The most important thing about solving a math problem was to get straight to the point. If one could directly find out where the test point of a problem was and use every knowledge point, a problem could basically be solved.
Of course, in the process of solving the problem, one had to constantly turn the unknown into known quantities and then combine them with each other. It required a very strong logical thinking. After all, if some formulas were wrong, the result calculated by you might be wrong.
Although Su Ya was a girl, she had developed her own skills after doing the questions for a long time. Coupled with the teacher's request, she went straight to the point and drew a few draft function images before quickly answering them.
Even Han Wei couldn't help but nod in approval at his speed and reaction.
But what about the other side?
Pan Hongsheng was embarrassed. He did not have any rules when he did the questions. Every time the old man brought back a stack of papers for the test, he would ask him to finish it in a day and a night. Then, he would take the completed papers out and say that he was going to mark the papers. However, the answer was always the same every time he came back: "I didn't make many mistakes, but they were all small mistakes. Going out to cut down three trees is a punishment!”
Of course, the rebellious Pan Hongsheng had also taken the test. However, after that, he snatched the test away when he was given another one.
It was because he had once fallen asleep while writing. Then, he arranged the papers according to the order of completed papers, unfinished papers, completed papers…and then handed them to the old man nervously.
But when he came back, he still said the same thing: "There aren't many mistakes. It's all because of carelessness!”
Then, Pan Hongsheng groped his way to the top of the mountain where the old man was marking the papers. He found that a few children in the village were using his papers to…fly kites!
Pan Hongsheng would definitely be furious about such a thing. When he went back, he would question his heartless old man, but the answer he got was a series of punches and punches. It was not until he had panda eyes that he heard the old man say,"Don't doubt me. In the future, if you can't finish half of the papers, you'll still be beaten up!”
Therefore, Pan Hongsheng didn't know which questions he did were right and which were wrong.# Baidu search (hand typing bar) Read the latest chapter of this book #
What he could do was to use three different methods to calculate the answer to a question. If all three answers were the same, then the question would be correct. This was also why Pan Hongsheng had written himself very small and stuck close to the left side of the blackboard.
Quite a number of students had already started discussing among themselves, but Han Wei did not care. He only smiled at Pan Hongsheng and then at Su Ya. From time to time, a trace of astonishment and gratification flashed across his eyes.
"Hey, do you think that newcomer can make it?”A tall man asked Gao Feng.
"How would I know? I've never seen him do his homework!”Gao Feng shrugged and said with a smile.
"No way. You two look pretty good. Aren't you shitting together?”The tall man muttered and then did the questions again.
Many people in other corners also began to discuss Pan Hongsheng's solution.
Of course, most of them were still willing to embarrass Pan Hongsheng. If they knew that the transfer was a top student, they would probably be unhappy.
"Tang Jiajia, is Pan Hongsheng good at math?”Han Wei's eyes flashed as he asked.
"Mathematics? I don't know. I know that his English is very good!”Tang Jiajia blushed. She seemed to think that the teacher's question to Pan Hongsheng was very ambiguous. She lowered her head and dug her fingers.
"This student is a jade!" Han Wei sighed and said. On the other side, Su Ya had already gently placed the chalk on the podium and sat back down with a long sigh.
"Sister, do you know how to cook? Don't tell me he's making a fuss over there!" Su Xue handed Su Ya a note.
"I don't think so. I've seen it. He calculated the same answer as I did, and…he seemed to be much faster than me, but I don't know why he's still writing.”Su Ya put the note back on.
"Even if you write it, it's just a guess!”
On the podium, Pan Hongsheng was already wiping his sweat for the third time. The answer he had calculated using the two methods was the same, but why was the third method different?
"Could it be that this solution can't be used for this cubic function?”Pan Hongsheng thought of all the knowledge he had learned in high school, but he could not figure out what to do next. He did not know that the biggest difficulty of this question was to set a trap here.
"Damn it, I don't care. I have to write a reason no matter what!”Gritting his teeth, Pan Hongsheng wrote two words on the blackboard: Proof!
"Haha…I've written the proof for the function question!”
"Why did this guy write so much? If you don't know how to write, why don't you copy?”
"The fact that he wrote the word proof can only prove that his brain is broken!”
The class suddenly became noisy, and Han Wei's eyes were filled with puzzlement.
The child's previous two methods of calculation, one was more conservative, one step at a time, and finally came up with the answer. Although it looked a little cumbersome, it could be seen that the child was very familiar with the concepts of knowledge.
The second method was relatively more radical, and there were already some knowledge points that he had not learned yet.
But what was going on the third time? Proof? What was he trying to prove?
Han Wei stood up from Pan Hongsheng's seat, and the class immediately quieted down. When Han Wei walked in and saw the words on the blackboard that were blocked by Pan Hongsheng's body, his expression changed.
"A high-pull curve!"
Han Wei gasped and said,"Alright, Pan Hongsheng, there's not much time left. If you can't figure out this method, you should go back first!”
"Oh." Pan Hongsheng sighed helplessly and slowly walked back to his seat. He sat on the chair and frowned as he picked up the pen and continued to draw. He did not see that the math teacher, Han Wei, had stood in front of the words " high-pull curve " the moment he left and wiped it off without leaving a trace. When he looked at Pan Hongsheng again, there was a hint of surprise in his eyes!
"Alright, students, let's start looking at the questions!”Han Wei began to explain what Su Ya had written. Most of the third-year students listened attentively to the pit where they had fallen. However, not long after, someone noticed that the first method written by Pan Hongsheng on the left side of the blackboard was actually similar to Su Ya's. Although it was a little complicated, it was more obvious.
"Alright, now let's see Pan Hongsheng's method.”As Han Wei spoke, he picked up a red chalk and drew a huge circle on Pan Hongsheng's second method.
"For the first method, if you memorize it by heart, you might be able to figure it out. But for the second method, you have to read it because you haven't learned the knowledge points on it yet!”
"In other words, Pan Hongsheng has already mastered all 274 high school mathematics knowledge points. If I'm not mistaken, the top student in the college entrance examination should be in our class!”
" Hiss..." All the students looked at Pan Hongsheng in shock. Pan Hongsheng looked at his red cross in shock and frowned as he wrote on the draft paper again.
