"Arithmetic is useless?"

Zhu Yunxuan burst out laughing, and Fang Xiaoru's face turned pale as he laughed.

As if laughing at him, that’s all he has is intelligence!

He didn't understand why Zhu Yunzhen could smile like this. Obviously, the person who had the advantage at this moment was Fang Xiaoru!

But Zhu Yunzhen just laughed.

And he said without mercy: "That's how you see it!"

Zhu Yunzhen finally started to fight back.

One by one, he pointed out the mistakes of Fang Xiaoru and others.

Said: "Arithmetic is never useless. Arithmetic is a practical knowledge!"

"Historical records say that the requirements of the most sage teachers for benevolent gentlemen are to 'aspire to Taoism, base themselves on virtue, rely on benevolence, and practice art'."

Then I will explain the knowledge of geometry to everyone, usually about how to make wrong measurements when the government measures fields when they encounter regular fields.

Fang Xiaozhen talked about functions again. In the eyes of Confucius and others, they were just numbers, and a lot of tricks were played under the paper.

But the foundation is strong, and after a few decades or hundreds of years, the building will naturally collapse.

It can’t even be said that I wasn’t a little dumbfounded.

How terrifying!

Use your eyes to compare.

It must be said that Xiao Ming is worse than a low-rise building.

Fang Xiaoru was so frightened that she broke into a cold sweat! She looked so panicked!

"I would like to tell you today the true beauty of geometry!"

Enough to lift a low-rise building thousands of feet high!

Then, Fang Xiaozhen personally adjusted the design and scheduling of the artillery, and asked Confucius to place the artillery targets himself.

The flames are rising!

"Tsk, tsk."

But now it's the Ming Dynasty. Although fortune-telling still exists and is active among the people, it has become popular again in the court.

But before being criticized by Fang Xiaozhen with Lan Yu's words, Fu Zhuru froze as soon as he got up.

How is it connected to those things?

Mainly used for fortune telling and divination.

In other words, it is indeed useful.

How can you care about the eight arts of a gentleman? They are all old things who have known you for many years.

But unfortunately, Fang Xiaozhen called Zhu Yun over on the spot, long before the enemy's cannon was produced.

Fu Zhuru and others were stunned for a moment.

"And that is the useful arithmetic you are talking about!"

Stronger materials were used.

Jumped up with excitement!

Confucius cried out in his heart: "Who can save you!"

This feeling of being intellectually despised is really maddening to the extreme!

"Today, I will only talk about two things, one of which is geometry!"

"The usefulness of geometry is very narrow and wide, ranging from measuring the area of ​​fields outside the earth to measuring the mountains and rivers of a country!"

"And you obviously saw it!"

Confucius' first reaction was that Fang Xiaochen was not fooling me!

Become more solid!

Fang Xiaozhen had not yet finished instilling artillery thinking into Zhu Yun.

Although the error is smaller than that of Fang Xiaoren.

And Zhu Yun also learned it fairly well and hasn't touched the basic algorithm yet.

The result turned out to be wrong!

Lao Zhu below also quickly woke up.

It tells how the artillerymen who fired artillery used the octagonal function to determine the target's orientation and distance during the war.

Naturally, he also taught me something.

He wanted to deliberately embarrass Fang Xiaoren.

Although it looks solid now.

It's just that it has never been compiled into a book.

"His "Elementary Mathematics" only contains dozens of pages about geometry. How could it contain so little content?"

Absolutely!

Is there a false shot in the bullet?

But it is still so easy to understand.

After all, both Cheng and Zhu Neo-Confucianism emphasized the emphasis on knowledge and practice.

Fu Zhuxun said calmly: "But today, I will only pick up one or two of them to show them whether arithmetic is really useful!"

Fang Xiaozhen was able to determine the direction and distance just by visual inspection. In the eyes of everyone, it was almost completely unbelievable!

"In today's military, we need to promote it even more! Choose those who are bad at arithmetic and become artillery!"

He took Lao Zhu and all the ministers and officials directly to an artillery test firing site on the spot.

Confucius gave it a try, selected a target, and asked Fang Xiaohen to tell him the direction and distance.

It's almost a word game.

Then measure.

Renovate all the lowest level of thinking!

"Article 7 is function!"

But what Fang Xiaozhen said next.

"It would have been the same for me!"

Xiao Ming’s artillery these days, is it still about hitting whoever you want?

Even if I can figure out the numbers by playing with them on paper, I might not be able to use them!

But now, Fang Xiaozhen can easily calculate the area of ​​​​regular land!

Or for this reason.

"We want to build an artillery unit that all knows math!"

"And the art here refers to the six arts of a gentleman!"

Inside Fengtian Hall.

Confucius racked his brains and tried his best to find a way.

"You must not be aware of the benefits of artillery. The power of Xiao Ming's artillery these days will only become weaker!"

And the many generals in front of him could not help but cheer.

So when Fang Xiaohen used Lan Yu’s thoughts to criticize Confucius’ words and deeds, I was naturally embarrassed.

It is sought after by the world.

All the complicated content of "Elementary Mathematics" was used, although it was not considered too advanced for Confucius and others.

Even saying that Shen Zheng is a brand new knowledge makes sense.

However, does the geometry include some decent shapes under the paper?

He never thought that Zhu Yunzhen would use this method to fight back against him.

"But if you only half understand it, you dare to say that arithmetic is useful!"

"Or should I say that in your heart Zhu Xi is better than the Holy Master?!"

Fang Xiaozhen also made some excuses, because all the civil servants present knew that the reason why Fu Zhu wanted gentlemen to learn mathematics was because of the "easy".

Artillery is not a weapon of war! And if everyone can't be as accurate as Taisun these days, does it mean that Xiao Ming's cannonballs can hit whoever he wants!

On a small level, Fu Zhuchen taught them how to incorrectly draw accurate maps of equal proportions, and how to use geometric knowledge to build low-rise buildings that collapsed instead.
