McGonagall froze for a moment, and quickly realized that Amy must have felt that she hadn't been able to help because she hadn't succeeded in cashiering independently just now.
Putting down the bowl in his hand and looking at Amy's little eyes, Mag couldn't help but feel a little distressed. It seems that the little guy is still a little unconfident. In fact, in his eyes, Amy, who is only four years old, can do these things very well.
"Who said, how can our millet be useless? Most of the four servings of fried rice sold today are due to millet's credit. Secondly, four bowls of fried rice cost 2400 copper coins at the cash register. Millet was right, but Mobai Grandpa doesn't have so many copper coins on him, so he can only use this more beautiful and valuable gold coin as a substitute." Mag looked into Amy's eyes and shook his head seriously.
"Really?" Xiaomi listened to Mag's words, his eyes became brighter and brighter, but he was still a little unconfident.
"Of course it's true. Xiaomi hasn't seen gold coins before. It's my father's fault, because my father didn't even earn a single gold coin before. If I have to say who was wrong, it's because I didn't tell Xiaomi silver coins earlier. Gold coins, dragon coins, and copper coins can all be used to buy things, I should reflect on it, and hope our little Amy can forgive me." Mag nodded, with a somewhat remorseful expression on his face.
"No, how can you blame my father, my father is the best for Xiaomi." Amy shook her head vigorously, lowered her eyes, and said a little wronged: "Ms. Luna taught me, but...but so many I just can't bear to change my copper coins into so few gold coins, and there are too many to change, so... "
Mag's eyebrows trembled, and he almost couldn't help laughing. Amy's explanation was really cute, but seeing the little guy's timid eyes, he felt a little uncomfortable.
The external environment has a great influence on the development of a person's character, especially at an age like Amy who is slowly shaping the three views and forming habits.
The previous life was too poor, and humans and elves looked down on half-elves, which made her somewhat inferior and lacked self-confidence.
But fortunately, Amy is still young, and this kind of psychology is just a little budding. Mag believes that he can slowly help her adjust and become a confident little girl.
"In the future, I can't let Amy be ridiculed and looked down upon by others. She should hold her in the palm of her hand and become a happy little princess." Mag said to herself mentally.
But when it comes to arithmetic, the mathematics level in this world is really worrying. It is even worse than the arithmetic level of foreign passers-by in the previous life. It takes a while to calculate addition and subtraction with more than two digits.
In this world where culture is not popular, this is not a strange thing, but Mag suddenly had some ideas about building Amy's self-confidence.
China is naturally one of the countries with the highest average level of mathematics on earth, and the nine-nine multiplication table as an enlightenment has made a huge contribution.
"Eat this bowl of fried rice first. After eating, father will teach you a formula for arithmetic. After you learn it, you will be better than those students studying in Chaos Academy. It will be easier to collect money in the future." Mag stretched out his hand and kneaded it. Rubbing Amy's hair, he put the small bowl in front of her and said with a smile.
"Really? Better than those brothers and sisters?" Amy's eyes lit up all of a sudden, and she looked at Mag in disbelief. In her eyes, those brothers and sisters sitting in the classroom followed Lu Teacher Na is very good in class.
"Of course it's true. When did father lie to you?" Mag nodded.
"Yeah, Father will never lie to Xiaomi, and Xiaomi will learn obediently and seriously." Amy nodded, said seriously, and then began to eat obediently.
Mag looked at Amy, who was eating cute, and picked up a spoon to start eating. The nine-nine multiplication formula is a magic tool. If Amy masters it proficiently, it will be very easy to abuse those children who are still counting on their fingers. Confidence The first step of ascension begins here.
After eating, Mag packed the dishes into the kitchen, looked at the greasy dishes in the sink, didn't want to reach out, hesitated for a while, and said to the system in his mind: "System, do you sell dishwashers? "
"This system is not an electrical appliance mall." The system replied.
"In a word, sell or not? I will pay for it." Mag pouted.
The system was silent for a while, and gave a quotation in text: "Basic dishwasher, which can wash five plates and ten spoons at a time, price: 3 gold coins."
"This system really has an eye for money, and has no principles at all..." Mag rolled his eyes, seeing through the bottom line of the system's integrity, but the price is quite acceptable, and he said without hesitation: "So cheap? Then I If you want one, the money will be deducted from the credit line first."
"The payment was successful, and the dishwasher is in place." Another line of words floated by.
Mag looked at the bright silver dishwasher that was connected to the power supply on the stove next to him, his eyes lit up. This thing looked quite technological. He opened the lid and put a few plates and spoons in the sink into it. , Press the open button, and the lid will automatically open in less than a minute, and the plate inside has become brand new and shiny.
Modern technology is really convenient. Mag put the bowl and spoon away in satisfaction. Amy stood at the kitchen door, looking at Mag expectantly and said, "Father, what are we going to learn?"
"Ninety-nine multiplication table, Xiaomi, you wait for me, I'll get paper and pen, and try to memorize a few lines today." Seeing that there were no guests coming to the door for a while, Mag said, and went upstairs to get a piece of paper. A piece of paper and a pen were brought down, and then I sat at the table and silently wrote the ladder-shaped nine-nine multiplication table.
The writing in this world is naturally different from the writing on the earth, but the general writing is somewhat similar to the oracle bone inscriptions of Chinese characters. Numbers and Arabic numerals are the same, and the development of history always has some surprising similarities.
Mag inherited the memory of his predecessor, so he has fully grasped the text and language of this world.
"Father's handwriting is beautiful." Amy watched Mag writing the multiplication table, and praised Mag, looking at Mag with admiration. She used to think that Teacher Luna's handwriting was the most beautiful, but Father's writing is even more beautiful than Teacher Luna's, each one looks like it was carved out.
Mag was praised by Amy and looked at him with adoring eyes. When he was a child, he was forced to practice calligraphy for an hour a day and suddenly felt that it was worth it. Finally, someone appreciated his good calligraphy. Is Xiaomi good at writing?"
"Okay, okay!" Amy nodded happily, and looked at the rows and columns of numbers on the paper with some puzzlement, "Father, is this the nine-nine multiplication table?"
