The Invincible Sixth Prince

Three acres?

Upon hearing this, Miaoyin also stared at the paper and started calculating silently.

It seems that it should be three acres!

Older children should be able to see it.

However, looking at Yun Zheng's expression, this answer was obviously wrong.

"Correct!"

Wu Dao said calmly: "The answer to this question can be seen at a glance."

Yun Zheng smiled and looked at Wu Qingyang again: "How did you find out that there was something wrong with this question?"

"I just wonder, Lord Zhang didn't say that the sum of plots A and B is the same size as plot C!"

Wu Qingyang stared at the paper and said, "Although they seem to be the same size, what you see is false after all! That's why I measured the land according to this. After measuring, I found something even more wrong..."

"Yes! That's the problem!"

Yun Zheng looked at Wu Qingyang approvingly and said, "How about this? Go pluck a long feather from a chicken or duck and give it to me. I have nothing to do now, so I'll show you how to count it on the spot!"

"well!"

Wu Qingyang was so happy that he ran to pluck the hair.

When he went to visit Zhang Huai, he heard Zhang Huai say that Yun Zheng liked to use a feather pen, and that feather pen was made by Yun Zheng.

"Your Majesty, do you really think this problem needs to be calculated?"

Wu Dao looked at Yun Zheng suspiciously.

"Of course!"

Yun Zheng smiled, "Mr. Wu, you should have heard that I like to make bets with people. How about we make a bet?"

bet?

Wu Dao's mind suddenly came alive.

The news of Yun Zheng's bet with Beihuan State Master in the imperial city had already spread throughout the world, so naturally he had heard about it.

However, I don’t think I’ve ever heard of Yun Zheng losing a bet!

"How does the prince want to bet?"

Wu Dao decided to first see what Yun Zheng wanted to bet on.

I heard that Yun Zheng is a sex addict. If he wants me to bet my niece, I will never agree.

"Mr. Wu, tell me what you want if you win!"

Yun Zheng stared at Wu Dao with a smile.

Wu Dao thought for a moment, then shook his head and said, "I don't know what I want either."

It doesn't depend on what he wants!

It depends on what Yun Zheng wants to give!

There are hundreds of Yun Zheng’s personal guards outside!

If Yun Zheng refuses to pay his debt, can he still eat Yun Zheng?

Yun Zheng thought for a moment and immediately said, "How about this, if I lose, I will give you fifty horses! If Old Wu loses, you can just give me your son this time!"

"Ok?"

Wu Dao was puzzled, "What does the prince want me to do?"

If Yun Zheng wanted Lan Hua, he could understand it.

But what does Yun Zheng want his son to do?

It's impossible that Yun Zheng still has that kind of habit, right?

Yun Zheng didn't know that Wu Dao had misunderstood, and said seriously: "I think Brother Wu is a talent, and he can be trained to study for the world in the future!"

Just for this one question, Wu Qingyang could stay awake at night thinking about it, which proves that Wu Qingyang is very interested in mathematics and is willing to spend time calculating these seemingly meaningless things.

In the Daqian Dynasty, such people are extremely rare.

After Wu Qingyang is trained well, he can be allowed to teach more people.

"This……"

Wu Dao hesitated, pondered for a moment, and replied: "If Your Majesty really wants to gamble, you can ask my son what he thinks. As long as he agrees, I have no objection! To be honest with Your Majesty, I also want to know what the mystery is in such a simple question!"

"Okay, it's a deal!"

Yun Zheng laughed.

If Wu Dao and his son could figure out the problem, then there must be something fishy going on!

However, Wu Qingyang's method is a good one.

Simple and straightforward.

“Is there anything mysterious about this question?”

Miaoyin asked Yun Zheng curiously.

Yun Zheng nodded and smiled, "It's more than just mysterious, it's extremely mysterious."

"Is it?"

Miaoyin also became interested. "Now that you mention it, I also want to know what the mystery of this question is!"

She understands Yun Zheng.

Since Yun Zheng dared to gamble, he must be sure of winning.

However, at least for now, she didn't find this question difficult.

Soon, Wu Qingyang came running over with ink and inkstone, and in his hand were two long feathers plucked from a chicken.

While Wu Qingyang was grinding ink, Wu Dao told him about the bet he had made with Yun Zheng.

Upon hearing this, Wu Qingyang fell silent.

"Don't worry, I don't want you to be my slave."

Seeing him hesitate, Yun Zheng said, "I feel that there are too few people interested in mathematics! But the usefulness of mathematics is far greater than those ornate articles!"

It’s also because Zhang Xu is not cut out for academic research.

Otherwise, he would definitely prefer to train Zhang Xu.

If you learn math, physics and chemistry well, you won’t be afraid to travel around the world!

I didn't learn chemistry well, so I haven't even made glass and TNT yet.

Wu Qingyang hesitated and looked up at his father again.

"What do you think I'm doing?"

Wu Dao glared at him and said, "You are already thirty-seven years old, make your own decision!"

Wu Qingyang thought for a moment again and made a decision in his heart.

"Okay! Then let's do as the prince wishes!"

Wu Qingyang's eyes gradually became firm, "It's my honor that the prince likes me!"

"Okay! Then I will start calculating!"

Yun Zheng said this and immediately started to write equations on paper.

He remembered that this seemed to be an elementary school math problem, and there was an easier solution, but he couldn't remember it at the moment, so he thought using an equation was the simplest and most direct way.

Looking at the equation that Yun Zheng had written on the paper, Wu Qingyang wanted to ask what it meant several times, but he didn't dare to interrupt him.

Yun Zheng’s calculation speed is very fast.

In less than a minute, Yun Zheng calculated the answer.

16/3.

According to Daqian's land area calculation method, it is about five acres and three centimeters.

"Yes, that's all!"

When Wu Qingyang saw Yun Zheng write down the specific acres of land, he immediately shouted excitedly.

"More than five acres?"

Miaoyin was surprised, "How come there are so many more?"

There is a world of difference between more than five acres and three acres!

"So, people should not be deceived by their own eyes."

Yun Zheng put down the feather pen in his hand and said, "The calculated result is the real result!"

“How can it be more than five acres?”

Wu Dao frowned and looked at the calculation paper in front of Yun Zheng with confusion.

Unfortunately, he couldn't understand the symbols and content on it at all.

"The fact is, it should be this much."

Yun Zheng smiled and said seriously: "When I was in the Imperial City, I taught Elder Zhang some simple algorithms, but to be honest, I didn't expect that Elder Zhang could learn so much at such an old age! There is a reason why Elder Zhang can become the Emperor's teacher!"

Listening to Yun Zheng's words, Wu Dao couldn't help but fall into deep thought.

What Yun Zheng meant was that Zhang Huai would keep learning until he died, but he, Wu Dao, only stuck to what he already had.

No matter how good the article is, it can never compare to Zhang Huai, the imperial tutor.

Although he understood Yun Zheng's meaning, Wu Dao did not argue with Yun Zheng. Instead, he asked with a puzzled look on his face: "How did the prince calculate this?"

Wu Qingyang also looked at Yun Zheng eagerly, obviously wanting to know what these things he listed meant.

Yun Zheng had nothing else to do, so he explained it to them in detail...
