"Yes, because there are nine rows and nine columns, it is called the nine-nine multiplication table. Mi already has some basics in addition and subtraction. It will definitely not be too difficult to learn this." Mag looked at the neatly arranged stairs. The multiplication table was neat and clear, and he put down the pen with satisfaction and smiled.
"Then what's that cross in the middle?" Amy asked, pointing to the 'x' with some confusion.
"This is a multiplication sign, which means the same thing as multiplication. This makes it simpler." Mag explained with a smile, letting Amy sit down on the chair next to her and pushing the multiplication table over a little, "Where is this multiplication table? , only my father can do it, I only need to remember eighty-one items, and then learn the decimal system well, then I can solve most of the arithmetic that needs to be used in life."
"Wow, Father, you are so awesome. Last time, Teacher Luna told Mi that if she wanted to memorize the multiplication table, she needed to memorize 1,770 items. Mi only remembered about 100." Amy looked at Mag with admiration. Unexpectedly, my father not only has beautiful handwriting, but also has simpler calculation methods than Teacher Luna. It is really amazing.
Although it was a bit uncomfortable to stand on the shoulders of ancient Chinese sages, the feeling of being worshiped by his own girl really made Mag feel so happy. He pointed to the first item in the upper left corner with a smile and said: "Then what are we doing today? Let’s study the first column first. The numbers on both sides of the multiplication sign are the multiplication sign, followed by the product, which is the result of the calculation..."
Mag explained the structure of the multiplication table to Amy in detail. Under the teaching of Teacher Luna, Amy did have some mathematical foundation. At least she understood the meaning of each number, and she also had certain concepts of adding and subtracting numbers. However, there is no base system in mathematics in this world, so he spent a lot of time slowly letting Amy understand the meaning of the base system.
The most gratifying thing about Mag was probably that Amy had no doubts about anything he said. Even if it completely subverted what Teacher Luna taught her, she unconditionally chose to listen to him and quickly accepted the concept of decimal multiplication. .
"One to one equals one, one to two equals two..." Amy chanted along with Mag. The girl's memory was pretty good. After chanting along with Mag for a dozen times, she memorized the first column.
Mag struck while the iron was hot and took her to read through the entire multiplication table twice to give her an overall feel.
"But Father, what's the use of remembering this?" Amy read it several times to herself, looked up at Mag with some confusion and asked.
"This is very useful." Mag smiled and pointed to the multiplication table, "Look, we now sell a portion of Yangzhou fried rice for 600 copper coins, which is 6 gold coins. Just like Grandpa Mo Bai just ate four portions , that is 4x6=24, you know the result directly, you don’t need to count them one by one with your fingers, isn’t it very convenient for you?”
"It's really 24 gold coins!" Amy's eyes suddenly lit up. She had spent a long time calculating the 2,400 copper coins in her mind just now, but her father easily got it using this formula. This multiplication table is really easy to use. She said enthusiastically: "Father, I want to learn, I want to learn this multiplication table! After learning it, Amy can really help my father."
"Okay, let's learn three columns today and learn the rest tomorrow." Mag nodded with a smile. The most important thing in learning is initiative and enthusiasm. Amy has both of these, and I believe she will be able to master them soon. Multiplication table.
Noon time passed while Amy was reciting the multiplication table. Except for Mo Bai, no other customer entered the restaurant, which showed how deserted this corner of Aden Square was.
However, after selling four portions of fried rice, Mag felt relieved. At least he didn't have to worry that the taste of Yangzhou fried rice was not suitable for people in this world. Judging from Mo Bai's reaction, the effect of fried rice on relieving muscle fatigue is also effective for him, and he may become a regular customer in the future. This is good news.
"Three-forty-two, three-fifty-five, three-six...three-six...three-six...three-six is too difficult..." Amy looked up at Mag with some grievances. This was her fifth time here. I couldn't carry it anymore, tears welled up in my eyes.
"Okay, let's memorize it until 355 today. Rice is already very good. Most friends can only memorize the first column for the first time. It's best to memorize the following tomorrow. Step by step is the best." Mag reached out to put away the multiplication table and smiled and rubbed Amy's hair. This reminded him of the video he had seen in his previous life of a girl crying while reciting the multiplication table. Sure enough, she was the same age and had the same worries.
"Really?" Amy, who originally thought she was going to be scolded, lit up again when she heard Mag's words. Her father actually thought that she was better than her other friends.
"Of course it's true. When did father lie to you?" Mag looked into Amy's eyes and nodded seriously.
"Well, father will not lie to Mi, so Mi Ming must keep his back." Amy nodded, with a bright smile on her face, feeling a little more confident.
Mag put the multiplication table behind the counter. It was past dinner time, and no one would come to eat. Looking at Amy's messy hair, he simply walked to the door, turned over the open sign, and locked the door from the inside. Then he took Amy's hand and said: "Let's go, father will help you wash your hair and take a bath, and become a clean fairy."
"Should we boil the hot water first and get the barrel?" Amy looked up at Mag and asked.
"No, there are pipes with hot water directly upstairs, as well as a bathtub." Mag smiled and shook his head.
"Is it like a kitchen faucet?" Amy said in surprise. That thing her father called a faucet was so magical. Just turn it and clear and sweet water would come out, like magic.
"Well, yes." Mag nodded, holding her hand and going upstairs. Amy's understanding of the world had just begun, so she was just curious about the modern things at home, and didn't have too many entanglements.
Amy, who saw the bathtub for the first time, quickly adapted to it. She sat in the bathtub and fluttered her feet, holding the white foam in her hands and giggling. She looked at Mag and said happily: "Father, this bathtub is so fun. And these bubbles are so fragrant and smell so good.”
"Well, this is a shower gel for bathing. What I have in my hand now is shampoo, which is used to wash my hair. After washing, my hair will be very clean and fragrant." Mag said with a smile, his hands a little He awkwardly applied the shampoo to Amy's hair and said softly: "Close your eyes, it will be very uncomfortable if the shampoo gets into your eyes."
"Well, the rice will become as fragrant as father." Amy closed her eyes obediently.
Mag gently rubbed Amy's hair. Although the movements were a little clumsy, they were more than delicate. She carefully separated the hair that was stuck together. In fact, Amy's hair was still very soft.
Bathing and washing a friend's hair is indeed a technical job. Anyway, after Mag helped the guy take a bath and wash his hair, his clothes were almost wet. However, looking at the guy wrapped in a bath towel, he also put it aside. Mag was a little worried about the skirt she had worn, and asked tentatively: "System, do you still sell clothes?"
