Datang: I am so happy to marry a disfigured princess!

Chapter 193 When I bring up modern mathematics, how will you respond?
Hearing this, Lin Heng smiled.

How big it is is naturally beyond your imagination.

Although the arithmetic of the Tang Dynasty had developed to a certain level and had a profound impact on the arithmetic of later generations, the arithmetic of later generations integrated this knowledge.

Let’s just say that Lin Heng’s book almost synthesizes various advances and breakthroughs in mathematics over the years. After all, this is the cornerstone of mathematics!

In the feudal era, emphasis was placed on rule and education, and there was some mathematical calculation, but its application was still very narrow, let alone developing it into real mathematical research.

Li Chunfeng has also made great achievements in the research of arithmetic. For simple arithmetic problems, you can't see the difference, you can only see the speed, which proves nothing.

"Then I want to see how Li Chengwu wants to compare."

When Li Chunfeng heard this, he smiled and said, "That's the simplest thing. I want to see how what Consort Lin did in terms of calculations is different from what he does now."

Lin Heng nodded: "No problem, then you and I will each come up with the questions and we will know at a glance."

The two quickly brought paper and pen, and Li Chunfeng smiled and said, "Then I will give the question first."

He thought for a moment, then showed a meaningful smile.

"One plus two plus three..."

Lin Heng raised his head, and the latter said with a smile: "I haven't finished talking yet, Prince Consort Lin, don't worry."

"continue."

"Add four plus five...keep going in this order, and the total will be added to fifty."

For Datang, the number sequence problem had just been broken through. Li Chunfeng had already guessed that ordinary arithmetic would have no effect compared with Lin Heng, so he might as well go directly to Wang Zha.

The method to solve this Taoist technique has been researched and developed with a lot of professional knowledge in mathematics. If you stupidly add up one by one, you can know the level without even looking at it.

Lin Heng did not write, but raised his head and said in surprise: "It seems that Li Chengwu is quite confident in his ability. It's this kind of problem that comes directly to him!"

Li Chunfeng chuckled: "Looking at Lin's consort being so calm, he must already know the answer."

"One thousand two hundred and seventy five can be added up in the most common way. Of course, you can also add up at the end, such as one plus fifty, two plus 270, so there are 49 25s, and then you can get the result by multiplying them together."

Li Chunfeng heard the words and nodded: "I can't believe that Lin's consort can find the rules so quickly. He is indeed a strange person. Yes, we only discovered this method recently. We found that this method can be applied to many In terms of it, it’s very simple.”

Hearing this, Lin Heng chuckled.

"I still have a solution, a simpler method, and a simpler way to calculate the result."

Li Chunfeng asked curiously: "What method?"

Lin Heng then said: "Add the first term and the last term, multiply it by the total number to be calculated, and then divide it by two. This way you can get the result directly, and there is no need to do more complicated calculations."

Hearing this, Li Chunfeng was stunned for a moment: "What Prince Consort Lin means is to use the number of one plus fifty to multiply the total number, which is fifty, and then divide the whole number by two?"

Lin Heng nodded. Seeing this, Li Chunfeng picked up a pen and paper and thought about it for a moment, and then his eyes lit up.

"It does seem that the results can be obtained faster in this way, and it seems that it can be applied to larger numbers?"

Lin Heng explained with a smile: "In fact, it is the same as the law discovered by Li Chengwu, except that the law is summarized and used in multiplication and division. In this way, no matter how big the number is, it can actually be calculated."

The abbreviation is the general formula of the arithmetic sequence. This is the crystallization of culture!

Upon hearing this, Li Chunfeng immediately made a calculation of one plus two plus three plus one hundred, and then used Lin Heng's method.

"One plus one hundred, multiplied by one hundred, right...and then divided by two five thousand and fifty? Is it really that simple?"

After finishing the calculation, Li Chunfeng looked at Lin Heng in astonishment: "How did you discover these patterns? Is it possible that Lin's consort also delved into calculations?"

Lin Heng said slowly: "This is not calculation, this is called mathematics. It is a formula that summarizes the rules we discovered. In this way, the rules will be reflected and more essence." "Not just this, Soon, some of the common patterns in our lives, such as the sun rising in the east and setting in the west, and the changes in the four seasons, are actually regular. As long as we find the method and then use mathematical methods to explain it, it is mathematics."

After hearing this, Li Chunfeng was stunned for a long time and seemed to have some insights.

After a moment, he still sighed: "This is easier said than done. There are only a handful of people in the Tang Dynasty who study these things, and no one thinks these things are useful. Today's calculation results are thousands of years old. Our ancestors worked hard to get here, and it’s not that easy.”

Lin Heng chuckled and said: "If these things can reflect their value and be recognized by the public, won't there be more people studying and researching them?"

"What does Prince Consort Lin mean?"

"If something is only reflected in books, no one will learn it, but if it is reflected in real life, many people should be interested."

After hearing this, Li Chunfeng thought for a long time, but he still didn't have a clear direction in his mind. I'm afraid he will have to think about this for a while.

"Consort Lin, it's your turn to test me."

Seeing Li Chunfeng's confident look, Lin Heng just thought of something.

"If you test me on the method of accumulation, then I will also test something similar. For example, the difference between each of the two numbers one, two, four, and eight is two. You just need to calculate a number."

Li Chunfeng was stunned when he heard this. Does it count as a multiple?If the number is smaller, I'm afraid I can still calculate it, but I don't even know how big it is, right?

How does this count?
"Consort Lin... Could it be that you are taking revenge on me? How do you calculate this?"

Lin Heng explained with a smile: "Look, the ratio of each number to the previous one is two. Isn't this a rule?"

If you test me at the same level, then I can test you at the same level, right?
I haven't asked you to add up the numbers yet, I've just asked you to figure them out.

Li Chunfeng looked confused. He stared at the numbers and thought for a long time, but still had no clue.

Lin Heng smiled and said: "Look, if these numbers start from the second item and there is a ratio between them and the first item, can you treat it as an unchanging quantity?"

Li Chunfeng nodded.

"Then for the third term, are there two such ratios, that is, the square of this ratio?"

The development of mathematics in the Tang Dynasty was a peak in history, and the concept of power had long appeared. At that moment, Li Chunfeng understood it instantly, and his eyes suddenly lit up.

In other words, by multiplying the first number by this existing power, can we directly get this number?
"The third term exists to the power of two, which is two to the power of two. That term is two to the power of 49 multiplied by this number, that is."

Li Chunfeng was confused again. The first number was two. What is the fiftieth power of two?

Can this number be calculated?

Seeing this, Lin Heng also smiled and said: "As long as you understand the idea, this number is too big, and generally speaking, it cannot be calculated at that position."

Li Chunfeng breathed a sigh of relief, but there was a feeling of enlightenment in his mind.

This feeling aroused an unusual desire for knowledge in his heart.

Whether it was Lin Heng's previous method of calculating the accumulation or this number, it all made him feel refreshed, and he always felt as if something was about to break through.

This is the law. I’m afraid there are many more laws between numbers. If there are rules for accumulation, does there also be a corresponding rule for multiplication?
Li Chunfeng immediately held up his hands and said, "I am willing to bow down to you. The calculations taught by Consort Lin are indeed extraordinary!"

Lin Heng was helpless when he saw an extra small component in the system space. It was a bird box for the system!
Lin Heng waved his hand: "I just mastered these rules. I believe you can use them in many more places than me."

Li Chunfeng nodded: "If you count, I think Prince Consort Lin must have gone much farther than me. If possible, I would like to ask Prince Consort Lin to give me some advice in the future."

"Of course you can. Just give me some advice. Let's communicate with each other."
