A genius? I just love studying.

Chapter 34 Submit papers in advance
[Your math level has increased from level 2 4% to 5%]

[Your insight level increased from 2.0 to 2.1]

After writing the last word, several comments suddenly popped up in front of Chen Hui.

My math level and insight have actually improved!
Chen Hui was overjoyed.

His math level was okay, but it was extremely difficult to improve his insight. Apart from the last time when Zhang Anguo deliberately made things difficult for him, he only knew that he could add points using free attributes.

I didn’t expect that after solving this number theory problem, I would improve again.

By this calculation, Zhang Anguo can be considered his lucky general.

Sure enough, in addition to hard work and diligence, occasional flashes of inspiration are equally important in learning mathematics.

No wonder geniuses like Gauss were able to come up with groundbreaking theories at a young age.

Restraining his joy, Chen Hui looked at the fourth question.

This question is a bit strange. Not only is the content of the test strange, but the title is also strange.

This is also a number theory problem!

Generally speaking, in this type of exam, there will only be one major question for one knowledge point.

Even if number theory is the brightest pearl in mathematics, it shouldn't be so special.

But this has nothing to do with Chen Hui. He just needs to solve this problem now.

[In a finite sequence of real numbers, if the sum of any 7 terms is negative and the sum of any 11 terms is positive, determine the maximum number of terms in this sequence.]

The question is very simple, of course, it means that the description of the question is very simple. Mathematics is like this. A question with a complex description must be very complex, and a question with a simple description must not be simple.

Chen Hui was quite depressed. He had a basic understanding of number theory but had not studied it in depth. He did not expect that this provincial competition would have two major number theory questions in a row for the first time.

He was prepared for a hard fight.

However, just as Chen Hui was about to start writing, an idea suddenly came to his mind.

Chen Hui could feel that after his insight was raised to level 2, he was already much sharper than his classmates, even those in the mathematics competition team. He probably had already reached a very high level. Although this time the improvement was only 0.1, it was still a great step forward and should not be underestimated.

call!
With a sigh of relief, Chen Hui put away his pen cap, packed up his stationery, ID card and admission ticket, and then raised his hand.

Motion sickness had a significant impact on him, causing his head to still feel dizzy, but fortunately he did not disappoint, as the questions this year were not difficult and he still managed to finish them.

Especially the flash of inspiration just now, which allowed me to solve the last problem perfectly in just a few minutes.

With full marks, I should be able to get first place in the province, right?
He was looking forward to when the bonus would be paid, but now he just wanted to find a place to eat something and have a good rest.

In order to keep a clear mind during the exam, they just had some bread for breakfast and didn't dare to eat more. After more than an hour of brain battle, he was now very hungry.

"?"

Li Bin, who had been paying attention to the two of them, noticed his actions at the first moment and walked over.

"No more checking?"

Looking at the filled test paper, Li Bin couldn't suppress the surprise in his eyes.

I subconsciously glanced at the clock hanging at the back of the classroom. The exam had only started for a little over an hour.

"no need."

Chen Hui shook his head.

There are always people who, after the exam, look at their test paper and feel that they were careless and made mistakes in some simple questions.

But in fact, as long as you are wrong, it means you don’t know how to do it. If you really know how to do it, it is impossible to be wrong.

Chen Hui has the confidence that he will not make mistakes in anything he knows, and he happens to know all the answers to this set of questions!
"Okay, leave the draft paper and the test paper, and you can go."

Li Bin didn't say much. There was no rule in the math competition that required students to hand in their papers half an hour in advance. Candidates could leave whenever they wanted.

The commotion here naturally attracted the attention of the entire classroom. After all, many people were still doing fill-in-the-blank questions, and Chen Hui, who handed in his paper at this time, naturally attracted attention.

"It's really hard for him to persist for another hour before handing in the paper early!"

Zeng Jian, Chen Hui's junior high school classmate, happened to be in this examination room. When he saw that the person who handed in the paper early was Chen Hui, he looked up, sneered in his heart, and then stopped paying attention to it. He continued to look at his own test paper and pondered.

Tan Junjie, struggling with the first major question, looked up and sighed. Although Chen Hui and he seemed to be competitors, they both represented No. 2 Middle School, and he still hoped Chen Hui would do well. He was also understandable. Chen Hui was only a freshman, after all, and had experienced some unexpected illness today, leaving him feeling unwell. It was normal for him to give up early.

Just think of it as experiencing the atmosphere in advance and accumulating experience for next year's exam.

Liang Peixuan subconsciously looked towards Chen Hui's position. He didn't think Chen Hui was someone who would give up easily, so, could it be that he had already finished it?

"Everyone should do their own thing. Don't whisper to each other or look around!"

The invigilator's voice rang out, instantly extinguishing the commotion in the classroom and turning it quiet again.

Liang Peixuan quickly withdrew his gaze, but ultimately failed to see Chen Hui's test paper.

After finishing the second big question, Deng Leyan, whose forehead was already sweating, looked up without much emotion in his heart.

Given the difficulty of this year's questions, no one can finish them in an hour.

This person handed in his paper early, obviously because the questions were too difficult and he gave up.

This is also normal. He just took a look at the third big question and also had no idea. He might not be able to solve it in the end. It is understandable that the man chose to give up.

He also remembered that some classmates had mentioned that person before. He seemed to be from No. 2 Middle School and his junior high school math score was only around 50 or 60 points.

It's ridiculous for such a person to participate in a math competition!

People who give up so easily are simply blaspheming mathematics.

He will never give up. To study mathematics, one should have the spirit of hard work!

……

Outside the classroom, An Chengzhang and Zhang Anguo did not wander around, nor did they go back to the classroom to rest. They had no mood to wander around, nor could they calm down to rest.

Both of them had more or less certain expectations for this exam, but motion sickness led to too many uncertainties.

The two of them stood outside the examination room, milling around like ants on a hot pan, feeling as if each day was a year.

Suddenly, An Chengzhang noticed a figure appear at the door of the examination room.

It’s Chen Hui!
A hint of joy appeared on An Chengzhang's face, but it quickly disappeared.

Looking at the time, the exam had only started for more than an hour. If Chen Hui came out at this time, he would most likely have handed in a blank paper.

"It doesn't matter. The important thing is to participate. We will be well prepared and come back next year."

An Chengzhang patted Chen Hui on the shoulder and comforted him, saying that motion sickness was indeed beyond their expectations and it was just their teacher's fault.

"Ok!"

Chen Hui nodded in agreement. It was so easy to get 5,000 yuan, he would definitely come again next year.

"Are you hungry? Let's go eat something."

An Chengzhang said this and took Chen Hui to the cafeteria of Rongcheng University.

At this time, Zhang Anguo also came up and asked with concern, "What do you think of this question?"

"It's okay, it's pretty simple."

Chen Hui answered truthfully.

This year's fill-in-the-blank questions were indeed very simple, and the big questions were a bit difficult, but they were not a problem at all.

The first question is about number series. You just need to understand the concept of norm, list a few special cases, find the pattern, construct the target formula, and prove it according to different situations.

The proof is rather complicated, but the idea is natural and not difficult. Chen Hui guessed that this should be an easy question.

The second question is a plane geometry proof question, which is to prove that four points are cocircular. It is also a conventional proof method. Draw auxiliary lines and use the diagonal angle and proportion to find the complementary angles. It can also be proved. It is indeed a bit complicated, but not difficult.

The third question was about number theory. For an ordinary high school student who had never studied number theory, this question would most likely be impossible to solve. Fortunately, he had learned some number theory and happened to know Euler's theorem, so he was lucky.

The last question was quite interesting. If Chen Hui hadn't had a sudden inspiration and thought of a clever solution, he didn't think he would be able to hand in the paper so quickly.

"That's good, that's good, let's go eat."

An Chengzhang stopped Zhang Anguo who was about to continue asking questions. He said that he came out so early and the situation was special, so he didn't want to blame the kid. Let's fight again next year.
