Mad Concubine Married: Black-bellied Lord, wait and see

Chapter 302 The second child schemed against Xuanxuan and failed

Jinxuan looked at Lu Zhikun playfully: "Master Lu is willing to return the silver taels. Thank you so much. Master Lu, the Princess has estimated in her heart that the food for a season is about 24 catties."

boom!
Lu Zhikun was stunned by Jinxuan's words. 24 catties of grain converted into silver is not a lot. This is a huge number. Is Fang Jinxuan trying to make him a pauper?

Nangong Ruize and others secretly praised Jinxuan for being smart. At this time, Lu Zhikun should have nowhere to hide. Who told him that he would return the money in front of the emperor.

The emperor smiled and said: "Xuanxuan, you are good at arithmetic, tell me, how do you calculate?"

Jinxuan smiled: "Reporting to Your Majesty, the land you gave my grandfather is all fertile land. Calculated according to the land output of our Shuixi country, one mu of land can produce about 24 catties of grain, while my grandfather's farmland has Eight hundred mu, three hundred times eight hundred, is [-]."

The emperor was curious: they always use abacus to calculate accounts, but Jin Xuan can calculate it in one breath, which really surprised him.

"Xuanxuan, have you ever used an abacus before?"

Jinxuan smiled and shook her head: "I never use an abacus, I do it in my head."

mental arithmetic?

The officials present were also very curious, is the mental calculation accurate?

"Xuanxuan, who gave you the mental arithmetic?" Shang Heng looked at Jinxuan in doubt, "Can you tell us?"

Jinxuan thought to herself: People in Shuixi Kingdom don't know the tables of multiplication formulas and division formulas.

Nangong Ruize smiled slightly at Jinxuan: "Xuanxuan, not only Mrs. Shang is curious, but I am also curious."

It was originally about Lu Zhikun's money and food owed to her, but now it has become a mathematics seminar. Hey, she can't tell that she learned it from the 21st century.

After a long time, Jinxuan said flickeringly: "Your Majesty, Uncle, Brother Rui, in fact, this is what I usually figured out, and I found that the calculation is very accurate."

In order to squeeze Jinxuan, the second prince raised his voice on purpose: "Father, the princess is so smart that she can do mental calculations, why don't we ask shopkeeper Zhao to bring the abacus and let them compare it to see if the abacus is fast. It's still the princess who counts quickly."

Although the emperor knew that the second prince had no good intentions, he wanted to know what mental arithmetic was, so he agreed to let Zhao Kui bring the abacus to compete with Jinxuan.

……

Xiao Mian, she is good at arithmetic even elementary school students, can she still be stumped?When the time comes, the second child, don't cry.

Seeing that Jinxuan is so confident, Nangong Ruize doesn't need to worry, because he knows that Jinxuan will not do anything he is not sure about.

After a while, Zhao Kui brought the abacus.

"Your Majesty, the villain is so clumsy, he's making a fool of himself."

The emperor took a look at Zhao Kui: "Since everyone is interested in Xuanxuan's arithmetic, then I will set a test for Xuanxuan."

The emperor paused for a moment, and then said: "A farmer who sells oranges has 73 catties of oranges. If he sells them for three Wen per catty, how much silver taels should he get?"

"210 nine words." Just as the emperor finished speaking, Jinxuan gave the answer. Isn't this the multiplication in the first grade of elementary school?

Zhao Kui looked at Jinxuan in surprise: "Princess, you are so powerful, you can give the answer without abacus."

"Xuanxuan, then uncle will also test you. If a catty of rice sells for twelve cents, and we want to buy 110 catties, how much silver do we have to pay?" Shang Heng wants to talk about big numbers, Kao Jinxuan .

Jinxuan counted for a few seconds: "Uncle, we need to pay 380 Wen, which is 13 taels and 380 Wen."

When Shang Heng was posing the question, Zhao Kui was also calculating how much money he would have to pay, and the answer was exactly the same as Jin Xuan's.

Seeing such a result, the second prince turned green with anger. He thought that Jinxuan was bragging to please the emperor on purpose, but Jinxuan had the real stuff.

Nangong Ruize glanced at the second prince indifferently: "Second brother, do you think Xuanxuan is right?"
