Chapter 1443 No Wonder...

Occasionally someone saw it and was about to sigh, but suddenly swallowed the words that came to his mouth when he saw the deep and cold black eyes of his boss Mo Cheng, covered his eyes and muttered: "I didn't see anything...I didn't see anything Didn't see..."

As soon as Si Mocheng left, Tang Ziyan called him to stop, wanting him to do a good job of himself.

However, he left without looking back.

Tang Ziyan was so angry that she had no choice but to turn her mind on Li Xiaoxiao.

"Xiaoxiao, how do you do this question?" Tang Ziyan asked in a soft voice.

Li Xiaoxiao looked up at the title, and said in a leisurely manner, "Seek the second-order guide first."

Tang Ziyan's hand that was about to write stopped again.

Well, that's right.

She doesn't understand what it means to seek a second-order derivative.

Seeing her devastated, Li Xiaoxiao rolled her eyes, feeling inexplicably happy in her heart.

Li Xiaoxiao's steps were written in more detail than Simocheng's, so it took a little longer.

But soon, she asked for the answer, checked again and felt that it should be correct, then put down the chalk and returned to her seat.

Tang Ziyan's face turned ashen when she saw the two of them finish their work one after another.

Li Xiaoxiao is a scheming bitch!

Didn't you say no?

Why do you write so much?

What else is there to ask for a second-order guide, is it to embarrass yourself on purpose?

Tang Ziyan forced herself to withdraw her thoughts, and looked at the big Jiezi under the title, feeling extremely embarrassed.

And her friend was in a better situation than her. Although she didn't pay attention to the class, she still listened to a few words, and the topic was simpler than Tang Ziyan's, so she made a score of three or four.

Therefore, there are four questions on the entire blackboard.

For a moment, only Tang Ziyan's title was blank, especially empty.

"How to do this question?" Tang Ziyan had no choice but to focus on her friend.

The girl looked up, shook her head nervously and said, "I can't either, this is a high number..."

"Trash, you don't know what you wrote yourself!" Tang Ziyan was furious.

The girl felt a little wronged: "I... I happen to know a little bit about this question."

At this time, the teacher had already walked around the classroom, returned to the podium, first looked at what Li Xiaoxiao and Si Mocheng had done, and then his eyes fell on Tang Ziyan and the girl's topic.

Seeing that Tang Ziyan hadn't finished writing, the teacher immediately opened her mouth to prompt: "For the third question, first seek the second-order guide."

As soon as the teacher opened his mouth, many people looked up.

Hearing this word again, Tang Ziyan's expression became even uglier.

Seeing that she hadn't written for a long time, the teacher frowned and said, "Why don't you write?"

Tang Ziyan had no choice but to turn around and said, "Teacher, I don't quite understand what seeking a second-level guide is..."

The teacher was also a little surprised, and frowned, "Which department are you from? This is a very basic step. I walked around the stage just now, and more than 90% of the students have done it."

Tang Ziyan kept losing face, but she still pretended to be calm and said, "I'm from the School of Art and Media."

The teacher didn't respond too much, and said lightly: "No wonder..."

Tang Ziyan didn't have time to understand the meaning behind this sentence, so she heard the teacher say: "Okay, you can go back, although high math may not be of much use to you in the future, but since you are here to attend the class, I still hope that you can have a good time." What you have gained, otherwise wasting this time is self-deception and meaningless.”

Tang Ziyan's face turned blue and purple, which was extremely ugly.

It wasn't until he returned to the audience to do a good job next to Si Mocheng that he felt that the contrast between the questions on the blackboard was so great.
