"Why is Childe here, have you already rested?"

Hearing the kobold's report, the fox girl and Mr. Ram hurriedly got up to greet them, the orcs were really very, and they were saved by Lin Chen's chewing gum, and they were all very grateful to Dade.

Lin Chen had never been respected, and he was a little unaccustomed to it, but he quickly diverted his attention, and cast his gaze on the ledger on the table, seeing the dense black vertical bars on it, the doubts in his heart reached the peak at once.

"What are you guys doing here? Is this your ledger? ”

Lin Chen approached the table and looked at the ledger carefully, Nima, what the hell is this, the whole ledger is full of things that look like Arabic numerals '1', what kind of account book is this? Where is the tent? Where are the numbers? How is it so special as a one-year-old child's exercise book after learning 'vertical'?

Hearing Lin Chen's question, the fox girl and Mr. Ram glanced at each other, and a little reserve and pride rose in their expressions, Mr. Ram touched his goatee quite complacently, and said with a smile: "It is reasonable that Childe does not know these, this is the technique of painting numbers that we have just invented in the Scarlet Prairie in recent years, not to mention outsiders like Childe, even in the Scarlet Prairie, those who can know these are very few smart beasts." ”

Lin Chen was even more confused: "The art of drawing numbers? What is it for, does it have anything to do with settling accounts? ”

Nima's, what kind of ghost account are you drawing a bunch of ghost drawings on the ledger? Can this thing be calculated? What's in the orc's head?

"Hehehehe." The fox girl covered her mouth and chuckled, and after laughing, she gently saluted Lin Chen: "It is reasonable that Childe does not understand, after all, the way of arithmetic is unfathomable, and the art of drawing numbers is even more mysterious and profound, those who do not know the number cannot understand it at all, and it is natural that Childe does not know how to read and understand, but Childe does not have to mind, you must know that there is no one in a thousand who can read the number among my orcs, and there is no shame in the fact that the son does not know the number, if the son is interested, I can teach the son to know the number, and Mr. Ram must also be willing." ”

Nima, are you scolding? Although Lao Tzu is not a high-achieving student, he has been studying for more than 20 years, and he is a second-class graduate. Why do you want to teach me how to count? I'm going to Nima!

Lin Chen only felt a burst of blood surging, rushing straight to his brain, his face instantly turned red, not red, no, he was so angry, he was actually despised as illiterate by several orcs in primitive society, no, it is more terrible than illiteracy, illiteracy is just illiterate, why do you say that Lao Tzu is illiterate.

The day dog is gone!

Lin Chen couldn't bear it anymore, and coughed heavily: "Who said that my son doesn't know how to count, one, two, three, four, five, six, seven, eight, is it that this son doesn't understand such a simple thing?" ”

"Gong, Gongzi, you, you actually know how to count?" The fox girl's voice trembled, her face was full of incredulity, and Mr. Ram on the side also opened his mouth, as if he had seen a ghost.

Go Nima!

Lin Chen scolded again in his heart, what the hell is your expression, Lao Tzu's ability to read numbers is not very normal, don't say that Lao Tzu, a second-class graduate, even if he is a primary school student, is especially able to read numbers.

"My son naturally knows how to count." Lin Chen snorted slightly, expressing his dissatisfaction.

"I'm sorry, I'm sorry, Childe, we didn't mean that." The fox girl apologized again and again, and then explained: "It's really too few orcs who know the number, don't hide it from the child, in our blood-colored plains, often it is difficult for a tribe to appear a beast that knows the number, even if it is the fox clan and the sheep clan who are good at wisdom, it is only among the hundreds of tribes that there can be a beast that knows the number, so we are a little forgetful." ”

"Childe, you are so powerful, you actually know how to count, the medium-sized kobold tribe I was born in has thousands of beasts, but there is not a single one who can count." The kobold's eyes were full of worship and reverence, just like an ordinary person on earth who had met a great scientist, no, a hundred times more exaggerated than that, it was like a fanatic believer who had seen the true God.

Lin Chen was speechless, it's very common to know a number, do you want to be so exaggerated? But there is not a single one in a thousand people who can count, this, this is really too backward Nima.

No longer pursuing the attitude of the fox girl and the others, Lin Chen once again turned the topic back to the strange ledger, this time the fox girl explained in detail, but this explanation, Lin Chen was immediately shocked.

"You mean, you count by drawing verticals? One, two, three, four, five, six, seven, and eight keep checking down, and you rely on this to check the accounts? ”

Lin Chen looked at the fox girl and Mr. Ram almost dumbfounded, this, such a reckoning, it was just stupid to cry.

"Of course, is there a better algorithm for Childe? Doesn't Childe think this method is very clever? Hundreds of years ago, we all use our fingers and toes to settle accounts, but the fingers and toes add up to not much, sometimes even to gather thousands of people to check the fingers and toes, that is not enough, a few decades ago a wise man invented the knot rope counting, that is, to knot the rope to calculate the number, but that is also very troublesome, and the art of drawing numbers is much easier than the first two, a ledger can draw tens of thousands, or even more. ”

The fox girl said very seriously, and Lin Chen was about to collapse, inserting his fingers and toes, and gathering the whole clan, alas, mom, you are so talented, I have heard of knotted rope counting, but that Nima is what the earthlings did thousands of years ago, this, this Nima, you are really backward and desperate.

As for drawing tens of thousands of verticals on the ledger, Lin Chen really didn't dare to agree.

"Do you know how to count?"

Lin Chen flipped through the account book on the table, and found that there were brackets in addition to 'vertical', and a trace of doubt couldn't help but arise in his heart.

"Count? yes, weren't we just counting? Didn't Childe find out? The fox girl glanced at Lin Chen suspiciously, pointed to the brackets on the account book and said: "This is the arithmetic, Childe, please see, there are one two, three, four, five and six numbers in this bracket, this is the price of a piece of dried rabbit meat, and this bracket has one two three four five, five numbers, this is the price of a smaller piece of rabbit meat, and then we start with the first bracket, one two three four five six, check the first bracket and then check the second bracket, seven** eleven, you see, this is calculated out, it is eleven." ”

Lin Chen's face twitched, and he had a feeling that he couldn't bear to look at him directly, Nima, that's how you count? Count five plus six, and you have to make eleven 'vertical', and then check from one to eleven, this, this Nima can also be called arithmetic?

You really need to learn addition and subtraction.

…………
