But in fact, the real answer to this question is 104.17. However, the result can be calculated either by a genius in mathematics or a graduate student in the mathematics department. Even so, it requires a lot of calculation, and even using a calculation tool will take several hours. "
As soon as this statement came out, the audience was shocked!
Professor Nie is very good and seems to be lenient to others, but in academics, he is famous for his rigor. This may be a common problem for mathematicians. There is absolutely no ambiguity in what he usually said. As much as he said, it must be, and there will be no exaggeration.
Now he said that the answer of 104.17 had to be done by math geniuses or graduate students in the mathematics department in a few hours.
But how did Qin Xiaomeng get this answer in such a short time?
