Fake daughter, she is beautiful and sassy

Chapter 168
Lan Yin returned to the classroom and sat in her seat.

A few seconds later, teacher Yu Zhen who taught the class for the students also walked into the class.

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

But when she was in the class, she could also instantly restrain the emotions that she should not bring into the classroom as a teacher.

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

But in the back row of the classroom, Lan Yin was still not listening.

For mathematics, after learning the steps of solving simple problems to complicate them, Lan Yin doesn't even need to turn over the textbooks——

She put the math textbook in front of her as a display, and then Lan Yin suddenly remembered what the math professor said just now.

He said that the world-class problem he solved was a problem posed by a famous European mathematician?

As a native of China more than 100 years later, Lan Yin could not see that her country lagged behind others in mathematics.

So she took out her mobile phone from the pocket of the gray-pink casual suit she wore to school today, and under the cover of the textbook, her fingers 'jumped' on the mobile phone quickly.

Not long after, she called out the mathematical problems left over from the world today, which were displayed in the world's authoritative mathematics forum.

There were four questions in total, three of which were posed by European mathematicians, and one question was posed by a small country neighboring China.

But at first glance, this question looks like a tiger following the trend, and it is very similar to one of the three questions in Europe.

Among the three questions, one of them was posed by European mathematicians more than ten years ago. From the title, Lan Yin can tell that this question is the most difficult of the three.

There are two other questions that were posed by European mathematicians six years ago and one year ago.

Among them, the question six years ago was the easiest. Lan Yin glanced at the question type and came up with the answer after two seconds.

I want to come to the question that Professor Mu mentioned just now that European mathematicians posed a few years ago, it is this one.

Lan Yin is still somewhat interested in solving problems.

Since Huaguo's mathematics status is to be improved, it is not enough to just solve a problem.

Lan Yin swipe her finger lightly to create a new post among the posts on this authoritative mathematics forum.

Then write down the problem-solving process and answers of the three questions except the one that Professor Mu solved.

At the end of solving the problem, Lan Yin did not forget to leave a new 'difficulty'.

She wants to announce to the world that in mathematics, the most difficult subject comes from Huaguo——

Of course, the difficulty of this question is only relative to the three questions she has solved at the moment.

In fact, from Lan Yin's point of view, there is still no difficulty.

In her time, it was only the examination scope for junior high school students.

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

At the end of the post, Lan Yin didn't forget to sign it, she left a few words——

China.

--blue.

At the same time that Lan Yin solved three world-class math problems and released them.

Professor Mu Lin, who temporarily borrowed the principal's office of Ningcheng No. [-] Middle School, couldn't wait to publish the question he solved!

Not long after Professor Mullin sent it out, he received a lot of attention.

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

"Professor Mu Lin, I'm Yang Xian from Imperial University. I just saw the solutions you posted. Are you that Lan? How did you solve those problems? What inspiration do you have?"
