Tang Xi smiled at him and said to Shopkeeper Fu: "Bother Shopkeeper Fu to lend me a set of paper and pencils." ”

"Oh, okay, let's go get the little one!"

Shopkeeper Fu said, walked out quickly, and after a while, he saw that he brought a set of four treasures of the study.

"Girl, please!"

Now, the table that was supposed to be set up for dinner is now being used as a study table.

Seeing that everyone was gathered around the table, as if waiting for her to unveil the mystery of "Arabic numerals".

Tang Xi chuckled, stepped forward to pick up a pen and paper, wrote 1 to 100 on the paper, and marked the corresponding numbers below.

For this picture-like number, everyone looked at it with a new look.

Tang Xi gave them the example he had just given them an example, and everyone was amazed.

Even the youngest Mo Zihao said with bright eyes: "This is really simple, I can understand it." ”

"This ...... That's too easy to use, isn't it? Shopkeeper Fu looked at Tang Xi happily and said, "Thank you girl for sharing this Arabic numerals." ”

"You're welcome!" Tang Xi blinked and said with a smile: "Shopkeeper Fu can just add two more dishes in a while." ”

"No problem, ten can do it too!" Shopkeeper Fu said: "Then this painting, ah no, this Arabic numerals, can the girl borrow a small copy of it?" ”

Tang Xi nodded generously, "Of course you can." ”

"Thank you so much!" Shopkeeper Fu thanked Tang Xi again and again, and then said, "Sit down, and the food will come up soon." ”

After that, he went out with the four treasures of the study.

"Xiaoxi, isn't your master a god descending to earth?" Mo Xule said hehehe.

"I thought so too." Tang Xi pretended to be serious and said: "He can do anything, but fortunately, I am smart, and I can learn so many things." ”

Xie Cheng raised his eyebrows and looked at her, his eyes flashing with a little curiosity.

The little girl is really getting more and more mysterious, and even he can't see through it.

Downstairs, Chu Tianyou was still waiting for Ancestor Xie to finish his meal, and then discussed something with him, but he didn't think that the shopkeeper Fu, who was originally excitedly carrying the four treasures of the study, came down with a smile again.

"Is this pie in the sky?" Chu Tianyou asked funny.

"yes!" Shopkeeper Fu nodded and said, "It's even more powerful than pie falling from the sky." ”

Shopkeeper Fu put the things on the counter, walked over with the paper, and happily spread it out to him, "Boss, have you ever seen this thing?" ”

"What is this?" Chu Tianyou frowned, "Who drew it?" Ghost Drawing? ”

"That's good stuff!" Shopkeeper Fu pointed to the words below and said: "The symbol above corresponds to the number of words below, you look at this, this circle is zero, and this vertical is one." ”

"Oh." Chu Tianyou disagreed, "What's the use of this symbol?" ”

"It's so useful!"

Shopkeeper Fu brought a pen and paper, calculated the algorithm that Tang Xi taught him, and then moved the abacus to calculate it again, Chu Tianyou, who was not very interested in it, was shocked at first glance.

"This ...... Who wrote it? ”

"Didn't you say the little one?" Shopkeeper Fu said: "It's the girl brought by the city lord of Xie, who said that her master taught her, it's simple and fast, and the result is very accurate." ”

"What her master taught?" Chu Tianyou was shocked and admired: "I can't imagine that there are such smart people in this world. ”

"The little one smelled a faint smell of Chinese medicine next to the little girl, although it was not too strong, but it could still be smelled if you sniffed it carefully." Shopkeeper Fu said with concern: "That little girl, could it be that she is sick?" ”
