"Teacher, I'm applying to do the question!"

The teacher reluctantly restrained his seriousness, "Okay, I'll give you a chance to make up for it." ”

Su Qianli came up and picked up the chalk, didn't even look at the topic, and wrote it slowly.

The teacher was still lecturing, he was the kind of teacher who paid attention to efficiency, and when Su Qianli was doing the questions on the blackboard, he was also consolidating the knowledge points for the students.

But halfway through the lecture, I suddenly found that most of the students didn't pay attention to him, and their attention was on the blackboard, and some of them were hiding their mouths and smiling, and some of them suddenly realized.

The teacher realized that something was wrong, and when he turned around, he was also blindfolded, and his jaw couldn't be closed, so he kept hanging, and he was so shocked that the textbook in his hand was smashed out!

After so many years of teaching, he has never met such a student!

The entire blackboard was first written by Su Qianli with a (x2+y2-1)3+x2y3 = 0, and then used a huge layout to draw the image of this function, which is actually a big heart!

This is the famous mathematician Descartes invented the line of functions, by confessing to the princess.

I won't learn this part of high school mathematics, and Su Qianli is obviously well-read, so he only knows about this function!

This is still a thing worth encouraging, but the problem is that Su Qianli should not do this question at all!

He was so angry that his neck was thick, panting from his nose, he really loved and hated this student, he still used a lot of heart for mathematics, but he hated it so much that he was late, inattentive, and now he is still in the opposite tune, which is obviously challenging his authority again and again!

Of course, the ingredient of hatred must completely overwhelm love, and it must completely overwhelm reason!

Xia Qing was already completely stunned, swept over the line, and then looked blankly at Su Qianli on the podium, who was constantly giving up and compensating.

To be honest, Su Qianli's move made Xia Qing can't help but think of Su Qianli's family's Erha.

There really is a kind of owner, what kind of dog.

It's the same with her family's Erha, tearing up the house, and when Su Qianli comes back and finds that it has done something wrong, it will be especially careful to sell the pitiful, racking its brains to please the owner, and strive to forgive.

"Su Qianli, get out of the penalty station for me!" The teacher resisted the urge to swear and pointed outside.

Su Qianli glanced at Xia Qing with pitiful eyes again.

Her first confession was not given to Brother Jue, but to Qingqing, and she used the method of "comparing hearts", which is sincere enough, right?

I hope Qingqing won't be angry with her anymore.

Qingqing, I'm sorry, I know it's wrong!

As soon as she walked to the door, she suddenly heard a voice in the classroom, "Teacher, I'll accompany her to the punishment station!" ”

Su Qianli didn't even look back, she knew who it was.

"But you don't need to ...... at all"

"Yes, teacher, I was distracted in class just now, you read my book." Xia Qing raised her textbook, and the teacher found that there were two little people drawn on her book, which were the Q version of her and Su Qianli.

Su Qianli's eyes were sour, and she almost cried.

And the teacher has never seen this kind of divine operation, Xia Qing has been drawing in the book for so long, he didn't see it? This really slapped him in the face of being a teacher for so many years!

……

Outside the classroom, Su Qianli and Xia Qing were standing straight, but in fact, the sun was going down, the scenery was very beautiful, and a fresh wind was blowing one after another.

This has to be thanks to the penalty station, otherwise you wouldn't be able to enjoy such a scenery.
