Listening to Mao Xiang's explanation, Hu Changan also couldn't laugh or cry.
No wonder these Jin Yiwei looked at him strangely before, as they regarded him as a dancing master.
Hu Changan took a sip of water and said with a smile: "Everyone, I use a type of characters called Arabic numerals and an arithmetic method called four arithmetic operations."
"As long as you learn my method, you can read accounts as fast as me."
When everyone heard this, they were all excited.
Unexpectedly, this is not a divination method, but a new arithmetic method!
Originally, they had some resistance to the method of divination.
But they have no objection to arithmetic methods at all.
Everyone looked at Hu Changan, eager to try.
They also want to learn these magical Arabic numerals and four arithmetic as soon as possible, so as to quickly get involved in the investigation work!
Looking at the shining eyes of everyone, Hu Changan also smiled slightly, picked up the slate beside him, and explained to everyone.
These Jin Yiwei are all smart people and have mastered basic arithmetic knowledge.
Soon, they mastered the Arabic numerals and the four arithmetic algorithms.
Everyone was excited to experiment with this novel arithmetic method.
This is much faster than their previous calculations!
The counting method is to use small sticks to represent the numbers from one to ten, and place them in different shapes on the table for calculation.
When calculating with arithmetic chips before, it would take half a day just to arrange the arithmetic chips correctly.
Moreover, this calculation also takes up a lot of space. One calculation often takes up an entire table.
More importantly, if this calculation is tilted at a different angle, it means completely different things.
Therefore, when calculating with chips, everyone must be nervous to see if anyone is passing by.
After all, if someone passing by accidentally messes up the calculation, the calculation they took a long time to arrange will be in vain!
The use of arithmetic calculations is also a very important reason for the slowness of auditing accounts.
After all, it takes half a day to do the simplest addition operation. How can the speed of checking accounts be so fast?
But these four operations are different.
These four arithmetic operations do not require any auxiliary tools at all.
With just a slate and a piece of charcoal, you can perform calculations at any time and anywhere.
In less than a minute, they can complete calculations that originally took ten or even twenty minutes to complete.
This is simply a miracle!
And the Arabic numerals are also quite magical.
Originally, it would take them at least a few minutes to write a number.
After all, numbers are also Chinese characters. How can I write faster with a brush?
But the Arabic numerals are different.
With just one stroke, a number is formed.
In one minute, they can write at least ten Arabic numerals!
This efficiency is definitely more than doubled!
Everyone was in admiration for Hu Changan.
I don’t know what kind of outstanding brain can come up with such a simple algorithm!
Hu Changan looked at the fiery eyes of everyone and smiled slightly.
These four arithmetic operations and Arabic numerals are the culmination of the wisdom of mathematicians at home and abroad, both ancient and modern!
Everyone has used it and said it is good!
At this time, everyone was simply full of confidence.
With this magical algorithm, they will definitely be able to exceed Zhu Yuanzhang's mission!
However, at this time, someone raised a new question: "Shilang Hu, I wonder how to identify this fake account?"
After everyone heard this, they all turned their attention to Hu Changan.
Yes, what Hu Changan got this time happened to be the real account.
But what should you do if you get a false account?
Those who make false accounts will not speak out and say that they are false accounts.
Distinguishing real accounts from fake accounts requires years of accounting experience.
What should these people who are halfway to become monks do?
However, when Hu Changan heard this, he just smiled slightly and said: "No problem, it's easy to handle. I happen to know a simple way to distinguish real accounts from fake ones."
"In real accounts, the probability that the first digit is 123 is about 60%."
"In the fake accounts, the probability that the first digit is 123 is significantly lower than 60%."
"As long as you check the account books one by one according to this rule, you will be able to find false accounts among the true accounts."
Everyone was stunned when they heard this.
This... what kind of rule is this?
This is simply child's play!
An impatient Jin Yiwei stood up first: "Shilang Hu, although your Arabic numerals and four arithmetic algorithms are very magical, you can't just use weird things to deceive us!"
"In my life, I have never heard that one can judge whether a real account is a fake one just based on the first digit in the account book."
"This is simply unheard of! I don't care whether others believe it or not, I don't believe it anyway."
The Jin Yiwei's words immediately gained support from many people.
Even the commander of the Jinyi Guards, Mao Xiang, frowned and looked at Hu Changan.
It is true that Mao Xiang thinks Hu Changan's method just now is very good, but the method Hu Changan proposes now is just like a dancing master.
Logically, this makes no sense at all!
As a person who has always been rigorous, Mao Xiang strongly disagreed with Hu Changan's approach of speaking out.
However, despite everyone's disapproving looks, Hu Changan smiled slightly and said: "Whether you can understand it or not, there is indeed such a pattern in the world."
"If you don't believe it, you can make up a few accounts on the spot and mix them with the real accounts and show them to me."
"I bet I can find fake accounts among them!"
"It won't take you much time anyway."
"Once this conjecture is verified, you will definitely save more time!"
Hu Changan knew that these Jinyi guards would not believe him unless they saw it with their own eyes.
After all, this matter does seem logically strange.
The person who invented this conclusion finally came to this conclusion through a large amount of evidence and repeated arguments.
When everyone heard this, they were all skeptical.
This matter is indeed a bit outrageous to them.
No one can believe that such a weird thing exists.
But secretly, they couldn't help but want to believe Hu Changan.
Based on what Hu Changan just took out, Hu Changan can definitely be called the master of arithmetic in the world.
Hu Changan said so confidently that they couldn't help but be a little shaken.
Could this be true?
After a while, Mao Xiang finally made the final decision: "In that case, then you can go and compile three account books on site and mix them into the ten real accounts."
"Let me see if Mr. Hu can pick out these three false accounts!"
Mao Xiang wanted to see if what Hu Changan said was true. This chapter has been completed!
