Bringing A System To Great Tang

“Old Bi has also learned to write letters, is this to treat me as a pen pal?”

That night, Li Yi received a letter from High Official Bi Gou Private message does not represent the household department.

The letter said two things.

“While crying poor, saying that I dont have money, I want to make up for the military. What I mean by that means I dont want to fight for nothing.”

Li Yi understands, Bi Gou goes around Come and go, turn a kind of entanglement into words.

“Ask me Newspaper if I pay taxes? Of course…I can’t.” Li Yi shook his head when he saw the second thing.

“No?” Li Chengqi helped bring the letter here. It’s winter, and there are oysters to be delivered, and other seafood.

“Can’t hand it in. Newspaper belongs to education and military. It provides more money to the station and helps the people to recognize characters.”

Li Yi refused, giving two reasons.

Newspaper is not owned by his personal official, it is involved in Great Tang’s mouthpiece.

“At the same time, I still need more money to organize manpower to do things. No matter how much Newspapers advertising costs, it will take a long time for the things to be done.”

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

Turning his head, he said to Li Chengqi: “Big brother, before the Yellow River freezes, see if you can freeze a batch of fish and shrimp from Laizhou to Ch_ng’n.”

“How to freeze?” Li Chengqi knows that frozen fish and shrimp are better than dried ones.

“Just…no, the temperature is not low enough, and the water freezes slowly. When the water freezes, Yellow River can hardly leave.

You can wait until it gets colder.

When I was fishing for fish and shrimp in Bohai Bay, I took the ice cubes that had been frozen in winter to fish, and when I caught it, I used ice to settle it.

Back on the land, prepare a mixture of ice and water on the land. Things, put the fish and shrimps in, they freeze hard overnight.

Put them into sacks and transport them by land. At that time, it was cold and the temperature was low. Ice cubes were also ice cubes to Ch_ng’n. “

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

The cost is high, and there are many rich people in Ch_ng’n.

“Try it for brother.” Li Chengqi was moved, mainly because he wanted to eat.

Then he pointed to the letter written by Bi Gou: “Compensation for your military resources…”

“When taxes are collected in the future, there will also be the rent adjustment that Farmstead should call. Deduct from it, when will it be deducted, and when will it be handed in.”

Li Yi is familiar with this kind of thing, both sides have face, and the Imperial Court takes advantage.

Military funds are now given, and there is usury for lending out, which is a lot every day.

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

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

“That’s good, Younger Brother Yi writes a reply.” Li Chengqi also thinks that the Ministry of Households is taking advantage.

Li Yi quickly wrote a reply letter, 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 how to calculate with abacus?” After finishing this matter, Li Yi suddenly asked.

“I know a little bit, I don’t learn well.” Li Chengqi was a little embarrassed. Obviously he knows that point is true.

“I haven’t had anything to do recently. I looked for it. There is a set of formulas that can make it more convenient for people to use abacus instead of learning questions.”

Li Yi laughed and got up. Take out an abacus from the box next to it.

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

“In fact, to calculate the relationship between Jin and Jin, the above two beads, one bead, and different calculation methods are used. It is enough to multiply and divide sixteen.

However, addition and subtraction are compared. Its easy to learn, so there are two pearls on the top, one represents five, and the five pearls on the bottom are also five.

In this way, adding and subtracting to count the two is faster. You dont need to learn more difficult, the accountant can count. Yes.”

Li Yi first introduces the use of beads. The two pearls above are low-allocated to the initial Scholar, and at the same time, they are used for larger counting calculations, and more beads carry more.

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

Eleven in the hexadecimal number is eleven, and twelve is twelve…

“I am going to print this out separately. There will be an issue on Newspaper. , Other needs to be passed to Great Tang places.”

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 is very simple, but his speed is slow.

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

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

“Do you also pass this secret method?” Li Chengqi understands it, it is not difficult. Of course, Li Yi calculates all decimals and integers.

Now Great Tang players have their own methods of playing abacus, which are easily not passed on.

At the same time, a deeper foundation of arithmetic is needed. There are one after another questions. Practice according to the solution in the question.

Now that I have drawn a table on a few sheets of paper, I can understand when I look at it. If I practice, Im basically all-powerful.

“There is another thing that benefits the people, one or two equals 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 0.125 kilograms, he will There is no need to return one.

Three stays at 1875. Three and two stays at this position of the abacus, which is equal to 0.187 kg.

Actually, I put my farmstead in The mathematics taught is good, but its not useful at all. Just take a pen and get it out, and mental arithmetic is fine.”

Li Yi explained the formula and content of the two pairs of pounds on the abacus. He felt In general daily, mental arithmetic is enough.

However, to calculate donkey roll compound interest, mental arithmetic and pen calculations are laborious, unless you know 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 can play chess can simulate it in his mind when he opens the game and doesn’t have many moves.

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

2nd day is 11 thousand yuan multiplied by one point, 12,000 hundred yuan, 3rd day continues to multiply one point by one…

Its too hard to calculate this thing. After a hundred days, my wrist hurts.

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

“Younger Brother Yi, you rewrite, this abacus and method are for my brother, I will practice for my brother at night.”

Li Chengqi saw Li Yi’s movements and felt handsome .

He plans to learn first, and then…

In the morning of 2nd day, Li Chengqi’s eyes were a little swollen, too late to use a hot towel and ran away after breakfast.

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

For the people of Khitan Tribe in Bohai Bay, there is thin ice that freezes in winter.

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

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

“After High Official, 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, breathed a sigh of relief, the method is good, and the tax will be deducted gradually in the future.

After reading the letter, he read Li Chengqi, Prince of Song, why dont you leave? Need to reply?

“After High Official, can you know abacus?”‘Wow, wow! ‘Li Chengqi shook the abacus, placed it on the table in front of Bi Gou, and returned.
