Chapter 262 How Can Numeracy Be So Simple

Chapter 250 How Can Numerology Be So Simple

The two guys dared to play smart in class, Liu Xie would not let them go, and immediately wrote two numbers on Zhuge Liang's side, 777 and 666, and wrote 888 and 555 on Sima Yi's side.

Then he said: "Quickly calculate the 777 times of Zhuge Liang's 666, and quickly calculate the 888 times of Sima Yi's 777. Whoever figured it out last will be punished by the ruler. Within a moment, neither of you will be punished together. The following students, whoever calculates it within a moment, will be rewarded, and there will be a big reward."

No one thought that Tianzi would come up with a question suddenly, and it was such a difficult multiple question, it gave me a headache just looking at it, how easy it is.

Although they have learned numerology, the numerology in this era is actually superficial. They can do addition and subtraction. There is no such difficult multiplication and division algorithm in Chapter Nine Arithmetic.

How could it be possible to calculate it for a quarter of an hour, and it is impossible to calculate it without half an hour. At this moment, everyone showed a touch of sympathy for Zhuge Liang and Sima Yi, telling you two to show off, let's hit the gun this time.

"Dezu has a way to calculate." Someone asked Yang Xiu in a low voice. Anyway, he is also one of the three top students in the college.

Yang Xiu shook his head with a constipated face. He didn't have a deep study of numerology. He dared to be the second in the collection of epic poems, and no one dared to be the first.

He hasn't forgotten the incident of being warmed by candles in the official last year, just wait, these two guys are also going to be unlucky.

Zhuge Liang and Sima Yi stood on the podium, thinking hard, doing mental calculations, their brows were all frowning. It was obvious that the amount of the question was too big to calculate.

Numerology before the Wei and Jin Dynasties in ancient China was criticized on this point. There was no definition of any mathematical concept, and no derivation and proof was given. Therefore, once a single huge mathematical calculation is calculated, it is basically difficult to start, and it takes a lot of time. Accumulated over a long period of time to calculate.

After all, the algorithms of the ancients are all explained in words, without a specific analysis process, most of them have only one result, so it is very inconvenient to learn.

A moment passed quickly, and neither of them could figure it out. This was a bit brain-consuming, and they couldn't figure out the correct number for a while.

"Your Majesty, the time has come."

Zhuge Liang and Sima Yi sighed as they watched the funnel timer go by for a moment. After all, they couldn't calculate it in a moment.

All eyes were on Liu Xie, to see what he could say and how to figure it out.

Liu Xie didn't speak, and asked the guards to clean the blackboard. He was not in a hurry to solve the two high-quantity math problems just now, but asked them to memorize the nine-nine multiplication table (it is said that there was a nine-nine multiplication table in China during the time of Emperor Fuxi. There are also historical materials that prove that the Spring and Autumn Period has become popular. Anyone who has read the book will know that it is recorded in various classics such as "Xunzi", "Lu Shichunqiu", "Sunzi Suanjing", etc., so those who traveled through Tang, Song, Ming I won’t say much about the traveler who pretends to be a nine-nine multiplication table).

Then Liu Xie wrote out the ninety-nine multiplication table with Arabic numerals.

This is very intuitive, impressive and vivid on paper.

It turns out that the multiplication table can be expressed in this way.

Then Liu Xie first listed the addition, subtraction, multiplication and division, and wrote down the simple number of digits.

Now everyone was even more enlightened, and found that this strange symbol had a magical effect, which made people's eyes shine. It turns out that arithmetic can be expressed so easily and conveniently.

Those sitting here are not idiots. Simple addition, subtraction, multiplication, and division are easy to understand, and they are clear once you do the calculations. Everyone applauds.

It turned out that numerology can be so interesting, so it is not boring. Thinking of the numerology learned before, everyone regretted seeing the emperor too late. They spent a lot of effort in vain, but they didn't learn much. It was really a waste of time.

Even Sima Wei and Cai Yong secretly admired them.

"Everyone is optimistic. Now let's come to a more difficult one. Tens digits are multiplied by ones digits, such as 77 multiplied by 6, which can be split into two ninety-nine algorithms that multiply six times seven, six seven 42, six seven 42, two 42 is placed horizontally like this, and then added vertically, it is 462." After Liu Xie finished writing, he looked at the crowd and let them see the blackboard clearly. Six times of 77, which can only be calculated by a genius, was calculated in an instant.

Simple and intuitive, clear at a glance.

"Is there anything else you don't understand? No, we are calculating 77 times of 66." Liu Xie continued to write: "Just now everyone learned 77 times of 6. Now we can calculate like this, split 66 into two 6, Multiply with 77 respectively, so there are two 462, which are arranged horizontally, and then added vertically, so we can get the answer 5082."

boom!So fast, 77 times of 66 can be calculated at once.

Everyone couldn't believe it, how could it be so fast, how could arithmetic be so easy, so simple, just write this strange symbol, add numbers, and the following answer can be calculated immediately.

Strange, peculiar, astonishing, but at the same time, it seems that a new world has been opened, as if something has been grasped, some truths that have never been seen before.

"I don't know if everyone understands."

"Understood!" If you can't understand this, you don't need to go to school. They are all elites from various regions, and they all have flexible heads.

"Okay, let's invite a classmate to come up and make a 777 6 times." Liu Xie smiled and pointed to the clever boy in the front row.

The man came up happily as if he had won a treasure. After finishing writing, he read it carefully and checked it. Liu Xie nodded and praised that it was right. He rewarded everyone with something as a reward.

"We don't count the 777 times of 66, whoever comes up and writes the 777 times of 666 for me." As soon as Liu Xie finished speaking, the crowd below shouted to perform on stage.

The truth has been grasped, the skills are only a little bit, and they are almost learned. The 777 times of 555 should not be too simple. It can be calculated in a few breaths. How can such a majestic opportunity be missed.

So he fought for it first, Liu Xie ordered a pleasing one, and the man immediately solved the answer according to the gourd drawing.

777 times 666 is 517482.

"Okay! Let's say, is this classmate right?" Liu Xie stared at Zhuge Liang and Sima Yi, and then asked, the following are all right, Liu Xie naturally knew it well, and it was also a reward, which made people go down.

Then he said to Zhuge Liang and Sima Yi: "Are you two going to forget it now?"

"Student meeting." Zhuge Liang and Sima Yi stood on the podium for so long, they had listened to Dong long ago, and naturally understood the emperor's intentions.

The person in front of him is not only the teacher, but also the emperor, even though he seems to be the same age as the two of them, but together with this arithmetic, he is much more famous than them, such an easy-to-use method should be regarded as a big man.

Liu Xie still smiled, nodded and said: "Very good, I think the two of you are closest to me and can hear you most clearly, so now you two are willing to accept the punishment."

Sima Yi was the first to say: "The students are poor in knowledge, I would like to punish you."

Sima Yi behaved respectfully and respectfully, without any complaints. Liu Xie took a closer look and found that Sima Yi's neck was extremely long, like a giraffe. He couldn't help but think of Cao Cao's evaluation of Sima Yi. Without moving, the head can turn 180 degrees.

Sima Yi had been stared at by Liu Xie for a long time, and he felt inexplicably guilty. For some reason, he could always see a kind of fierceness that was not hidden in the eyes of the emperor. There is a smile on my face.
