Qin Yu and Xiao Nan originally planned to go to the east palace side hall to rest.
But when he was halfway there, he was stopped by a petty official, "In this humble position, please see the Prince Consort, His Royal Highness, Miss Shen."
Qin Yu nodded, "Is something wrong?"
The clerk responded: "Qin Shangshu said that the Ministry of Revenue is already a little busy. If the Prince Consort is not busy, he can go to the Ministry of Revenue to help and do whatever he can."
Qin Yu: "...."
Do something within your power?
Qin Yu felt a headache. He really didn't want to go. He just wanted to enjoy life.
"Brother-in-law, I just remembered that I have something to do over there..."
Xiao Nan said, turned around and left.
"Eh~"
Qin Yu caught Xiao Nan at once, "You are so good at arithmetic. It would be a pity if you didn't go to the household department to help. Let's go together... .”
As he said that, he looked at the clerk and said, "Lead the way."
Then, under the leadership of the petty officials, everyone went to the Ministry of Household Affairs.
Xiao Nan said with a sad face, "Brother-in-law, something really happened to me."
Qin Yu said calmly: "Come on, you just went to the side hall to listen to music and you were still free. What happened so soon?"
Xiao Nan had no choice but to follow Qin Yu to the household department.
During the year-end period, the household department is the busiest.
Xiao Nan knew that this entrance area was as deep as the sea.
.......
Royal Palace.
Household Department.
From Qin Wenyao, the Minister of Household Affairs, to officials at all levels, everyone was busy coming in and out.
Qin Yu and Xiao Nan also felt nervous after entering the household department.
The atmosphere is like going to a battlefield.
"I have met His Highness the Crown Prince."
Qin Wenyao looked at Qin Yu and Xiao Nan and walked over.
Xiao Nan smiled hurriedly, "Master Qin, as soon as I heard that the household department was busy, I hurried here with my brother-in-law. If you have any work, just assign it to us."
Qin Yu: "......"
He felt that Xiao Nan now understood the world.
He was about to run just now, but now he took the initiative, looking righteous and awe-inspiring.
Qin Wenyao laughed and said: "Your Highness, your awareness is really getting higher and higher."
As he said that, he looked at Lu Tai, a doctor from the Ministry of Finance, and said, "Find a place for the consort and the prince, and assign them some tasks."
Lu Tai saluted and said: "I accept my order from my humble position."
Then, he led Qin Yu, Xiao Nan and Shen Binglan to a corner, and then gave them the tax account books of Funing County, Hebei Province, which were piled on two desks.
"Holy shit!"
Xiao Nan looked at the pile of account books that were as big as a hill, and he complained in a low voice: "Isn't this... too many?"
Qin Yu glanced at him and said in a deep voice: "Didn't you just say that I would just assign you any work? It's too much now."
Xiao Nan said with a smile: "Hey~ Didn't I sell it in front of Mr. Qin just now? Who would have thought that Mr. Qin would take it seriously."
As he spoke, he picked up an account book and flipped through it, "Brother-in-law, where do we start checking?"
Qin Yu also picked it up. It was full of characters, and there were no simple numbers. They were all capital numbers such as one, two, three, four, and five.
Qin Yu felt a headache as he watched.
Not to mention these capital numbers, it is dazzling to even look at them, and you may make mistakes if you are not careful.
No wonder the calculation efficiency of the household department is so low. The main thing is to rely on one person to make more calculations.
Xiao Nan also felt a headache and couldn't figure out what to do. Then he looked at Qin Yu and said, "Brother-in-law, you have the most ideas. You should find a way to come up with it!"
Qin Yu looked at Xiao Nan and said thoughtfully: "Do you want to learn something different?"
Xiao Nan was stunned and asked curiously: "What's different?"
Qin Yu muttered: "Simple numbers."
"Easy numbers?"
Xiao Nan looked confused, "Then...what is that?"
Qin Yu had no words and just wrote numbers from 1-10 on the paper.
Xiao Nan looked confused.
Shen Binglan stood aside and watched, with confusion on her face.
None of them understood what Qin Yu wrote and what it meant.
I saw the confusion on both of their faces.
Qin Yu explained: "This one corresponds to 1, this two corresponds to 2, and this three corresponds to 3..."
In fact, the simple numbers he refers to are Arabic numerals.
The advantages of Arabic numerals are self-evident. Only a few numerical symbols are needed to express all natural numbers. They are concise and clear, easy to calculate, and easy to understand.
Listen to Qin Yu's explanation.
Xiao Nan and Shen Binglan gradually understood and were surprised at the same time.
Qin Yu actually created a whole set of numerical symbols with just a few movements of his hands?
this......
This is simply a fantasy and appalling.
"Brother-in-law."
Xiao Nan looked at Qin Yu blankly, "This... you just researched this?"
Qin Yu said lightly: "Otherwise? Isn't it much easier if you use these simple numbers to replace the original numbers and then calculate again? And the accuracy is very high."
Listen to Qin Yu's words.
Xiao Nan freed up two lines of numbers, then scanned them with his naked eyes, and the results came out instantly.
It's much faster than him looking at the uppercase numbers directly.
"Oh my God!"
Xiao Nan couldn't help but feel a sense of exclamation, "This... this calculation is really much simpler!"
He really didn't expect that Qin Yu's talent would be put to use no matter where he was.
Shen Binglan raised her eyebrows. She did not expect that Qin Yu could come up with such a method that was almost cheating even in arithmetic.
The benefits of simple numbers will be more fully reflected as the amount of calculation increases.
Qin Yu said calmly: "We have to replace all these uppercase numbers with simple numbers."
Xiao Nan looked at the account books on the two tables and said in surprise: "This... when will this have to be replaced?"
Qin Yu muttered: "The sharpening of the sword will not waste the time of chopping wood. Even so, our efficiency will be greatly improved."
As he said that, he glanced aside and said, "Now that I'm talking about it, we don't have to replace it ourselves. We can just find two clerks."
Afterwards, Qin Yu asked Lu Tai to find two clerks and taught them simple numbers.
After hearing this, the clerk was also shocked.
The Prince Consort is truly unparalleled in the world, he can do anything with some tricks.
Immediately afterwards.
Qin Yu and others began to divide the work and cooperate, and the two clerks replaced the uppercase numbers with simple numbers.
Xiao Nan is responsible for oral calculation.
Shen Binglan is responsible for the summary.
Qin Yu is responsible for... responsible for catching fish.
There is no way, after all, the numbers developed by Qin Yu have greatly improved the calculation efficiency.
He is qualified to fish.
