pastoral pretty girl

Chapter 56
"What? Don't you think it's too little? Then you make a price."

The old lady likes this, and she really doesn't care how much silver it is. Besides, in the capital, 20 taels of silver is normal for a meal.

"..."

Song Qingge was dumbfounded, she was really rich and powerful.

"Ahem... old madam, I don't need so much. I estimated the price before I came here. Is there a price for one penny per catty? Is there a scale in the house? Just give it to me according to the weight." Although she is short of money, she can't deceive people. .

20 taels of silver, in fact, many old ladies like Xiao Jinyi and are giving her alms.

But she wants to earn money by her own ability, so she doesn't need this kind of help.

The old lady was stunned for a moment, she was about to say something, but was stopped by Zhang Qingshan, "Just as the girl said, let the accountant come to someone."

Hearing Zhang Qingshan's words, the old lady didn't say anything, and asked someone to call the accountant.

"It's a total of 21 catties and four liang." Someone in the house weighed it in front of Song Qingge, "Madam, wait a moment." After saying that, he picked up the abacus at hand and fiddled with it.

"Don't bother, it's two taels of money and forty wen in total. If you make it up, just give me two taels of silver." Song Qingge was very happy when the price he wanted was sold.

Including the two taels of silver she got from selling the recipes, she made a total of four taels of silver on this trip today. After deducting the two taels of silver for repaying the debt, there is still two taels of silver left, which is enough for her and Xiao Jinyi to live for a year.

"Huh? It's really two taels of money and forty cents. You've already calculated it at home?"

After Song Qingge finished speaking, the accountant raised his head and said in surprise.

He calculated it with an abacus. How could she be so fast?

The accountant was just a little stunned, but Zhang Qingshan sat up straight from the chair, shocked in his heart, he, Dabao, and the old lady just caught a lot of pine nuts, even if they were calculated at home, the number changed after these.

In other words, the answer she gave right away was really calculated by her.

But I haven't seen her use an abacus to give an answer immediately after telling the weight. How did she do it?
"Girl, sit here." Zhang Qingshan was calculating in his heart, but his face was calm, beckoning Song Qingge to sit over.

"Old man, I'm not in charge of peeling pine nuts." Song Qingge said with a smile after sitting over.

She really liked this old man in coarse clothes, and felt that he was very close. The Zhang family was a rare good person she met after she came to this world.

"Peeling pine nuts is the work of that brat. The old man asked you, have you ever been to school?"

Song Qingge was slightly stunned, not knowing what he meant by asking this sentence, she nodded and said: "Mother asked Mr. Qingge to teach Qingge for a few days."

The original body has also read books, although after literacy, I read those sour poems every day.

It is a gift for women to be ignorant, very few learn to read and write, only women from wealthy families and officials' families can study, this surprised Zhang Qingshan.

"The old man asked you, how did you calculate it just now?"

"..."

Only then did Song Qingge understand why Zhang Qingshan called her here, "It's very simple, they are all integers, simple multiplication, mental arithmetic is fine, it's nothing special."

It's nothing in her eyes, but in the eyes of others, it's something a genius can do.

"Multiplication? Mental arithmetic?" The accountant was most interested and asked hastily.

"..."

Song Qingge looked at everyone's curious and expectant eyes, and she suddenly understood that there is no multiplication formula in this world, so...

I wonder if she has published a book about multiplication formulas, will anyone buy it?
(Remarks: In ancient times, one tael of silver could be exchanged for different copper plates in different periods, and the hexadecimal system was used, but... Xiaoyao's calculation skills are not very good. It is equal to one hundred copper coins~ hahaha~ If Xiaoyao is dizzy, that would be a joke...)
