The road to technology

After talking about these, Yue Yuanzhou began to talk about the definition of length units, weight units, angles, ninety-nine multiplication formulas, and mixed operations.Followed by one to three-digit multiplication and division, simple equations, polygon area, factors and multiples, fractions, percentages
Then there are positive numbers, negative numbers, and simple geometric definitions.

After all, monks are monks, and they listen and think with their primordial spirit, so even though they don't even have textbooks, they don't feel a bit strenuous when Yue Yuanzhou keeps talking non-stop.

On the contrary, each one of them felt very easy.

The monks who feel simple are almost contented: "Well, the round one, the same length in the plane! It's really wonderful, this way of counting is not as difficult as imagined."

Once this person felt that things were easy, he began to drift away. Everyone felt that they could understand what they heard with only half of their attention, so some monks started to listen to the lectures while practicing.

Yue Yuanzhou naturally noticed it, but he didn't care about it, he just talked from shallow to deep.

Rational numbers, irrational numbers, integers, equations, and other concepts appeared on the big screen one after another, followed by the four arithmetic operations of these numbers, and then algebra, which led to linear equations in one variable, solution of equations, and linear equations in two variables.
After talking about algebra for a while, I jumped the channel and started to talk about the corresponding plane geometry. When talking about plane geometry, I mentioned a few words about surface geometry, and then returned to equations and inequalities.

Every concept Yue Yuanzhou explained very carefully, but he just talked like this, never stopped, and did not finish the get out of class.Gradually, axis alignment, statistics, fractions, factors, square root, quadratic radical, Pythagorean, etc. came into play one after another.

At this point, some monks have realized that the content is gradually deepening, and have adjusted from the state of listening to lectures while practicing to listening carefully, but some monks still find it easy.

At this time, Yue Yuanzhou had finished talking about the content of his nine-year obligation, so he paused for a while, and did not continue talking.

Instead, he changed the subject and said: "What I have said before is the simplest introduction to numbers, and it is the content of the decimal system of numbers. Then, let's talk about binary."

"You all know that one is born and one is two, but they don't know that one is born of infinity, so it is called Taiji, Taiji gives birth to two appearances, two appearances give birth to four images, and four images give birth to gossip." Yue Yuanzhou said, appearing on the big screen Draw a simple graph.

He pointed to the black and white above the word 'Tai Chi' in the graphic: "This is Yin, this is Yang."

Then point upwards to the one black and one white pattern on the black corresponding to 'Yin': "This is Taiyin, and this is Shaoyang." Moved to the right: "This is Shaoyin and Sun."

"This is called Taiji, Liangyi, Sixiang, and Bagua!"

While Yue Yuanzhou was talking, the graphics also displayed text labels. He then pointed upwards: "These are Kun, Gen, Kan, Xun, Zhen, Li, Dui, Qian, and upwards are their corresponding symbols."

After getting all the monks to recognize this figure, Yue Yuanzhou looked forward, looked at the monks sitting upright in the small cubicle, and said: "Therefore, Kun Zhe is black and black, and the hexagram symbol is Yin Yin. Gen Zhe, black Black and white, the hexagram symbols Yin and Yang. Kanzhe, black and white black, the hexagram symbols Yin and Yang. Sunzhe, black and white, the hexagram symbols Yin and Yang. Shocker, white and black, the hexagram symbols Yang and Yin. Lizhe, white and black, the hexagram symbols Yang, Yin and Yang. For those who exchange, white and black, the hexagram symbolizes yang and yin. For those who are dry, they are white and white, and the hexagram symbolizes yang and yang.”

Speaking of this, there was a look of excitement among the monks, Yue Yuanzhou felt it, so he followed the direction of the source and looked in the past.

Oh~ it's Fuxi!

That look was indeed listening vigorously, but Donghuang Taiyi's state in the cubicle next to Fuxi was much worse.

Yue Yuanzhou smiled lightly, waved his hand towards the big screen, and a congenital gossip figure appeared next to the figure just now, and then he said: "If there is a yang line, it means existence, and if there is 1, there is no yang. , and Wu Ji is 0, so the Kun Gua is 000, and the Gen Gua is 001.

"If the area of ​​the rectangle in the Eight Diagrams is 1, then the area of ​​the Liangyi is 4, and the area of ​​the Sixiang is 2. In this way, the area of ​​the same line of the 'Liangyi', 'Sixiang' and 'Bagua' can be added. Get the decimal system corresponding to each hexagram in the gossip, this is the method of binary and decimal conversion.

故坤卦为000，则其十进制数为4x0 2x0 1x0=0。艮为001，其十进制数则为1。坎为010，其十进制数为2，巽011则为3以此类推，反之亦然。故曰，阴阳八卦者，筹算之道也。”

After talking about some of the most basic concepts of binary, Yue Yuanzhou then began to explain the way of calculating innate gossip.

In fact, he still wants to talk about the sexagesimal system, but now Xi He has not yet born ten days, so there is no place for ten heavenly stems, and Chang Xi has not yet born December, so there is no theory of twelve earthly branches.

There are no celestial stems and earthly branches, so the sexagesimal system composed of celestial stems and earthly branches is naturally not suitable to talk about.

It is precisely because of this that the calculation method composed of gossip and celestial stems and earthly branches cannot be extended, and these can only be left to these monks to explore by themselves.

However, even if it is only the binary calculation of gossip, it is profound enough, coupled with the corresponding conversion with the decimal system, etc., it almost immediately enters another level of difficulty.No, Yue Yuanzhou has only been speaking for more than 100 years, and some monks began to feel drowsy.

Except for Fuxi.

Yue Yuanzhou noticed that Fuxi became more energetic the more he listened, his piercing eyes said everything.

On the other hand, Donghuang Taiyi who was next to Fuxi already showed a little bewildered expression on his face. Of course, Donghuang Taiyi was still much better than other monks.But who let him sit next to Fuxi? There is no harm without comparison. This is the so-called scumbag and bully.

And when Yue Yuanzhou was talking about the way of numerology.

The Zixiao Palace on the other side has also ended its second lecture of 3000 years, and the method of the three corpses has been explained.

It's a question and answer right now.

Lao Tzu relied on himself to sit on the first futon, and first asked: "Dare to ask Teacher, what method should we use to prove the Tao?"

For some reason, Hongjun didn't seem to want to pay attention to Lao Tzu, but at this time it was indeed time for question and answer, and there were eager eyes from below, Hongjun had no choice but to say: "There are three thousand roads, all of which can prove Hunyuan. As for There are three ways to prove the Tao. One is to prove the Tao with strength, which is to use one's own physical strength to open up a world in the boundless chaos. Created the world from the beginning to the end."

Hongjun was right. What Pangu proved was indeed Hunyuan, but he didn’t say that Pangu wanted to prove Hunyuan beyond the prehistoric world in one step, and he didn’t know that Pangu actually used a method to break through ten thousand ways. It's only when the certificate is mixed.
