Just getting in touch with new things, people are excited, in the afternoon, the old Luo family and a large family gathered together to learn formulas, and even Wang Guihua and several women who said they didn't learn before also stayed.

"Alright, alright, it's time to study for the afternoon, let's rest, let's go prepare dinner." Wang Guihua said.

"Yes, yes, rest, rest, I'm dying of thirst." Luo Jiashu got up from the edge of the kang, walked to the stove, scooped the water in the jar with a scoop, and was about to drink it directly.

"Second brother, I said that you can't drink raw water directly." Luo Qinghe went out and saw it, and hurriedly stopped it.

Luo Jiashu's pouring action suddenly stopped, and then looked at Luo Qinghe with a face full of grievances, "Thirsty." ”

Luo Qinghe smiled, "Isn't the boiling water in that jar on the stove cold?" ”

"Forget." Luo Jiashu laughed, put the scoop on the stove, picked up the jar, poured water into the scoop, and then drank the water satisfied, "The taste is not bad, Qinghe, is it necessary to be so troublesome, the water is hot, and you can drink it when it is cool." ”

"Yes." Luo Qinghe's words were concise and to the point.

"The little girl's family has a lot of things." Luo Jiashu muttered.

"Second brother, I heard it." Luo Qinghe said with a smile.

Luo Jiashu grinned, "Hey, look, I'll be quieter next time?" ”

Luo Qinghe laughed out loud, glared at Luo Jiashu and went into the house.

"Milk, what do you eat at night, cornmeal gnocchi soup or cornmeal paste?" Luo Jiashu asked loudly after quenching his thirst.

"Let's go farther, we'll wait for some water." Wang Guihua took the scoop in Luo Jiashu's hand and said, "Have this leisure, go and remember the mantra of Qinghejiao, see how old people are Qinghe, you will understand so much, and then look at you, worry about food and interest all day long." ”

"Milk, then I'll go memorize the mantra." Luo Jiashu turned around and went back to the house.

Wang Guihua was stunned, this kid is not as usual, is his words serious? No, it's always been like this.

"Milk, let's eat tortillas, the one who carries hunger and drinks soup and water will be hungry at night." Luo Jiashu turned around before entering the house and looked at Wang Guihua expectantly.

"Okay, I'll stick the cake."

"Milk, that's great." Luo Jiashu happily rushed over and hugged Wang Guihua, and then rushed into the house.

Wang Guihua also smiled, this kid, really.

"Mother, what's the good thing about that dish? Wild vegetable soup? Liu Lan asked.

"Give Jiadi's daughter-in-law a whole pig's trotter soup, and then take a few pieces of pig's trotters from her, and cook a pot of wild vegetable soup for everyone, with more oil and water; Then go to the vegetable garden to pick a few lettuce, I have seen some of them in the past few days, fried and eaten with a dish, and eat better tonight. Wang Guihua said with a smile.

"Okay, mother." Liu Lan also smiled when she heard this, the meals of these two days are really in time for the New Year, and she didn't wake up hungry for the first time in the middle of the night last night, such a day is really happy.

Luo Yougen, Luo Jiashu and others were still memorizing formulas in the house.

"Qinghe, the white-faced question that the second brother asked you before, how did you calculate two hundred and eighty at once, I see that there are only three eight twenty-four, five eight forty, do you want to use the column method you said?" Luo Jiashu approached Luo Qinghe and asked shamelessly.

"Yes." Luo Qinghe nodded, then looked at Luo Jiashu and asked, "Second brother thinks that you need to use this multiplication method to calculate that white face problem?" ”

"Isn't it?" Luo Jiashu was puzzled, "What kind of addition are you talking about, one pound of white noodles and eight words, a full thirty-five pounds, when will this be added, how can it be calculated all at once, so I think you should have used this multiplication, am I right?" ”

Luo Qinghe nodded appreciatively, "The second brother has a good mind, just use multiplication, you see I will show you the column formula." ”

Luo Qinghe picked up the charcoal, wrote 35 and 8 vertically on the wooden board, 8 and 5 aligned, "Second brother, you see that 35 is two numbers, 8 is a number, the same number is aligned like this, you remember to align ...... right"

"Digital, what's that?" Luo Jiashu interrupted and asked.

For people who have a thirst for knowledge, Luo Qinghe never hesitates to explain, "pop" and write down four numbers, "from right to left, this is called a single digit, this is called ten, this is called a hundred, this is called a thousand, and then there are ten thousand, one hundred thousand...... You can memorize the first four digits first, and generally the latter ones are not used much. ”

"Then the number at the bottom is this 8, multiply by 5 and 3 respectively, because you have to multiply from a single digit, that is, multiply from right to left, multiply to which digit you will write the result below which digit corresponds, if the number obtained is two digits, the corresponding digits remain unchanged, and the more digits will be written forward." Luo Qinghe explained, while the charcoal under his hand kept stopping, "Five, eight, forty, 0 and 5 are aligned, and 4 is placed one in front; Then three-eight-twenty-four, 4 and 3 are aligned, and 2 is placed one place forward. The end result is to add up the above gains. ”

"Multiplication is more difficult, not only to multiply, but also to add." Luo Qinghe continued, "If the single digit is 0, it will be copied directly, the ten digits are 4 plus 4 to get 8, and the hundred digits are 2, and the final result is 280, two hundred and eighty texts. ”

Luo Jiashu was dumbfounded, "Qinghe, you are much faster than the bookkeeper of that shop, what kind of formula, column formula is so amazing, it is too powerful, I must study hard." ”

Luo Yougen also listened on the side, also incredulous, and after thinking for a while, he asked, "Qinghe, are there a lot of numbers, what you teach us now is 0 to 10, is this how eleven is written 11, and is one hundred and eleven 111." ”

"It's the same as the number you just said, in fact, the number is 0 to 9 ten styles, where is this number, and the name of the number should be added to the back when you pronounce it? Is that the solution is solved in this way no matter what number is multiplied? ”

Now it was Luo Qinghe's turn to be surprised, obediently, Xueba, just like that, people not only understand, but also draw inferences, "Uncle, you are so smart." ”

Luo Yougen was stunned for a moment, and no one had ever praised him so bluntly, "I'm not as good as Qinghe, it's you who teach well, you're only so old, not only are you an excellent female celebrity, but you're also good at reading and literacy, I didn't expect that arithmetic is so powerful, and my uncle is ashamed of himself." ”

"Haha, haha, uncle, you practice more." Luo Qinghe didn't know what to say, so he could only turn the topic away so awkwardly.

She, a person who has been in school for sixteen years, is not as good as a young man who is only fifteen years old now, so she is really going back more and more.

"Qinghe, then if today is not a catty of eight Wen, but eighteen Wen, then this eight is still according to the previous one, what about this one, is it, also multiplied by the above two numbers, and the last two are added?" Luo Yougen asked in a low voice.
