Chapter 830 Abacus and Mental Arithmetic

Being despised by her own father, Fang Yuan herself was speechless.

While waiting for the children to leave school, he finally figured it out with his fingers, and it took about half a stick of incense.

"It's indeed 620 and three Wen. Those two children are right."

Fang's father frowned, "I didn't expect that there would be such an outstanding child in this rural place. Could it be that he is a math genius?"

Fang Yuan was also quite shocked at first, thinking that he had encountered some kind of extraordinary talent, but later he remembered that this should be the abacus mental arithmetic mentioned in Li Mingyue's letter.

"That's not true, Mingyue mentioned in her letter that the algorithm they used just now should be abacus mental arithmetic.

The so-called abacus mental arithmetic is abacus mental arithmetic.Through the calculation skills and formulas of abacus, people are familiar with and operate the abacus, and describe the shape of the abacus and the floating changes of the beads in the brain, and complete the abacus calculation in the brain through the process of perception and memory.

It is said that this abacus-style mental arithmetic is a very advanced arithmetic, and the speed is astonishingly fast.Often as long as the question is reported, the calculator can blurt out the answer. "

After Fang's father heard it, his eyes suddenly brightened, "There is such a profound arithmetic in the world? Can Miss Li know this abacus-style mental arithmetic? Can it be promoted on a large scale?"

Fang Yuan smiled and nodded, "That's natural, Mingyue is their teacher, and Mingyue taught them this abacus mental arithmetic.

As for large-scale promotion, it should be feasible, after all, the two seven or eight-year-old children just now can learn it. "

"Hey, isn't this our carriage? Why did it stop here?"

The father and son were talking, when Fang Yuan suddenly heard the little boy's voice, which sounded familiar.

He lifted the curtain of the car and looked out, just as Li Mingqing outside the car also looked over.

"Brother Fangyuan!" Li Mingqing exclaimed in surprise.

Li Mingxiang and Li Mingxiu next to him also recognized him, jumping up and down excitedly.

Fang Yuan smiled and carried the three little ones into the carriage, and asked, "Where is your second sister?"

The third one rushed to answer: "Second sister has something to go home, brother Fangyuan, when did you come? You haven't been here for a long time, we miss you."

Not seeing each other for more than a year, these three little kids are still lively and cute, Fang Yuan patted their little heads one by one, and introduced them to Fang's father.

Father Fang nodded to them kindly, and took out the greeting gift he had prepared long ago from his arms.

Under Fang Yuan's gesture, the three little ones obediently accepted and thanked them politely.

Fang's father remembered the abacus-style mental arithmetic just mentioned, and suddenly became interested. He wanted to have a deeper understanding and see if it was really so magical.

"Have you learned abacus and mental arithmetic in school?"

San Xiaozhi nodded, "Yes, I started learning last year, and my second sister taught me."

After getting an affirmative answer, Father Fang asked them a few more questions, whether it was simple addition and subtraction, complex three-digit multiplication, or a mixed operation with multiplication and addition, the three of them almost heard the questions. , you can immediately tell the answer, and the answer is correct.

Although Fang's father felt a little unbelievable, he was more surprised.

He couldn't help asking: "Is it difficult for you to learn this? How long did it take you to learn it?"

Li Mingqing straightened his chest and replied confidently: "It's not difficult at all. I learned it after two or three months."

Li Mingxiang said: "It's not difficult, but it's still a little rare. I've been learning it for five months. And there are a few children in our class who are very stupid, and they can't learn it until now."

From their mouths, Fang's father got the exact data, 42 children studied for a year, only three did not learn.

From this point of view, large-scale promotion should not be difficult.
