Luo Jiashu's first thought was Luo Qinghe, after all, it could only be her, and now it is often unexpected.

"That's right." Luo Qinghe walked out of the house, "It's okay in the afternoon, I'll teach you arithmetic." ”

"That's a good feeling." Luo Jiashu grinned.

"Uncle, when you arrive, write down the mantra I said on paper, and everyone you want to learn will have a copy, and you will be able to remember it after a long time." Luo Qinghe proposed.

"Okay." Luo Yougen nodded and said yes.

Luo Jia hurriedly waved his hand to stop it, "Qinghe, why do you need a copy, just let the uncle write one, let's take turns to look at it, the paper is precious." ”

"Big brother has a point." Luo Jiashu said with a smile, "When the uncle writes, I will learn to write it on the ground, and it will be done, no, it is the same with the charcoal left over from the firewood burned on the wooden board, I used to write like this to memorize the words taught by the uncle." ”

The more Luo Jiashu said the back, the more aggrieved he became, he glanced at Luo Yougen pitifully, and then looked at Luo Qinghe, "Qinghe, arithmetic is easier than reading and literacy, right?" ”

Luo Qinghe chuckled, "It's simple, as long as you remember the mantra and then practice more, arithmetic is to do more, you can learn it." ”

"Qinghe, I believe in you very much, since you said so, the second brother will give himself to you with confidence." After Luo Jiashu finished speaking, he patted Luo Qinghe's shoulder.

"Big brother, let's go to the stove and find some charcoal that hasn't turned ash yet." Luo Jiashu pulled Luo Jiadi and went to pull the stove.

"Qinghe, go to my house with Jiashu to teach, there is a table inside." Luo Yougen said.

"Okay." Luo Qinghe nodded, and then looked at Luo Jiahe in the room, "Sister, sister-in-law, Xiaomiao, you come together, it's always good to have one more skill." ”

Because of Luo Qinghe's call, Luo Yougen and Luo Jiashu's house was crowded with people, and the people in the family came, and there was nothing to do on a rainy day, and they were very curious about what formulas Luo Qinghe wanted to teach, so they all gathered over.

The room where Luo Yougen and Luo Jiashu live, the space is the same as other rooms, that is, there are more furnishings in the house, after all, Luo Yougen is a reader, and there are more bookshelves, desks and chairs.

The desk is clean and tidy, and the pen, ink, paper, and inkstones on the desk are neatly placed without a trace of dust, and it can be seen that the owner loves them very much.

The books on the shelves all had traces of flipping, Luo Qinghe stepped forward and took a copy and flipped through it, there were many annotations in it, and looked back at the written "Zengguang Xianwen".

Luo Qinghe doesn't know much about this book, after all, when he used to study, he studied ancient classical Chinese, and he learned only those, and he also learned some of the "Analects", which is not suitable for Luo Qinghe, but although he can't understand the meaning thoroughly, he can generally understand it.

Luo Qinghe flipped through a few pages and knew that this book was mainly composed of witty words and good sentences, which was equivalent to modern good words and sentences.

But there are some differences, the modern ones are mainly beautiful sentences, but there are many truths in "Zengguang Xianwen", and enlightenment is very good.

"That's not enough." Luo Jiashu asked out loud when he entered the room, pulling back Luo Qinghe's thoughts.

Luo Qinghe hurriedly put the book in his hand back on the shelf, and saw that Luo Jiashu and Luo Jiadi had moved several small wooden boards by themselves, and there were several charcoal lying on the wooden boards.

"Use it first, it's not enough." Luo Laotian said.

"Oh." Luo Jiashu put things on the ground one by one, "Qinghe, okay." ”

Luo Qinghe nodded, "Second brother, put the wooden plank on this wall and put it vertically." ”

Luo Jiashu didn't understand what Luo Qinghe was going to do, but he acted according to his words and set up the plank.

Luo Qinghe picked up the charcoal and knocked it on the board, "Okay, I'll start talking, you all listen carefully." ”

Luo Qinghe is now the "teacher" standing in front of the "blackboard".

"Yes, second sister." Luo Jiamiao echoed the scene.

"I'll teach you numbers first." Luo Qinghe wrote zero to pick up on the wooden board in turn, and then it was hundred, thousand, and ten thousand.

"These fourteen numbers, used the most, no matter how big it is, it is almost impossible to touch, the number of money in the account book is almost composed of these numbers, to learn to calculate accounts, the numbers must always be recognized and written first." Luo Qinghe said, "There are not a few words, I will write them as if I am free, and I will be able to memorize them by rote." ”

Luo Qinghe put aside the wooden board with capital numbers, and Luo Jiashu cleverly put another wooden board on it.

"But I'm going to teach you the mantra, and it's not these numbers that I'm going to use, but these more concisely." Luo Qinghe turned around and wrote on the blackboard with charcoal, 0-10, the order is parallel to the one with capitalization, and the number position is parallel, "This corresponds to this, down in turn......"

"Memorize formulas, columns, all use simple these, but this can only be known by ourselves, after all, others may not know, so we must remember accordingly, see 0, can write zero, see 1, to be able to write one...... To achieve the ripeness of the melon, it is necessary to keep it in mind. ”

"Alright, you can take the plank and practice writing by yourself." After Luo Qinghe finished speaking, he went to get other wooden boards and began to write down the addition formula, subtraction formula, multiplication formula, and division formula.

Luo Yougen is literate, he was not busy memorizing, but curiously watched Luo Qinghe slowly write on the wooden board that he had never seen before...... Numbers, that's what Luo Qinghe called.

When Luo Qinghe finished writing, he looked back, good guy, and the countless lines of sight of Qi Shushu were closely looking at himself and the plank behind him.

"Qinghe, this is the mantra you said?" Luo Laotian asked.

"Yes." Luo Qinghe nodded, "As long as you memorize the formula, you can calculate the simple one, and the more difficult ones will have to be columnar, the columnar formula is not difficult, and if you memorize the formula, the columnar formula will almost be learned." ”

"That's a lot." Luo Jiadi was a little confused.

"That's all, and addition, subtraction, multiplication and division are all reversed, you can reverse it, anyway, these are remembered, and the arithmetic is even mastered." Luo Qinghe said with a smile, "I have to memorize it by rote, and I will test you later." ”

"Moreover, don't you want to go out to buy things or sell things in the future, and you can calculate it all at once, faster than those bookkeepers, even if you don't have an abacus, you can calculate it accurately?" Luo Qinghe said seductive words.

"Yes." Luo Jiashu expressed his thoughts in a loud voice, "If you do it, I don't believe it, I can't fix these dead things as a big living person." ”

"Let's do it together." Luo Jia responded to his second brother with a smile, and did not debunk his previous reading and literacy, and the appearance of being tortured by words "to die or not to live".

"Why don't you read it with me a few times?" Luo Qinghe asked.

"Okay." The crowd echoed.

After that, Lao Luo's family stumbled, and slowly and gradually uniformly "one by one, one by two, two by two......"
