Chapter 167

LAN Yin returned to the classroom and sat in her own position.

A few seconds later, Mr. Yu Zhen, who taught the class for the students, also entered the class.

Half a minute ago, Miss Yu Zhen was shocked by what she had just heard outside the door.

But in the class, she can also instantly restrain her emotions that she shouldn't have brought into the classroom as a teacher.

On the podium, teacher Yu Zhen opened the lesson preparation materials and took the students to class.

In the back of the classroom, LAN Yin is still not listening.

For mathematics, LAN Yin doesn't even need to turn the textbook after she has learned the problem-solving steps of complicating simple problems——

She put the math textbook in front of her and made a decoration. Then LAN Yin suddenly remembered what the math professor had just said.

He said that the world-class problem he solved was the problem of famous mathematicians in Europe?

As a native of China more than 100 years later, LAN Yin can't see that her country lags behind others in mathematics.

So she took out her mobile phone from the pocket of the gray and pink leisure suit she was wearing at school today. Under the cover of the textbook, her fingers "beat" on the mobile phone quickly.

Not long ago, she called up the mathematical problems left over by the world, which were displayed in the world's authoritative mathematical forum.

There were four questions, three of which were written by mathematicians in Europe, and one was written by a small country neighbouring China.

However, at first glance, this question is to follow the trend of drawing tigers, which is very similar to one of the three questions in Europe.

One of the three questions was written by European mathematicians more than ten years ago. From the question LAN Yin, we can see that this question is the most difficult of the three questions.

There are also two problems, which were solved by European mathematicians six years ago and one year ago.

The question six years ago was the simplest. LAN Yin took a look at the question type and got the answer two seconds later.

I think this is the problem that European mathematicians put forward a few years ago, just mentioned by Professor mu.

LAN Yin is still interested in solving problems.

Since we want to improve the status of mathematics in China, it is not enough just to solve a problem.

LAN Yin gently slides her finger and creates a new post in the post of this authoritative mathematics forum.

Then write down the solution process and answers of the three questions except the one solved by Professor mu.

At the end of the problem, LAN Yin did not forget to leave a new "difficult problem".

She wants to announce to the world that the most difficult problem in mathematics comes from China——

Of course, the difficulty of this problem is only relative to the three problems she solves at the moment.

In fact, in LAN Yin's view, it is still not difficult.

In her time, it was only the examination scope of junior middle school students.

But even so, even if the formula she left for Professor Mu was made public and wanted to solve the problem, it would be impossible to solve it in ten or eight years with the mathematical level of today's mathematicians.

At the end of the post, LAN Yin didn't forget to sign. She left a few words——

China.

——Blue.

While Lanyin solved three world-class mathematical problems and released them.

Professor Mulin, who temporarily borrowed from the president's office of Ningcheng No. 1 middle school, can't wait to release the problem he solved!

Not long after Professor Mullin sent it, he received much attention.

Even an honorary mathematician from the highest University in China found out his contact information and called him directly——

"Professor Mulin, I'm Yang Xian of Dida. I just saw the problem solving you released. Are you the blue? How did you solve those problems and what inspiration did you have?"
