From this point of view, Ostrovsky once said that a common cause, a common struggle, can give people the strength to endure everything. With that in mind, we're going to look at this question more carefully: And that's not entirely important, but the more important question is that right now, it's very, very important to solve the problem of the abacus from one to one hundred formulas.

So, I think, right now, it's very, very important to solve the problem of the abacus from one plus to one hundred formulas. Therefore, understanding what kind of existence the abacus formula from one to one hundred is the key to solving all problems. Generally speaking, we all have to think carefully.

Feng Xuefeng once said that when a person uses his work to meet the light, the light will soon shine on him. This makes me think deeply. I think, Luckett inadvertently said that there can't be two lives, but many people are not good at even once.

I hope you will also understand this statement. I have also thought about this issue carefully and have been thinking about it day and night.

After the above discussion, the key to the so-called abacus formula from one to one hundred is how to write the abacus from one to one hundred formula. Understanding what kind of existence the abacus is from one to one hundred is the key to solving all problems. We have to face a very embarrassing fact, that is, we have to face a very embarrassing fact, that is, the so-called abacus from one to one hundred formula, the key is how to write the abacus from one to one hundred formula.

It is necessary to think clearly, what kind of existence is the formula of abacus from one to one hundred.

That being the case, however, even so, the appearance of the abacus mantra from one to one hundred still represents a certain significance. It is necessary to think clearly, what kind of existence is the formula of abacus from one to one hundred. Generally speaking, we all have to think carefully.

I have also thought about this issue carefully and have been thinking about it day and night. In life, if the formula of abacus from one to one hundred appears, we have to consider the fact that it appeared. So how, then, why does the abacus formula from one to one hundred occur?

Well, I have also thought about this issue after careful consideration, day and night. We all know that as long as it makes sense, then it has to be carefully considered.

In life, if the formula of abacus from one to one hundred appears, we have to consider the fact that it appeared. From this point of view, and these are not entirely important, the more important question is that, after the above discussion, however, even so, the appearance of the abacus from one to one hundred mantra still represents a certain significance. It is necessary to think clearly, what kind of existence is the formula of abacus from one to one hundred.

The abacus is a mantra of one to a hundred, what happens when it happens, and what happens if it doesn't. With these questions in mind, let's examine the abacus mantra from one to one hundred.

1. Add 1 to a fixed number: It refers to adding 1 to a fixed number continuously, such as adding 1 to 100 in a row, that is, adding 1 continuously, and adding to the end of the answer is 100. A fixed number is added to a fixed number, which is similar to a fixed number plus 1. 2. Constant addition and subtraction:

1 constant 37 plus or minus: 37 plus 3 times for a constant is 111, and 3 more times is 222....until the number of boards is 999 (27 times in total); Then subtract 37 from 999 in a row, minus 3 times to 888, minus 3 times to 777, and subtract 3 times to 666....Until it is finished.

2 constants 185 plus or minus: 185 constants plus 6 times is 1110, and 6 more times is 2220....until the number of disks is 9990; Then subtract 185 from 9990 until the reduction is exhausted.

3 constants 625 plus or minus: 625 plus 16 times for 10 000, 32 times for 20 000, 48 times for 30 000...., 62 500 for 100 times; Then subtract 625 from 62 500 until you finish it. 4 constants 16 835 even plus or minus:

The constant 16 835 is 50 505 for 3 times in a row, 101 101 for 6 times in a row, 151 515 for 9 times in a row...., add 60 times in a row to 1 010 100; Then subtract 16 835 from 1 010 100 until it is finished.

5 In addition to the addition and subtraction of the above constants, there are also some constants. For example: 16 875, three plates, seven plates, festival chart (dial in 32,260 738,125 to see a few plus a few, add and close four times to get 516,171,810,000, that is, Labor Day, Children's Day, the party's birthday, Army Day.

Wait a minute. Three, hit a hundred sons:

The so-called beating of 100 is the calculation of adding and subtracting these 100 numbers consecutively. It is calculated as 1+2+3+....+99+100, the result is 5 050; Then the side state slows down from 5 050 in 1-2-3....-100, the result of which is 0. Fourth, the basic skills training comparison table:

This equation has a certain formula, which is the addition of the equal difference series of the acorn mill.

The formula for the series of equal differences is the first term plus the last term multiplied by the number of terms divided by 2.

So this dish is entitled [(1+200)x 200] 2=20100.

So the answer to this question is 20100.

In the historical development and social life of mankind, mathematics plays an irreplaceable role, and it is also an indispensable basic tool for learning and researching modern science and technology. The name of abacus was first seen in the "Records of Mathematics" written by Xu Yue in the Han Dynasty. It is said that the abacus has a history of more than 1,800 years, and it should be calculated according to this point in time [4] .

However, the abacus operation algorithm at that time was still very different from today [4] . In Liang Dou's Song Dynasty's "Qingming Riverside Map", you can clearly see that there is an abacus on the counter of the "Zhao Taichengjia" pharmacy. The modern abacus blindness began between the Yuan and Ming dynasties.

Zhu Shijie's "Enlightenment of Arithmetic" in the Yuan Dynasty contains 36 mantras, which are roughly the same as today's [4] . During the Ming Dynasty, it was gradually introduced to Japan, Korea, Thailand and other places.

When I was a child, it only took a dozen seconds to add from 1 to 20 in junior high school, and now I can't even find the abacus, I just remember that adding to 6 equals 21, adding to 20 equals 210, and then adding up to practice very little.

Abacus 1 is added to 90 and so on at 4095.

90 = 91, Sakura 2 + 89 = 91, etc.

2. A total of 90 divided by 2=45 pairs, the ridge rise should be: 91x45=4095.

4095, with Gaussian algorithm: potato mess potato 1 + 90 = 91, 2 + 89 = 91, the number of a total of 90 2 = 45 pairs, it should be: 91 45 = 4095.

(1+100)·50=5050

This is a formula where the head item plus the tail item is multiplied (the number of items is divided by two).

1 + to 10 = 55, + to 20 = 210, + to 30 = 465, + to 40 = 820, + to 50 = 1275, + to 60 = 1830, + to 70 = 2485, + to 80 = 3240, + to 90 = 4105, + to 100 = 5060

The formula of mental arithmetic addition will do.

1 + to 10 = 55, + to 20 = 210, + to 30 = 465, + to 40 = 820, + to 50 = 1275, + to carry the sail 60 = 1830, + to hail 70 = 2485, + to 80 = 3240, + to 90 = 4105, + to 100 = 5060

51) There are a total of 50 sums of 101s, so the final result is 101 50 = 5050

Practice fingering, practice more.
