Chapter One Thousand Seven Hundred and Sixty-Nine Unsolvable
When Zhu Yunye arrived, Han Jingyun was building flowers and trees with a pair of silver scissors.
Hearing Zhu Yunye's arrival, Han Jingyun put down the scissors in his hand and stood up. He looked at his son striding forward with a smile and said with a smile, "Emperor, why are you free to come to my place today?"
Han Jingyun put the scissors back into the plate held by the maid aside, took out a wet wipe and wiped his hands carefully.
Zhu Yunye smiled and helped his mother to sit down, and said, "Don't you miss your mother, so I came over quickly."
Han Jingyun glanced at Zhu Yunye and said with a smile, "The world is so big, how many things need the emperor to deal with every day?"
After shaking his head, Han Jingyun advised, "I told you a long time ago that you don't have to come over to see me all the time. As long as you govern the world well and can be worthy of your father, that's all."
Although Zhu Yunye is busy, he will come to visit her every few days. And although this time may be long or short, the longest will not exceed five days.
Zhu Yunye replied softly, "Aren't you worried that your mother will be lonely?"
After taking the throne, Zhu Yunye soon discovered that his mother had become taciturn. At first, he thought that his mother was dissatisfied with him for forcing Lord Zhen to go to sea. Later, he slowly discovered that his mother was missing his father.
Only then did he realize that while his excitement about ascending the throne had overtaken his longing for his father, his mother could only fall into longing for her father.
From then on, he would come to visit his mother whenever he had free time.
Han Jingyun was of course very happy that Zhu Yunye came to see her, but he still warned, "The emperor still has to put state affairs first. My place is very good, so you don't have to worry about anything."
Zhu Yunye nodded in agreement.
After a pause, Han Jingyun saw that Zhu Yunye was hesitant to speak, so he asked, "What? Did something happen to the emperor today?"
Zhu Yunye shook his head first, then nodded again, and said with a smile, "It's not something important. I just encountered a mathematical problem. I thought about it for a long time and couldn't figure it out, so I wanted to ask my mother for help."
"Oh? Are you still studying mathematics now?" Han Jingyun looked into Zhu Yunye's eyes with a smile, and the playful look in his eyes made Zhu Yunye avoid it in embarrassment.
With Han Jingyun as his mother, Zhu Yunye of course studied mathematics hard under her encouragement. But after he became emperor, he put mathematics aside.
Firstly, he does not have a high talent for mathematics, and it is difficult to achieve any results if he continues to study. Secondly, it will take a lot of time for him. Being an emperor has to deal with a lot of government affairs, and time is already very tight.
If you study mathematics, you won't have enough time.
This is also the reason why Han Jingyun has never asked him to learn mathematics since Zhu Yunye came to the throne.
Of course Han Jingyun would be surprised to suddenly delve into mathematics now. But she still clearly remembered how painful it was when Zhu Yunye was learning mathematics.
Zhu Yunye laughed twice and quickly explained, "It's not that I studied it, it's"
Yu Qian announced the topic and made bold remarks, and briefly discussed it with his mother.
"Oh~" Han Jingyun understood immediately, "It turns out to be Yu Qian. His math is pretty good."
Hearing his mother's comments about Qian, Zhu Yunye felt a little jealous. You know
He said that he and his mother had studied mathematics for so many years, but they had never heard her say anything good.
Zhu Yunye shook his head slightly, put the idea aside, and asked with a low smile, "Mother, is Yu Qian's question difficult? Otherwise, how can he be sure that no one can solve it?"
Han Jingyun looked at his son with bright eyes and said with a smile, "Haven't you already tried it? Is it difficult? You don't know?"
Zhu Yunye smiled awkwardly, "I knew I couldn't hide it from my mother."
Soon Zhu Yunye's expression returned to normal, and he asked curiously, "Mother, this question seems quite simple, but when I tried to solve it, I found that it was not ordinary difficult. What's going on?"
Han Jingyun took a sip of ginseng tea and slowly explained to him, "The difficulty of math questions has nothing to do with the complexity of the questions. There are quite a few simple but very difficult questions."
"This question is to draw a regular heptadagon using only a ruler and compass. In fact, it is a disguised form of dividing the circumference of a circle into seventeen equal parts. This is very difficult."
"Yes, do we need to use circles?" Zhu Yunye was stunned. Without the reminder from his mother, he would not have even thought of taking this step.
Han Jingyun suddenly became angry and scolded, "You haven't even thought about the need for circles to make basic drawings, and you want to draw them out?"
Zhu Yunye immediately smiled awkwardly and muttered in a low voice, "Er Chen, please tell me directly, how to solve this problem?"
Han Jingyun shook his head slightly and said nothing.
Zhu Yunye suddenly opened his eyes in surprise and asked, "Isn't it possible that even the Queen Mother can't do anything?"
Han Jingyun reached out and patted Zhu Yunye's head and shouted, "This question is not as simple as you think. Even if I want to solve it, I still need to calm down and think about it. Moreover, it may not be possible to solve it."
"Just now, didn't Queen Mother see the key to this question at a glance?" Zhu Yunye said in a low voice, not daring to talk back.
Han Jingyun gave him a strange look and asked, "Why are you so persistent in trying to solve this problem? Do you still want to get a reward from the Institute of Mathematics?"
Hey, Han Jingyun took a deep look at his son and guessed, "You don't want me to figure it out and then announce it, do you?"
"No, no" Zhu Yunye waved his hands repeatedly and said with a smile, "Why would I care about the reward from the Institute of Mathematics? I just, just"
Han Jingyun immediately understood that his son wanted to use it to show off.
Shaking his head at him speechlessly, Han Jingyun said, "You don't have to think about it. Even I am not sure that I can solve this problem in a short time. There are only ten days before the deadline of the academy, so it's too late."
Zhu Yunye's face was filled with disappointment and he said angrily, "How could Yu Qian say such bold words? It turns out that there was no time at all."
Even the mother of the world's best mathematician is not sure that she can solve it in just ten days, so naturally others can't even think about it.
Yu Qian is young, but he is as cunning as his master.
Han Jingyun smiled and shook his head, saying, "No matter what Yu Qian does, as long as he can really solve this problem, then he deserves the reward."
After Zhu Yunye heard this, he had to nod his head in agreement. After all, the difficulty of a question that even his mother felt could not be solved at once was conceivable. When Zhu Yunye came, Han Jingyun was building flowers and trees with a pair of silver scissors.
Hearing Zhu Yunye's arrival, Han Jingyun put down the scissors in his hand and stood up. He looked at his son striding forward with a smile and said with a smile, "Emperor, why are you free to come to my place today?"
