Double-faced prince and concubine

After receiving the reward from the emperor, Xia Yue'er had no choice but to start working honestly.

Zhongli Ruixuan ordered people to tidy up two rooms in the yard of Zangshu Pavilion, one for them to write, one for manuscripts, and one for spare books and materials.

Looking at a thick "Character Library" on the desk, Xia Yueer suddenly felt a lot of pressure. She measured the thickness of the book with her hand and asked Cheng Ziyi: "Scholar Cheng, in this "Character Library", there are some things to say. Tens of thousands of words, right?"

The emperor sent Cheng Ziyi to assist Xia Yue'er, and he didn't just appoint someone, mainly because Cheng Ziyi was interested in simplified characters and was one of the people who advocated the promotion of simplified characters.

Cheng Ziyi is more than 40 years old, knowledgeable and handsome, just in response to the saying "a man is a flower at 40 years old". Cheng Ziyi, who is in his 40s, still looks personable and elegant.

"Returning to Princess Rui, there are a total of 36 characters in the "Character Library"." Cheng Ziyi replied seriously.

But Xia Yueer exclaimed: "I'll buy it! It's almost [-] characters, what kind of year of the monkey are you going to write!"

Fortunately, not every word has to be written, and some traditional and simplified fonts are the same, which saves a lot of trouble.However, Xia Yue'er is only responsible for writing simplified characters, as for compiling books, she has nothing to do.

Taking a piece of paper, Xia Yueer picked up the hard pen she "invented" and calculated on it: "180 characters, half a year, 180 days, divide 270 by [-], round up, and write [-] or eight characters a day. It’s ok, ok, not a lot.”

270 eight characters, can be done in an hour!Xia Yue'er thought again, if it continues like this, if the writing is finished in half a year, won't her clothing store not be able to open until half a year later?If you write a thousand words a day, isn't the speed much faster? It only takes two months to get it done!

Then, Xia Yueer wrote down the goal on a piece of white paper: "Total number of words: 50000 words, daily goal: 1000 words, scheduled completion time: 60 days." There are still 10 days of vacation in between!

When she finished writing, she asked someone to post it on the wall, only to realize that everyone looked at her with weird eyes.

Xia Yueer asked puzzledly: "Bachelor Cheng, Lord Cheng, why are you all looking at me like this? Is it too high a goal to write a thousand words a day?"

Cheng Ziyi kept shaking his head. Princess Rui's way of holding a pen and writing was very special, but they were not surprised by this.Cheng Ziyi pointed to the numbers on the paper and asked: "Princess Rui, you wrote these, but you said fifty thousand, one thousand, and sixty?"

"Ah, ha, yes!" Only then did Xia Yueer realize that there were no Arabic numerals in ancient times, but Arabic numerals are so useful, it would be a waste if they were not promoted, so Xia Yueer explained while writing on paper : "Yes, this is a number. For example, this circle is zero. This vertical one is one, this duck-like hook is two, these two hooks are three, and all the way back, it is 4, 5, 6, 7, 8, 9, ten is 1 followed by a 0, two 1s after 0 is one hundred, three 0s are one thousand, four 0s are ten thousand, and so on, ten hundred Hundreds of millions of millions of billions."

Cheng Ziyi and the four civil servants looked at these figures with surprise on their faces.Counting with these numbers will be much more convenient.

Seeing that everyone else was stunned, Xia Yueer scratched her head and smiled: "Hey, you don't have to look at me like that. These numbers were not invented by me, but by Indians. They were later spread by Arabs, so they are called Arabic numbers." number."

This explanation makes people even more puzzling: "Indians and Arabs, which country are they from? I have never heard of them."

Ga!How to explain this?In this ancient world, did India and Arabia exist?

"Well, India and Arabia are two places far, far away! Oh, don't worry about these details! You know that these numbers are very useful! It's very convenient to use numbers to calculate."

In order to prevent Cheng Ziyi and others from continuing to entangle in India and Arabia, Xia Yueer picked up a pen and wrote on another piece of paper: "Well, for example, the table of ninety-nine multiplication formulas, one by one gets one, one two gets Two... Nine Nine 81, look, it's clear at a glance."

Xia Yueer wrote out the entire multiplication table, which was still in the terraced field style, and made Cheng Ziyi and others look stupid.

Cheng Ziyi discovered something more important than writing simplified characters, so he plopped down on his knees in front of Xia Yueer, startling Xia Yueer: "Bachelor Cheng, what are you doing? Get up quickly, don't scare me like this , my heart is weak, and I can't stand being scared..."

"Princess Yue, please call us Arabic numerals first!" Cheng Ziyi said sincerely.

Scared to death, what a big deal!

Xia Yueer patted her chest and asked Cheng Ziyi to get up first, saying that numbers are easy to learn, as long as you memorize one to nine, you will be fine.She had taught Zhongli Ruixuan before, but Zhongli Ruixuan could learn it easily.

Therefore, Xia Yueer became a teacher for the bachelors, teaching them Arabic numerals, including decimal points, and some simple calculations.

I took a break at noon and continued in the afternoon, and the day passed quickly.

Jing'er came back from Shangwen Academy, chattering excitedly, talking about what she learned today, and saying that brother Yunze is so stupid, not as smart as brother Xipu, and brother Yihe is also very smart.

After talking for a long time, Jing'er suddenly remembered: "Mother, sir, we will learn arithmetic tomorrow. Jing'er remembers the arithmetic taught by mother!"

Xia Yueer thought it was funny when she thought of teaching Ziyi and others numbers today. It felt like she was teaching kindergarten children. It was really funny to see Cheng Ziyi and others looking studious and cautious.

"My lady, what are you laughing at?" Zhongli Ruixuan was about to laugh silly when he saw Xia Yue'er like that.

"Hey! It's nothing!" Xia Yue'er came back to her senses and asked Jing'er: "Does Jing'er still remember that I taught you the multiplication formula, recite it for me!"

"Remember, mother, Jing'er will recite it for you!" Jing'er really memorized it, and she memorized it smoothly. ?”

Xia Yue'er patted her on the head: "Yes, our Jing'er is so smart, of course he recited it correctly!"

After returning to the room at night to go to bed, Zhongli Ruixuan lay down on the bed and asked Xia Yueer: "My lady, how did you write in simplified Chinese today?"

Xia Yue'er was combing her hair, she put down the comb and sighed, "Hey, I haven't written a single word after tossing around all day!"

"Why?" Could it be that he was addicted to reading other books and didn't want to write?

"I have been a teacher for a whole day today, and my mouth is dry. I taught the bachelors how to learn Arabic numerals!"

"Oh!" Zhongli Ruixuan remembered that Xia Yue'er had taught him Arabic numerals, but he didn't use them seldom, he still remembered the numbers, but forgot their usefulness.
