Teacher Dai pushed his glasses and began to smile proudly, Liu Aomei had no hope for Jiang Yan, so she was not much disappointed except for shaking her head, but Chen Xiaofa was a little anxious and wanted to solve some problems for his cousin, but when he saw the mathematical formulas, he was dizzy.

But Liu Aofeng became impatient and shouted: "Tubaozi, will you solve it, and if you can't solve it, you will admit defeat." ”

"Of course it will. After speaking, Jiang Yan picked up the pen and began to solve the problem.

The tip of the pen touched the manuscript paper with a slight sound, and after ten minutes, Jiang Yan stood up and handed the answer sheet to Teacher Dai: "I have solved it, five questions, there should be one question right." ”

Jiang Yan reviewed the problem in the first five minutes and solved the problem in the last ten minutes, which took about 15 minutes in total, which was so fast that Mr. Dai was a little unbelievable.

When he took the answer sheet and looked at the answer, Mr. Dai was even more surprised.

In fact, in Mr. Dai's opinion, since this Jiang Yan gave up halfway to study and came out to work, he must not be able to study, and he can be tested in a casual test. However, in order to be sure, he still spent ten minutes coming up with five questions that he thought were the most difficult.

How do you know that people have solved these problems in fifteen minutes, and they are all right.

"Hey, four-eyed field chicken, is this dirt bun right?" Liu Aofeng saw that Teacher Dai looked stupid, and shouted impatiently.

"All five questions are correct. Teacher Dai nodded helplessly.

As soon as these words came out, Chen Xiaofa was both happy and surprised. Liu Aomei looked unconvinced, could it be that these five questions are too easy? Quickly show those five questions to Liu Aofeng: "Xiaofeng, do you think you can do these five questions?"

"Sister, are you deliberately embarrassing me? Your brother and I are good at picking up girls, what is the way to solve the problem? And these questions are super difficult at a glance!" Liu Aofeng rolled his eyes. The formulas of these five questions are complicated, Liu Aofeng trembled when he looked at it, how could he solve them.

Next, it's time for Jiang Yan to come up with the question.

"Tu Baozi, I didn't expect you to really have two hits!" Before the question came out, Liu Aofeng praised Jiang Yan rarely, and gave Jiang Yan a thumbs up: "By the way, if your question can stump the four-eyed field chicken, I, Liu Aofeng, will obey you." ”

Jiang Yan smiled at Liu Aofeng, then picked up the pen and began to write questions on the manuscript paper.

In just a few minutes, Jiang Yan came up with a question, and then handed the manuscript paper to Teacher Dai.

After Mr. Dai took the manuscript paper, he was stunned, and everyone else was also stunned. Because there is only one question on Jiang Yan's manuscript paper.

Because the time of the competition is limited, only half an hour, each person can come up with five questions, and the more questions you have, the more time you will have to solve them. And Jiang Yan only came up with one question, and it was obvious that he suffered a lot.

"Jiang Yan, why do you only have one question? "The truth that if you have fewer questions, you will suffer a loss, even Chen Xiaofa can see it.

"This classmate Jiang, are you really only planning to come up with one question?" Teacher Dai stared at Jiang Yan a little angrily, after all, he had just made five questions, and Jiang Yan only came out with one, feeling that he was despised by Jiang Yan.

"Yes, there is only one, and if you solve this problem in half an hour, you will win. Jiang Yan smiled slightly, but his smile was full of confidence.

In fact, when Mr. Dai said that he wanted to solve the question, Jiang Yan had already made up his mind and only asked one question, and the difficulty of this question was naturally very high, and it rarely appeared in ordinary mathematics education or when doing problems.

Jiang Yan has solved countless problems, and the most difficult question he has encountered so far is the question of the sea topic in Minghua High School last time. The topic of the sea was chosen by Mr. Chen, who was born in Huaqing, and he was asked by a professor in the Huaqing period before him, and the difficulty can be imagined.

At that time, no second student in the entire Minghua High School could solve it except for himself, and among the teachers, except for the famous scholar Chen in the Huaqing Dynasty, there was no second teacher who could solve it. It is said that it took several hours for Mr. Chen to solve this problem.

And this question only appeared in Minghua and Mingli's two high schools, and I believe it has not been circulated, and this is in Jinghua City, I believe that this teacher Dai has never encountered this question before.

What's more, Jiang Yan also bought an "insurance", with his current mathematical ability, not to mention that he is already above Teacher Chen, at least he is also the same as him, so for this problem, he also made some changes and added some of his own ideas, which added some difficulty to this problem.

If the previous problem is regarded as an A+ problem, then the question after Jiang Yan's change is an A++ question, and now this changed question is solved by Mr. Chen himself, even if it is estimated that it will take half a day to solve it, Jiang Yan does not believe that the copper-smelling Teacher Dai in front of him will be more powerful than Teacher Chen.

Therefore, Jiang Yan is full of confidence in this question.

Teacher Dai snorted coldly after taking the question, in fact, Jiang Yan has already solved his own problem, if he solves Jiang Yan's question, at most it will be a draw. But Jiang Yan actually said that even if he won if he solved this problem, he obviously looked down on himself.

Teacher Dai smiled contemptuously, he really didn't believe that a student who dropped out of school and worked hard could find it difficult for him.

However, when he examined the question and planned to solve the problem, he found that this question does not seem to be complicated, but it is very difficult, and the answer to this question has too many possibilities, and if he solves it wrong in one step, he will deviate from the topic.

Gradually, the contemptuous smile disappeared from his face, replaced by a solemn face.

Fifteen minutes passed, and Mr. Dai didn't even write a word.

After another five minutes, Mr. Dai's hand holding the pen began to tremble, and beads of sweat were oozing from his forehead.

Liu Aomei and Chen Xiaofa were really curious, Jiang Yan's question was really so problematic, and Teacher Dai couldn't write a word in 20 minutes.

The two of them glanced at Jiang Yan and then at the question, but unfortunately, they had already passed the student years, and they couldn't see the reason for this question at all.

"Hey, four-eyed field chicken, can you solve it, if you can't solve it, admit defeat as soon as possible, don't be ashamed!" Liu Aofeng gloated, a scumbag like him doesn't have any good feelings for these teachers, and it has always been one of their pleasures to let teachers look foreign.

"I, I'm -----" Mr. Dai stammered speechless, and at the same time felt that he couldn't solve the problem.

Time passed minute by minute, and Mr. Dai still didn't write a word.

"Nine, eight, seven, six-----" and Liu Aofeng began to count down: "Three, two, one, stop!"

"Four-eyed field chicken, you lost!" Liu Aofeng laughed.
