Sister Flower's Bodyguard

Chapter 35

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

Of course, in the process of solving problems, you must constantly change unknown quantities into known quantities, and then combine them with each other, which requires strong logical thinking. After all, if some formulas are wrong, the result you calculate may be wrong.

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

With such speed and reflexes, even Han Wei couldn't help but nodded.

But what about the other side?

Pan Hongsheng was embarrassed. There was no way to do the questions by himself. Every time the old man took back a stack of papers for the test, he asked himself to finish writing in one day and one night, and then went out with the completed papers to talk about grading, but every time he came back The answers are all the same: "There are not many mistakes, but they are all sloppy. Going out and chopping down three trees is a punishment!"

Of course, the rebellious Pan Hongsheng also tested it, but after that time, when the paper was given to him again, it was taken away like a robbery.

Not for anything else, but because I fell asleep while writing, and then arranged the papers in the order of finished, unfinished, finished... and handed it to the old man nervously.

But when he came back, he still said the same sentence: "There are not many mistakes, they are all sloppy!"

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

Pan Hongsheng must have been furious about this kind of thing. After returning home, he questioned his unscrupulous old man, but the answer he received was a cannon punch and Bengya punch. It was not until he became a panda eye that he heard the old man's faint words : "Don't question me, the test paper will be reduced by half in the future, if you can't finish it, you will still be punched!"

So Pan Hongsheng himself didn't know which of the questions he did were right and which were wrong.

What he can use is to use three methods to calculate the answer to a question. If the three answers are the same, then the question is correct. This is why Pan Hongsheng wrote himself very small and stuck to the left side of the blackboard. s reason.

In the seats, many students had already started to discuss, but Han Wei didn't care. He just looked at Pan Hongsheng and then at Su Ya with a smile, and a hint of surprise and relief flashed in his eyes from time to time.

"Hey, do you think the new one can be made?" A tall man asked Gao Feng.

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

"I can't, it seems that you two are fine, why don't you shit together!" the tall man muttered, and then did the question again.

In other corners, many people also began to discuss Pan Hongsheng's problem solving.

Of course, most people are still willing to embarrass Pan Hongsheng for no other reason. If they know that the transfer is a high-achieving student, I am afraid that these rich children will feel unhappy for a while.

"Tang Jiajia, is Pan Hongsheng good at math?" Han Wei asked with a flash of light in his eyes.

"Mathematics? I don't know, I know he is good at English!" Tang Jiajia blushed, as if she felt that the teacher's question to Pan Hongsheng was ambiguous, she lowered her head and picked her fingers.

"This student is a jade!" Han Wei said with a sigh, and on the other side, Su Ya had already lightly put the chalk on the podium, and sat back with a sigh of relief.

"Sister, what can a country bumpkin do? You won't be blah blah blah!" Su Xue handed Su Ya a note.

"Probably not. I read it. He calculated the same answer as me before, and...it seems to be a lot faster than me, but I don't know why he is still writing it now." Su Ya threaded the note back.

"Even if you write it out, you're blind!"

On the podium, Pan Hongsheng had already wiped his sweat for the third time. The answers he had calculated with the two methods before were the same, but why was the third method different?

"Could it be that this quadratic function can't be solved in this way?" Pan Hongsheng thought of all the knowledge points he had learned in high school, but he couldn't figure out how to write the next step. He didn't know that the biggest difficulty of this question was in this A trap is set somewhere.

"Damn it, I don't care, I have to write why!" Gritting her teeth, Pan Hongsheng wrote two words on the blackboard: Proof!

"Haha...the proof is written on the function problem!"

"Why did this guy write so much, you can't write or copy!"

"He wrote the two words of proof, which can only prove that his brain is broken!"

The class suddenly became noisy, and Han Wei's eyes were filled with confusion.

The child's previous two algorithms, one is more conservative step by step to finally get the answer, although it looks a bit cumbersome, it can be seen that the child is very familiar with the concept of knowledge.

The second method is relatively radical, and some knowledge points that have not been learned so far have been interspersed in the middle.

But what happened the third time?prove?What to prove?

Han Wei stood up from Pan Hongsheng's seat, and the class immediately became quieter, but when Han Wei walked in and saw the four words on the bottom of the proof on the blackboard, which were blocked by Pan Hongsheng's body, his expression suddenly changed. Change.

"Gao La Curve!"

Taking a deep breath, Han Wei said directly: "Okay, classmate Pan Hongsheng, time is running out, if this method can't be worked out, go back first!"

"Oh." Sighing helplessly, Pan Hongsheng slowly walked back to his seat, sat on the chair, frowned, picked up the pen and continued to draw. He didn't see that the math teacher Han Wei blocked the moment he left. After erasing the word "Gao La Curve", he wiped it off without any trace, and looked at Pan Hongsheng again with a hint of surprise in his eyes!

"Okay, students, let's start looking at the questions!" Han Wei took Su Ya's writing and began to explain. Most of the senior high school students listened carefully to the pit where he fell, but it didn't take long. Some interested people discovered that on the left side of the blackboard, the first method written by Pan Hongsheng was actually similar to Su Ya's. Although it was a bit more complicated, it was more clear to people.

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

"In the first way, if you memorize it by rote, someone with a heart may be able to figure it out, but in the second way, you are required to read it, because you haven't learned the above knowledge points yet!"

"That is to say, Pan Hongsheng has mastered all 274 high school mathematics knowledge points. If there is no accident, the number one student in the college entrance examination mathematics market should be in our class!"

"Hiss..." All the students looked at Pan Hongsheng unanimously, with a look of shock on his face, while Pan Hongsheng looked at his red cross in a little astonishment, frowned and wrote on the draft paper again.
