Spring and Autumn I Am King

In terms of archery, Wang Sunqi watched Wu Xie shoot a few pots of arrows, and after the arrows hit the bullseye, he said without changing his face that his skills were not as good as others, and asked a gentleman to learn by himself.

He also taught a sincere and sincere lesson: "However, archery does not represent the path of the arrow. The heart is straight and the arrow is straight. The heart of a gentleman is like a scorpion, and its straightness is like an arrow."

Although he didn't understand it well, he looked very powerful, so Zhao Wuxi had to do what he should.

…

The teacher of Shu and Shu was the chief planner of the lower palace, named Ji Qiao. "Counter" is a position passed down from generation to generation in their family, and gradually it became a family name. The accountant was specifically responsible for auditing various accounts. It was later called the master book, which was equivalent to a financial accountant.

Zhao Wuxi remembered that there was also an economist Ji Ran who inherited Guan Zhong's teachings in this era. He should not have been used by Goujian, the king of Yue who had just succeeded to the throne, and he didn't know where he was.

In addition, Ji Qiao's handwriting of Jin State seal characters is also quite beautiful, but Zhao Wuxi cannot recognize many characters.

Moreover, Zhao Wuxi discovered another thing. At this time, the brush has been widely used. Therefore, what the brush was invented by Meng Tian of the Qin Dynasty was a brain supplement for later generations.

On this day, after Ji Qiao reviewed the seal characters Wu Xie wrote on the bamboo and slips, his short beard cheeks twitched slightly.

Because it's so horrific! What the **** is this lump? This is also the reason why Wu Xie escaped all the calligraphy lessons that his parents paid to force him to attend in his previous life, so he was almost on a zero basis, and the characters he wrote were often mixed with some strange things...such as simplified Chinese characters in later generations.

So Wu Shi was watched by Ji Qiao every day to practice Jin Zhuan, copying "Poems" and "Shangshu". Writing on bamboo slips is not easy. From time to time, it has to be scraped and rewritten with a copper scraper. The efficiency is surprisingly slow. This painful experience also prompted him to consider whether to find an opportunity to invent paper?

And with paper, at least you can get rid of the horrible toilet chips when you go to the toilet. Some toilet chips are still public... This is a foolish ancient life.

When he was practicing calligraphy, Wu Xia was abused by Ji Qiao like a primary school dog who was punished for copying Chinese textbooks in his previous life, but when he learned to measure and count, the situation was reversed, and he was finally able to raise his eyebrows!

"Sir, it's not that the kid is lazy, it's that this trick is too slow and troublesome, and it's not very useful."

Ji Qiao is an outstanding mathematician. He became famous in the Zhao family's palace at a young age. Zhao Wuxie said that he was not willing to learn. Of course he was not happy.

"Numerical science is one of the six arts of a gentleman, and it is the only magic weapon to secure one's life. In the future, if a little gentleman arrives at a fief, if he can't even calculate taxes and taxes, it is difficult to guarantee that he will not be deceived by Zaoli and the big clan. Brigade Commander, if you don't know math, you can't measure the height of a mountain slope, you can't measure the depth of a river, you don't know how to coordinate the shipment of corn, and you're not good at scheduling the number of divisions and brigades!"

This Spring and Autumn mathematician is simply heartbroken.

This era is no better than later generations. Mathematics has a very important position, and it is not a sideshow. Otherwise, it would not be listed as one of the six arts of the gentleman. If a scholar wants to be a retainer, he must first pass the test of arithmetic.

Mathematical subjects in the Pre-Qin and Han Dynasties are mainly divided into nine types: Fangtian, Shumi, Decline, Shaoguang, Shang Gong, Equal Loss, Insufficient Profit, Equation, and Pythagorean, many of which are extremely practical. However, Ji Qiao was also very interested in the pure arithmetic of metaphysics, and even became an obsessive mathematician.

"Sir, the boy knows that mathematics is very important. People stand in the world. It is really inseparable from this knowledge everywhere. It is even more useful than those vulgar manners, but it is worth it..."

Zhao Wuxi looked at the densely packed table of calculations, and the intense phobia suddenly broke out, and he felt a little dizzy...

Suanchou is actually a small stick of the same length and thickness, mostly made of bamboo, but also made of wood, animal bones, ivory, metal and other materials. About two hundred and seventy pieces are in a bundle, put in a cloth bag, tied around Ji Qiao's waist and carried around. When you need to count and calculate, take them out and play with them on the table or on the floor.

As far as counting is concerned, the larger the number to be counted, the larger the area to be counted, and the large numbers are multiplied together. Ji Qiao is obviously a master at calculating. He divides the numbers into groups for calculation. He is quick-witted and has a superb memory. He just laid out a calculation array on half of the table.

Zhao Wuxi asked himself if he couldn't do it, but he also had his own tricks.

A lot of knowledge in his previous life has been returned to the teacher. In college, he was a mess in high school, but he couldn't play complicated things such as calculus. He still had the basics of junior high school and high school, and he could use it to fool people.

What, are you saying that you can pretend to use a multiplication table in elementary school? However, I'm sorry, Zhao Wuxi is sad... It should be a gratifying discovery, this thing has been formed since the Western Zhou Dynasty.

Although, the order is reversed from that of later generations, the multiplication table of Ji Qiaojiao starts from "nine nine eighty one" and ends with "two halves are one".

In addition, the Pythagorean theorem has also been discovered in the ancient calculation scriptures of the Zhou people, and there is also a great master who did not leave a name who listed the formula for the height of the sun...

"The little gentleman's words are a bit ridiculous. You don't need to calculate, how to calculate it? It's like crossing a big river without a boat, and fighting at close quarters without a fight." Ji Qiao has a headache. It is rumored that this little gentleman behaves perversely and does not talk about etiquette. It's hard to teach, it's true.

"The boy does know a method, which is very different from the method that Mr. uses a tool to calculate. Mr. can ask a question and let me demonstrate it."

Ji Qiao decided that he had to surrender to this contemptuous gentleman who was full of nonsense.

"Alright, then I'll take the test of the little gentleman, so that you know the breadth and depth of mathematics, and you can't handle it casually."

Ji Qiao disapproved of Wu Xian's remarks in his heart, and he simply asked a difficult question.

"Today, there are savages renting and hiring a gentleman's farmland. UUkanshu www.uukanshu.com rents out 1 mu per mu in the first year, 1 mu in the next year, and 1 mu in the next year, for a total of 100 yuan in three years. Money, how much is the rented land?"

This is exactly what he demonstrated just now with his calculus. With his ability, he has been fiddling with the table for a long time. Just now, Zhao Wuxi didn't listen carefully at all, so he probably couldn't answer.

Zhao Wuxi smiled slightly, and sure enough, he didn't go to get the money, but picked up a thin bamboo stick and started writing and drawing on the sand table indoors.

Using arithmetic can be a little troublesome, but Arabic numerals and arithmetic are much easier.

Ji Qiao was surprised to find that Zhao Wuxi really didn't need to do calculations, and although he had never seen the vertical formula listed on the ground, based on his years of arithmetic experience, he found that it was extremely simple and quite reasonable.

He had never heard of those strange, twisting and twisting symbols in the vertical form, such as 0123. Besides, what did the "one" mean? What about "ten"? What the **** is this cross lying down diagonally?

The idiot Jiqiao scratched his ears and scratched his cheeks, and he was fascinated by it, but before he could figure out a way, Zhao Wuxi actually solved the problem!

Although the vertical method used by Zhao Wuxi was only the most basic arithmetic in elementary school curriculum in the 21st century, in the Spring and Autumn Period of the fifth century BC, it was definitely an advanced scientific method that surpassed the times.

After finishing the matter, he clapped his hands easily and said, "Sir, the boy knows the answer. A total of 27 acres is rented out, 31 of 47 percent of acres."

Ask for collection, ask for recommendation...
