Teacher Xu, Please Take Care of the Reckless Students in Your Class

He was still muttering, "Sure enough, the questions that Mr. Xu gave are level!"

"Compared with what Teacher Zhao wrote, it is worth our efforts!"

"Indeed, looking at Mr. Zhao's problems, I feel a bit anticlimactic, but it's Mr. Xu's work that is eye-catching."

"That's the question! I'm so excited! I haven't felt goosebumps like this in a long time!"

A classmate said so, but everyone in the class said so, and they were all gearing up for it.

Zhang Ruiyun's eyes twitched.

Before, he still had doubts in his heart, whether these 20 people have become so powerful, and now he has the answer.

"hiss……"

Take a deep breath.

Zhang Ruiyun also looked up at the blackboard.

"Indeed, the level is not a star and a half!"

"But... Isn't Xu Heng a Chinese teacher? When did he become so good at math?"

While talking, Zhang Ruiyun took out his mobile phone and took a picture of the subject.

"I have to first confirm how capable he is of this question!"

Ask a question, not just write it!

This requires sizing data verification!

Math problems, in particular, are much harder.

So every time the joint entrance examination, the most painful are those math teachers. They scratch their ears and scratch their cheeks and make repeated revisions. It takes a few days and they are not absolutely sure.

Ke Xu Heng wrote it so lightly!

ps: The eighth is more offered!

Thank you [Adult] for the monthly pass!

Ask for all support!

Ask for flowers, ask for evaluation tickets, ask for rewards, ask for comments!

Kneel thank you! .

9 Those who can answer this kind of question should participate in the college entrance examination! [9 more!Ask for a collection of flower evaluation tickets]

Zhang Ruiyun returned to the office and immediately took out a pen and paper to calculate.

"This second question involves an exponential function, which is quite difficult..."

I haven't touched math for a few years.

Even if he understood the knowledge points, he would not be able to start for a while.

"Forget it! Send it to my university group!"

Zhang Ruiyun University is a mathematics student. In his university group, the worst mixed person is also a mathematics teacher. Well, some university professors, mathematics research institutes, etc., are everywhere.

When Zhang Ruiyun's question came in, someone immediately bubbled up.

"Zhang Ruiyun, aren't you a math teacher? Why did you suddenly ask questions?"

"Is your child encountering a problem and won't come to ask you?"

"Is this question difficult?"

"Which year's college entrance examination finale question? No, I know the annual college entrance examination questions all over the country, but there is no such question..."

"Zhang Ruiyun, where did you get this question?"

"Can you help me introduce the person who asked this question?"

When the classmates in the group saw this question, they all seemed to be hungry. After asking the question in the group, they couldn't wait to chat privately.

Zhang Ruiyun, "Don't be so excited!"

"I mainly want to ask you guys about this question, how did it go? Is there any problem?"

Everyone in the group, "???"

"There's nothing wrong with this question! I looked at it in general and it's definitely a good question!"

"I'm already doing the second question!"

"This first question, that's it, the second question is the essence!"

"Yeah! Indeed, this second question does have the flavor of the finale of the college entrance examination!"

Zhang Ruiyun was speechless.

At this time, even Professor Chen Jianhua, who had been diving in the group, spoke.

As their math teacher when they were in school, Professor Chen Jianhua was obsessed with mathematics, and Qingbei always wanted to dig.

Although he is now in his 70s and retired, he is still very influential in mathematics.
