These words seem to be praise, but they are full of merciless ridicule.

Every sentence pierces the heart.

As a lord who sympathized with her lords, Leah never thought of the serfs as filthy bugs, on the contrary, serfs were wealth and the guarantee of Blackstone's survival.

A lord who has no people is truly worthless.

Leah remembered the laughter of the serfs at the harvest festival, simple and simple, they didn't ask for much, just to be able to eat enough.

But what about the Holy Spirit, who enjoys the worship of the nobility and the nourishment of taxes, and the weak who really need to be saved and cared for, can only look at the statue made of gold, and they are not even qualified to come to the church.

The last vestiges of faith began to crumble, and Leah glanced at the magnificent temple and the magnificent statues from afar, and then, without hesitation, turned around.

Yes, she made the final choice.

"Leah, you're out of the cage. The wings of wisdom will take you to the sky and appreciate the true beauty. Qin Song's tone was full of gratification: "True fraternity is universal, it benefits all sentient beings, and it is full of enthusiasm in the shining crystallization of knowledge." ”

The temple and the statue began to crumble in the dream, and the boulder in Leah's heart dissipated with it, and suddenly there was a sense of relief.

"God. Leah's eyes were clear, and she knelt on one knee with the standard knightly salute: "I have seen your wisdom and am willing to believe in you and gain knowledge like Alice." ”

"The palace of knowledge does not reject a soul full of curiosity. The beauty of knowledge, like jade liquid elixir, delicacies, makes people's souls feast. ”

Leah's eyes showed a little longing: "Please give me the key to the temple of knowledge, and I will exhaust my life to explore hard." ”

"Alice has received the golden key to the temple of knowledge, and you, Leah—you will be given symbols to describe nature, and you will have unique art. It is the foundation of all knowledge and the source of all creation. ”

"What's that?" said Lia's heart with some excitement.

Qin Song paused word by word: "The symbol of nature, the aesthetics of numbers!"

It was decided to let Leah learn mathematics, and after careful consideration, Alice's current manufacturing tools rely entirely on hand kneading, and the accuracy is very poor. The first problem involved in making a precision machine is mathematics.

From Liya's skillful use of arithmetic, it can be judged that she has a certain mathematical foundation and is easier to understand mathematical theories. And she can obviously reach a better tacit understanding with Alice.

"Numeric-aesthetic?" Riah's eyes lit up, she did have a preference for arithmetic, except because of the skills necessary to be a lord, and the results through calculations would give her a sense of accomplishment.

"Yes, it is a knowledge, a wonderful art, the highest expression of knowledge. But it is ubiquitous in life and the brightest pearl in the temple of wisdom. ”

In front of Leah, a piece of parchment slowly appeared, on which were drawn ten strange symbols.

0、1、2、3、4、5、6、7、8、9、

"Leah, all the numbers in this world can be summed up by these ten symbols. The first '0' represents nothingness, which represents non-existence. ”

What is the greatest invention in Arabic numerals? Yes, it's 0. It took 300 years from 1 to 9 that 0 was coined, and many mathematicians, including Aristotle, Euclid, Archimedes, and Pythagoras, had never thought of using 0 as a number. In place of 0 is a placeholder called sifr, which does not participate in the operation.

The emergence of 0 makes expressions such as 507, 570, and 5700 clearer and clearer, and also greatly simplifies complex calculations.

"It doesn't exist?" Riah's expression was startled, and she blurted out, "If it doesn't exist, why do you need to express it?"

"Leah, it means that there is no existence. But the absence of it does not mean that it is meaningless, on the contrary, it is significant, and this is the aesthetics of numbers. ”

Leah was confused, but her eyes were fixed on the circle that represented non-existence.

The next nine symbols, representing from one to nine. Together, they form the most basic system of numbers, and you can use them to represent hundreds, thousands, and ten thousands, whatever you want. ”

From one to nine, it was very easy to understand, and Lia silently wrote down the way the numbers were written, but she was a little curious about what the expression was.

Then three strange symbols slowly emerged on the parchment, a horizontal bar, a cross, and two parallel horizontal bars.

Plus, minus, and equal signs.

"Everything in the world increases and decreases, from nothing to nothing, from something to nothing. Just like the great nature, spring, summer, autumn and winter alternate, flowers and trees sprout, grow, bear fruit, and return from fallen leaves to roots. These two great symbols, the first represents a decrease, the second an increase, and the last one represents balance and equality. ”

Qin Song incarnated as a kindergarten math teacher, telling the most simple and easy-to-understand truth with compelling words.

I have to say that this teaching method is a bit brain-burning.

Then a formula appeared on the parchment blackboard, the famous 1+1=2.

Leah, who understands the meaning of numbers and the plus and minus signs, understands the meaning of this formula almost instantly, which seems too simple, but at the same time, it has a huge impact on her worldview.

Then her thinking began to diverge, and this simple and straightforward formula could be further expanded to 1+2=3, 1+3=4, and so on.

Oh, my God!

Leah seems to have stepped into a new world, and with three simple symbols, she clearly and completely expresses the principle of increase and decrease, and quickly comes up with the corresponding answer.

This...... Is this the charm of knowledge?

Leah's heart was completely touched by the wonderful numbers.

"Then Leah. Qin Song looked at the shock written on her face and threw out a question: "Subtracting the same two numbers, behind the symbol representing balance, what should it be?"

"0!" Ria seemed to have a flash of lightning in her mind, and she finally understood what 0 meant, a number that didn't seem to represent anything and other numbers, and the addition and subtraction formula was perfectly complemented without any flaws.

With Liya's math skills and IQ, this basic knowledge is thorough at all.

"Wisdom delights and knowledge enriches. Leah, the essence of numbers, that is, the essence of nature, a truly great wisdom. ”

The simple ten numbers and three numbers made Liya a little impressed. But in the same way, more doubts arise in the heart and turn into a desire to learn.

"And what about the bigger numbers?"

"Combination!Lea, nature is the combination of all things, and the largest number you can think of can also be freely combined by these ten symbols. ”

Three numbers appear on the parchment: 10, 101, 1024.

"A number greater than 9 is a combination of the two smallest numbers. The great 0 pushes the 1 forward and gives it a whole new meaning. ”

Then a new formula appeared on the parchment: 10 + 1 = 11

Liya was completely stunned, not because it was too simple, but because it was simple and shocked her from the heart.

It can be like this!

How can it be!!

That greater than 10 can be expressed as 11, 12, 13...... 19。 What's next? Bigger numbers, wouldn't we be able to continue to give new meaning to zero?20, 30, 40!!

What's even more surprising is the formula, which is upgraded on the basis of 1+1=2, 10+1=11, then 10+2 equals 12!

Even if she is new to this symbol, Leah can easily calculate the accurate result!

This kind of terrible efficiency, simple expression, has left the of the cumbersome counting and counting seconds.

Looking at those numbers and formulas, with strange coordination and beauty, and with flawless logic, they constantly hit Leah's heart.

"Leah, this is just the simplest number, not even the tip of the iceberg. But it is the source and foundation of everything, remember them, understand them, and you will gain great wisdom that has never been seen before in this world. ”

The distant voice gradually dissipated, and Leah stared blankly at the parchment in front of her, these symbols, these formulas, opened the door to a new world for her!
