Chapter 70: Teaching Addition and Subtraction Arithmetic

Zhou Cuihua once tasted the taste of sweet potatoes and potatoes, and was very interested in sweet potatoes and potatoes, and had to come to the field almost every day to go around.

Instead, it's for those melons, croissants, honey, tomatoes, peppers. Although she also takes care of it, she doesn't care because she has never seen the real thing and doesn't know if she can bear fruit.

The days passed like this, and whenever it rained, windy and thunderous, Liu Paner was especially worried that the wind would blow down the crops in the field.

It started to rain heavily again today, and Liu Paner sat at the door of her cave, looking at the pouring rain outside, slightly distracted.

Daughter Li Nan ran over and snuggled up to Liu Paner's side, "Mother, are you unhappy?" โ€

Liu Pan'er shook her head and smiled, "I'm not unhappy, I'm just worried that the storm will be too big and ruin our crops." โ€

Liu looked out worriedly, "Alas, I hope God will open his eyes and don't damage our crops." That's the capital for us to stay here! โ€

Hearing this, Li Nan also frowned, she was a child, and there was no way.

The mood of sorrow spreads from adults to children, and everyone is depressed.

Seeing that everyone was worried, Liu Paner patted her forehead, "It's useless to worry, then don't worry, let it be." It just so happens that it's okay today, so I'll check your recitation of the ninety-nine multiplication table first. If you can memorize it, I will teach you addition and subtraction. โ€

The children knew the importance of learning, and immediately began to scramble to recite the ninety-nine multiplication table to Liu Pan'er.

The children recited very fluently, and even the youngest Li Nan memorized them all.

The older Li Rong and Li Dabao, as well as Liu's two daughters, Li Fang and Li Li, can also recite fluently.

Liu Pan'er took a branch and wrote the Arabic numerals one, two, three, four, five, six, seven, eight and nine on the sand table, "Come, this is a simple counting method that I learned from a Fanbang person in the northwest." It's one, two, it's simple, it's just symbols. Make a note that this is a number that makes up all the numbers you can name. โ€

Li Nan was stunned for a moment, and hurriedly raised his hand, "You, how much is a hundred?" โ€

Liu Paner wrote a one on the sand table, followed by two zeros, "This is a hundred, composed of one hundred ones, or ten tens." โ€

"Fifty-nine, is it just a combination of a five and a nine?" Li Xiaobao asked directly, he seemed to have touched the doorway.

Liu Pan'er nodded, "Yes, this is fifty-nine." โ€

"Two nines, that's ninety-nine?" Li Rong asked, very curious, it turns out that you can count like this!

Liu Pan'er nodded, "Yes, Ah Rong is great." Come on, practice first, memorize these numbers, and I'll teach you well. โ€

"Hmm!" Then they should go down and write down the numbers on the sand table.

Liu, who was not far away, was surprised that the number was simple, and she also learned it, and she was very happy, and she would be able to count in the future.

Liu Paner saw that everyone had learned, and said with a smile: "Then I will teach you to add and subtract ยทยทยทยทยทยท today."

Vertically listed, the operation method is explained, no matter how large the number, the addition and subtraction can be calculated quickly.

Liu Shi saw that the children learned quickly, and she also learned, she was very happy, and when the rain stopped outside, she smiled and said, "Third brother and sister, what you teach is really simple, I have learned everything." โ€

Liu Pan'er smiled, "It's good to learn, it can always come in handy in the future." We don't want others to know that we know how to do arithmetic, we just want not to be deceived, we can calculate accounts, and we can use it in our later lives. โ€

"Okay, you keep learning, I'll go to the field and see if our crops are okay?" Liu smiled, put on a cloak and a hat, and went out of the cave.

Liu Paner was not at ease, closed the door of the cave, and said to Li Dabao and others: "You are at home, I will also go out to have a look." When you go out, shut the door so that nothing comes in. โ€

"Got it, mother, don't worry." Li Dabao should go down and not let his mother have worries.

Liu Paner came to the sweet potato field not far from the yard, there was a lot of water in it, and she used a shovel to dig a drainage ditch.

Sweet potatoes love drought, and too much water will affect the growth of sweet potatoes.

After putting the water in the sweet potato field in front of her house, Liu Paner went to the field with Liu.

The water in the terraces flows out automatically, and it's rice, so don't worry.

When I met Li Dashan on the way, I had already begun to check in the field, and I was more concerned than anyone else. After a while, more people came out of their homes and went to the fields to check.

Liu Pan'er saw that the rice field was fine, so she hurried to take a look at the crops in the dry land.

In some places, water accumulated, and Liu Paner and Liu dug drainage ditches to drain the water from the fields. In the south, except for rice, other crops do not need special watering.

Because of the humid climate, it rains every few days.

Liu Pan'er saw that the melon shelves were all there, and breathed a sigh of relief, "Fortunately, the shelves haven't fallen, if the fruit crops are about to break, it's a pity." โ€

Liu nodded, "Third brother and sister, you are still prescient." When you built the shelves before, you told us to tie the shelves as strong as possible. Now it's trouble-free, if you look at Village Chief Li's family, many of them have fallen. โ€

Liu Pan'er looked at Liu's fingers and saw that the seedlings in the melon field had fallen, but it was not serious, just help it up and consolidate it.

After the rain, the sun was shining high, and soon the temperature came up, scorching the earth.

The water vapor on the ground was quickly evaporated, and the crops in the field began to grow vigorously again.

These are new varieties, resistant to drought and flooding, and have high yields, and Liu Paner expects these crops to grow enough melons and fruits.

Can you build a house? Can you live a good life? That's it!

After Liu Pan'er came back, she saw that Zhou Cuihua was also releasing water, and reminded, "Auntie, those melon shelves in your field have fallen, you should hurry up and help them up." Be careful, it should be fine. โ€

When Zhou Cuihua heard this, her face was distressed, "It rained just now, and I was very worried. They went to protect the mud bricks, and they were not at home. When I finished putting the water out, I went to the field to have a look. โ€

"Auntie, don't worry, it's not much." Liu Paner smiled, comforting Zhou Cuihua.

After a while, Zhou Cuihua took tools and went to the field with her daughter-in-law to sort out the crops.

Yuanjia's daughter-in-law whispered: "Mother, I haven't seen those things, can I really produce things?" โ€

Zhou Cuihua rolled her eyes and retorted angrily, "There are many things you haven't seen, sweet potato leaves, you haven't seen them before, and now you don't eat better than anyone?" โ€

"Mother, I'll talk about it." Yuanjia's daughter-in-law has always been praised by the villagers as virtuous before, but now that there are Liu Paner and Liu, who are more virtuous than her, she can't be seen.

Therefore, Yuanjia's daughter-in-law has been unconvinced in private.

In the past, I fled the famine, and my stomach was not full, so I didn't have time to worry about these. But now that she has lived a stable life to the fullest, although she is tired, she has no worries about her life, and she can't starve, so her careful thoughts come again.
