The Great Ming Demon Pill: Your Majesty, please address me as the Crown Prince!

Zhang Mao looked aggrieved.

"Your Highness, how would we know this was mathematics?"

"We haven't learned anything that advanced yet."

"Yes," Li Heng nodded, "but I believe that this will be a piece of cake for us from now on."

Zhu Zhanqi also deeply agreed.

"Second brother, I think they're right."

"Calling us stupid is going too far."

"Believe it or not, in a fit of anger, I'll learn all this math!"

Zhu Zhanjun sneered.

"A person can accomplish many things when they are angry."

"He's just bad at math."

Zhu Zhanqi: "..."

It seems that it really is.

Zheng Yu leaned closer.

"Your Highness, I noticed you seemed rather nonchalant just now."

"Could it be that he has already mastered this mathematics?"

Zhu Zhanjun pursed his lips.

"Mere mathematics is a trivial skill; I am a sage of this field, how could I not refine it in an instant?"

Li Heng was completely bewildered.

"May I ask, class monitor, what kind of saint is this undergraduate saint?"

Zhu Zhanjun rolled his eyes.

"You wouldn't understand even if I told you."

A group of people were chattering away.

Huang Guangyun and his assistant pretended not to hear.

Yang Rong, standing next to him, looked somewhat embarrassed.

He coughed lightly.

"Your Highness, mathematics may seem dry and boring, but it is the foundation of practical application. Astronomy, calendar systems, water conservancy projects, taxation, military supply management, and even daily crafts all rely on it."

"Your Highness, please do not underestimate the vast knowledge of the world and the many talented individuals in this prison just because you are young and fond of fun."

Zhu Zhanjun glanced at him sideways.

"I didn't underestimate him."

"It's just that this kind of arithmetic isn't very sophisticated."

[Ding! You have obtained a silver treasure chest!]

Yang Rong managed to keep his composure after hearing the first sentence, but he couldn't hold back anymore when he heard the second one.

You little brat, you look down on the mathematics of the Imperial Academy?

Huang Guangyun, who was standing next to him, said with a smile.

"Your Highness is indeed an extraordinary person, with remarkable spirit."

The several mathematics PhDs behind him were somewhat indignant.

Although the Prince of Jiyang was renowned, he was a specialist in his own field.

In the field of mathematics, they were not afraid of the Prince of Jiyang.

A mathematics PhD, around thirty years old, smiled.

"Since His Highness the Prince of Jiyang thinks that the mathematics of our Imperial Academy is not very advanced..."

"Then may I ask His Highness Prince Jiyang for some guidance?"

Zhu Zhanjun pursed his lips.

"Alright, since you've asked so sincerely, I'll be merciful and give you some pointers."

If you can't answer within ten breaths, I'll admit defeat.

[Ding! You have obtained a silver treasure chest!]

[Ding! You have obtained a silver treasure chest!]

[Ding! You have obtained a silver treasure chest!]

Everyone: "..."

This guy is too arrogant!

The mathematics PhD's eyelids twitched, and he immediately said.

"In that case, Your Highness, please calculate: what is twenty-three multiplied by forty-seven?"

Zhu Zhanjun didn't even lift his eyelids, and casually answered, "One thousand and eighty-one."

The doctor was slightly startled.

Although the question was not extremely difficult, it would still take an ordinary person a while to calculate even by hand, but this child was able to answer it off the top of his head, and the answer was correct.

He composed himself and posed another question: "Then... what about 156 times 289?"

The corridor outside the hall immediately fell silent.

Zhu Yi, Zhang Mao, and the others looked at each other in dismay. The number sounded huge, and they hadn't even memorized all the questions.

Yang Rong, Huang Guangyun, and others also looked at Zhu Zhanjun. Multiplying three numbers is by no means an easy task, even if done mentally.

Zhu Zhanjun merely tilted his head and said lightly, "Forty-five thousand and eighty-four."

The mathematics PhD's expression finally changed.

He quickly calculated and verified it in his mind. After a while, his eyes were filled with disbelief. It was exactly the same as before!

How is that possible?

Even an experienced official specializing in mathematics needs time to mentally calculate three-digit multiplication. How old is the Prince of Jiyang?

The students who were listening to the lesson inside the hall were also attracted by the commotion in the corridor and turned their heads to look.

Dr. Li Shimian also stopped his explanation and frowned as he looked out the door.

Zhu Zhanjun crossed his arms and said with a smile.

"Can you do something a little more difficult?"

The mathematics scholar took a deep breath, steadied himself, and said in a deep voice, "In that case, Your Highness, please listen to the question: What is the result of multiplying three thousand four hundred and fifty-six by eight thousand nine hundred and one?"

Upon hearing this question, not only were Zhu Yi, Zhang Mao, and others dumbfounded, but Yang Rong, Huang Guangyun, and the other students in the hall were also secretly astonished.

Multiplying four-digit numbers requires considerable effort, let alone mental calculation, and is also prone to errors, even when done with pen and paper.

Zhu Zhanjun, however, remained nonchalant and spoke almost immediately after the doctor finished speaking: "Three thousand four million five hundred and sixty-seven thousand eight hundred and ninety-nine."

The doctor was sweating profusely and quickly went to the side to pick up a pen and ink to start calculating.

Li Shimian and the other students inside the room were also dumbfounded.

After a while.

The doctor suddenly raised his head with a strange expression.

"Your Highness Prince Jiyang, your calculations seem incorrect."

Zhu Zhanjun gave a soft snort.

"Just tell me, is it fast or not?"

Everyone: "..."

Zhu Zhanjun shook his head.

"That's enough, that's enough."

"I'm not kidding you guys anymore."

"The result is 30,761,856."

The doctor's expression changed instantly, staring incredulously at the answer on his paper.

It was exactly the same as his answer.

Even though Zhu Zhanjun spent so much time mentally calculating, it was still remarkable.

The doctor immediately took a deep breath and cupped his hands in greeting.

"His Highness Prince Jiyang is truly a genius of mental arithmetic."

Zhu Zhanjun pursed his lips.

"What's so great about being a genius?"

"I've met many geniuses, and they all have to call me Grandpa, Your Majesty!"

Everyone: "..."

That's absolutely right.

"Your Highness, Prince Jiyang." Li Shimian, who appeared out of nowhere, had a piercing gaze. "I just heard about Your Highness's mental arithmetic abilities, which are truly astonishing."

"However, the intricacies of mathematics go beyond just rapid multiplication and division."

"I have a question, which, though not profound, requires step-by-step deduction. I wonder if Your Highness would be willing to give it a try?"

Zhu Zhanjun blinked and said with a grin, "Dr. Li, please ask away. I am the master of all kinds of mathematical arguments."

Li Shimian stroked his beard and slowly read the question:

Two people, A and B, each have an unknown amount of money. If A receives half of B's ​​money, they will have a total of forty-eight. If B receives more than half of A's money, they will also have a total of forty-eight. How much money did A and B originally have?

As soon as the question was posed, the corridor fell silent.

Zhu Yi, Zhang Mao, and the others were completely confused and only felt hungry.

The civil officials, including Yang Rong and Huang Guangyun, nodded slightly. This question was indeed a classic problem from the "Nine Chapters on the Mathematical Art," requiring the setting of the Heavenly Element and the Earthly Element. It was already a problem at a relatively high level in mathematics, and even ordinary students would need paper, pen, and counting rods to work on it for a long time.

Li Shimian looked at Zhu Zhanjun and added, "Does Your Highness need paper, pen, and counting rods? This problem is complex and time-consuming to solve."

Zhu Zhanjun waved his hand, looking relaxed: "Why bother with paper and pen? I can do mental calculations for this kind of problem."

Everyone looked at each other.

Li Shimian was also taken aback, then his expression turned serious.

"Your Highness is indeed talented, but this kind of problem cannot be solved mentally without the aid of abacus calculation. Your Highness should not be too arrogant."

Zhu Zhanjun ignored him, thought for a moment, and then spoke.

"A has thirty-two coins, and B has thirty-two coins. Dr. Li, is that correct?"

Li Shimian's eyes suddenly widened.

"This...this..."

He knew the answer because he had taught students this kind of problem before. If he were to deduce it himself, he would have to spend a long time figuring it out with counting rods.

How did His Highness Prince Jiyang calculate that?

Although Yang Rong, Huang Guangyun, and the others did not know the answer, they were stunned to see that Li Shimian also knew the answer was correct.

Li Shimian immediately took a breath and said with heartfelt admiration.

"Your Highness is a diviner."

"However, such problems have always been solved using binary methods and abacus. I wonder how Your Highness calculated them?"

The other mathematics PhDs also stared at Zhu Zhanjun in shock.

Zhu Zhanjun chuckled, spread his hands, and gestured for them to bring paper and pens.

Once he had paper and pen, he casually wrote down a system of equations and handed it to Li Shimian.

Li Shimian and the group of doctoral students were completely baffled.

"Your Highness, this..."

Zhu Zhanjun described it casually.

"I simplified numbers and created these mathematical symbols: forty-eight is 48, ninety-six is ​​96, two is 2, three is 3..."

"And change the Heavenly Origin and Earthly Origin symbols to X and Y."

"+" means addition, "−" means subtraction, and "=" means equal; fractions are written as two numbers above and below each other with a horizontal line in between, meaning fraction. By listing the equations in this way, the meaning of the problem is clear at a glance, and the derivation can be done step by step without the need for counting rods, and it is also less likely to make mistakes."

"Therefore, by simply listing a simple equation, the answer can be calculated."

Upon hearing this, Li Shimian stared intently at the strange symbols and formulas on the screen, his whole body trembling.

Although it was the first time he had seen these symbols, as a scholar of the Imperial Academy, Zhu Zhanjun gave him a brief explanation and he immediately understood their meaning.

These mathematical symbols are truly groundbreaking inventions!

The other mathematics PhDs were also shocked and felt their scalps tingle.

Suddenly, a person bowed deeply.

"Your Highness, I wish to become your disciple and beg you to teach me this art!"

The other PhDs also realized what was happening and bowed deeply.

"Please teach me this technique, Your Highness."

Yang Rong and Huang Guangyun looked at each other in bewilderment.

Is this kid here to observe the ceremony, or to cause trouble?

Even a PhD in mathematics would admit defeat?

Zhu Yi, Zhu Zhanxi, Zhang Mao, Li Heng, Liu Zhong, Zheng Yu, and others were immediately filled with excitement, their eyes glowing red.

Although it was His Highness alone who impressed all the Imperial Academy scholars.

But His Highness is a man, and they are men too.

If His Highness is convinced, doesn't that mean they are convinced as well?

win!

Zhu Yi shook his head and said.

"Genius is merely the threshold to meeting Your Highness."
