Chapter 17 Advanced Mission Completed

Just like the college entrance examination, the first session in the morning of No. 3 Middle School also tests Chinese language.

Although Xu Yun has not reviewed Chinese these days, as it was his previous best subject, after quickly immersing himself in it under the influence of concentration, he could answer the questions quite fluently.

In addition, he also has good calligraphy, and he can get a lot of points just for writing.

It took about two hours to finish.

But since the school did not allow formal examination papers to be submitted in advance, he could only read the papers back and forth in boredom.

But there is no intention to check.

Chinese language is different from other subjects. If you are not completely sure, hastily modifying the answers will often be counterproductive and replace the correct ones with wrong ones, especially affecting the neatness and beauty of the paper. In this case, it is better to keep the first version of the answers.

After lunch, Xu Yun took an unprecedented half-hour nap.

Face mathematics at your best.

After the exam started, Xu Yun got the test paper and took a quick look at it. After confirming that many of the questions were of the type he had done, he felt confident.

"It's a bit difficult, but not very high. It should be able to exceed the score of the last in-class exam."

While whispering softly, he immediately filled in his name, class number, and opened his draft book to start calculating the first multiple-choice question.

Concentration not only made him more concentrated, but also improved his problem-solving efficiency to a certain extent. Combined with the abstract thinking ability that can only be used in mathematics, it is an even more powerful effect. The entire multiple-choice fill-in-the-blank question can be described in two simple words

.

Silky.

That's right.

It's just silky smooth.

His improved abstract thinking ability allows him to quickly find the essence of various mathematical problems and solve them with the simplest ideas.

In addition, he has asked Su Yushan for advice on almost all kinds of questions these days, so it can be said that he has accumulated a lot of knowledge.

Even later he started to like this feeling.

Enjoy the feeling of satisfaction after conquering each question.

Unfortunately, this process did not last until the end of the exam, and he ran into trouble when he reached the final question.

"The final question this time is actually about the derivative function, which is a bit interesting." Xu Yun read the question and the known conditions silently in his mind, and immediately became very interested.

Among all the knowledge in high school mathematics, derivative functions are definitely every student’s nightmare.

The kind that makes it difficult to wake up even if you have a dream.

Because compared with conic sections, which give countless people a headache, the derivative is not only computationally intensive, but the key difficulty is that there is no so-called fixed routine. I don’t know how to solve it, so I can only try to do it.

Even if you improve your abstract thinking ability, it will still take a long time to do it.

But it was this difficulty that aroused his interest even more.

Only by constantly encountering challenges and completing them will your love for mathematics not fade away.

After a brief thought, Xu Yun no longer hesitated and immediately tried to calculate on the draft book according to his own problem-solving ideas.

He spent less time on the previous questions, and it was still early before the paper was handed in, so he didn't have to worry at all and could take his time to answer the final question.

ten minutes later.

Xu Yun turned the draft book full of formulas to the next page, frowning.

"This solution is also wrong."

After trying it himself, he knew that he had underestimated the complexity of this question, especially when coupled with trigonometric knowledge, it was simply a perversion.

I'm afraid even the college entrance examination may not be so difficult.

Seeing time passing by, even Xu Yun could not maintain the calmness just now.

Of course giving up is impossible, there are no such two words in his dictionary.

Faced with such a situation, it seems that there is only one solution left.

"Is it really necessary to use points to put the brain into overclocking state again?" Xu Yun seemed a little hesitant as he thought about this, his biggest support.

Judging from the performance of the last brain overclocking, using it to answer questions is definitely an anti-aircraft cannon to kill mosquitoes, a complete waste.

But I really don’t want to give up on the final question like this.

Just when Xu Yun was struggling with this, he saw the panel appear in front of his eyes, and the information displayed on it surprised him.

"Congratulations to the host for completing the advanced task and obtaining the achievement of master of solving problems. The task reward has been distributed."

"This is……"

"Have I already done thousands of math problems?"

During this period of time, he had been trying his best to complete the task, so much so that he had long forgotten the advanced task at the beginning, and had not actively checked the progress of the completed math problems when he saw the prompt message that suddenly appeared in front of him.

, it was inevitable that he would be too slow to react in time. Then he quickly controlled his consciousness and turned off the prompt information to find the attribute page. After seeing that the points were successfully increased by fifty, and the abstract thinking ability was increased by 15%, his confidence increased again.

reached its peak.

Since it is difficult to solve this problem by improving abstract thinking ability by 15%, then try to improve the effect by 30%.

With this thought in his mind, Xu Yun decisively used this reward in the next second.

As the cool feeling in his temples reappeared, his abstract thinking ability successfully increased to 30%.

The whole person's thinking about mathematics has undergone a qualitative change.

When I returned my attention to the final question, the original obstacles were overcome instantly.

The problem-solving ideas become clearer.

"Use isomorphism with scaling, and take derivatives multiple times, so there should be no problem." Xu Yun checked the calculations in the draft for several minutes, and finally breathed a sigh of relief when he saw that the calculation was finally successfully exported.

It wasn't until the complete process was written down on the test paper that I had the mood to look at other candidates around me.

Apparently he was not the only one who felt the difficulty of the final question.

If you glance over casually, you can see a look of nervousness, irritability, and collapse on his face.

Even when it's time to hand in the papers, most people are still reluctant to leave.

Obviously the final question could not be answered.

Xu Yun asked the invigilator to take away the test papers, took his things and walked out of the examination room, then stood at the guardrail and waited for Li Hui next door to come out.

During this period, when people passed by, the final question was what they heard most.

"The final question in mathematics this time was really weird. It almost summarized all the types and knowledge points of derivatives. I gave up directly after halfway through the math."

"It's all the same. I don't know who asked this question."

"I'm afraid my math score won't be high this time. I just lost the score for a big final question."

"Don't worry, everyone is the same anyway. I just asked my friends in the key class, and almost none of them have made it completely."

Knowing that many of the top students in the key classes failed on this question, Xu Yun was a little moved. He didn't know what the scene would be like when the results were announced at the beginning of the semester.

Just thinking about it makes people look forward to it.

Just when he was secretly happy that he had solved this final question, suddenly an arm was wrapped around his neck, and at the same time a familiar voice sounded in his ears: "You should have handed in the paper early, there is a girl here who refuses to hand in the paper.

, I was scolded and cried by the invigilator."

Hearing this, Xu Yun turned to look at Li Hui and said with a wry smile: "Is there a possibility that she didn't cry because she was scolded?"
