Chapter 50

"What are the uses of mathematics?"

Mr. Mo was a little nervous when he had his first class. Fortunately, they were all acquaintances except Li Gaoming, which made him relax a lot.

"For the exam?" Chumo raises his hand and says a wise saying.

"Er, ER!" Merton said nothing.

"Settle accounts!" Zu Mingjun proposed a practical use.

"Accounting is really a great use of mathematics," Merton nodded.

"However, the use of mathematics is more than that. After learning mathematics, generals can calculate the speed of the army, the time of the battlefield, the food and grass needed, and even all kinds of situations of the enemy. How can such a general not win the war.

Those who do this can calculate the taxes and expenses of the state. They can also crack down on corrupt officials by checking accounts and govern the country reasonably. Ordinary people can calculate accounts and record family expenses. Even street vendors have to learn arithmetic without a teacher. Arithmetic runs through everyone. "

"We are dealing with arithmetic all the time. Arithmetic is very important. I like arithmetic more than any subject! Today I want to call you not only arithmetic, but the spirit of arithmetic.

In mathematics, every number is fixed, and no change is allowed. One plus one equals two, not three, not any number. Mathematics is such a cold number. It tells you the naked truth. You can't believe anyone or anything in the world, but please believe in mathematics. Anyone in this world can cheat You, but only arithmetic can't. when you learn arithmetic, you control the right to insight into the truth. "

Merton's words made everyone think, especially Li Gaoming, whose eyes were shining,.

Even Qin Huaiyu, who was going to make soy sauce, couldn't help sitting up straight and listening carefully.

"Mohist's arithmetic is different from the ten classics of arithmetic you usually learn! The basis of everything is these ten numbers, zero one two three four five six seven eight nine, these ten numbers."

Merton took a charcoal pencil cut from charcoal and wrote the ten numbers on a board.

Looking at the black ash in his hand, Merton secretly determined to get the chalk out quickly. After all, the process is very simple.

"We've all learned this!" Wei Chi Baolin wondered.

"Really?" Merton smiled. "What about these ten numbers?"

Merton wrote under the blackboard: "0123456789."

"This is also a number? It can't be a ghost symbol!" everyone was confused by the crooked Arabic numerals.

"Merton, you won't learn witchcraft! It's a ghost amulet!" Qin Huaiyu said with a smile.

"It's a number, but it's a number from India?" Li Gaoming said suddenly.

Merton took an unexpected look at Li Gaoming. Unexpectedly, he knew that these numbers were indeed Tianzhu numbers. However, they were later spread around the world by Arab businessmen before they were honored as Arab numbers.

"This is indeed the figure of Tianzhu. Brother Gao Ming is so knowledgeable. This is the essence of mathematics learned by Mohists who have gone to Tianzhu for thousands of years!" Merton shamelessly put gold on Mohists' face.

Merton then wrote several groups of numbers in Chinese characters on the blackboard, and wrote the meaning of representation in numbers. All the five present have a certain mathematical foundation and can easily understand it.

I don't know. Arabic numerals have obvious advantages in large-scale computing, and they are easy to learn and clear at a glance.

"It's too convenient?" Qin Huaiyu was very interested. If arithmetic were like this, he would have learned it long ago.

"The Mohist ancestors are really admirable. I heard that an eminent monk named Xuan Zang made a great wish a few years ago to go to Tianzhu to ask for the Scriptures. I didn't expect that the Mohist ancestors had already asked for the scriptures of mathematics from Tianzhu." Zu Mingjun was surprised.

"Uh, uh!"

Merton was a little blushing no matter how thick skinned he was. He hesitated and acquiesced. He said sorry to Xuanzang in his heart and shared the aura of your Westward Journey to learn scriptures.

Merton simply taught five people addition and subtraction? It makes five people exclaim constantly. Compared with the calculation in the Sutra, it is simply too convenient.

Zu Mingjun is infatuated with calculation.

"That's all for today's class." Merton breathed a sigh of relief and interrupted the five people's reluctant practice to end today's class.

Several people reluctantly put down their quill pen. They found that writing Tianzhu numbers with quill pen is much simpler and faster. They can't write well with quill pen. They have changed to quill pen one after another, which is the first expansion of quill pen!

"Brother Mo has a broad mind. I'm very grateful for giving you the secrets of Mohist arithmetic." Li Gaoming sincerely admires him.

Zu Mingjun also thanked him. In contrast, the Mohist School's arithmetic is much better than that handed down by his ancestors. Just a Tianzhu number has made Zu Mingjun unable to compete.

"No, no!" Morton said modestly.

After all, the six were teenagers. They didn't have so many rules. They soon became one and had a good time.

Unconsciously, it was time for dinner. Merton said to leave Zu Mingjun and Li Gaoming for dinner. As for Qin Huaiyu, they are evil guests who can't be driven away.

"That's disrespectful! I've heard that brother Mo invented steamed stuffed buns. The food of Mohism must be unique." Li Gaoming said calmly.

"Then you'll have a blessing in the mouth. My uncle Yu arrived today. He's a great fish maker. It's said that even his majesty praised his cooking in the army." Merton said.

"Oh! Then we'll have a good taste," Li Gaoming said with a smile.

Since Li Gaoming had promised to stay, Zu Mingjun was not modest and stayed.

"Here comes the fish!" the fish master took the prepared fish to the table, a pickled fish, a braised fish, a steamed fish, and several small dishes. In front of each person, there was a bowl of delicious rice, but three of them were huge, which was obviously reserved for Qin Huaiyu.

"Take your time, young masters!"

After Master Yu left, Merton pulled a backrest chair specially made for him by Lao Zhang tou and asked several people to sit down. The table is still a unique round table in Mojia village, regardless of primary and secondary positions.

"This table and chair is also unique!" Li Gaoming looked at the round table and leaned back against the chair. He found that the chair could just hold his waist, which was very comfortable.

"Mohism has no rules. How can you be comfortable?" Merton was very uncomfortable with the habit of kneeling and eating in the Tang Dynasty. He had no way outside. In the Mohist house, he changed all tables and chairs. Anyway, he didn't seem very strange under the pretext of Mohism.

As the master, Merton was the first to move his chopsticks, pick up a piece of fish and start.
