Chapter 19 Teacher Lin, Are You a Devil?
"Fang Chao, how did you choose the answer C for the multiple-choice question of the third question? You just gave the first two simplest steps. Where did the next steps go? We study mathematics, so we can't do it like this It's gimmicky."

"Mr. Lin, the remaining steps of this question use the identity transformation of the radical. If you substitute it in, you don't need the next steps, and you can easily type the answer of C."

"What about this question?"

Fang Chao was a little unhappy and said, "Mr. Lin, are you insulting my IQ? If you change other topics, I am completely willing to explain to you more, but isn't this one the easiest?"

"Don't bullshit me and answer me quickly."

Hei Mian Tan became serious, and Fang Chao didn't dare to be arrogant. He was so afraid of Hei Mian Tan beating people with his hands. It is said that Hei Mian Tan was a bully before he became a teacher, and there was no one in the neighborhood who was not afraid of him. After becoming a teacher, I don't know if the hostility in his bones has subsided. He is only a 16-year-old child, and his body and mind are still in a state of comprehensive development. It is impossible to cause any physical problems at this time.

He cannot allow the future flowers of the motherland to be devastated.

overbearing!

"Mr. Lin, this question can actually be solved with this way of thinking. It doesn't have to be calculated. It just needs to draw an interval diagram and take the maximum value between -4 and 4. Then you can get the Two correct answers, you see, is it very clear? One step in place? Eliminate two wrong answers, and then exclude a double negative value, then there is only one correct answer."

Hearing this, Lin Haifeng saw that Fang Chao had drawn a line next to the multiple-choice question, but you didn't say anything, the devil knows what you are doing, isn't this too abstract?You formed this quadratic function interval diagram directly in your mind?

But I have to say that some people are really geniuses. With just a few tick marks, it is possible to outline a perfect plan curve. Maybe Fang Chao is this kind of person.

I really found a treasure.

This dead child, why didn't he study hard before?
If you have this kind of talent from the first day of junior high school, or if you study hard, you may be able to represent the provincial team to participate in the national mathematics competition, or even represent the motherland to participate in the international league.

"Mr. Lin, there shouldn't be any problem with this test question, right?"

Lin Haifeng said in a deep voice, "Well, basically there is no problem, you can get full marks."

Fang Chao was immediately elated, and it was not easy to get the approval of Heimiantan, "Mr. Lin, I told you that this exam question is very simple, it doesn't look like a math joint competition question at all, it's a bit too childish .”

Lin Haifeng immediately handed out two test papers with a sullen face and said, "If you are so good, then give me these two test papers, one of which is from Hubei, and let me see if it is true. It's so pediatric."

"Wow, Mr. Lin, you are child abuse. It took me more than 40 minutes to finish a test paper. Why don't you let me rest for ten minutes and let me drink a sip of water and eat a piece of bread? A trip to the toilet?"

Lin Haifeng glanced at the time, then tapped his watch and said, "10 minutes, come back and do the questions for me."

"Yes!"

Fang Chao escaped, the black-faced carbon is too scary, why did he torture me like this?Didn't I just show a very high talent in mathematics?But precisely because of this, shouldn't you take care of me, protect me, love me, and praise me to heaven?You are forcing me to do the questions so that I have no time to rest. You are trying to make my brain cells exhausted and die from overwork...

Teacher Lin, you are a devil!

Fang Chao went to the toilet and urinated for more than 30 seconds.

Taking advantage of this time, he entered the system.

[Congratulations to the host, you have made the math teacher look at you with admiration. You have shown an amazing talent in mathematics. You will be rewarded with 50 points for the master. Please continue to work hard. 】

[Congratulations to the host, you have completed a test paper of the National Junior High School Mathematics Joint Competition, with a full score, and 10 points will be rewarded as a master, please continue to work hard. 】

"It turns out that Mr. Lin looked down on me on the surface, but he still recognized me in the mainland. What are you pretending to be, black-faced carbon? If you are excited, you should speak out loudly. Otherwise, how would I know that I am with you?" The place in my heart is so high."

"However, it is a good thing that I get 10 Xueba points for completing a test paper. Usually, it takes me 45 minutes to get 1 point of Xueba points for a class. It takes about 45 minutes, but I can get the Xueba points obtained in ten classes at once, so if I do more test papers, the Xueba points will increase gradually?"

Fang Chao seemed to have discovered a shortcut to gain Xueba points.

Happy!
He took another look at the Xueba points: 1058.

After getting out of the toilet, he breathed in the freshest campus oxygen, and then he returned to the class and took out bread and water.

After 10 minutes, no more than a second and no less than a second, the math teacher gave the absolute sensitivity to numbers in academic terms, "Start doing the questions!"

Fang Chao didn't dare to neglect, and started to do the questions.

Let's start with the simple one first, and then do Hubei's...

Fang Chao thought about it, and immediately started to work on the questions.

The multiple choice questions are still very simple, there is no pressure at all.

Fill in the blanks, brush up the water.

Answering the questions, the first two questions are not difficult, the third question, um, is a little interesting, it is only given a triangle and two x-axis and y-axis, but it is necessary to calculate the maximum range that can be run between the two axes area.

Interesting, very interesting, and finally a little challenging.

Fang Chao bit the tip of the pen with his mouth, thinking about the problem-solving ideas over and over again in his mind. If it was just to calculate the area, then the problem would not be a big problem. Now that there are more intervals, the difficulty will be doubled all of a sudden.

Not far away, Lin Haifeng watched Fang Chao fall into a state of 'contemplation', and a faint smile appeared on the corner of his mouth, "Boy, let's see what you can do. No, you will still be defeated by the math problems..." …Mathematics is not as simple as you think.”

Fang Chao was indeed caught in the dilemma of solving the problem. There was still a "problem solving idea" in the system that was not used, but he did not use it. After all, it is not a regular game. Don't waste such good things. solve problems.

It can also be seen from this aspect that although the mathematics has been promoted to level 1, the logic is still lacking. At this time, his eyes looked out the window.

The sparrows outside the window are chattering on the poles.

It seems to be saying: Look, there is stupid ×.
