was still staying in the warm long room of the priest, warming around the charcoal pile, and by the way, Lurik, who was busy calculating with the light on the wooden board, directly stopped the work in his hand.

He suddenly looked at the priest Veria, who was wearing a deerskin and sitting cross-legged peacefully in a meditation posture, and asked loudly, "Grandma!"

"Huh? Are you hungry? My child." Vilia suddenly opened his eyes.

"One thing! I want to know that this year is the real winter!" Suddenly, Rurik felt that his words were not rigorous, and then asked: "This year is our Hanukkah day. Which day is on the calendar?"

"Are you asking this? Boy, have you already figured out what the result is?"

"Yes! If you can tell me the exact Bright Festival, I will quickly calculate the result I want, and I won't have to measure the shadow tomorrow."

"It's December 28th, my child."

Villa quickly cheered up. She is indeed a quiet observer during this period. She has witnessed Rurik showing many amazing behaviors.

What surprised Villa most was that she saw that the child was actually using an oriental digital system on the wooden board!

According to Veria's understanding, it is a number invented by people living in a hot and deserted world in the far east. It is very different from the Roman number system. It is undeniable that the ancestors of the Ross people have encountered other people with special clothes. They were businessmen from afar, claiming to be from a great country in the far east.

They claim to have done a lot of trade with the Romans, and they are willing to open up new business routes to the northern icy land.

Those strange people are real, but after they exchanged silver for some deerskin and seal skins from the Ross tribe a long time ago, they never appeared again.

But they left at least something. When Veria was young, he was fortunate enough to learn about another digital system and strange rumors about those weird people.

what! Veria could not think of his youth.

At that time, she was really unique among the tribe. She didn't have a huge desire for marriage, as if she should be a person who worships Odin, a back-up for the future Valkyrie, and must remain pure forever.

Villa very much believes in the myths told by his parents, but now his parents have passed away, and he has become the oldest person in the tribe.

Villa's studious spirit made her a wonder of the tribe. Thanks to this studious, she knew the most knowledge and eventually became the head of the priest.

Seeing the studious Rurik, Villa couldn't help but think of his youth.

She couldn't think of the many things that Rurik showed in front of her during this period. She couldn't make a reasonable explanation. She really could only believe that Rurik was clearly showing a miracle.

Of course, this miracle is not infinite power or invulnerability, but a huge innate knowledge.

As the head of the priesthood, Velia is always in chaos. Only when she has truly witnessed Rurik's talent, she has lost her attitude many times.

I told Rurik the exact date, and the child I saw wiped a few wooden boards with a coarse cloth and started a new calculation. Yes, those "Oriental numerals" and some other symbols that are not understandable are used throughout the calculation, and Roman vocabulary is vaguely mixed in them.

Finally, many problems weighed on Villa's psychology, and she finally couldn't help it.

"Ruriek, my child. Do you understand the Oriental numbers you use now?"

Suddenly, the charcoal block that was cut into a pen shape in the right hand of Rurik's immature child fell off. He was startled, and he didn't know how to answer.

"Don't be nervous, there is nothing to be nervous. You are a child blessed by Odin, and your body is full of miracles."

What can Lurik say, he was shocked that it was not Veria's suspicion of the "Arabic numerals" he used at all, but Veria knew that they were some numbers and was named "Oriental Numerals".

This fully shows that Veria knows what he wrote! In other words, in the Ross tribe of Scandinavia, someone actually understands the number invented by ancient Indians tens of thousands of kilometers away!

Villa can only use miracles to describe Rurik's surprise, and she is also very happy to share her past.

She came up with a very reasonable explanation, and Rurik, he really can only claim that knowledge is innate.

So, the Vikings of this era have had close exchanges with people in Asia? Rurik was curious.

I am afraid this is not the case. The two very far apart ethnic groups did have exchanges, and apparently they did not have a larger-scale impact on each other.

Rurik was very emotional, he felt that it seemed that the Ross tribe had forgotten another way. It is said that since the tribe can advance all the way to Novgorod, it is logical to enter the upper Volga River and directly land in the coastal areas of the Caucasus Mountains after entering the Black Sea. Eventually, it is also logical to contact the Asian desert peoples.

In theory, it is feasible. The reality is in front of us. Only the elderly Veria priests of the entire Ross tribe have a certain concept of the powerful desert nation.

For example, Veria specifically claimed that they were men in black with yellow skin, and they were completely different from the Romans in black that they had encountered. The yellow-skinned people in black always wear huge headscarves, and they all wear huge black beards, just like the big beards that the men of the Ross tribe like to continue.

They are just some businessmen who exchange some strange and wonderful things that are said to come from more distant places in exchange for some fur.

Based on these few words of description, Rurik immediately thought that what Villa said was the big food in black.

Lurik knows the basic context of historical development very well. In 828 AD, the black-clothed food was in its heyday!

The influence of a country's prosperity will be multifaceted, for example, business and trade will become developed. Since the big food in history is willing to trade with Jutang via the Silk Road, they will naturally try to go north to trade with the Vikings in the extreme north.

Since it is a trade, the digital system of the habit of eating in black will naturally collide and communicate with the Roman numeral system.

Objectively speaking, the digital system that was born in India, because the writing logic is easy to clean, and the number symbols are simple to label, it will eventually become a global digital system. I am afraid that it has this potential from the beginning.

Lurik simply wrote all modern number symbols from 0 to 9 in charcoal on a wooden board. He also enumerated larger numbers, in a purely decimal superimposed counting method, using this number system to express clearly and simply.

I have to say that this modern digital system is more advanced than the Viking's inherent. Veria is a discerning person. She not only understands this, but also realizes that it is more advanced than the Roman's.

"My child, are people in the far east using such numbers?" Veria asked in surprise.

"It's true, at least those yellow-faced and black-clothed people you encountered, they are just like that."

When it comes to this level, Rurik has been unable to control his emotions. He is eager to show all the basic mathematical things he knows in front of his "year-old friend" Veria.

Rurik even pointed out the use of symbols for addition, subtraction, multiplication and division. UU read www.uukanshu.com for fear that Veria could not understand it. He also deliberately compiled some seemingly naive but very realistic arithmetic problems to prove his own set. The superiority of "basic tools of modern mathematics in the 21st century".

Everything was as Rurik had estimated. Veria's heart was strongly shocked, and his aging body began to tremble with excitement.

Because Rurik uses a method that the people of the Rus tribe know very well, bringing the "new mathematical calculation tool" into the case of commodity trading.

For example, he drew the shape of a sheep's head on a wooden board, and put a number "6" on the front of it, followed by a plus sign, and then drew a deer antlers with a number "2", when he marked the equal sign again , And finally write the number "10". That is to say, in a simple and clear explanation, six sheepskins plus two reindeer skins are equal to ten silver coins.

Lurik cited three examples in a row. Not only did Veria fully understand it, she also had to admire the child's mathematics ability further.

Because in a sense, the businessmen of the Vikings have a natural gift for mathematics.

Rurik has understood this, and he also understands the very complicated price system of goods in the tribe. He also understands that no one has ever interfered with the economic development of the tribe. Everything is the spontaneous trade behavior of many merchants, which has created the current relative stability. Prices-that is the so-called "invisible hand".

In the barbaric era, the people of the far north were full of barbaric habits. They went back to plunder the wealth of other hostile tribes, and they also marked prices for all the things they controlled, even...

Until the enlightenment surging, a small group of talents in Europe took the lead in awakening. They got their own insights from the Bible, concluded that human life is priceless, and actively advocated it. In the end, the world finally reached this consensus.
