The school grass wants to marry me

Chapter 911 Yan Xiaoqiao’s New Friend (1)

The classroom was noisy, and the students were fighting like a scourge.

The door of the classroom was pushed open, and a tall and tall man with glasses who looked a bit like Mr. Hu Shi, a literary predecessor, came in, and the classroom was suddenly quiet.The classmates are afraid of this teacher, he teaches terrible mathematics, and more importantly, he is their class teacher.

"Attend class."

"Hello teacher."

"Hello students."

The little girl was sitting on the right side of the podium, the fourth row by the window, and Ding Xinghai was sitting behind the little girl. Every time the little girl stood up and sat down, the little girl would subconsciously turn her head and move The moment he raised his head from his bench, he pretended to casually look in Ding Xinghai's direction, and then began to listen to the class with great joy.

I don't know when it started, if one day I forget to look back in class, I will feel uncomfortable for the whole class.

Black and white blackboard.

“解不等式：（x的平方-9）（x的平方-3x-4）＞0?2.m取何范围时，关于X的方程x的平方-2（m+2）x+m的平方-1=0?？这道题谁会啊？”黑板前，班主任兼数学老师黑着脸严肃的指着黑板问道。

There was no sound under the podium, and the students agreed one by one to start a competition: to see whose neck is strong enough to be lowered even lower.

The supervisor at the podium held the blackboard eraser and patted the desk: "If I see any of you who don't look at me, I will call their names."

They raised their heads in unison, stared at the class teacher with wide eyes, and then said silently in their hearts: "Don't call me, don't call me."

I don't know if I heard it wrong. When Hu Chuchu heard her name, the students around her breathed a sigh of relief, and Hu Chuchu stood up tremblingly: "Teacher, this topic is really too difficult. Can you change it?" simple."

"If you don't, you won't, and you're still making excuses." The head teacher said seriously.

There was laughter all around.

"Ding Xinghai, tell me how to solve this problem?"

Oh my god, the teacher actually called Ding Xinghai's name after calling his own name. Could this be the legendary fate?It seems that I, Hu Chuchu, and Ding Xinghai are a natural match.

"Teacher, it is an image similar to the sine and cosine functions. Draw it on the number axis. For example, if the value of X is to the left of -3, then the equation is positive. Draw a line above the number axis to the left of -3. A total of Just discuss the positive and negative situations on the left of -3, between -3 and -1, between 1 and 3, between 3 and 4, and on the right of 4. So the answer to this question is (negative infinity, -3) And (-1, 3) and (4, positive infinity)." Ding Xinghai finished all this in one breath.

then.

The head teacher in the classroom showed a hidden smile: "You should think about Ding Xinghai's study and study more. If you are like you, do you still want to go to college in the future? Ding Xinghai, you answered well, sit down."

"Think," the naughty students said in response.

The homeroom teacher gave those students a blank look, and then said, "Hu Chuchu, sit down too, and listen to the class carefully. What can you do when you grow up if you don't listen to the class well?"

Hu Chuchu sat down without being angry at all, and smiled brightly, thinking that the head teacher would read Ding Xinghai's name immediately after reciting his own name, and he even felt happy to breathe.Hu Chuchu secretly vowed: I must study mathematics hard in the future, and I must emulate Ding Xinghai, so that I will have a lot of common language in the future.
