Daqin started with offering immortal medicine

The advance payment of money and food by the commercial bank is directly related to the current survival of the victims in the city, because at this time, the people in the city can be said to starve to death every day.

Li Yang got the statistical data on the number of labor applicants, and went directly to the person in charge of Bashi Trading Company, saying: "This is the statistical data on the number of laborers who can be recruited in Pei County. Let's see how much food is still short, and send it over as soon as possible."

The person in charge of the firm took the labor data, then lay down on the stone steps at the entrance of the yamen, and began to calculate.

And Li Yang was waiting beside him.

In the end, after waiting, Li Yang was really dumbfounded!

I saw that the man from the business took a small bag from his waist, and then poured out a bundle of small bamboo sticks from the bag. Each bamboo stick was ten centimeters long, and a bundle was at least one or two hundred sticks.

While comparing the labor data, he began to place the bamboo sticks on the steps one by one, and then began to calculate slowly...

Li Yang was shocked immediately, is this an ancient mathematical operation?

Oh my god, if you count this way, you have to count to the year of the monkey?

Sure enough, after waiting for nearly a quarter of an hour, the other party calculated the number of workers who had not paid in advance.

That is to say, the total number of labor applicants minus the number of laborers who have already paid in advance, this five-digit subtraction, took the other party more than ten minutes to calculate.

Li Yang was dumbfounded.

Now, he finally realized how cumbersome and time-consuming mathematical calculations were during this period.

A five-digit subtraction is actually so time-consuming to calculate. Li Yang really can't imagine how much manpower and time they need to calculate the entry and exit accounts of a country's finances.

However, Li Yang also knows the other party's calculation method, which is called calculation.

Counting is one of the calculation methods in ancient China. It began around the Spring and Autumn Period. When counting and calculations are needed, the counting is taken out and placed on the table or on the ground.

Although these are inconspicuous little sticks, they have made great contributions in the history of Chinese mathematics.In the later development, these small sticks were directly engraved with numbers for counting and calculation.It was not until the invention of the abacus in the Eastern Han Dynasty that the calculation was gradually replaced by the abacus.

Although Li Yang can't understand how this calculation is calculated, one thing is certain, that is, it is too inconvenient and the calculation is too slow.

Li Yang didn't even dare to think about how long it would take for the other party to calculate the multiplication next.

Because now that the number of people who have not paid in advance has been calculated, the next step is to multiply the number of people who have not paid in advance by the number of people who have paid in advance for each worker, so as to calculate how much food is still to be shipped.

Li You on the side saw that Li Yang was waiting impatiently, so he comforted him with kind words: "Don't worry, my lord, they are people who often calculate, and they will be able to calculate the result soon."

"........."

Li Yang's face was dark, and he was speechless for a while.

Glancing at the person from the firm and starting to fiddle with the calculations again, Li Yang wanted to cry.

I really didn't want to wait another ten minutes, so I asked directly: "How many workers have not paid in advance? How much should each worker pay in advance?"

The person in the firm was also sweating profusely, because he knew that the prime minister next to him was waiting for the result, so he was under great pressure.

At this time, just halfway through the calculation, the calculation had to be interrupted when I heard Li Yang's question, and then replied: "Reporting to the prime minister, there are 610 laborers who have not paid money and grain, and each laborer paid two months in advance. 120 catties."

After hearing this, Li Yang directly used a multiplication formula in his heart, calculated the result in less than 30 seconds, and said, "Seventy-three thousand two hundred catties!"

Everyone was taken aback, looking at Li Yang stupidly, not knowing what he was talking about.

Li Yang said: "According to the truth, we have to transport [-] jin of grain over here."

Everyone: "..."

The person from the firm: "..."

Everyone continued to look at Li Yang in bewilderment, still not knowing what he was talking about.

The people in the firm took a look at Li Yang, continued to fiddle with their calculations with their heads down, and began to calculate the work in hand seriously.

No one seemed to take Li Yang's words seriously.

Li Yang: "..."

I have a saying that my mother sells horses, I don't know if I should say it or not!

Li Yang raised his head 45 degrees and looked up at the sky, his heart was blocked for a while...

In this world, when a person is too smart, isn't it a kind of loneliness?

…………

After about 3 minutes of touching.

Suddenly one person in the crowd was startled and shouted: "My God, my God, the 610 catties of grain that Prime Minister Zhong said was actually the amount of prepaid grain for [-] people!"

When Li Yang heard this, he couldn't help being surprised.

Looking back at the person in the crowd, I saw that it was a man in his 40s. This person was empty-handed, but he had no calculations in his hands.

Li Yang was extremely astonished.

This person... Could it be that he figured out the result so quickly?

This time, Li Yang really had to be shocked. You must know that the person in the commercial firm has not yet calculated the result with calculations, but the man in front of him has no calculations, and it is impossible for him to understand the multiplication formula. Knowing the result, in today's era, this can be called a mathematical genius!

At this moment, everyone couldn't help being suspicious, and said in amazement: "What did you say?"

The man said with a look of horror: "I said that the 610 jin of grain that Prime Minister Zhong said before refers to the amount of money and grain for those [-] people."

"This...isn't it?" Everyone was surprised.

"But Prime Minister Zhong didn't do any calculations just now."

"That's right, Prime Minister Zhong didn't calculate at all, how could it be the amount of money and food for those 610 people. You bastard, what a joke!"

The man looked at Li Yang in surprise, and said, "I'm not joking, what I said is true, because the result I calculated was exactly [-] catties of grain."

After finishing speaking, he immediately bowed his hands to Li Yang and asked, "May I ask Prime Minister Zhong, what you said before is the amount of money and food you calculated for 610 people?"

Li Yang nodded: "That's right!"

Everyone was surprised, but they couldn't believe it.

At this moment, the people in the firm finally made their calculations, but they had a shocked expression on their faces.

Li Yang asked with a smile: "Forget it? What's the result?"

The man from the firm nodded stupidly, and said in great surprise: "Prime Minister Huizhong, it is indeed [-] catties! This...how did you figure it out?"

The people in the commercial firm have to be surprised by this. They calculate the accounts every day, and they are already relatively skilled in calculation.This operation of multiplying hundreds of digits by hundreds of digits requires the use of a calculator to calculate the result.
