"Lian, I've come up with a fun algorithm, do you want to take a look."

When Luan'er entered the classroom and changed careers to become a student, Yang Qiao suddenly remembered a very interesting way of planning the plate.

"Fun algorithms?"

Li Lian was a little puzzled, is this algorithm still fun?

"Well, it's a fun algorithm, what about your abacus, this has to be played with an abacus."

"Come, girl, abacus."

Girl, oh, it's Li Lian's maid, at this time, the daughters-in-law are proud, and one person will be followed by a few maids, some with abacus, some with pencil notebooks, and some with bags.

"Princess, give."

This is the second princess of the Yang family, however, this princess does not have a title, but it is a real princess, the emperor's daughter, not what a princess is, it's just that there is no title, there is no imperial grain, you know, the women with titles in the family all have imperial grain, but what is this imperial grain, such as, the income of a township, the income of a county or something, and Luan'er, just enjoy the income of a county, which was actually reduced by Li Er.

However, although Li Lian is not titled, if people call the princess, who dares to have an opinion, or who will have an opinion?

"Husband!"

Li Lian gave the abacus to Yang Qiao.

This abacus is not so precious, ordinary wooden frames, ordinary sliding rods, ordinary wooden beads, and even, there is no lacquer, this is why, the daughters-in-law are in a hurry, they all want to see good things, especially, this abacus, used to calculate, is so simple, just fiddle with a few times, a fairly large number, it is calculated, you know, at this time, some things of the Yang family are calculated, but it is more complicated.

The so-called complicated, but the currency at this time is a little simple, all use copper coins as currency, then, this article, a piece of calculation, is naturally complicated, especially this valuable thing, if it is used as a unit, hehe, hehe, with the calculation, there is really no way to say.

Therefore, when Yang Qiaoyi showed such an ugly abacus, yes, counting the ugliness, the primary color wood, naturally, this pattern was messy, and the wood was not the same, it was even more messy.

This, what do you say, Yang Qiao wants to do it well, but the daughters-in-law are reluctant to use it in their hands, no, they just use it, and Yang Qiao promised Luan'er to do it, naturally decided to choose a good wood, and even inlaid with gold and silver to decorate.

"Come, Lian, sit, let me call you, this way of playing is called the lonely goose out of the nest."

As he spoke, Yang Qiao took the abacus and shook it, the upward and downward directions, and the beads on both sides were in place.

"Husband, you are, there is this way, why don't you teach us?"

"Well, this, I'm not afraid that you will not be fine, so I didn't teach you this method."

"Well, well, I forgive you, other sisters, I can't say, but I learned it first, hehe, hehe!"

Well, how do you feel, this laughter, it's schadenfrefreude laughter.

Why do you feel a little bad, it is estimated that kneeling on the washboard is impossible, and it is still possible to grind the needle with an iron rod, oh my God, when will it grind to the end!

"Hehe, boy, I'm sighing again, right, tell me, I almost died, but what do you mean by this lonely goose coming out of the nest here, since you know, why torture me, let me die, down, I'm dead, down, what's the good for you."

Yes, this is not a person looking for a post-account, and this tuberculosis has followed.

"It's your incompetence, I'm no longer self-reliant, how can I show off this plan."

"So, you're here to show off?"

"Alas, I don't understand to you, wait a minute, I'll explain."

"Lian, look, what about this, I'm going to beat a lonely goose out of the nest, this thing, what's the use, is to verify whether your abacus is accurate, and you can't make mistakes, but, to say that it's simple to play back and forth over and over again, it's a bit boring, so I came up with such a way, but I can only come up with such a way, and you haven't learned it, and you, today, it's the first time you've seen it, or it's the first time you've seen it in this world."

Yang Qiao began to move his hands while explaining.

First of all, come a nine-nine-nine-nine-nine, put it on the right, and then, come to another nine-nine-nine-nine on the left, and this way of playing, is multiplication, multiplication formula, remember, yes, that's it, this formula, and abacus formula, there are still some differences, this ninety-nine-eighty-one, you see, this is a ......

"Husband, is this a lonely goose out of the nest?"

Looking at the numbers on this abacus?

"This thing, how to say it, you see, isn't this a lonely goose, it's just one, and then, from this side, down to this side, isn't it, the lonely goose, out of the nest, isn't this a lonely goose out of the nest, but, you give another name, it's also become, it's a thing that you will, if you say, really as a swallow, that's impossible, this is a bunch of wooden beads arranged in a regular way, can it become a swallow, and this way of playing, is to let you verify how your multiplication abacus plays, naturally, and addition, Subtraction or something, come on, you try. ”

"Oh!"

Li Lian seemed to understand whether she understood or not, and she also learned from Yang Qiao to throw the abacus.

"Husband, why can't I get rid of the way you dumped it, this, I still have to use my hands."

"Let's do this first, this, there must be a skilled process, do you know why I didn't do it before, this is also what I secretly practiced."

"Ahh

Explained like this, Li Lian understood a little, secretly practiced, in this way, it is the correct solution, no matter how talented the husband is, he will not know everything at once, that, you think too much, which, not Yang Qiao will know, it is not at once, it can be said that most of them are.

"Hehe, talker, why this time, there should be a task or something, but you didn't move?"

"Hehe, it's not that there is no movement, but there is no such record in me or the system, how can you let me have movement!"

This, weird, weird, Yang Qiao was a little depressed, in his previous life, this thing, should have been published in books, but, why is this tuberculosis, ah no, there is no record in the system, you know, this tuberculosis, but there are records of five thousand years up and down, why, there is no such record, but, this thing, indeed, should exist, it is said that at that time, it was widely circulated among some accounting and custody, naturally, this accounting, large, to what high-level unit, small, to the accounting of several people's units,Custody,As long as there is this profession,They can copy each other,Ah,Yes,This is actually hand-copied,Is it,Because of this,Sure enough,In the chatterbox,In addition to the unearthed cultural relics,There are plagiarized,No,Manuscripts,For example,What four books and five classics in the Tang Dynasty A certain hand-copied remnant or something,Even,Even what terracotta warriors,It is also explained that it was found in 19 A.D.,Again,There is no historical record,Sure enough,This is a,You can't make things out of thin air,You can't put some things into words,Oh, It was fabricated by the public writing system.

That is to say, the things in the tuberculosis system are all recorded from what, the interstellar library, what the medieval first picture or something, what the English picture or something, and even, it must be entered into electronic text, or in the form of pictures, that is, the books that have not formed electronic products, no matter how widely circulated, this tuberculosis system will not be recorded.

"Husband, I'm here, I don't feel like a lonely goose is out of the nest, but two birds have flown together."

"Well, you're making a mistake, that's why you use this exercise, no, you can see it at a glance, since the lonely goose has become a double bird, it's not wrong, what is it?"

………………

"That's how abacus is used, well, I see, the beads of the two above, one represents five, and the beads of the five below, one represents one, I have always thought that this is a joke."

Playing, playing, you actually made this abacus so exquisite, and even the beads are made of jade.

The eldest grandson listened to Li Er's ridicule on the side, and pouted a little, you know, for this abacus, Li Er is fine, so he studied it with the eldest grandson, but he just couldn't study it, what do these seven beads mean, how to calculate it, but, if you want to say it's playing, people calculate it very quickly.

Indeed, Li Er has been looking at this abacus for a long time, but the secret guard, even if he steals the abacus, he can't study anything, at most, some of them are marked with something ten hundred million or something, so they were all stolen that night, and they were sent back that night, because they were afraid that Yang Qiao would get angry.

Stealing, naturally, sometimes, daughters-in-law will live in their own property, then, this abacus is not strictly defended, in fact, there is nothing to defend, this thing, it seems simple, but, if there is no explanation, use, but it is very complicated.
