Chapter 158 Multiplication Table
Zheng Sisi smiled slightly, then stretched out her hand, pointed to the multiplication table, and explained softly and patiently: "The multiplication table is a little secret for fast mental arithmetic! If you want to learn multiplication well, you must first understand addition. You see, like 1x1=1, this actually means that 1 added together is only 1; for example, 1x1=2, which means that 2 added together is 1..." As she spoke, she gently tapped each number and equation with her fingers, as if guiding the students into the wonderful world of mathematics.
He then pointed to the multiplication table of 2 and explained: "Look here, 2 times 2 equals 4, which means that two 2s added together equal 4; and 2 times 3 equals 6, which means that two 3s added together equal 6." While speaking, he also used his fingers to gesture the corresponding addition operation on the table to help everyone better understand this concept. This vivid explanation method gave the students a deeper understanding of multiplication.
Zheng Sisi's explanation brought the group into a wonderful world of mathematics. They all relied on abacus for calculations, and some did mental arithmetic, but it was only for small numbers. They couldn't calculate large numbers or made mistakes, but this multiplication table could quickly calculate large numbers.
After listening to Zheng Sisi's explanation, several people looked at her with admiration.
Zhong Ruiyu looked at Zheng Sisi with starry eyes and said, "County Lady, ah, why do I feel it is smoother to call you Miss Zheng?
Miss Zheng, you are really amazing. You can remember such a complicated formula table. It's amazing."
Zheng Sisi said proudly: "Of course."
In fact, she was embarrassed to discourage them. Nowadays, all the children who go to kindergarten can do it. Some of those who have received good early education can recite 300 Tang poems at the age of three, not to mention the multiplication table.
Zheng Sisi still asked the Third Prince: "Third Prince, do you think this digital accounting method is feasible?"
The third prince nodded affirmatively: "It's feasible. If you learn Arabic numerals well, it will be much easier to do accounting in the future."
The third prince pondered for a while and said, "Can this Arabic numeral be promoted throughout the country? If I ask you to teach at the church academy, would you be willing?"
Zheng Sisi said: "It's not difficult at all, as long as they want to learn, I can teach them anytime.
But I will first teach Shopkeeper Cui and a few of my maids to see if they are capable of learning. "
The Third Prince nodded: "No problem. It will take time for me to report this to my father and organize people to learn. By then, your maids will have learned it."
Zheng Sisi: "Okay, you guys recite the formula table first. You have to recite it fluently, especially you two. There will be a lot of account books that you will need to look at in the future." Zheng Sisi pointed at Zheng Zhiyuan and Zhong Ruiyu.
The two were not interested in looking at the account books, but they couldn't let Miss Zheng do everything alone, so they nodded and agreed.
The three of them had been immersed in reciting a few mnemonics, and continued reciting after having lunch at the county lady's mansion.
During this time, Zheng Sisi copied several copies, and called several maids and Li Ma to learn Arabic numerals and formula tables. Zheng Sisi gave them tasks: "Chun Tao and Xia He are in the mansion. You have to teach Manager Cui how to use Arabic numerals to keep accounts. It is best to teach everyone in the mansion to learn. Those who can't read can recite the formula tables. I will check them when I return to the mansion. The same applies to those who go out with me. They also have to learn well. I will reward those who pass my inspection."
The maids were both distressed and excited when they heard this. They were distressed because they were afraid they would not be able to learn, but they were excited because the county lady was giving them another reward. It was such a contradiction.
