Chapter 256: Green Bean Soup, Beautiful as Jade

The world Su Zhi came to was a dynasty that did not exist in the history she knew before, but it was almost the same as the Song Dynasty she imagined. However, many civilizations that should have appeared before the Song Dynasty did not appear. Instead, many people or things that had never appeared in the five thousand years of history she knew in her previous life appeared. Of course, they were roughly the same, but just changed in form. This was never a problem for Su Zhi. Instead, it made her life more exciting and free because she had mastered a lot of knowledge that was not here.

Here, there is an abacus, but no addition and subtraction. Without an abacus, it is easy to calculate simple numbers, but if the number is too large, it will be difficult, so the abacus is very important. And ordinary people don't need an abacus, they can count slowly.

Su Zhi taught the kids mung bean soup in Chapter 256. Yan Ruyu learned arithmetic not because she realized how troublesome it would be without an abacus, but because in her previous life, children had to learn to recognize words and numbers. Since she had memorized even the poems, she did not neglect arithmetic either.

Shen Zian was very surprised by the ten Arabic numerals, and also by the addition, subtraction, multiplication and division that Su Zhi said, which made Su Zhi realize that there was no such arithmetic method in this world. However, because Su Zhi surprised him too much, he just followed and learned this method, and didn't say anything else.

Su Zhi never thought about becoming a famous person. She knew that she had many things that could make her famous, such as poetry, songs, and this kind of calculation method. But she didn't plan to show off. She just wanted to work hard to make money, live a peaceful life with her husband and children, and be a leisurely landlord who counted money every day. Let others be great writers!

However, Su Zhi had never thought about hiding what she knew, and she would not be caught, so it was okay to talk about it. Moreover, if she kept it a secret after being discovered, it would make people suspicious. Now that Shen Ziju had discovered it, she did not care. She just explained it so easily. Chapter 256 Green Bean Soup, Yan Ruyu

Su Zhi was very relaxed and natural. However, Shen Ziju felt as if he had discovered something extraordinary.

"Sister-in-law, when you say adding and subtracting numbers, do you mean all numbers? No matter how big they are?"

Shen Ziju himself is a very smart person. He can calculate numbers by heart, even up to hundreds plus hundreds. But if it is more, even if he can calculate it, sometimes he will make mistakes. For ordinary people, it is definitely wrong. Now Su Zhi said that she has a way to calculate it easily with a pen, and he really wants to know what the method is. After seeing these poems, he feels that there must be even greater surprises behind.

Su Zhi looked at Shen Ziju and thought that he was really interested in this, so she didn't mind telling him. Spreading knowledge is also a good thing.

"Of course, any number can be calculated."

Xing'er said: "Uncle, we can already be counted within a hundred!"

Yueyue nodded beside her. Although she still made mistakes, she still knew how to calculate!

Xiaori was calmer, but he nodded. He liked to learn what his mother taught him. From what his father and mother said, he knew that only his mother knew how to calculate. No one else knew how to calculate. He thought his mother was the smartest person. Now Shen Ziju had some doubts about Su Zhi's idea, and he wanted to prove it for his mother.

Shen Ziju said, "Fourth sister-in-law, can you let me see how the arithmetic is done? I am very curious and I think it must be very interesting."

Su Zhi said to Xing'er, "Xing'er, ninety-eight plus nineteen, calculate it on the sand table. Show it to your uncle."

Xing'er nodded, wiped the words on the sand table, then took a bamboo stick to write numbers on it and started counting. After just two or three strokes, she got the result.

"Mother, it's one hundred and seventeen."

Shen Ziju looked at the crooked strokes that Xing'er wrote on the sand table. He thought, these are not words. They are not drawings either. They look like some kind of signs. Can you use these to count all the numbers?

Su Zhi then said to Xiao Ri, "Xiao Ri, you count as one too, so let's subtract eighteen from seventy-six."

Xiao Ri responded and started to count on the sand table. He counted just as fast. When he stopped, he got the result. He said, "Mom, it's fifty-eight."

Shen Ziju really believed it this time. These strange strokes could replace an abacus and be used to add and subtract numbers with pen and paper. It was really magical.

"Sister-in-law, what are these curvy strokes? Do they represent the numbers one, two, three, and four? Can you tell me? I think this is a very interesting subject."

Shen Ziju looked at Su Zhi with a strong desire for knowledge. He really wanted to learn this method.

Su Zhi said: "If Fifth Brother is willing to learn, he can learn."

"Thank you, Sister-in-law!"

When Shen Ziju heard that Su Zhi was willing to let him learn, a smile appeared on his face. He bowed deeply to Su Zhi, which was a great bow.

"Fifth brother, what are you doing? Why are you giving such a big gift to your sister-in-law?"

Shen Zian's voice rang out. He had just gone to the bamboo forest to cut bamboo. He had planted some vegetables at home and needed to build a trellis. He was busy there today. He came back when he heard Old Man Lan say that his fifth brother was here. Because he was working, he was wearing a somewhat torn coarse cloth with his sleeves rolled up and two bamboo leaves on his head.

Shen Ziju looked at Shen Zian, looked at his outfit, and then looked at Su Zhi. Although he felt that they were of similar age and appearance, he still felt that his fourth sister-in-law could find a better man. But when he thought that if his fourth sister-in-law was not his fourth sister-in-law, then wouldn't they have no relationship at all? He stopped thinking that way and just thought that it was really God's trick that his fourth sister-in-law met such a strange man and became completely unlike a country girl.

"Brother, I am asking Sister-in-law to teach me arithmetic. I am grateful to her for teaching me. So I will naturally pay you a big tribute."

"That's right. Arithmetic is very useful. It's easy to learn as long as you remember the numbers and the method."

Shen Zian nodded. He knew that his fifth brother was smart and eager to learn. He felt very comfortable that his fifth brother could ask his wife for advice. In fact, this was a kind of pride. In Shen Zian's heart, his wife was smarter than his fifth brother, and that was his pride.

Su Zhi walked up to Shen Zian, raised her hand and took the bamboo leaves from his hair, and said to him, "I've put some water on the table, go wash your hands and face, are you tired? Have a good rest, there's mung bean soup in the kitchen, I added sugar to it, it's not very sweet. How about I bring it out, you and your fifth brother can drink it together?"

Shen Zian nodded and said, "Okay, then you go ahead. I'll wash my hands and face. I'm really thirsty."

Su Zhi went to the kitchen.

"Fifth brother, why did you come here today? Are you feeling well?"

Shen Zian rolled up his sleeves again, and asked Shen Ziju as he did so. Meanwhile, Xiaori came over, wet the cloth in water, dried it, and took it in his hand. Shen Zian washed his hands, and then Xiaori handed the cloth to him, asking him to wipe his face. Shen Zian patted Xiaori's shoulder.

Shen Ziju said, "Brother Lao, please remember that I am fine. It is hot this time, so it is not a big deal if I fall into the water. I haven't been to your place for a long time, so I came here to take a walk, so that we won't be far apart from each other."

Shen Ziju thought about how Su Zhi had just gently taken down the bamboo leaves for Shen Zian, and her gentle questions, and then watched Xiaori so filially hand Shen Zian a towel. He watched Su Zhi come out of the kitchen with a tray. He was really jealous of his fourth brother, thinking that his fourth brother was really lucky to marry a woman like his fourth sister-in-law, and even to pick up three children who were one in a hundred.

Shen Zian walked over and took the tray from Su Zhi, walked into the house, put the mung bean soup on the table, turned around and said to Shen Ziju: "As long as brothers don't do anything really heartbreaking, how can they be far apart? Don't think too much. I saw you looked very uncomfortable after coming out of the water that day, and thought it would be better for you to lie down for a few more days, so as not to miss your study. You also know that your father is still counting on you."

Shen Zian asked Shen Ziju to come in, asked him to sit on the spring-autumn chair, and placed a bowl of mung bean soup in front of him.

"Drink this mung bean soup made by your fourth sister-in-law. It's been too hot these days. It's for cooling off."

The weather now is not the hottest dog days of the year, but it is almost the same as that time, making people feel restless and hot. Almost everyone said that the weather today is different from previous years, saying that this is a sign before the drought. Su Zhi started to boil mung bean soup early for the health of her family, and she boiled it with spiritual spring water. She didn't want anyone to fall ill in this weather.

The three kids sat in a row on the other side. Su Zhi served each of them a bowl and asked them to drink slowly.

Shen Ziju looked at the bowls. The adults used big bowls, and the children used small bowls. They were all black ceramic bowls with a few red plum blossoms on the sides. They were filled with mung bean soup, which looked refreshing. He took a sip and felt a sweet taste flowing into his mouth and involuntarily flowing down his throat. After the first sip, he wanted to drink the second sip. He seemed to be really thirsty. Although he tried his best to drink slowly, he still seemed to drink faster than usual. He didn't put the bowl down until the bottom was empty. He felt as if his whole body was refreshed.

"Sister-in-law Si's cooking is delicious, even this mung bean soup is so delicious."

Shen Ziju's praise was sincere. He admired his fourth sister-in-law from the bottom of his heart and felt that such a woman was exactly the Yan Ruyu he had seen in the books.

It's a pity that Yan Ruyu got married and became his sister-in-law. rq!!! Please remember: (), Wangshuge strives to provide the most refreshing reading experience!
