Chapter 4 Figures

"Oh, that's good. But there are new discoveries. "During the period when the eldest grandson was in school, Dr. Zhao did not drink the eldest grandson to discuss the problem of arithmetic. In view of the actual situation of ancient Chinese mathematics, most of the discussions are about multivariate equations and right triangles, and others are relatively rare.

"That's right, the student experienced such an incident in a village in the vast Qinling Mountains at this time last year, I wanted to buy eggs from a peasant woman, but she didn't sell them, she planned to exchange eggs for salt, I told her that the money could buy eggs, but she just shook her head, because she couldn't count the eggs and money, so I exchanged eggs with her for a penny." The eldest grandson finished telling this story in one go, which was the reason he had already thought of.

"And then?" Dr. Zhao is undoubtedly a qualified audience, and it seems that this emotional intelligence is also scored, but this Li Chunfeng is a little inexplicable.

"After the change, I wondered if I could use a simple way to keep them literate." This is what Changsun Tang has experimented with.

"Got a idea?" Dr. Zhao's obsession with arithmetic is evident.

"I thought of it, it's like this, the number is a group of ten numbers, I call this the base ......," Changsun Tang explained in detail about the Arabic numerals and how to use them.

Halfway through, the three of them moved to Dr. Zhao's study, writing Arabic numerals with a brush, which made Changsun Tang very weird, and this may also be a combination of Chinese and Western.

As the explanation deepened, Li Chunfeng's expression slowly became more and more serious.

It is true that Li Chunfeng is a god stick, but the ancient god sticks, especially the god sticks with official positions, are arithmetic masters and astronomers, because the most important thing these gods need to do is to guess the auspicious days of the zodiac and formulate a calendar. Therefore, China's arithmetic achievements and astronomical observations in ancient times have always been far ahead.

Therefore, Li Chunfeng is still a very famous mathematician, at least a mathematics educator.

As the so-called connoisseur knows if there is one as soon as he makes a move, this Li Chunfeng is still very knowledgeable, and when he is about thirty years old, he is also the age when both liquid intelligence and crystal intelligence are emphasized, and his energy and reaction speed are not slow.

While Dr. Zhao was still reminiscing, Li Chunfeng had basically mastered the use of Arabic numerals.

The eldest grandson had to sigh that the existence of this scholar is for comparison.

As a chronicler who assumed part of the secretarial duties when Li Shimin joined the army, Li Chunfeng has deep trust in Li Shimin, coupled with the professionalism of his official position, so he has somewhat developed Li Chunfeng's arrogant temperament.

But tsundere people are also the easiest to persuade, once you defeat him from his strongest, his tsundere will be crushed. Of course, as a god, his mind is also relatively strong, and he will have the idea of admiring Changsun Tang, but he will not show it easily.

Before I knew it, I didn't know where I had gone at this time.

It was already late afternoon, and the eldest grandson and Li Chunfeng said goodbye.

The eldest grandson plans to take a look at his own industries, which are related to the success or failure of his future plans, so he has to be cautious.

And Li Chunfeng rushed towards the palace.

When this Li Chunfeng passed through the city gate, the waist card lit up, and the flying horse was just a routine search and then released, it seems that this Li Chunfeng is deeply trusted by His Majesty Li Er.

After passing through the layers of transmission, Li Chunfeng met His Majesty Li Er, who was reviewing the recital in the Ganlu Palace.

"Meet Your Majesty." Li Chunfeng bowed down even if he saluted, and at this time, he needed to bow down to the emperor when he went out of the court, and there was no need to kneel the rest of the time. This kneeling ceremony was prevalent in the Qing Dynasty, bending the knees, breaking the spine, and showing servility.

"No courtesy." His Majesty didn't raise his head, obviously the relationship between Li Chunfeng and Li Shimin is very good.

The relationship between Li Shimin and Li Chunfeng is not only from the relationship between the upper and lower levels during the Qin Dynasty, but also involves the relationship between the Daomen and the Li Tang ruling class.

As the Li family with Hu blood, it has not been treated well by the Han people, and the "Clan Chronicles" ranks the surname Li in the third visible general, so the Li family emperors of the past dynasties basically believe in Taoism, and also found an ancestor for themselves - Laozi Li Er.

This Li Tang and Daomen belong to the relationship of mutual use.

Of course, in China, the government is above the faith, unlike Western Christianity, which can determine the emperor, which also leads to the confusion of faith in this part of China.

"Is there something important?" Li Shimin put down the piece at hand and rubbed his somewhat sore head.

Li Chunfeng first reported on some recent revisions to the calendar.

"Is there anything else?"

"It's not a big deal, it's just that I met an interesting person and wanted to ask His Majesty to come over."

"Oh, this is new, you have always admired the above-the-top character." Li Shimin made the situation at a glance.

"Ahem." Li Chunfeng was choked.

"Hehe, let's hear it." Li Chunfeng was rarely deflated, which made His Majesty Li Er, who was full of gossip, very curious.

"His name is the eldest grandson ......"

Hearing the name again, Li Shimin picked up the tea, and saw the tea leaves rising and falling in the water but put it down.

"Tell me, what do you want him to do?" Li Shimin still spoke.

"That's the ......," Li Chunfeng said urgently, saying the performance of the eldest Sun Tang in Dr. Zhao's study this morning.

"Do you have to?" Li Shimin asked expressionlessly.

"It's not, it's just that this eldest grandson has a lot of attainments in arithmetic, and it is more important for the Taishi Bureau to revise the calendar." Although Li Chunfeng is a god stick, he also knows some psychological knowledge, but after all, he is facing the emperor, and his heart can't help but be a little turbulent. Originally, if it was someone else, he would have been able to go to the Ministry of Officials to ask for someone, and this eldest grandson Tang was the son of the eldest grandson Wuji, so this matter was not easy to handle, so he brought it up from the beginning by revising the calendar report.

Li Chunfeng did not receive an answer, and this was not a big deal for him. After the report, he returned to his Taoist temple, but Li Chunfeng lived in the Taoist temple.

Not long after Li Chunfeng left, Li Er felt a headache again.

Every time at this time, Empress Changsun would come in with boiled porridge, and listen to Li Er's complaints while rubbing it.

This time I didn't hear any complaints, but only a familiar name.

"Eldest grandson, eldest grandson ......"

"What happened to the sixth son of this big brother's family?" At other times, the eldest grandson would not interject, but the eldest grandson's family is his maiden family after all.

"Hey, how can he be everywhere, Qinling cracked down on a bandit, he forced a guy who killed people and sold goods to surrender, and he could make such a tea when he was blocked on the road, and his classmates didn't have salt to sell pickles every day, and they also had one or two dishes and nine taels of salt."

The eldest grandson queen couldn't help but laugh when she heard it.

"This is not over, there is a plague, Sun Daochang said that he can prevent it; disaster relief, this Wang Jue said that he had a way; Even Li Chunfeng said that he had a high level of arithmetic. I really want to dig out his heart and see how it grows. ”

"That's not good, he can call me aunt, I won't do it if you dig out his heart." Empress Eldest Sun also rarely accosted Li Shimin when he was dealing with official business.
