"It's more than that! If you use an abacus to preserve the process of calculating in such a vertical form, you won't be able to preserve it." Hong Lianshuo looked at him with a warm light in his dark jade-like eyes.

Upon hearing this, Cao Huaimin stood up excitedly, paced back and forth, and even jumped up and down like a child with joy.

"What's going on, Mr. Cao?" Facing the somewhat crazy Lin Nanzheng, he asked in fright and worry.

"Nothing is too happy." Hong Lianshuo looked at them with bright black eyes and smiled.

"What's so exciting about this?" Lin Nanzheng looked at her puzzled and asked.

"Arithmetic can be recorded like literature and passed down to future generations." Hong Lianshuo looked at them with his clear eyes and said.

"What's the point of arithmetic? It's rarely used on weekdays?" Lin Nanzheng raised his sword eyebrows and looked at her and said. It felt like it was too exaggerated! "Like when I collect food and grass, I only need to use numbers. I don't need it on weekdays."

"What do you know?" Cao Huaimin looked at him with a black face and scolded him angrily, "It can be as small as building a house or a city wall, or as big as the Great Wall. Without the support of arithmetic, what can you build?"

"I'm talking about ordinary people." Lin Nanzheng pursed his lips and defended in a low voice.

Cao Huaimin said regretfully, "Our arithmetic books only leave the results, but not the process. This is very difficult to learn."

"Many aspects of life are inseparable from arithmetic, and arithmetic can be said to be a basic subject." Hong Lianshuo looked at them with his dark pupils reflecting the dappled sunlight and said, "arithmetic expressions are really important."

Mathematics is the cornerstone of the development of science and technology! Natural subjects require extensive use of mathematical tools.

The use of mathematical expressions has greatly changed the way science and technology are accumulated, preventing many inheritances from being lost.

"This..." Lin Nanzheng scratched his head and said, "I can't feel it."

"Hey! Many of the Mohist arts and crafts have been lost. Why?" Hong Lianshuo looked at them with stern eyes and said, "This skilled craftsman has no way to express his wisdom and inventions. Due to the lack of concise and effective ways of expression, this skilled craftsman all uses

When a master leads an apprentice, he can only pass on his experience orally to spread and accumulate skills."

"So when you enter the palace, the first place you go to is the library, the Imperial Study Room." Lin Nanzheng looked at her with wide eyes and said.

"Yes! There is a golden house in the book. Since arithmetic cannot be recorded, this has caused serious faults in the New Dynasty." Hong Lianshuo said very discouraged, "You have read the book, and sometimes the writing is wrong! Don't say that.

Word of mouth is passed down by word of mouth, and a slight error can lead to thousands of miles. This chain of transmission is very fragile. How many apprentices can a master bring in his life, and how many of them can truly inherit the master's legacy."

"Aren't you afraid of teaching your disciples and starving the master to death?" Han Qinhu said after hearing this.

"Yes! The most terrifying thing is that there is a hand left, he saves a hand, he also saves a hand, and in the end everyone is gone." Hong Lianshuo looked at them helplessly and said, "Can't we strive for excellence? Can't we go further?"

"Just like the current war, the communication channels are cut off, and the technology is directly lost." Hong Lianshuo clasped his hands and said happily, "I am very grateful to Hu Bing for not burning down Yandu City with a fire." Although the library and the

The books in the imperial study were really pitiful compared to what she had read.

"Also, it is not conducive to technological innovation, because there are too few people who are qualified to understand this technology. It is equivalent to a secret technique and is almost not disclosed to the public." Hong Lianshuo tapped the branch in his hand on the ground.

, "With mature mathematical expressions, some techniques will no longer be esoteric."

"This is not easy to spread!" Lin Nanzheng looked at her hesitantly and said, "Copying is also very troublesome."

"It seems that Uncle Zhong not only wants to engrave characters, but also engrave figures and calculations..." Han Qinhu looked at them with a smile and said.

"What does it mean to capture a tiger?" Cao Huaimin looked up at him and asked.

"Print!" Han Qinhu looked at them with his light brown eyes and said, "We all have seals with our names engraved on them, which can be used to engrave articles! Bang bang bang..." He gestured with his hands, "You can print whatever you want.

, the font arrangements and combinations are ever-changing.”

"Oh my God." Cao Huaimin was so shocked that his eyes almost popped out of the window, "Now it can be printed into books, and it won't be a problem for everyone to have one."

"Yes!" Han Qinhu smiled and nodded.

"Did Madam Hong come up with this idea?" Cao Huaimin looked at Hong Lianshuo without blinking and guessed with certainty.

"How did Mr. Cao guess that?" Hong Lianshuo looked at him with interest and smiled.

"It's very simple! If you have the ability to catch a tiger, why would you bring it up now?" Cao Huaimin looked at her with joy and said.

"After the popularization of printing, everyone can see the calculation process. I can find out that I have a problem with that number. I will modify it on my basis and come up with a new formula, and then use printing to further improve it.

A new round of popularity." Hong Lianshuo looked at them in high spirits and said excitedly.

"What a breakthrough in arithmetic!" Lin Nanzheng looked at her puzzled and said.

"Of course, this cannot be faked at all, a ding is a ding, a mao is a mao." Hong Lianshuo looked at him with eyes as deep as jade and said, "The descendants have been making breakthroughs based on the unremitting efforts of their ancestors.

Progress can be made one step after another.”

"Why can't I feel it?" Lin Nanzheng looked at her doubtfully and said.

"How do you say it?" Hong Lianshuo lightly clasped his eyebrows with his index finger, "How can the arrows we usually shoot go the farthest? These can all be calculated."

"Ah!" Lin Nanzheng looked at her with wide eyes and said in disbelief, "How is this possible?"

"Isn't this archery so powerful that you can shoot far?" Chen Zhongyuan said simply looking at them.

"Then do you think the arrow that flew out shot far in a straight line or in an arc?" Hong Lianshuo looked at them with eyes full of interest and said.

"Isn't this arrow a straight line?" Jiang Shuisheng stretched out his hand and gestured, "Of course, if there is wind, it won't necessarily be true."

"What about you? Do you think so too?" Hong Lianshuo glanced at the others and asked.

"From what you say, Shui Sheng is wrong." Lin Nanzheng judged.

"Some arcs are the furthest." Cao Huaimin directly picked up a branch on the ground, poked a spot on the ground, and drew straight lines and arcs. "With different angles, arcs can be long or short."

"Ah! How is this possible?" Lin Nanzheng gestured with his hands, "Is it true?"

"This is amazing." Chen Zhongyuan looked at them with wide eyes and said.
