In fact, in later generations, this addition and subtraction of hundreds of children is just the most basic part of practicing abacus.
To add a hundred sons is to add from one plus two to three plus four...all the way to one hundred. To subtract a hundred sons is to go from one hundred to ninety-nine to ninety-eight...all the way to one.
The result of adding Baizi is five thousand and fifty. And the result of subtracting Baizi is zero, and the board is empty in the end.
As long as one calculation is wrong or omitted, the correct result will not be obtained.
Although Xiao Wan'er had watched her mother beat her several times, she still watched with concentration.
As soon as her mother finished the calculation, she clapped her hands happily on the sidelines: "Mom is so awesome! Mom wants to teach Wan'er! Wan'er also wants to learn."
"Okay, Mommy will teach Wan'er everything."
Qiao Mingjin glanced at her daughter with a smile, then moved it to Wang Accountant's face and asked, "Has Accountant Wang seen the benefits of this abacus?"
The accountant Wang picked up the abacus and looked at it again, pressed the liquidator several times with his left hand, and did some calculations of addition and subtraction in front of Qiao Mingjin.
It's just that the speed is significantly slower.
But the king's accountant seemed very happy.
"Hahaha, much faster than I usually do!"
After saying that, there was a smile on his face.
Qiao Mingjin looked at the cashier in front of him who was eager to try, and felt somewhat relieved.
There is nothing more satisfying than having your things recognized by others.
Seeing that the king's accountant was happy, Qiao Mingjin asked directly: "Is the king's accountant going to give me a hand?"
After hearing this, Wang Zhang glanced at Qiao Mingjin, with a smile on his lips, and asked: "How much do you plan to sell a handful of it, little lady?"
Qiao Mingjin thought for a while and then said: "One tael of silver per handful."
Qiao Mingjin originally planned to catch the fat sheep and slaughter them. But seeing that the king's accountant didn't look like those shrewd and cunning people, after thinking about it, he had no choice but to forget it.
This price is a price negotiated with several brothers and sisters. Under normal circumstances, it cannot be lower than this amount.
The smile on Na Wang's lips became even deeper.
He smiled and said: "Although your abacus is not sophisticated, but for you as a liquidator, the abacus is more than one or two."
Seeing Qiao Mingjin looking a little regretful, I felt that this little lady was funny. She was courageous but not ruthless enough.
Then he said: "I wonder what I call the little lady? How many calculations do you have?"
Qiao Mingjin then replied: "The little lady's surname is Qiao. There are some other abacuses like this, and many have been made at home. As you can see, although these ideas are excellent, they are also very easy for others to imitate. So the little lady's family has many
I have made some, and today is the first time I sell them. This is your first time."
The king's accountant glanced at the woman in front of him very strangely.
Most women would introduce their husband's surname, but this young lady only mentioned her maiden name.
Wang Zhangfang glanced at the little girl who was sitting quietly aside, and seemed to understand a little.
I'm afraid that there is something wrong with this woman's family, or her husband has died, or something like that. Otherwise, why would she show up with such a young child to sell things?
I can't help but feel some sympathy.
After thinking for a while, he said: "There are twelve people in our house, both inside and outside. I am the general manager. Just give one of us a hand. In addition, we also have various shops and Zhuangzi's counting houses in the house, but
This will have to wait until I report it to our master before I can make the decision. You can come back tomorrow at this time to listen to me, or you can tell me where you will rest. I sent a boy to look for you."
Qiao Mingjin was very happy after hearing this.
He hurriedly said: "The little lady lives far away, in the village below Songshanji. If I can't go back tonight, I may stay in the city for the night, and there is no fixed place. The little lady will definitely come to the house tomorrow to listen to my message.
Thank you, Accountant Wang, thank you very much!"
Xiao Wan'er also slid off the stool and followed her mother's example and bowed to the king's tent.
The king's accountant felt bitter and happy at the same time.
It seems that the mother and daughter don't even know how to salute.
He smiled and didn't care.
Qiao Mingjin thanked him, and after thinking about it, he took out a palm-sized abacus from his pocket and said to Wang's accountant: "Manager Wang, take a look, do you need this small abacus?"
Manager Wang never thought that Mrs. Qiao could think of making such a small and more portable abacus.
I took it in my hand and tried it, and I thought it was pretty good.
Although it is small, it is not like today's abacus where you have to move the beads very carefully to avoid getting beads. Because the beads are changed into a diamond shape, the probability of making mistakes is avoided. The weight is also very light, and it can also be used as a dish cleaner.
Manager Wang smiled and nodded: "Well, this is very good. I want a handful. How much silver does this cost?"
Qiao Mingjin also saw that Manager Wang was a real person, so he said: "I made this little abacus exquisitely. I planned to sell it for five taels of silver. If you want it, just give me three taels."
Manager Wang smiled and his impression of Qiao Mingjin became better.
After touching Xiao Wan'er's head, he took out a fifty-tael banknote and handed it to Qiao Mingjin.
Said: "I want three handfuls of this little abacus. I'll take this one away, and you can bring two more tomorrow. If I still want it, I'll tell you tomorrow when you come to listen."
Qiao Mingjin took the bank note and looked at it carefully.
The king's accountant was not surprised at all when he saw it.
It's not surprising that Mrs. Qiao can make good calculations and knows a few words.
I just don’t know which family the girl is from? She looks like she comes from a farmer’s family, but she doesn’t look like it. She is a well-educated woman, and she also knows how to handle things neatly. She also knows how to be polite. Although her manners are weird, her eyes are clear.
Neither humble nor arrogant.
Did he come from a poor family?
The king's accountant just had it in his heart, so he didn't worry about it.
Seeing the joy on the faces of these two women, I felt very good in my heart.
Qiao Mingjin looked at it carefully and pushed the bank note back and said, "The little lady can't find it."
Manager Wang smiled and said, "This is the money for you to give you three small abacus and twelve large abacus. If you order again tomorrow, we will calculate the money separately. Your abacus is worth this price."
After saying this, he greeted the mother and daughter and walked straight into the house.
Qiao Mingjin bowed behind him. It was rare to meet such a talkative person for the first time.
When the mother and daughter said goodbye, Qiao Mingjin grabbed a handful of copper coins from her bag and stuffed them into the hands of the two boys, thanked them, and left with Xiao Wan'er.
Next, she followed the same pattern and went to ten more houses in succession. People were notified at the door of each house, specifically looking for the accounting room.
In fact, you may not be able to find someone if you look for someone else. But you can usually find someone if you look for a bookkeeper.
Very few tents are clean.
If you want to put things to rest, you have to come out and meet.
Of course, some people think it's expensive. They say the wood is not good, it's just ordinary wood and not worth a tael of silver.
There were also some people who held it in their hands and looked at it carefully. But Qiao Mingjin didn't give them many opportunities to observe.
She hasn't even made her first pot of gold yet, how can she let others rush to learn it so quickly?
There was also an accountant in the mansion. After seeing Qiao Mingjin's abacus, he asked the servant to call a young accountant out and asked her to compare the abacus with the accountant to see who could calculate accurately and quickly.
, just buy her abacus.
He also said that if Qiao Mingjin won, he would help each of the cashiers in the mansion buy a handful. In addition, each of the major shops in the mansion and the cashiers in each village would be equipped with a handful. There would be a total of sixty handfuls.
Big ones. Thirty smaller ones. It just depends on whether Qiao Mingjin has the ability.
Qiao Mingjin's temperament is not the kind of person who gets hot-headed when provoked. But this is obviously related to Yinzi. Nowadays, Yinzi is the biggest in the world. How can he be at odds with Yinzi?
Not to be outdone, Qiao Mingjin agreed without thinking. How could she bow her head in front of these ancients?
She also made a condition. If she wins, the abacus will be raised from two taels of silver to five taels! The small abacus will be raised from five taels to ten taels! And it must be written down in black and white.
The accounting room of Xie Mansion immediately became commotion.
Even their old man who was idle at home came out to watch the fun.
The old Mr.
Later, when I got rich, I saw people who were good at accounting and calculation, and they would try their best to recruit them into the house.
Therefore, several accounting offices in their family are very powerful. There is no need to look at the paper. Someone is holding the paper and reading next to it, and the accounting office will move the beads on the abacus. Then after others finish reading, the accounting office that dials the abacus will also calculate the results.
Already.
The old man from the Xie Mansion proposed this method of competition.
He also added that if Qiao Mingjin wins, he will not only buy her sixty large abacus and thirty small abacus as written on the paper, but also double this number!
All the young masters and ladies in their family had a handful of them, and the ones that had more were given to the children of relatives.
And there is an additional bonus of one hundred taels. Whoever wins gets it.
This caused more than a dozen accountants in the Xie Mansion to compete with Qiao Mingjin.
What a joke, how can a little lady from the countryside compare to people like them who are immersed in this practice every day?
One hundred taels of silver! Who doesn’t want to take it?
In the end, Mr. Xie recommended a young man who was recognized as a fast and accurate abacus to compete with Qiao Mingjin.
Another middle-aged accountant was chosen to stand aside and read numbers.
At that time, Qiao Mingjin only had a large abacus and a small abacus in her bag. She took them out and put them on the table.
After the old man Xie said it was time to start, Qiao Mingjin started moving with both hands at the same time. After clearing the plate, she moved her left and right hands together, flying so fast that people couldn't see her movements clearly.
Everyone present was stunned.
The old accountant who was reading the numbers at the side stayed where he was and almost couldn't stop reading.
It’s a joke. In my previous life, in order to practice abacus, I practiced with a tape recorder for who knows how many years.
As soon as the voice on the tape recorder started, Qiao Mingjin started typing. After the soft girl on the tape recorder finished reading, Qiao Mingjin's results also came out.
Wait for the female voice to say "equal to..."
Qiao Mingjin didn't even need to look at the board, the answers she typed were all imprinted in her mind.
When the answer was read out on the tape recorder and her result was accurate, she followed it up. Before the next question was read out on the tape recorder, she was ready to go and could squint her eyes and rest for a while.
Besides, what’s so strange about two abacuses playing at the same time?
This is the basics, right? It's just that when practicing the basics, you practice with both hands on an abacus at the same time, dividing the left and right halves.
But when two abacus are used together, Qiao Mingjin also practices it, which can save a lot of time.
Qiao Mingjin looked at the dumbfounded look of a group of people and laughed happily.
ps:
Thanks to sh for pointing out the error. I didn't notice the problem of hexadecimal calculation in ancient times, so I still used decimal for the abacus, making one bead on the upper beam and four beads on the lower beam. I apologize to you all. The previous chapters have been revised. Thanks to "sh" and everyone who gave valuable opinions. Thanks to "197067, 3ao1234" for voting pink, and thanks to "Leilei 313" for voting two pinks. Thanks to "Master Junao". A safe talisman for the reward.
