Chapter 35 The champion!

The most important point in solving mathematical problems is to directly insert the theme. If you can directly find out where the test point of a question is, every knowledge point can be used, and a question can basically be solved.

Of course, in the process of solving the problem, it is also necessary to constantly turn unknown quantities into known quantities, and then combine them with each other, which requires strong logical thinking. After all, some formulas are wrong, and the result you calculate may be wrong.

Although Su Ya is a girl, she also has some of her own skills in doing questions for a long time. Coupled with the teacher's on-demand, she drew a few draft function images directly, and then began to answer them quickly.

This speed and response, even Han Wei couldn't help nodding.

But what about the other side?

Pan Hongsheng was embarrassed. There was no way to do the question by himself. Every time the old man took back a roll of papers, he let himself finish it in a day and a night, and then took the finished papers and went out to read the papers, but every time he came back, the answer was the same: "There are not many mistakes, but they are all careless. Go out and cut them. Three trees are a punishment!"

Of course, the rebellious Pan Hongsheng also tested it, but after that time, when he gave him the paper, he took it away like grabbing it.

For nothing else, it's because I fell asleep once when I wrote it, and then arranged the paper in the order of finished, unfinished, finished... and then handed it to the old man tremblingly.

But when I came back, I still said this sentence: "There are not many mistakes, they are all careless!"

Then, Pan Hongsheng groped and climbed to the top of the mountain where the old man was reading the papers, and found that several children in the village were using his papers to fly kites!

Pan Hongsheng must be furious about this kind of thing. After going back, he questioned his unscrupulous old man, but what answered him was a cannon fist and a tooth collapse fist. It was not until he became a panda's eye that he heard the old man's faint words: "Don't question me. In the future, the paper will be reduced by half, and it will still be a cannon that can't be finished. Fist!"

So Pan Hongsheng doesn't know at all whether the questions he did are right or wrong.

What he can use is to calculate the answer to one question in three ways. If all three answers are the same, then the question is right. This is why Pan Hongsheng wrote himself very small and close to the left side of the blackboard.

On the seat, many students have begun to talk about it, but Han Wei didn't care. He just looked at Pan Hongsheng with a smile and Su Ya, with a trace of astonishment and relief flashed from time to time.

"Hey, do you think the newcomer can make it?" A tall man asked Gao Feng Dao.

"How do I know? I haven't seen him do his homework!" Gao Feng shrugged his shoulders and said with a smile.

"I can't. It's good to see you two. Why don't you take a shit together?" The tall man muttered, and then did the question again.

And many people in other corners began to talk about Pan Hongsheng's problem solving.

Of course, most people are still willing to let Pan Hong rise to be embothes, for nothing else. If they know that it is a top student, I'm afraid these rich children will be upset.

"Tang Jiajia, is Pan Hongsheng good at math?" A trace of brilliance flashed in Han Wei's eyes and asked.

"Mathematics? I don't know. I know his English is very good!" Tang Jiajia blushed and seemed to feel that the teacher's question about Pan Hongsheng was very ambiguous. She lowered her head and scratched her fingers.

"This student is a Yupu!" Han Wei sighed and said, and on the other side, Su Ya had gently put the chalk on the podium, and a man took a breath and sat back.

"Sister, can the country bumpkin do it? You won't be shouting there!" Su Xue handed Su Ya a note.

"I don't think so. I read it. He calculated the same answer as me before, and... It seems to be much faster than me, but I don't know why he's still writing now." Su Ya put the note back.

"Even if it is written, it is still blind!"

On the podium, Pan Hongsheng has wiped his sweat for the third time. The answer he calculated with two methods before is the same, but why is the third one different?

"Is it possible that this quadratic function can't be solved with this solution?" Pan Hongsheng tried to do everything he had learned in high school, but he didn't figure out how to write next. He didn't know that the biggest difficulty of this question was to set a trap in this place.

"What the world, I don't care, why do I have to write a reason!" Gritting his teeth, Pan Hongsheng wrote two words on the blackboard: Proof!

"Haha... The function question is written as proof!"

"Why does this guy write so much? You can't write or copy!"

"He wrote two words to prove that his brain is broken!"

The class suddenly became noisy, and Han Wei's eyes were also puzzled.

The child's previous two algorithms, one is relatively conservative step by step and finally get the answer. Although it looks a little cumbersome, it can be seen that the child is very familiar with the conceptual things of knowledge.

The second method is relatively radical, and it has been interspersed with some knowledge points that have not been learned so far.

But what's going on for the third time? Proof? What do you want to prove?

Han Wei stood up from Pan Hongsheng's position, and the class was immediately quieter. When Han Wei walked in and saw the four words on the blackboard that were blocked by Pan Hongsheng's body, his face changed.

"High-pull curve!"

Taking a cold breath, Han Wei said directly, "Okay, Pan Hongsheng, time is running out. If you can't figure out this way, go back first!"

"Oh." With a helpless sigh, Pan Hongsheng slowly walked back to his position, sat on the chair, frowned and picked up the pen to continue to stroke. He didn't see that the math teacher Han Wei blocked the four words 'high-pull curve' at the moment he left, wiped it down without a trace, and looked at Pan Hongsheng's eyes again. A little more astonishment!

"Okay, students, let's start reading the questions!" Han Wei began to explain with Su Ya's writing. Most of the senior high school students listened attentively to the pit he had fallen to, but it didn't take long for someone to find that the first method written by Pan Hongsheng was similar to Su Ya. Although it was a little complicated, it was more obvious.

"Okay, now let's take a look at Pan Hongsheng's method." Han Wei said, picked up a red chalk and drew a huge circle on Pan Hongsheng's second method, and then said faintly.

"The first method, you may be able to figure it out by rote, but the second method, you have to read it, because you haven't learned the above knowledge so far!"

"That is to say, Pan Hongsheng has integrated all 274 mathematical knowledge points in high school. If nothing unexpected happens, the top math market in the college entrance examination should be in our class!"

"Hiss..." All the students looked at Pan Hongsheng with a shocked face, while Pan Hongsheng looked at his red fork with slight consternment, frowned and wrote on the draft paper again.
