"Fang Chao, how did you choose the C answer for this third multiple-choice question? You just gave the first two easiest steps, where did the next steps go, we who study mathematics, can't make such bells and whistles. ”

"Mr. Lin, the remaining steps of this question use the identity transformation of the root type, you substitute him into it, is there no need for the next steps, and it is very easy to type the answer of C."

"What about this one?"

Fang Chao was a little unhappy and said, "Teacher Lin, are you insulting my IQ?" I'd love to explain more to you if you were to change to another topic, but isn't this one the easiest? ”

"Don't give me a, answer me quickly."

The black face carbon became serious, Fang Chao suddenly didn't dare to be arrogant, he was so afraid that the black face carbon would hit people, it is said that the black face carbon was a bully before he became a teacher, and there was no one in the ten-mile neighborhood who was not afraid of him, and later changed his evil and became a teacher, but he didn't know if the anger in his bones had subsided, he was just a sixteen-year-old child, his body and mind were still in a state of all-round development, and he couldn't let his body have any problems at this time.

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

Overbearing!

"Mr. Lin, this problem can actually be solved with this way of thinking, you don't have to calculate, you just need to draw an interval graph, and take out the maximum value between -4 and 4, then you can get the two correct answers, you see, is it very clear? One step? Eliminate the two wrong answers, and one more double negative value, and then there is only one correct answer. ”

When Lin Haifeng heard this, he really saw Fang Chao draw a line next to this multiple-choice question, but you don't say it, the ghost knows what you're going to do, it's too abstract, right? You formed this quadratic interval graph directly in your mind?

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

I really dug up a treasure.

Why didn't this dead kid study hard before?

If you have such a talent since junior high school, or if you study hard, you may be able to represent the provincial team in the national mathematics competition, and maybe even represent the motherland in the international league.

"Teacher Lin, there should be no problem with this exam question, right?"

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

Fang Chao was suddenly elated, it was not easy to get the praise of the black face carbon, "Teacher Lin, I told you, this exam question is very simple, it doesn't look like a topic in a joint mathematics competition at all, it's a bit too pediatric." ”

Lin Haifeng suddenly handed out the two test papers with a calm face and said, "If you are so good, then these two test papers will also be taken for me, one of which is from Hubei, let me see if it is really so pediatric." ”

"Wow, Mr. Lin, you are abusing children, I just spent more than forty minutes to complete a test paper, and you won't let me rest for ten minutes or so, let me drink a sip of water, eat a piece of bread, and go to the toilet by the way?"

Lin Haifeng glanced at the time, then tapped his watch and said, "Ten minutes, roll back for me to do the question." ”

"Yes!"

Fang Chao escaped, the black-faced carbon was too terrifying, why did he torture me so much? Haven't I just shown a great talent in mathematics? But because of this, shouldn't you take care of me, protect me, love me, and hold me up to heaven? You're forcing me to do the questions so much now that I don't have time to rest, you want to make all my brain cells consume and die of overwork......

Teacher Lin, you are the devil!

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

Taking advantage of this time, he entered the system.

[Congratulations to the host, you have made the math teacher impress you, you have shown amazing talent in mathematics, and you will be rewarded with 50 points for top students, please keep up your efforts.] 】

[Congratulations to the host, you have completed a National Junior High School Mathematics Joint Competition test paper, with a full score, and 10 points will be awarded to the top students, please make persistent efforts.] 】

"It turns out that Mr. Lin is disdainful of me on the surface, but the mainland still recognizes me very much, what are you pretending to be black-faced carbon, if you want to be excited, you should say it out loud, otherwise how do I know that I have such a high status in your heart."

"But after completing a test paper, there are 10 points of Xueba, which is a good thing, usually, I can get 1 point of Xueba points in forty-five minutes in the last class, although it takes almost forty-five minutes to complete a test paper, but I can get the Xueba points obtained in ten classes at once, so if I do more test papers, won't the Xueba points go up gradually?"

Fang Chao seemed to have found a shortcut to get the points of a top student.

Happy!

He glanced at the top student score again: 1058.

After getting out of the toilet and getting a breath of the freshest oxygen on campus, he went back to class and brought out bread and water.

Ten minutes later, no more than a second, no less than a second, the math teacher gave the absolute sensitivity of the numbers on the academic side, "Start doing the problem!" ”

Fang Chao didn't dare to slack off and began to do the question.

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

Fang Chao thought about it and immediately started to do the question.

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

Fill in the blanks, brush up the water.

The first two questions are not difficult, and the third question, well, is a little interesting, wow, it is just a triangle and two x and y axes, but it is necessary to calculate the maximum area between the two axes.

It's fun, it's fun, it's finally a little bit more difficult.

Fang Chao bit the tip of the pen with his mouth, thinking of the idea of solving the problem over and over again in his mind, if it was just to calculate the area, then it would not be a big problem, now that there is an extra interval, then 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 couldn't help but appear on the corner of his mouth, "Boy, look at what you can, no, you still have to obediently defeat under the math problem...... Math isn't as easy as you think. ”

Fang Chao did fall into the dilemma of solving the problem, there was still a 'problem solving idea' in the system that was not used, but he didn't use it, now it is not a regular competition after all, don't waste such a good thing, you should solve the problem by relying on your own ability.

From this aspect, it can also be seen that although the mathematics has been improved to level 1, the logic is still lacking, and at this time, his eyes are looking out the window.

Sparrows outside the window, beaked on a telephone pole.

As if to say: look, there is a stupid ×.
