The system forces me to study hard every day

Chapter 475: The Scientific Research Boss She Has Both Civil and Military Skills (40)

Su Xiyu sighed helplessly after hearing her words, and then said.

"People change, don't they?"

Yunxiu was stunned when she heard Su Xiyu's words. She always felt that there was something more in Su Xiyu's words, but she also felt that she was thinking too much.

Anyway, until the next class, Yunxiu didn't say a word.

The next class is mathematics. The teacher handed out a paper as soon as she came up. With the experience of doing it for a day and a half at noon, she worked hard to speed up, and then closed the paper when she reached the end of the third page. .

Just when she thought it was over, the teacher handed out the second paper. The questions in this paper were not in the standard format, and the difficulty of each question was visible to the naked eye.

"It's still the same, let's do a set of super-syllabus questions, and you should do your best. After all, this set of questions is relatively difficult, and it's just for you to do a little psychological preparation for the college entrance examination.

Let me reiterate again, there must be more or less super-syllabus questions in the college entrance examination, you are right to do a little bit, ang! "

After the teacher finished speaking, everyone in the class responded tacitly to express that they heard it, but in fact no one looked up, and they all bowed their heads and worked on the questions.

Su Xiyu also picked up the pen, looked at the question types in front of her, and pursed her lips slightly, she felt...

It seems a little bit simple...

It must be her illusion.

Su Xiyu picked up the pen and began to write and draw in the draft book, and did three or four questions in a short while.

The teacher was originally doing the questions there, but when he heard the non-stop brushing sound of the pen tip falling on the paper beside him, he froze for a moment, and then looked over.

It's normal to keep writing while doing questions, but it's not right if you don't even think about writing all the time!

After all, this is mathematics, not language!
The math teacher actually wanted to say something to her, but when he was thinking about solving the problem, the most taboo thing was that his thoughts were interrupted, so he didn't say anything in the end.

He thought for a while, then stood up silently, walked behind Su Xiyu, looked at it, and was stunned for a moment just after reading a question.

This question...

Is this the solution?

The teacher was stunned for a moment, then returned to his desk, picked up his paper and read it. After confirming that the answers were consistent, he couldn't sit still.

Obviously Su Xiyu's algorithm is much simpler than his!
The teacher seemed to have dug up a treasure, and walked behind Su Xiyu, and followed the train of thought one by one, and then he got stuck.

How did the following step come about?
He couldn't understand what was written in this step!
Could it be that he forgot some formulas when he was old?

It shouldn't be, he has been taught this way all these years, and he hasn't forgotten any formulas!

So what's going on...

Just when he was puzzled, Su Xiyu had finished the last question and stopped writing. It just so happened that the bell rang for the end of get out of class. Su Xiyu was just about to stretch when she realized that The teacher standing by.

???

When did the teacher stand here?
"Student, can you tell me what you think about this step? I don't remember such a formula!"

Su Xiyu looked at the formula he was pointing at, and was slightly stunned for a moment. After contacting the front and back, she understood what was going on.

"This one, I deduced this formula by using that function formula, you see, that's how it was done..."
