Concubine Shizi, she convinces people with cubs

Chapter 212 Arabic Numerals

Luo Wanshu looked at the ledger and sighed: "I don't want to make some money..." She still owes Carpenter Chang more than 100 silver.

The little milk baby hugged her whiningly: "Mother, you have worked hard, my baby will rub your hands for you."

"No, mother is not just for you..." Having said this, Luo Wanshu stopped.No, she worked so hard to make money for Qin Chi, what did she get?This man sent her a textbook!
In an instant, her heart became unbalanced.

The difference between the things she gave was too big, she wanted to quit.

Thinking of this, she angrily pushed the ledger forward, as if they were Qin Chi.

"Mother, are you not going to continue writing?" Rarity asked cautiously.

The word "don't write" hovered in her mouth for a long time, but she still didn't say it.

Finally, she reluctantly said: "Write." What can she do?The deposit has been paid.She doesn't care about men like Qin Chi, hum.

The little milk boy helped Luo Wanshu cheer up: "Mother is the best! Mother, come on!"

Luo Wanshu laughed: "Don't be a rainbow fart, go and practice your calligraphy."

"Hey, that's great." The little milk baby withdrew her little hand, and before turning her head, she muttered, "Why doesn't mother use numbers to keep accounts?"

Luo Wanshu heard what he said, and immediately asked: "What number?" Aren't the ledgers full of numbers?

The little milkman looked at her and replied, "It's Arabic numerals."

Looking at Luo Wanshu's face full of doubts, the little milk boy said as usual: "Okay, it seems that there are no numbers here. I'll write it down for my mother."

He is recognized as smart, has a good memory, and learns a lot ahead of his peers.For example, reciting poems, reading popular science books, simple English, numbers and simple calculations.

Luo Wanshu posted it, and saw that he took a clean white paper, wrote a series of symbols on it with a brush, counted them, and there were ten in total.

"What's all this?" Luo Wanshu asked after he finished writing.

Little Milkman explained to her one by one: "These are ten Arabic numerals from 0 to 9. When they are combined, they can represent various numbers, such as one hundred," Little Milkman wrote below One "vertical" and two "circles", "is 100."

Luo Wanshu compared the symbols above, and it was true.

"The gestures are so few and clear enough." Her eyes lit up, "What if it's 550 and [-]?" This number needs to be written in seven characters on the account book, with a lot of strokes.

But the little milkman wrote down the symbol "1555" on the paper without thinking about it.Compared with Chinese characters, the time is greatly shortened!
Luo Wanshu said to him in shock: "Your parents taught you this too?"

"Well, my dear's governess taught some too."

Luo Wanshu vaguely felt that if these symbols were popularized, it would set off a revolution in the entire Great Zhou.

She thought for a while, and then asked: "What if I want to express one tael and a half silver?"

"Just use a decimal point." The little milk boy clicked on the paper, and then wrote down "1.5"

"Half of 1 is 0.5, and four tenths of one is 0.4." The little milk boy explained.

Even though Luo Wanshu doesn't like to study, she is actually very smart. Once he said it, she understood it.

"The decimal point is really a wonderful use! Baby, are there any more?"

The little milk boy tilted his head and thought for a while: "The rest is simple calculations, such as the nine-to-nine multiplication table or something."
