Don't look at the people in the household department It took half a year to liquidate it, and Li Su is really confident that it will be liquidated within half a month with these 'primary school students'.

After all, in terms of numbers, they are definitely more than the people of the household department.

It is impossible for the household department to do nothing, and all the personnel come to settle the accounts of previous years.

In terms of efficiency, the two sides are even less comparable.

Wherever they are in business, whether it is a Chinese commercial bank or the first floor in the world or the first courtyard in the world, they have their own account rooms.

In the past, Li Su had also watched them keep accounts and settle accounts.

The numbers are first written down in Chinese characters, and a simple addition is calculated, as long as the number is large, it is necessary to break your fingers and count it for half a day.

It is also extremely inconvenient to write it down again.

Seeing that they were so troublesome in settling accounts, Li Su directly taught them how to keep accounts in Arabic numerals.

And they are required to use the method of cross-accounting, so that the accounts are clear at a glance, and it is simply impossible to keep false accounts.

And since they learned Arabic numerals and column vertical calculations, their time to calculate accounts is simply more than ten times faster.

And these bookkeepers also shocked Li Su as a celestial.

There are really a lot of account books for three years in the household department, as many as one room.

But in each of these ledgers, there are not many numbers.

Because they are all written with a brush and Chinese characters, no matter how small your font is, how small can it be?

A ledger can usually be counted completely if a table is not used up.

However, the number of ledgers is still a bit much.

Li Su felt that if all these account books were counted, it would take about three or four days.

However, if you simply add numbers to the ledger, it will be very fast.

And Li Su also gave them a method of verification, after calculating the number, they can also add the remainder and the total amount of expenditure to check.

If it doesn't match, then it proves that the numbers were added incorrectly.

In this way, they can be sure that the numbers they calculate are correct.

……

At this time, Li Shimin called Li Su in.

After Li Su entered, Li Shimin couldn't help but say to him: "Su'er, you shouldn't have agreed to their bet." ”

In Li Shimin's opinion, even if he doesn't agree, this is my son, as long as I don't want to deal with it, do you still want to do anything to him?

Hearing Li Shimin's words, Li Su smiled and said, "Father, how can the sons and daughters not know that they are deliberately messing around?" However, Erchen believes that these number symbols are really very useful and worth promoting throughout Datang. ”

The advent of Arabic numerals and mixed symbols has given a huge boost to mathematics.

Li Su is mainly to promote numbers and operation symbols, otherwise, how could Li Su be so bored and agree to bet with them?

was said by Li Su, Li Shimin also remembered that before this, Mr. Wang Xiaotong of arithmetic had also had a twist and turn.

At that time, he talked about the promotion of numbers and arithmetic symbols.

However, after asking Li Tai at that time, he ignored the matter and finally gave up.

Unexpectedly, Su'er actually attaches so much importance to this set of numbers and operation symbols?

Li Shimin couldn't help but ask: "Su'er, is this number and operation symbol really so magical?" ”

Li Su smiled slightly and said: "Father, you can rest assured, the son of the minister judged that it would not take half a month to calculate the number at all." ”

Li Shimin couldn't help but ask: "Su'er, do you really need your father to send you additional people?" ”

Suddenly!

It turns out that my father can't help but want to cheat, and is going to secretly send him more people!

Li Su smiled and said, "I really don't need to!" ”

The people that my father can send out will not be able to use Arabic numerals, nor will they mix the four operations, and it will not be useful to send them in the past.

Besides, once it is known, it is a troublesome matter.

However, Li Shimin actually has such a calf protection side, which makes Li Su very moved.

Li Shimin couldn't help asking: "Su'er, although this flood did not cause major casualties. However, many people have lost their homes and suffered heavy losses. And now, the border is unstable, the Turks are ready to move, and it is difficult to come up with this amount of money in the treasury. What do you think we should do now? ”

After finishing speaking, Li Shimin looked at Li Su with an expectant face.

Suddenly!

The sensationalism just now, just to wait for me here!

Li Zhuocai didn't believe that the treasury was so poor that it couldn't even take out this money!

Seeing Li Su's expression, Li Shimin couldn't help but say: "Su'er, do you think that only the people near Chang'an City have suffered?" ”

"The people near Chang'an City, because of you, are the least affected. But downstream, hundreds of people's houses have been washed away, and now they don't even have a stutter. There is an urgent need to deliver large quantities of relief food and medicinal herbs. ”

"As for the people around Chang'an City, because they are the least affected, the imperial court really doesn't have the financial resources to rescue them now!"

Listening to Li Shimin's words, Li Su couldn't help but nod thoughtfully.

Yes, with such a heavy rain and so much water in the river, it makes no sense that only the people near Chang'an City suffered.

But what does my father mean by telling me so much now?

He didn't want me to pay out of my own pocket for the victims, did he?

Sure enough, I heard Li Shimin say: "Son, my father knows that you have made a lot of money in business. Of course, you earned all this money based on your ability, and your father will not let you take it out for nothing. Now, you take some of the money for disaster relief first, and your father will give you an IOU. When there is money in the treasury, I will definitely return it to you with interest. ”

Well?

Are you looking for me to borrow money?

The question is, I'm going to actually lend it out, when will you have the money to pay me back?

disaster relief, and even asked him to donate some of his money, Li Su is really willing.

But there are too many victims, nearly 20,000 victims, if you want to properly resettle them, this is the rhythm of his family!

This kind of thing, Li Su will never do.

But those victims of the disaster cannot but be relieved.

After all, the houses of the villagers in the eleven villages downstream were all burned down by Li Su.

Although the end result was to save their lives, in any case, it was Li Su who made them lose their homes.

If you don't settle for them, Li Su's conscience will be uneasy.

But such a great good deed should not be done by him alone.

No, there are so many rich people in Chang'an City, how can he let himself be beautiful?

After thinking for a while, Li Su suddenly thought of a way, and couldn't help but say to Li Shimin excitedly: "Father, there is a way!" ”
