Bringing System to Great Tang

Chapter 529: 2 new ideas

"Old Bi has also learned to write letters. Is this to treat me as a pen pal?"

That night, Li Yi received a private message from Shangshu Bigou of the Household Department, which does not represent the Ministry of Household.

The letter said two things.

"While crying poorly, saying that I don't have money, and at the same time I want to make up for the military funds, the meaning in the words is that I don't want to fight for nothing."

Li Yi understood, and Bi Go went around, turning a kind of entanglement into words.

"Ask me if I pay taxes in newspapers? Of course...I can't pay them." Li Yi shook his head when he saw the second incident.

"No?" Li Chengqi helped bring the letter. It was winter, and there were oysters to be delivered, as well as other seafood.

"No, newspapers belong to education and military affairs. They provide more money to the inn, and at the same time help the people to recognize characters."

Li Yi refused, giving two reasons.

The newspaper was not owned by his personal official, and it involved Datang's mouthpiece.

"At the same time, I still need more money to organize manpower to do things. No matter how much newspaper advertising costs, it will take a long time to invest in what I want to do."

Li Yi has his own calculations, the money earned by the newspapers, and he will use it for other things in the future.

Turning his head, he said to Li Chengqi: "Brother, before the Yellow River freezes, see if you can freeze a batch of fish and shrimp from Laizhou to Chang'an."

"How to freeze?" Li Chengqi knew that frozen fish and shrimp were better than dried ones.

"Just...no, the temperature is not low enough, the water freezes slowly, and when the water freezes, the Yellow River can hardly go.

When it gets colder and colder, you can fish and shrimp in the Bohai Bay. Take the ice cubes that have been frozen in winter to fish.

Back on the land, prepare a mixture of ice and water on the land, put the fish and shrimp in it, and it freezes overnight.

Put it in sack and transport it by land. It was cold and the temperature was low at that time. The ice cubes were also ice cubes to Chang'an. "

Li Yi vetoed the method of grabbing water transportation on the Yellow River and changed it to land transportation.

The cost is high, and there are many wealthy people in Chang'an.

"Try it for brother." Li Chengqi was tempted, mainly because he wanted to eat.

Then he pointed to the letter written by Bi Gou: "Compensation for your military resources..."

"When tax is collected in the future, there will also be the rent adjustment that Zhuangzi should call, deduct from it, when the deduction is over, and when will it be paid."

Li Yi was familiar with this kind of thing, both sides had face, and the court took advantage.

The military funds are now given, and there are stamps of money when the loans go out, and there is a lot of money every day.

Li Yi didn't plan to ask for that money. He wanted to be a prisoner. A captive of 50,000 yuan would be a profit in itself.

As for the giant panda, it is currently a personal hobby.

"That's fine, Brother Yi writes a reply." Li Chengqi also thought that the Ministry of Household was taking advantage.

Li Yi quickly wrote a reply, telling Bi Gou that he did not pay advertising tax, and explained how to operate the military assets, and handed it to Li Chengqi.

"Big brother, do you know abacus?" After finishing this matter, Li Yi suddenly asked.

"Know a little, don't learn well." Li Chengqi was a little embarrassed, obviously he knew that was true.

"I haven't had anything to do recently. I searched for it. There is a set of formulas that can make it more convenient for people to use abacus instead of studying problems."

Li Yi smiled, got up and took out an abacus from the box next to him.

Two beads on the top and five beads on the bottom.

"Actually, to calculate the relationship between Jin and Jin, you don't necessarily need the two beads above, one bead, and using different calculation methods, it is enough to multiply and divide sixteen.

But addition and subtraction is easier to learn, so there are two beads on the top, one represents five, and the five beads on the bottom are also five.

In this way, adding and subtracting to calculate the catty is faster, you don't need to learn more difficult, the accountant can do the calculation. "

Li Yi first introduced the use of the beads. The above two beads are for beginners at a low level. At the same time, they are used for larger counting calculations, so more beads carry more.

After speaking, he took out a few pieces of paper with tables drawn on them, writing decimal addition, subtraction, multiplication, division, and hexadecimal.

Eleven in hexadecimal is eleven, and twelve is twelve...

"I'm going to print this out and print it separately. There will be one issue in the newspaper, and other needs will be passed to all parts of Datang."

Li Yi put the form in front of Li Chengqi.

He also personally operated the addition, subtraction, multiplication and division of the two bases, which was very simple, but his speed was slow.

He is not proficient. He has never learned abacus and mental arithmetic, and he has learned abacus in elementary school, but he didn't use it later, he forgot.

Suddenly I wanted to come, check the information, and think about it myself before I could show it to others.

"Do you also pass this secret method?" Li Chengqi understood it. It's really not difficult. Of course, Li Yi calculates all decimals and integers.

Now Datang's abacus players have their own methods, which are easily not passed on to others.

At the same time, a deeper foundation of arithmetic is needed, and there are a series of questions, which are practiced in accordance with the solutions in the questions.

Now I have drawn a table on a few pieces of paper, and I can understand it by looking at it, and then I will practice, basically it is all-powerful.

"There is another thing that benefits the people. One or two is equal to how many catties. I write now, this is one retreat of six and two five, and one or two equals zero, six and two five catties.

This refund is calculated by only one refund, otherwise it will be 0.625 kilograms.

Two leaves one two five, two two equals one hundred and twenty-five catties, so he doesn't need to retreat one.

Three and one hundred and seventy-five are left, and three and two are left in the abacus position, which is equal to one hundred and eighty-five catties.

In fact, I have learned the mathematics taught in Zhuangzi well, but I can't use it at all. I can figure it out with a pen, and my mental arithmetic is fine. "

Li Yi explained the formula and content of the two pairs of catties on the abacus. He felt that his mental arithmetic was enough for ordinary daily life.

However, calculating the compound interest of the donkey's rolling profit, the mental arithmetic and the pen calculation are laborious, unless you know the abacus mental arithmetic.

Abacus mental arithmetic itself simulates an abacus in your mind, just like playing chess without looking at the board and playing blind chess.

Anyone who knows how to play chess can simulate it in their minds when they open the market and don't have too many moves.

The simplest explanation for compound interest is stocks, the daily limit is 10%, 10,000 yuan, multiplied by 1.1, 111,000 yuan.

The next day is 11 thousand yuan multiplied by 1.1, 12,100 yuan, and the third day continues to multiply by 1.1...

It’s too much effort to count this thing with pen. After one hundred days, the wrist hurts.

Li Yi thought, shaking the abacus back and forth, swiping the position of the bead with his hand, returning to its place.

"Brother Yi, you rewrite this abacus and method for your brother, and practice it at night for your brother."

Seeing Li Yi's movements, Li Chengqi felt handsome.

He intends to learn first, and then...

The next morning, Li Chengji's eyes were a little swollen~www.wuxiaspot.com~ too late to use a hot towel, and ran away after eating breakfast in a hurry.

He first arranged for the transportation of the Yellow River before it was frozen in winter, and then sent someone to Laizhou to wait for it to be cold and try to transport them back with frozen fish and shrimp.

To the Khitan people in Bohai Bay, the winter ice over there is thin ice.

After processing, he went to the imperial city to find Bi Gou with a letter.

When Bi Gou saw Li Chengqi, his eyes rested on the abacus under his arm.

"Bi Shangshu, the matter is done, I will reply to you." Li Chengqi first handed the letter to Bi Gou.

Bi Gou unfolded and took a look. He breathed a sigh of relief. The method was good, and the tax would be deducted slowly later.

After reading the letter, he looked at Li Chengqi, why don't you leave, Song Wang? Need to reply?

"Bi Shangshu, can you know abacus?" "Wow, wow! Li Chengqi shook his abacus, placed it on the table in front of Bi Gu, and returned to his place.
