"That's right, because it has nine rows and nine columns, it's called the nine-nine multiplication table. Xiaomi already has some basics of addition and subtraction. It won't be too difficult to learn this." Mag looked at the neatly arranged stairs. Shaped multiplication table, both horizontal and vertical are very neat, the handwriting is clear, put down the pen in satisfaction, and said with a smile.
"Then what is the little fork in the middle?" Amy asked, pointing at the 'x' with some puzzlement.
"This is a multiplication sign, which means the same thing as multiplication, so it's more concise." Mag explained with a smile, asked Amy to sit down on the chair beside her, and pushed the multiplication table over, "What about this multiplication table?" , only my father can do it, I only need to memorize the eighty-one items, and then learn the decimal system well, and I can solve most of the arithmetic that needs to be used in life.”
"Wow, Father is amazing. Last time Teacher Luna told Xiaomi to memorize 1770 multiplication tables, Xiaomi only memorized about 100." Amy looked at Mag with admiration, I didn't expect my father not only to write beautifully, but also to have a simpler calculation method than Teacher Luna, which is really amazing.
Although standing on the shoulders of ancient Chinese sages, it's a bit uncomfortable, but the feeling of being so admired by his own girl really makes Mag feel so happy, pointing to the first item in the upper left corner with a smile and said: "Then we Let’s learn about 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 composition of the multiplication table to Amy in detail. Under the teaching of Teacher Luna, Amy does have some mathematical foundation. At least she understands the meaning of each number and has a certain concept of addition and subtraction. However, mathematics in this world does not have bases, so he spent a lot of time slowly letting Amy understand the meaning of bases.
The most gratifying thing for Mag is that Amy has no doubts about everything he said. Even if it completely overturned what Teacher Luna taught her, she chose to listen to him unconditionally, and soon accepted the idea of decimal multiplication. concept.
"One one gets one, one two gets two..." Amy followed Mag to read, the little girl's memory is pretty good, after following Mag a dozen times, she memorized the first column.
Mag struck while the iron was hot, and led her to read through the entire multiplication table twice, first to give her an overall feeling.
"But Father, what's the use of memorizing this?" Amy read it a few times by herself, looked up at Mag with some puzzlement and asked.
"This one is very useful." Mag smiled and pointed at the multiplication table, "Look, we now sell a Yangzhou fried rice for 600 copper coins, which is 6 gold coins, just like Grandpa Mobai ate four servings just now. , that is 4x6=24, knowing the result directly, no need to count by fingers, is it very convenient, don't you think?"
"It's really 24 gold coins!" Amy's eyes lit up all of a sudden. Just now, I calculated the 2400 copper coins in my heart for a long time, but my father used this formula table to get it casually. This multiplication table is really easy to use, and he said enthusiastically: "Father, I want to learn, I want to learn this multiplication table! After learning Amy, I can really help my father."
"Okay, then 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 is not lacking in both of these, and I believe she will be able to master them soon. Multiplication table.
Noon passed while Amy recited the multiplication table. Except for Mo Bai, no second customer entered the restaurant, which shows how deserted this corner of Aden Square is.
But after selling four sets of fried rice, Mag felt much at ease, 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 in relieving muscle fatigue is also effective for him. Maybe he will be a regular customer in the future. This is good news.
"Three forty-two, three-five-five, three-six... three-six... three-six... three-six is too difficult..." Amy looked up at Mag aggrievedly. This was the fifth time she couldn't recite it here. , Tears rolled in the eyes.
"Okay, let's recite up to three fifty-five today. Xiaomi is already very good. Generally, it is rare for children to finish the first column for the first time. It is best to recite the rest tomorrow. Step by step is the best." Mag reached out to put away the multiplication table, and rubbed Amy's hair with a smile. This reminded him of a little video of a little girl crying on the back of the multiplication table that he had seen in his previous life. It was the same age and the same trouble. .
"Really?" Amy, who thought she was going to be lectured, heard Mag's words, her eyes lit up again, and her father actually said that she was better than other children.
"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 Xiaomi, so Xiaomi will definitely take care of her back tomorrow." Amy nodded, with a bright smile on her face, a little more confident.
Mag put the multiplication table behind the counter. It will be past meal time, and no one will come to eat. Looking at Amy's messy hair, she simply went to the door and flipped the open sign, and locked the door from the inside. Then he took Amy's little hand and said: "Let's go, father will help you wash your hair and take a bath, and become a clean little fairy."
"Then we need to boil the hot water first and get the wooden bucket?" Amy asked, looking up at Mag.
"No, there are water pipes with direct hot water and a bathtub upstairs." Mag smiled and shook his head.
"Is it like the faucet in the kitchen?" Amy asked in amazement. The thing called a faucet by my father is so magical. Just turn it and there will be clear and sweet water, just like magic.
"Well, yes." Mag nodded, and took her little hand upstairs. Amy's understanding of the world was just beginning, so she was just curious about the modern things at home, and didn't have much entanglement.
Amy, who saw the bathtub for the first time, quickly got used to it. Sitting in the bathtub, her feet fluttered, she giggled with the white foam in her hands, looked at Mag and said happily: "Father, this bathtub is so fun. And these bubbles are so fragrant and smell good."
"Well, this is body wash for bathing. What I have in my hand 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 Clumsily put the shampoo on Amy's hair, and said softly: "Close your eyes obediently, it will be very uncomfortable if the shampoo gets into your eyes."
"Well, Xiaomi is going to become as fragrant as my father." Amy closed her eyes obediently.
Mag gently rubbed Amy's hair. Although the movements were a bit clumsy, they were more meticulous, and carefully separated the bonded hair. In fact, Amy's hair was still very smooth.
Bathing and washing a child's hair is indeed a technical job. Anyway, after Mag helped the little guy take a bath and hair, his clothes are almost wet, but looking at the little guy wrapped in a bath towel, there is still Mag was a little distressed by the little skirt she wore beside her, and asked tentatively, "System, do you still sell clothes?"
