Yun Genggen took the calculator he had exchanged, and felt a lot more at ease. Although it is only a small one, it is many times more convenient than the bulky abacus.

It was afternoon at this time, fortunately the weather was not hot today, Yun Geng fanned his fan and found a place to sit in the backyard of Fuman Building. I saw that the mint planted earlier had grown lush and green, which was very gratifying.

Since the new menu has been changed, there are more diners, and the amount that needs to be calculated is even greater. The account books of Fumanlou have always been sorted out by Yun Genggen himself, and every time he opens the messy accounts, he will inevitably be dizzy.

Yun Geng took a deep breath, and said to himself, I can't imagine that I would have the opportunity to experience the fear of being dominated by mathematics once in ancient times.

Yun Genggen shook her head helplessly, took out the calculator and fiddled with it, this can be described as her right-hand man. After she skillfully settled the accounts, streamlined the account book, and rearranged and transcribed the numbers, it was only an hour. Yun Geng propped his head, feeling comfortable in his heart.

Thinking of what Lin said about the tax before, Yun Genggen couldn't get interested in getting angry with her again, so he only took the rice paper and calculated it carefully.

Yun Genggeng, to put it bluntly, is also a modern person who has been doing it for decades, and the calculator is naturally more handy than the abacus in her hands. Fu Manlou's estimated income for the next month is about 200 taels, minus the tax of 30 and 1, and the cost and the monthly money of 19 chefs, Yun Genggeng's net profit for the next month is about 80 taels.

This is not a small amount for ordinary people, but compared with the big business of the Sifu, it can't help but seem a little shabby, and it is no wonder that the Lin family did not put himself in his eyes.

Thinking of this, Yun Genggen sighed lightly, she thought that she had done well enough, but in the eyes of others like the Lin family, it was just a surface. They don't know their toil, they don't know their thoughts, and the way the world has always been.

His eyes fell on the food box at the corner of the table, it was Si Linche who specially sent someone to send her, they were all freshly cut melons and fruits, and Yun Genggen laughed alone before he had time to eat them.

"Sister Geng, what are you doing here?" Seeing that she was distracted, Fan Tong poked his head over and said curiously.

"It's still too troublesome to settle accounts with an ordinary abacus." Yun Genggen came back to his senses and saw that although Fan Tong was a rough person, he was very studious, and he would come to ask her for advice as soon as he encountered problems in dealing with the restaurant before. Yun Geng nodded silently, then raised his hand to spread the rice paper in front of him, and replied.

Fan Tong looked down and saw that Yun Genggeng wrote on the paper all the ghost drawings he had never seen before, although these symbols were simple, but he had never seen or heard of them, which was really strange. I couldn't help but be surprised and curious: "Sister Geng Geng, what are you writing this?"

Yun Genggen naturally couldn't tell him the truth, so after a little thought, he had to explain: "This is an Arabic numeral, imported from the West, and I also learned it by accident before."

"Arabic numerals have the same meaning as the capitalized numbers we usually use for bookkeeping, but in a different way, which makes the calculation much easier."

"In this way," Yun Geng turned a few pages of accounts, and handed the capitalized figures of this month's Fumanlou expenditure to Fan Tong: "I'll teach you the basic way to write, and then you replace these capitalized numbers with Arabic numerals, whether I'm right or not, you'll know if you try it."

Although Fan Tong has never studied and only knows a few words, he is still smart. Seeing Yun Genggeng's sworn look, although he was suspicious, he didn't dare to refute Yun Genggeng's face, so he had to give it a try, and it was really as Yun Genggeng said, which was convenient for more than one level.

Fan Tong looked at the symbols slightly stunned, shook his head with some doubts, and the disbelief in his heart was confirmed by his hand: "This ...... I never thought there would be such a method. ”

Seeing his honest appearance, Yun Geng Geng smiled and said, "I will learn more from you Sister Geng Geng in the future, do you know?"

Fan Tong also nodded and smiled: "I know, I know, the sky is big, and the shopkeeper is the biggest."

After speaking, Fan Tong took out the ledger he carried with him to record the monthly money and copied the novel Arabic numerals, and turned around to think about it on the way to the back kitchen.

The back kitchen happened to deliver the dishes, and when I saw him like this, I asked, "What's wrong?" What to see? ”

Fan Tong handed him the notebook: "Shop for what Sister Geng Geng taught, Arabic numerals."

As he spoke, he taught the method that Yun Genggeng had just taught him to the few people around him, and everyone either discussed it or was amazed.

In the afternoon, Yun Geng was about to go to Si Linche, when he saw a young man in white standing at the door of Fumanlou.

Si Linche's complexion is pale, so the more obvious sense of youth and the strength of his age are combined with a just right amount of aggressiveness. When he laughed, he was extremely gentle, and when he didn't speak, his phoenix eyes were sharp and angular, and he was so confused that Yun Genggeng was dazzled.

"Geng Geng, what's wrong?" Seeing that Yun Genggen had been standing still, Si Linche took a few steps forward, rubbed her hair, and said with a smile.

"Not really." Yun Geng Geng lowered his head and quietly reddened the roots of his ears.

Si Linche deliberately teased her, and said in a low voice: "Lady, is this shy?"

"Don't talk nonsense, there are so many people," Yun Genggen patted him: "Why are you so busy and still here in person?"

Only then did the two return to the topic, Yun Genggen raised his eyes, and saw that Si Linche was followed by a carriage full of things, and wondered: "What are these?" Are you new to the stock? ”

"No, the weather will get cooler after a while, and since your mansion has been repaired, it is better to change these objects." Si Linche lifted the cover on the carriage and said, "I sent someone to buy some bedding, which are thin and thick, and they are comfortable to cover all year round."

"This ......" Yun Genggen only felt a little dizzy.

"Si Yi told me this morning that your mansion has been completely renovated, so why don't you go and have a look while it's still early?" Si Linche said warmly.

Since the key to this courtyard was given to Si Yi, Yun Genggen has not been to see it once. Originally, I was going to find time to take a look, but now I nodded and sat neatly in the carriage.

Yun Genggen lifted the curtain and saw Fan Tong standing at the door looking here, his heart moved, and he waved to him to let him come over.

Si Linche was outside the car and Si Yi was instructing matters, and he didn't notice this, Fan Tong came closer and asked, "Sister Geng Geng, what's wrong?"

Yun Genggen just suddenly cleared his throat about what the Lin clan was like in the eyes of these people, and said, "What do you think of Si Gongzi's mother, the Lin clan?"

"I heard that she is a very kind and kind person, and she will give porridge to the people in disaster years, and the neighbors also say that she is good." Fan Tong didn't think much about Yun Genggeng's question, and replied.

Yun Geng said twice and didn't speak again.
