Concubine Shizi, she convinces people with cubs

Chapter 218 This Method Is Awesome

A total of twelve books, even for a proficient like her, it would take at least seven days to complete!How could Luo Wanshu do it?

She looked at the account book blankly, and murmured, "Are you sure you checked it? Did you lie to me?"

"Sister-in-law, if you don't believe me, you can see for yourself."

Song Qingyun hurried to the table and sat down, spread out the ledger, and checked it.As soon as she turned two pages, she smiled: "Wanwan, what are you writing here, are you writing ghostly symbols? My sister-in-law knows that you want to finish the work as soon as possible, so you can't use such things to fool people."

Luo Wanshu didn't get angry, moved a chair and sat down beside her, and then pulled out a piece of paper from a stack of ledgers.Written on it are the most basic nine numbers, decimal points, and definitions of the four arithmetic operations.On the back of the paper is the ninety-nine multiplication table that she wrote silently.

She smiled leisurely: "Sister-in-law, don't worry, if you want to understand my account book, you must first know what Arabic numerals are."

Song Qingyun: "?"

Next, Luo Wanshu explained to her the most basic mathematical operations in an orderly manner.The most urgent task is to let Song Qingyun understand what she wrote, so what she said is not exhaustive, but Song Qingyun still understands.

She is very good at doing business and is very sensitive to numbers. When she was a child, she didn't need to look at the ledger when she was a child, and her mental calculation speed was top-notch.

At first, she looked at Luo Wanshu with scrutiny and questioning, but when she got to the back, her eyes were full of enthusiasm.

How could she never have thought of such a simple expression and calculation method before!Surely it is man who created these things, not God?

Song Qingyun has the same idea as Luo Wanshu at the moment, if "mathematics" can be popularized, it will definitely benefit all people!

After Luo Wanshu finished explaining, she curled her lips into a smile: "Sister-in-law, do you still think I'm playing tricks when you look at my account book this time?"

Song Qingyun was holding the ledger, her hands trembling slightly.When she was pleasantly surprised, the end of her eyes turned slightly red, as if she had applied rouge. "Wanwan, how did you come up with it!"

"Sister-in-law, you think highly of me. I don't have such a great ability." Luo Wanshu waved her hand, "That child Rurui taught me. He learned from his biological parents and teachers."

Hearing her words, Song Qingyun took a deep breath, and said firmly: "His family background must be unusual. This kind of knowledge is not something that will not be spread, right?" Song Qingyun was worried that Luo Wanshu would take advantage of her.

Luo Wanshu really didn't think much about this aspect, and said after deliberation: "I don't think so. Listening to the little milk baby, there is no one he knows who knows how to use numbers. Maybe the place where he lived before and the big Zhou has no contacts, otherwise this knowledge would have spread to the Central Plains long ago."

"Yeah." Song Qingyun turned her attention back to the account book, "It's really beautiful, like a gift from God."

She couldn't put it down so much that Luo Wanshu laughed: "Although I have only learned simple calculations now, I don't think mathematics is so simple. If I have the opportunity in the future, I would like to study further. As for this I can teach the method of bookkeeping to our accountant first. As long as a small number of people learn it, it will greatly save our manpower, material resources and time."

Song Qingyun nodded heavily: "That's the reason. Wanwan, you completed this task beautifully, sister-in-law will give you the money now."
