"Yes, I still insist. Mr. Qian, maybe we can find a solution. For example, you can give me some math problems you think, and let me do them. If I can do it right, you can give me the freedom not to have your class. How about that?" Zheng Hao looked at Qian Kaiyuan with sincerity on his face.

"Good! Now that you've said that, I'll have to help you. " Qian Kaiyuan frowned more tightly and said.

"Mr. Qian, why don't you have dinner first? After dinner, we'll make an appointment to finish what we just said." Zheng Hao said.

"No! I'm too impatient to wait! Now that we've talked about this, let's finish it Qian Kaiyuan said stubbornly.

"Well, let's ask Mr. Qian to make a question." Zheng Hao had no choice but to spread his hand.

He also saw the old man's stubborn nature.

To be honest, Zheng Hao was a little nervous at this time.

After all, Qian Kaiyuan is a well-known mathematician in China and has made a lot of contributions in the field of mathematics.

Can you really cope with such a mathematical problem?

Although Zheng Hao now has the skills of advanced mathematics specialization, he really has no idea what kind of position this advanced mathematics specialization is in the field of mathematics.

Qian Kaiyuan has a notebook and pen with him.

Maybe old scholars like him have the habit of writing down whatever inspiration they have with paper and pen.

Qian Kaiyuan looked at Zheng Hao's young, green and confident face. He said to himself, "this child is a genius. That's for sure.".

According to those reports, his mathematics level is very high, and he has been able to solve many difficult mathematical problems by completely self-study.

So, if you give him a question, naturally you still have to give him some really difficult questions, so that he can feel the complexity and profundity of mathematics, and calm his arrogant heart.

Qian Kaiyuan thought so, so he began to write a difficult problem of algebraic geometry in his book.

Algebraic geometry, that's the most difficult area of mathematics.

Even when students of mathematics department in famous universities encounter problems in algebra and geometry, it is almost the same as reading the book of heaven.

Generally speaking, algebra and geometry is not a required course for the Department of mathematics in universities. Only those students who have the spare time to learn can dare to challenge the crown of mathematics.

The problem of algebraic geometry written by Qian Kaiyuan is also the most difficult in the field of algebraic geometry.

After writing the title, Qian Kaiyuan handed his small book and pen to Zheng Hao: "what I give you is an algebraic geometry topic, which is quite difficult. Generally, only doctoral students in mathematics department can challenge such a topic! If you can solve this problem, I will admit that you have really learned mathematics well. "

Zheng Hao nodded: "OK, I'll try."

On one side, Li Yan heard it, but she started talking and whispered, "my God! It turns out to be a problem of algebraic geometry. "

"Yes, it's the problem of algebraic geometry. The difficulty of my problem is equivalent to the level of a PhD student in mathematics department. The average PhD student majoring in mathematics should be able to work out this problem easily."

Qian Kaiyuan nodded to Li Yan.

Li Yan said to Zheng Hao, "let me have a look at this problem."

She also has a competitive heart, want to see if she can do it.

"Well, you see first." Zheng Hao said with a smile.

Li Yan took this algebra geometry problem over and looked at it for a long time, and her brow wrinkled badly.

"Terrible, I can't see any way to solve the problem." Li Yan shook her head.

She took a worried look at Zheng Hao: "Zheng Hao, have you studied algebra and geometry before? Generally, this course is only accessible to students of mathematics department. "

Zheng Haoxin said that I am proficient in advanced mathematics skills, and I am naturally proficient in algebra and geometry.

"Yes, I taught myself. I have to admit, it's really hard." Zheng Hao said.

As he said this, he took his notebook and began to see the difficult problem of algebraic geometry.

He finished reading the question quickly.

Then, his brows were completely extended.

This problem is really a little bit difficult, but Zheng Hao just looked at it once and found out the way to solve it.

He began to calculate the problem quickly in Qian Kaiyuan's notebook.

There are many steps to solve this problem.

Zheng Hao finished six pieces of paper, and then he wrote out the final answer.

When Zheng Hao was working on the problem, Li Yan always stood beside Zheng Hao and watched him solve the problem.

She looked at it with a frown and a twinkle.

Li Yan's mathematics is also very powerful. She has learned some mathematics like algebra and geometry. Therefore, she can understand Zheng Hao's steps in solving problems.As she looked at it, she exclaimed, "my God! This child is really amazing. If he has a strong logical thinking ability, and the speed of calculation is very fast, he will be able to accurately calculate complicated calculations without using a computer at all. "

When Li Yan saw the end, she was relieved.

She knew that there was absolutely no problem for Zheng Hao to pass Qian Kaiyuan.

Qian Kaiyuan is naturally observing Zheng Hao.

Qian Kaiyuan naturally knows that this problem is not generally difficult. It's not only difficult to find the solution, but also the amount of calculation is too abnormal. If you want to work out smoothly, you need to list a lot of formulas. If you can borrow a computer, it will be much faster. However, if you count all by hand, it will take a long time to finish.

"The child looks very relaxed." Qian Kaiyuan's wife said beside him.

"If the calculation is easy, I think he must have miscalculated." Qian Kaiyuan said very firmly.

"Why do you say that?" My wife doesn't understand.

"Because of the huge amount of computation, even if you know the way to solve the problem, it's just a huge amount of computation that will make people shy away." Qian Kaiyuan said with a smile.

"Oh, that is to say, it takes a lot of energy just to calculate the steps." My old companion suddenly came to me.

"Yes, it took me three hours as a doctoral student to work out this problem." Qian Kaiyuan said with a smile.

"My God! Three hours! Shall we wait here for three hours, too? " How does Qian Kaiyuan's wife talk.

"Ha ha! We can eat slowly! I reckon that after a while, the child will find that he has gone astray, and then he will be lost. At that time, he will give up the problem himself. " Qian Kaiyuan said.

Although Qian Kaiyuan and his wife spoke in a low voice, Zheng Hao heard them clearly.

Zheng Hao heart smile, heart said, I think you will be disappointed.

Zheng Hao wrote down the final answer, and then said to Qian Kaiyuan, "Mr. Qian, I have finished this problem. Please have a look!"

Zheng Hao said and handed back the notebook to Qian Kaiyuan.

"What? It's over so soon? " Qian Kaiyuan was surprised.
