Thinking carefully about what happened just now, even Ruyi knew the routine, which made Li Yi, who thought she knew her very well, feel tired. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

Fortunately, I still stuck to the bottom line just now, and I was not confused by the bait she thrown, if I was careless just now, I exposed the careful thinking in my heart as a man, I don't know what the ending will be?

I don't know, the current Ruyi, even he can't guess it.

The person who came from the palace was still a eunuch, but he was not known to Li Yi, standing straight in the front hall, with a straight face, seeing Li Yi walking in from the outside, he stepped forward and said in an emotionless voice: "Your Majesty has issued an order to let Li Xianzi teach the arithmetic of all the princes and princesses, and now the doctor of arithmetic of Guozi is on leave due to illness, in order not to delay the schoolwork of the princes and princesses, Li Xianzi will follow me into the palace now." ”

"Now?" Li Yi frowned, he was in such a hurry, and he didn't let people slow down, he was preparing for class or something, he didn't even have any preparation, what did he talk about when he entered the palace?

The eunuch made a straight face and urged: "Your Highness's homework can't be delayed, Li Xianzi should hurry up." ”

"Got it, got it, you wait, I'll be out right away." Li Yi waved his hand, turned back and said a few words to Ruyi, and soon walked out, looked at the eunuch and said lightly: "Let's go." ”

A carriage had already been parked outside the door, and with the distance from the palace from here, it was enough to take a carriage for half an hour.

The age of a group of little princesses and little princes is about seven to ten years old, if it is in the later life, the normal level of mathematics is also the second or third grade of primary school, but considering that they have never taken a mathematics class, and they don't know what the previous arithmetic class was like, Li Yi decided to start teaching from the most basic.

Of course, textbooks are not a problem, from kindergarten classes to university textbooks, there are a complete range of textbooks, and the textbooks of later generations are professionally certified.

At the gate of the palace, the waist card was shown, and the eunuch walked in, the last time he came out of the palace, Li Yi remembered some roads, the place where the princes and princesses went to school was in the Bowen Palace, and they would pass by the Shangshi Bureau on the way, and the distance between the two was not far.

When he walked to the door of the Bowen Palace, the eunuch said a word, and stood outside the hall and waited, "Li Xianzi, there is still a quarter of an hour that is the time for the princesses and princes to calculate their homework, you go in first." ”

Bowen Hall is a small palace, when Li Yi walked into the hall, he saw a low table and a low table in the hall, it may be that the time has not come, there is no ------ in the hall, only a fat man sleeping on the table in front of him.

Judging from the back, the little fat man and Ying Li Yingcai are about the same age, and in terms of body size, they are slightly inferior to him, lying on the table and falling asleep, and making a slight snoring sound.

Perhaps it was Li Yi's footsteps that woke him up, and the little fat man bounced up from his position and said loudly: "Disciple rules, sage training, the first filial piety, the second sincere faith...... I didn't sleep, I didn't sleep! ”

After saying this, he found that there was no one around, and then he remembered that today was not the bad old man's class, he just wanted to lie on the table and sleep for a while before the boring arithmetic class began.

Since he didn't sleep in that bad old man's class, and he wouldn't go to his father to sue him, then there was nothing to be afraid of, the little fat man turned his head angrily, and glared angrily at the guy who disturbed his good dreams, "You are ......, ah, it's you!" ”

Seeing the extra person in the hall, the anger on the little fat man's face immediately disappeared, and he asked, "Hey, are you here to make food for us?" ”

The last time Shou Ning invited them to eat that strange thing, he still remembered it, the imperial chef in the palace tried it a few times, but he couldn't make that taste at all, he had been thinking about it for two days.

"It's not." Li Yi shook his head and said.

Ask this kind of question as soon as you meet, no wonder this prince can grow so "strong" at a young age.

The little fat man slapped the table, pretended to be majestic, and said, "I am Li Han, the king of Jin, I order you to go to the Shangshi Bureau immediately and cook the same meal as last time......

Li Yi looked around at his surroundings and was indifferent to the words of His Royal Highness the King of Xiao Jin.

Last time, it was because of the old emperor's decree and the face of Tsundere Lori, but now it's different, he is not a royal cook, and he has no obligation to cook for them.

"You, you dare not listen to me, believe it or not, I let my father beat your board!" Seeing that Li Yi was indifferent, the little fat man raised his eyebrows and threatened.

Dealing with bear children, Li Yi has rich experience, and Xiong Huangzi is just a kind of bear child, so there is nothing to be afraid of.

Li Han, as a prince, has always wanted the wind and rain in the palace, in addition to being afraid of his father, the eldest sister, Shouning, Li Li, who will bite, the bad old man, the other bad old man, who else ------ afraid of?

In short, a cook from the Shang Food Bureau dared to disobey his orders, which made His Royal Highness the King of Jin feel very annoyed.

"Dare to be disrespectful to me, you wait, I'll tell my father today!" Li Han gritted his teeth and looked at Li Yi and said angrily.

If you don't beat him with a board, you can't relieve your anger, but you can't beat him too hard, otherwise who will make him good food?

Not long after Li Han's words fell, seven or eight figures poured in from outside the door, men and women, led by Princess Shouning.

"Ah, why are you here?" When she saw Li Yi, Princess Shouning was surprised.

Among the princes and princesses, a few people have seen Li Yi, but they only thought that he was the cook of the Shang Food Bureau, and the last time they didn't eat hot pot with Shou Ning, it was the first time they saw him.

The eunuch came over and said with a flattering smile: "Your Royal Highness Princess, Li Xianzi will be your Highness's arithmetic gentleman in the future." ”

Li Yi glanced at him meaningfully, this guy had a blue face when he was in front of him, but he smiled so brightly when he faced the princess, this is naked discrimination.

"Sir?" After Li Han, the king of Jin, was stunned, his face was sluggish.

When will the chefs of the Shang Shi Bureau be able to be their husbands?

Princess Shouning didn't care about whether Mr. was Mr. or not, and said with a look of surprise: "You will teach me how to make hot pot later, I didn't learn it last time." ”

"We'll talk about it later." Li Yi nodded, looked at a group of princesses and princes and said, "Since all your highnesses have arrived, then let's start." ”

Perhaps it is precisely because of the special status of the princesses and princes that they are more obedient to the rules, without the temptation of stories, they all return to their positions one by one, and sit upright, even Li Han, who was going to beat him just now, did not make any more outrageous moves.

First, he asked Shou Ning to introduce the princess and prince present, and after Li Yi wrote it down, he asked her about the progress of the arithmetic class.

The answer was that they were still in the learning stage of Arabic numerals, and the previous arithmetic teacher was teaching them how to convert numbers written in Chinese characters into Arabic numerals.

In other words, their way of mathematics is still in its most primitive infancy.

Blackboards and chalk are not available in this world, and most of the courses they have to learn are taught, but they can't understand math with just one mouth.

Fortunately, the previous arithmetic gentleman also understood this truth, and he pasted the white paper on the erected wooden board and wrote with a brush, which was similar to the blackboard of later generations.

"Before we start teaching, we do a thorough test." Li Yi turned around and wrote on the white paper with a brush.

Thirty-six, four hundred fifty-one, six thousand eight hundred thirty-two, eighty-nine thousand five hundred sixty-three, seventy five hundred seventy-three thousand four hundred sixty-seven......

When the princes and princesses were still wondering what the test was, Li Yi spoke again, "You write these numbers on paper with Arabic numerals......

Li Yi looked at Li Han, who was looking around, a smile appeared on the corner of his mouth, and said, "His Royal Highness the King of Jin, you come up and write ......"
