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...

It's over.
