Wei Zheng and others are different from ordinary ministers.
For them, the meaning of Tiance Mansion is special, just come directly and honestly, there is no need to deliberately lose.
but……
Before Wei Zheng and others started to calculate, Changle suddenly took a piece of white paper from Li Sheng's desk, then picked up a charcoal pen to write and draw.
Wei Zheng and others were startled, what are they playing at...Does the result need to be written down on paper? There seems to be no such thing...
Although he was suspicious, he still started to calculate.
And at this moment, Xiao Changle suddenly raised his little head.
"Master, multiply twenty-seven by thirty-two, the result is eight hundred and sixty-four!"
A childish voice sounded.
Li Er was stunned for a moment.
Wei Zheng was stunned for a moment.
Du Ruhui was stunned for a moment.
Fang Xuanling was stunned for a moment.
The four of them were all stunned, and then their minds subconsciously got a little stuck.
It's not that this number feels wrong, but...
Why did you say it so quickly?
Of course, the main reason is because this number is very specific.
A strong sense of concreteness!
And such a specific number...
How did His Highness Changle say it all at once?
However, they were still confused, so they quickly started calculating in their heads.
And a moment later...
Fang Xuanling's face turned pale first——
"this……"
For a moment, Fang Xuanling couldn't even speak clearly, and her face turned... petrified!
At this time, Li Er was doing mental calculations carelessly, thinking that he was slower than Wei Zheng and the others anyway, so why were he in such a hurry...
But it was also because of his carelessness that he noticed that Fang Xuanling, an old boy, had something wrong with his face——
what's the situation?
Immediately afterwards, Wei Zheng's face suddenly turned pale.
This time Li Er discovered it again.
This... hmm?
Next is Du Ruhui.
In short, within the same period of time, the expressions of these three ministers became extremely dull at the same time.
This time...
Li Er suddenly realized.
Wait, something's wrong.
Do these guys mean...
"you……"
"Your Majesty...Old Li, this..."
Wei Zheng's face was pale, as were Du Ruhui and Fang Xuanling beside him!
then……
"It's really eight hundred and sixty-four... It's really eight hundred and sixty-four!"
"this……"
At this moment, Li Er also turned to stone on the spot, with a dull look on his face...
Shocking!
It’s actually this number!
But……
Didn't Xiao Changle say this answer in an instant?
The three of them, Wei Zheng, took a long time to figure it out!
But what happened to Xiao Changle? It turned out...
It turned out that the calculation was completed almost in the blink of an eye!
This speed is at least four or five times faster than Wei Zheng and the others!
What is this concept?
Wei Zheng and the others were some of the top military, political, economic and business talents in the Tang Dynasty. Their mental arithmetic speed was more than ten times faster than ordinary people.
But Xiao Changle was much faster than them this time.
In other words, Xiao Changle’s calculation speed is hundreds of times faster than ordinary people!
But this...
This is incredible!
Li Er, Wei Zheng, Du Ruhui and Fang Xuanling, these four people simply couldn't figure it out after much thought.
How could Xiao Changle's arithmetic ability be...
Why is it so scary??
Isn’t this so scary?
While everyone was in shock, they saw Xiao Chang Le smiling proudly.
"Hehe...Dad, you didn't expect it, did you? This is calculated using the method taught by Master to Lele!"
"ah?"
Li Er and others were startled, and Wei Zheng couldn't help but blurt out, "What method? This... no matter what method is used, it can't be calculated so quickly..."
Fang Xuanling went straight into a state of despair!
"This...isn't this an immortal magic..."
"Of course not, Master said, this is called a calculation formula..."
…
Xiao Changle then explained to Li Er and others what a "calculation formula" was, and then he explained the commutative law, associative law, addition and multiplication in a show-off manner...
After saying this, Li Er and others were stunned.
Damn it, what kind of magical calculation method is this...
Li Er is fine.
But Wei Zheng and others, these people are the real top talents of the Tang Dynasty, and they don't have any profound knowledge in their minds.
But I have never seen such a convenient way to calculate numbers!
Everyone just felt confused and shocked.
So shocking!
No wonder...
At this moment, Wei Zheng and others felt amazed, because they finally understood why Li Sheng could surpass so many complex and powerful machines and tools.
It turns out that it is not just machines and tools, but also in the matter of "calculation", in this basic area, Li Sheng has already surpassed the world countless times!
This kind of thing is called a genius!
Geniuses generally learn things quickly, but in Li Sheng's case...
Wei Zheng, Fang Xuanling, and Du Ruhui could only swallow silently. How long has Li Sheng's situation lasted...
Everyone couldn't help but exchange looks.
I'm afraid this Li Sheng has some academic arrogance...
This calculation method is simply a truly magical method!
Of course, Li Sheng felt a little uncomfortable in everyone's expressions.
In fact, the invention of paper in the Eastern Han Dynasty already supported this calculation method, and after the invention of paper, it also supported the birth of an additional thing - design drawings - compared to the previous use of bamboo slips as information carriers in the Western Han Dynasty.
But because from the Eastern Han Dynasty to the Wei and Jin Dynasties, the scholar-bureaucrats in China were relatively unbearable, so advanced information technology such as paper failed to trigger changes in material civilization and start the industrial revolution...
However, how could Wei Zheng and others think of so much? For them at the moment, this is the only calculation method that is completely new and absolutely advanced.
If such a thing exists, even if they don't have any concept of "technological revolution" in their minds, they can still think of it...
In the future, it will bring huge benefits to the world.
The Tang Dynasty, China, and countless people in China will be the first to enjoy the benefits of this change!
And then when Xiao Changle saw his father and several uncles, they were stunned by him, and simply continued to start the next round of showing off skills...
"Dad, Uncle Wei, Uncle Du, Uncle Fang, what are your expressions? Lele has learned a lot..."
"Look, this one is called a linear equation of one variable, and this one... is more advanced. This one is called a quadratic equation of one variable!"
"Master said that when solving equations, you must remember that odd changes and even changes remain unchanged..."
Xiao Changle's display of skills made Wei Zheng and others even more confused.
Good guy, how many unique skills has Li Sheng learned? This method is too terrifying...
But until they saw Xiao Changle draw something called a "parabola" on the white paper and explain it in passing, Wei Zheng and others fell silent...
