1. Eastern countries are afraid of numbers 4. His pronunciation is very close to the word "death". The Japanese, Koreans and Chinese equated it with the "unlucky" number. If you pay attention to the number of floors in buildings, you can see that the number "4" at the end of the floor is almost never recorded.

2. A small focus (explained simply by mathematics and logic). Take your year of birth, or rather the last 2 digits. Remember how old you were in 2011? To these years add the last digits from the year of birth. Bet you got 111?

3. If you square 111 111 111, the result will surprise! You will get 12345678987654321. These are all numbers in order. First increase, then go down.

4. Guess what happens when summing up all the numbers on the casino roulette? The number of the devil, whom many are afraid of, is 666.

5. Many people know about the various “6 of 49” lotteries (as it used to be in Sportloto). Do you know how many times the jackpot has been hit during the entire existence of the game? 3 times! The real lucky ones.

6. Everyone from school remembers the number Pi - 3.14. He even has 2 holidays. Unofficial of course. In America, this is March 14 (03.14) and July 22 (22/7). Ask why July? Because when dividing the number by the number of the month, it will turn out just the Pi number. Funny invented.

7. The largest number has 600 zeros per unit. He has his own name. It is a centillon.

8. Interesting facts about numbers and numbers also apply to scientists. An American graduate student in mathematics was once late for class. Equations were written on the board. George Danzig (that was the name of the graduate student) decided that this was asked at home. Tormented for several days, racking his brain, how did such a difficult task given, George decided. What was his surprise when he found out that this is an “unsolvable” problem in statistics. Many scientists have been straining their gyrus for years to solve the mystery of these problems.

9. Guess what is the most common female name? Anna. 100 million women are named by him.

10. Famous people also with their "cockroaches" in their heads and fears. For example, Sigmund Freud was panicky afraid of the number 62. This came to the point that Freud did not stay in hotels with more than 61 rooms. What if he, lucky, will get 62 of them all? And composer Schoenberg Arnold was afraid of a damn dozen. And he died on Friday 13 at the age of 76 (do you know how much 7 + 6 will turn out?). here it is - the magic of numbers. And he only says that thoughts are material. And there is no need to create fears for yourself so that they do not “finish off” you.

11. Another interesting fact about the diabolical number. Imagine that in the USSR architects wanted to create a neighborhood by building houses in it in such a way that the name of a great power could be read from outer space. However, the idea somehow fell apart or finances did not allow. But as a result, there is the 522nd microdistrict in Kharkov, where there are only 3 houses. And their satellite on the map shows as "666."

12. In the Himalayas there is a sacred mountain with a height of 6666 m. Its name is Kailash. Amazingly, its height is the distance to the center of the North Pole and at the same time to Stonehenge. Some kind of mysticism. But the mountain is actually very beautiful.

13. The centipede actually has far from 40 legs. People often call it a spider with long and thin "legs." She moves so fast that she seems 40 feet. However, some call centipedes centipedes, in which in fact the number of legs reaches 400, and sometimes even higher. Those who count 100 legs should be wary of this insect. It bites painfully. But the so-called millipedes are generally harmless and harmless. Biology is an interesting science.

14. In Budapest, trolleybuses received numbers in the year 49. It was in that year that Stalin celebrated his anniversary - the seventh dozen. And the very first trolleybus was assigned number 70 (although now there is no such route anymore). Since then, numbers were given to routes after 70. There is neither the first, nor the twentieth, nor the fifty-third.

15. Is it realistic to live a million days? Interesting. But if you count, then it is 27 centuries. So many days have not passed since the beginning of our era. So the answer is unequivocal - no, you can not live so many days for 1 person.

• Why in a circle of 360 degrees

The history of the development of mankind knew different number systems. In ancient Babylon, invented the six-decimal number system. The Babylonians were considered triples, according to the number of joints on each finger of the left hand, that is, up to 12. Then each finger of the right hand meant 12. Thanks to this, the score lasted up to 60. The number 60 became ritual in Ancient Babylon: there were so many gods, each of them had its numerical designation from 1 to 60. For example, the creator of the universe, was designated by the number 20; planet god Jupiter - 11; the god of the moon - 30. The height of the golden idol installed in the temple of Nebuchadnezzar was 60 cubits. It is not surprising that the number 60 formed the basis of the ancient Babylonian calendar. Observing the peculiarities of the circular motion of the Moon and the Sun, the Babylonians came to the conclusion that the year consists of 360 days. Therefore, they divided the circle into 360 degrees, one degree for each day. The year was divided into 12 months, because the sun lingers in each constellation of the zodiac for about a month, and the moon moves through the sky in a month - 30 days. In one of the Babylonian temples there was a statue of God, surrounded by 360 jugs, each of which symbolized one of the days of the year. CHILDREN X IDm2012 062  22:01, November 7, 2012 (MSK)

• From the story of scratch.

The word "zero" comes from the Latin word "Nulla", meaning "no" (significant digit). Greek astronomers who used hexadecimal fractions introduced a special sign in the form of the letter O (omicron, the first letter in the Greek word "onden" meaning "nothing") to separate the digits. In the VII century. in ancient India, the decimal positional number system was already used, and along with it, zero was systematically applied, which was denoted by a dot, as well as a circle. Some scholars believe that the circle for zero introduced by the Greeks. Indians called zero Sunya, meaning empty, in the sense of no discharge in number. The Arabs, from whom the Europeans adopted the decimal number system, translated the Indian "sunya" with the Arabic word "as-sifr". That is why until the XVII century. zero was called a "digit". For Europeans, Indian arithmetic and, in particular, zero were initially considered some kind of secret. Therefore, they began to give the name "numbers" or "code" of any cryptography. At present, zero is not just a sign for decoupling, but a number that can be added. subtract, multiply and divide, like other numbers. The only restriction is that you cannot divide by zero.

• About pi

It is known that the ratio of the circumference to the diameter cannot be accurately expressed either by an integer, by an ordinary fraction, or by a final fraction. The values \u200b\u200bfor pi, which are close to the deficiency and excess, were obtained by Archimedes by considering the polygons inscribed in the circle and described around it with a sufficiently large number of sides. In some Asian countries, the value pi \u003d root (10) occurs, i.e. 3,162 .... Astronomer Wang Fan (229-267) argued that pi \u003d 142/45, i.e. 3,155 ..., and Zu Chun-chi (428-499) spoke of the "inaccurate" value 22/7 and the "exact" value 355/113, showing that pi is between 3.1415926 and 3.1415927. The last value was recorded in the VII century. in the form of a named number: 3 zhang 1 chi 4 tsun 1 fen 5 li 9 hao 2 miao 7 ho. By 1963, 100,265 decimal digits of the number pi were found using electronic machines. The calculation of such a large number of signs for pi does not have practical value, but shows only the huge advantage and perfection of modern means and methods of calculation in comparison with the old ones.

Facts About Negative Numbers

In our time, negative numbers are known to many, but this was not always the case. For the first time, negative numbers began to be used in China in the III century, but it was allowed to use them only in exceptional cases, since they were considered nonsense. A little later, negative numbers began to be used in India to denote debts.

So, in the work "Mathematics" in nine books, published in 179 AD e., during the Han Dynasty and commented in 263 by Liu Hui, in the Chinese system of counting sticks, black sticks were used for negative numbers, and red ones for positive numbers. Also, to indicate negative numbers, Liu Hui used inclined counting sticks.

The “-” sign, which is now used to denote negative numbers, was first noticed in the ancient Bakhshali manuscript in India, but there is no consensus among scholars as to when it was drawn up, the range of disagreement is from 200 to 600 AD. e.

Negative numbers were already known in India in 630 AD. e .. They were used by the mathematician Brahmagupta (598-668 years).

For the first time in Europe, negative numbers began to be used around 275 AD. e .. They were introduced into use by the Greek mathematician Diophantus of Alexandria, but in the West they were considered absurd until the appearance of the book Ars Magna (Great Art), written in 1545 by the Italian mathematician Girolamo Cardano (1501-1576).

Prime Facts

Numbers 2 and 5 are the only ones in a series of primes that end in 2 and 5.

Other Facts About Numbers

We all know that there are words palindromes. That is, those that can be read from left to right and from right to left and their value does not change. However, there are palindrome numbers (palindromones). They are mirror numbers that will be read and have the same value in both directions, for example, 1234321.

The word Googol (origin of the Google brand) denotes the number 1 with 100 zeros.

The only number that cannot be written in Roman numerals is "Zero". Also, in modern mathematics, zero has some features of its interpretation. So, in Russian mathematics it is not considered a number of natural numbers, and foreign science classifies it.

We all know the numbers from 0 to 9. But how did they appear? Where did these familiar 0, 1, 2, 3, 4, 5, 6, 7, 8 and 9 come from, which we constantly use in everyday life? What are they called and why do they have such a name? We will plunge into history and find out the answers to these and many other questions.

History of numbers

Even in ancient times, a person needed an account. Even when there were still no letters and numbers, when an ancient person did not know what two or five were, he needed to perform simple steps to divide the prey, determine the number of people to hunt, and many others.

Initially, he used his own hands, and sometimes even his feet, and showed on his fingers. Remember the saying "I know how my 5 fingers"? It is possible that it was invented in those distant times. Fingers were the first tools for counting.

Life flowed on its own, everything changed, people needed some more signs except fingers. The numbers became more and more, it was difficult to keep them in the head, it was necessary to somehow designate and write them down. So the numbers appeared. Moreover, different countries came up with their own. The first were the Egyptians, then the Greeks and Romans. Now we sometimes use Roman numerals. However, the most popular and used by us to this day are the numbers invented in India even before the beginning of the V century.

Why are they called that?

Why are the usual numbers called Arabic, because they were invented in India? And all because they gained distribution precisely thanks to the Arab countries, which began to actively use them. The Arabs took Indian numbers, changed them a bit and began to actively use them. Among those who helped the world discover Arabic numbers that were familiar to us were the Frenchman Alexander de Villier, the British teacher John Halifax, and the famous mathematician Fibonacci, who often traveled to the East and studied the works of Arab scholars.

The word "figure" is of Arab origin. The consonant Arabic word "cipher" means those icons that we used to use 0,1, 2 ... 9.

Get to know the numbers closer

Number 1

Guess the riddle:

Sly Nose Sister
  The account will open ... ( unit)

That's right, this is the number 1. The very first digit. It is easy to write. It is with her that the acquaintance with numbers always begins. Units can be any number, for example 1 + 1 \u003d 2, etc. In China, a unit is the beginning of everything. However, with us as well.

And also integrity. Millions of creation without a pair are not a whole ... For example, two wings, two eyes, two ears and other parts of the body. Any family begins with two ...

Often the number two is found in the literature. Remember Krylov’s fables “Two Pigeons”, “Two Dogs” or the fairy tale of the Brothers Grimm “Two Brothers”, the tale of Nosov “Two Frosts”. Two is the smallest prime. And also the worst grade in school. In order not to get deuces, you need to study hard.

Number 3

Let us guess another riddle:

What a miracle
  What a figure!
  Every tomboy knows.
  Even in our alphabet
  She has a twin sister ... ( three)

The figure really looks like the letters of the Russian alphabet "Z".

Number 4

I’m standing after number 3,
And the figure five is slightly inferior.
  What kind of figure am I?

Digit 4. They say that the four are the most magical of the numbers. In most states, it is a symbol of integrity. But in Asian countries they treat her with concern. In life, we meet the number 4 very often: 4 seasons, 4 cardinal points, 4 natural elements, 4 times of day, etc.

Number 5

How many fingers on the hand
  And a penny in a patch
  The starfish of the rays
  Beaks in five rooks,
  Maple Leaf Blades
  And the corners of the bastion,

Figure 5. In most schools - this is the best mark! Although, for example, in Germany, the top five are put on the contrary to those who try poorly. Where can we meet the top five? For example, on Earth there are 5 continents, and the Olympic symbol has 5 rings, and 5 fingers on the arms and legs.

Number 6

How many letters does the dragon have
  And a million zeros
  Different chess pieces,
  The wings of three white hens,
  May Beetle Feet
  And the sides of the chest.

How many colors are there in a bright rainbow?
  How many wonders of the world are there on earth?
