Liu Zhi immediately hung a huge piece of rice paper on the screen, and then took a pen, ink, paper, and inkstone, and placed the four treasures of the study on the treasure case, and the screen was placed in the most conspicuous position on the throne.

The court is a more serious place, but now there are problems to be discussed, so Ran Min can't care about these etiquette.

"Ahem!"

After coughing twice, Ran Min immediately walked to the front of the screen like a teacher, holding a pen and an inkstone, and said, "Now I will teach you Arabic numerals." It's 0, it's 1, it's 2. ”

Ran Min wrote down the ten number symbols 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9 on a piece of rice paper.

"These ten numbers are a kind of counting symbol. The high position is on the left, the low position is on the right, and write from left to right! Cui Hao, is it the first big or the ninth? ”

"Naturally, it's nine!"

"Not bad." A teachable look appeared on Ran Min's face, and he said, "Zero is the most important value, and nine is the largest value." Now that I have come to teach you addition, subtraction, multiplication and division, you will be able to understand how I came to the conclusion that if I deposited 10,000 yuan in the money bank three months ago, I would get 65 yuan in interest after three months. ”

Ran Min stretched out a finger and said, "How many is this?" ”

"A finger!"

"I didn't ask you this, you just counted."

"One!"

"Yes. So how many is this? Ran Min raised two fingers.

"Two!"

"Correct." Ran Min bowed slightly: "So one finger plus one finger is two." ”

Ran Min wrote an addition formula and a subtraction formula on rice paper, and began to teach the ministers slowly.

In addition to this Arabic numeral, there are addition, subtraction, multiplication, division, and percentages, and Ran Min also taught the multiplication formulas to the ministers and ordered them to memorize them well.

"Now you understand, right?"

Cui Hao's eyes lit up and said, "Your Majesty, the minister understands!" ”

"Then you do the math. Now change the conditions, if you deposit 10,000 yuan in the bank six months ago, how much interest can you get if you withdraw it after six months? I will give you one more time, and the formula for calculating the interest on the deposit is: the interest is equal to the principal multiplied by the interest rate and multiplied by the time. However, I still want to remind you that the annual interest rate of the five-month lump sum deposit and withdrawal of the money bank is 2.6%, because the interest rate of the money bank is generally expressed in the annual interest rate, so when calculating the interest, you must pay attention to converting the interest rate to the interest rate that matches the time, or converting the time to adulthood before calculating! ”

When the ministers heard this, they all began to rack their brains to ponder, but they were at a loss for a while, and they really couldn't figure it out.

Just changed the conditions, so that these clever and witty ministers were stunned for a while, and Ran Min's vanity was very satisfied.

At this time, Cui Hao said again: "Your Majesty, can you give the pen and paper to the minister?" ”

"Yes."

Ran Min then asked Liu Zhi to hand the pen and paper to Cui Hao and asked him to calculate slowly.

It's not that their minds are not bright and witty, but they have just come into contact with these new things, and they still need time to get used to them!

After a while, when Ran Min had already begun to yawn, the first person to come up with the answer was not Cui Hao, but Qin Mu, who had been silent.

"Your Majesty, the minister has come up with it!"

"Oh? How much? ”

"The interest is one hundred and forty dollars!"

Ran Min's eyes widened, and he suddenly changed color and said, "How did you calculate it?" ”

This mental arithmetic is so powerful? Qin Mu's intelligence is too perverted, right?

Qin Mu smiled and said, "Your Majesty, according to the formula you gave at the right time. Interest is equal to the principal multiplied by the interest rate multiplied by the time. The principal is 10,000 yuan, and the interest rate is 2.8 percent, so the minister takes 10,000 and multiplies it by 2.8 percent, and the value is 280 yuan. The rest of the time is just calculated, twelve months in a year, and the condition given by His Majesty is six months, then divide twelve by six to get the value of two. Then, isn't the two hundred and eighty divided by two to one hundred and forty dollars? ”

Hearing this, Ran Min was stunned, and the ministers were even more in an uproar, praising Qin Mu's wit and shame.

"Master Cui, have you figured it out?"

"The old man, the old man, of course calculated it, and the value is one hundred and forty." Cui Hao actually didn't figure it out, his old face was red, of course he couldn't pull his face down to recognize four.

At this time, Wang Meng came out and said: "Your Majesty, the minister thinks that this Arabic numerals, addition, subtraction, multiplication and division, percentages, and multiplication formulas are very important to the people's livelihood, and should be taught to the people, taught in the school, so that everyone knows His Majesty's sage!" ”

"Your Majesty Shengming!" Qunchen Mountain shouted.

Ran Min smiled from ear to ear: "Hahahaha!" These mathematical things are naturally to be taught to Rao. The officials in charge of the warehouse, as well as the local bookkeepers and county officials, often worry about some account books, and with these Arabic numerals, addition, subtraction, multiplication and division, they should be able to make it much easier, and the account books can be easier to understand. ”

"This is really a great achievement, Your Majesty!"

was touted by the ministers again, Ran Min's face was a little feverish, so he waved his hand and said, "Back to the topic." What do you think of my method of setting up a bank? ”

"Naturally, it's wonderful! Just ......"

Wang Meng couldn't help frowning, and said: "Your Majesty, this interest rate is too high, so let it benefit the people, I'm afraid there will be a mistake in the court's finances." ”

"Haha, Jingluo, you're too worried." Ran Min shook his head and said, "This money bank is state-owned, and it won't do any loss-making business!" We can give some interest to the people who save money in the bank, and naturally some people give us the interest, in the end, this money bank is still a big money-making tool for the imperial court! ”

When the ministers heard this, they were all very confused.

"Your Majesty, please!"

"The Dawei Bao banknotes issued by Qian Zhuang are circulating in the market, which is cash and should be accepted by the people. You can exchange treasure banknotes or copper coins and silver at will, and the face value of treasure banknotes can be exchanged for treasure notes of the same value with multiple pieces. In order to make money, the bank can also issue some businesses, such as depositing foreign exchange, discounting, exchanging and other credit services. Money banks can absorb more deposits from merchants and collect bills on behalf of them, and the loans they operate are credit loans, mortgage loans, short-term interest loans, etc. The loan is mainly for firms. ”

Ran Min's words made the ministers hear in a fog, and they didn't understand many words, but after Ran Min's explanation, they understood the meaning.

The money bank can lend money to the merchant, that is, to lend the money to the merchant, but when the money is repaid, it must repay the higher interest, so that the money bank is actually making money.

But the clever Wei Yan smelled a different flavor from it, and hurriedly said: "Your Majesty, are you encouraging the people to do business?" ”

"Why did you say that?"

"Your Majesty, everyone in the world is chasing fame and fortune, and many people want to get rich, but they have no capital and no opportunities, so they are just ready to move and do not go into business. Now that the imperial court has created such a money bank, lending money to those people who want to do business but have no capital, isn't it encouraging the people to do business? ”

"This ......"

Before Ran Min could think about how to refute Wei Yan's words, the ministers disturbed the ground and made up their minds to engage in the matter of Huangqian Village.

"Your Majesty, what Lord Wei said is extremely true! All the Chinese dynasties and dynasties in China have built the country on agriculture, and without farming, the country will have no foundation. If all the people run away to do business, who will plough the land for the state? ”

"Yes! Please think twice about your majesty! The country is unshakable. Peasants are the foundation of the country's life, and if everyone is in business, they will be filled with the smell of copper, and they will not know loyalty, righteousness and shame. As the saying goes, no business, no treachery, no business! These businessmen can certainly generate income for the country's finances, but it is really difficult to fill their stomachs! ”

Seeing that the ministers all jumped out to oppose it, Ran Min's heart was very annoyed, but he still said lightly: "The implementation of the Great Wei treasure banknote, as well as the implementation of the money bank, is an imperative thing. In my opinion, it is not advisable to emphasize agriculture and suppress business, and there should be no difference between agriculture and commerce, and you slander these merchants who are full of copper smell all over your body, don't you know that the silk you wear, the tea you drink, and the bird's nest you eat are all operated by them from all over the country? ”

Seeing that Ran Min seemed to be insisting on promoting the Great Wei Bao banknote and insisting on promoting the money village, the ministers all sighed secretly in their hearts, it was difficult to dissuade, so they could only "save the country by curve".

Wei Hu said: "Your Majesty, in fact, the minister thinks that there is no need to implement the Great Wei treasure banknote. Dawei Bao banknotes are made of paper, easy to be damaged, and easy to be imitated by those who have intentions, when the time comes to disrupt the order of the market, I am afraid that it will be a huge disaster! ”

"I've thought about that. The production of Dawei treasure banknotes must be strictly controlled, and it must be different from ordinary paper, and there is a certain anti-counterfeiting mark. For those criminals who dare to imitate the Great Wei Bao banknotes and undermine the country's reputation, they will be severely punished! ”
