How Synterra Media left Rostelecom
The TelecomCenter company also joined Synterra, which was renamed to SynterraMedia. IN 2010 r. Synterra was sold to mobile operator Megafon, which before 2008 r. was under the control of the "St. Petersburg group of communications". The transaction amount was $298 million, of which $100 million were to be paid as deferred payment.
Prior to that, Synterra Cyprus became the owner of another asset of the "St. Petersburg group of communications" – "Interregional Transittelecom" (MTT). In the 1990s, MTT was the exclusive provider of longdistance services for cellular operators. Since the mid2000s, MTT also began to provide longdistance communication services for fixed telephony subscribers.. The company also launched a number of other communication services, including OTT services.
IN 2013 r. MTT was merged with the fixedline operator StartTelecom (also belonged to the "St. Petersburg group of communications" in the "MTTGroup". This company belongs to the Alternativa Capital fund, created by Leonid Reiman (at that time, Reiman left the civil service and went into business).

The meaning of the number
Pronunciation of larger numbers is often different..
10 100  Google (the number was invented by the 9yearold nephew of the American mathematician E.. Kasner)
 10 123  quadragintillion
 10 153  quinquagintillion
 10 183  sexagintillion
 10 213  Septuagintillion
 10 243  octogintillion
 10 273  nonagintillion
 10 303  centillion
The names of even larger numbers are obtained by direct or reverse order of Latin numerals (correct are not known for certain):
 10 306  antcentillion or centunillion
 10 309  duocentillion or centduollion
 10 312  trecentillion or centtrillion
 10 315  quattorcentillion or centquadrillion
 10 402  tretrigintacentillion or centtretrigintillion
The second option is more consistent with the construction of numbers in Latin, and in this case, ambiguities do not arise (eg, the number of trecentillion by the first spelling is and 10 903 and 10 312 ), therefore we consider the second option more correct. Next numbers:
 10 603  ducentillion

There are a few simple rules to learn, which regulate the spelling of numeral names.
1. The numbers "FIVE"  "NINETEEN", as well as "TWENTY" and "THIRTY" b is written at the end, and the numerals "FIFTY"  "EIGHTY" and "FIVE HUNDRED"  "NINE HUNDRED"  in the middle of the word.
2. The numerals "NINE" and "STO" have the ending O in the nominative and accusative cases, and in other cases  ending A. (SPEND ONE HUNDRED RUBLES, DOES NOT ENOUGH HUNDRED RUBLES). The numeral "FORTY" in the nominative and accusative cases has a zero ending, and in other cases  ending A. ( He's not even forty years old). In the nominative and accusative cases, the numeral "DVESTI" has the ending AND, and the numerals "THREE" and "FOUR RAYS"  ending A. (THERE IS ALREADY THREE HUNDRED YEARS).
3. Compound numbers (and quantitative, and ordinal), two pillars, are written together (SIXTEEN, SIXTEENTH, NINE HUNDRED, NINE HUNDRED).
4. Compound numbers are written separately, having so many words, how many significant digits, apart from zeros (FIVE HUNDRED TWENTY THREE. FIVE HUNDRED TWENTYTHIRD). However, ordinal numbers, ending in THEW, MILLIONTH, BILLION are spelled together (HUNDRED, TWO HUNDRED THIRTYFIVE MILLION).
5. Fractional numbers are written separately (THREEFIFTHS, THREE WHOLE AND ONE SECOND), but the numbers are TWO HALF, THREEHALF, FOURHALF are written together. The numerals PALTOURA and POLTOORASTA have only two case forms: One and a half (HALF IN W. R.), HALFHALF for the nominative and accusative and HALF, HALF HALF for all other cases without generic differences.
6. All the words forming them are inclined in compound cardinal numbers (TWO FIFTY SIX  TWO HUNDRED FIFTY SIX, TWO FIFTY SIX), When declension of fractional numbers, both parts also change (THREE FIFTH  THREE FIFTH  THREE FIFTH  THREE FIFTH  ABOUT THREE FIFTH).

According to the database "Kontur.Fokus", in 2019 r. the company's revenue was 800 RUB million, shrinking compared to 2018 r. more than doubled. The company's net profit amounted to 240 RUB million, EBITDA (profit before taxes, interest on loans and amortization expenses) – 320 RUB million.
Rostelecom acquired the transferring company Synterra Media from MTT Group
Rostelecom believes, that the acquisition of Synterra Media will strengthen the operator's competitive position in the segment of professional ground delivery of video content. Rostelecom has historically been a player in the TV content delivery market, and the competence center for working with the media market created on the basis of Synterra Medi will allow the company to become a “onestop shop” for receiving a range of technological services from Rostelecom, – said Vice President of Rostelecom for corporate and government segments Valery Ermakov.
Synterra Media was originally called Telecom Center and was founded in 1994 g., and the founder of the company was Rostelecom. IN 2005 r.

How does the "Amount in words online" calculator work?
Enter the numerical variant of the amount in rubles in the calculator field. The program will react to the number input automatically and suggest a verbal formulation of the amount. It will be written below the numeric field immediately after entering the numbers. You don't need to press anything additionally.
The capital decoding appears exactly in that variant, which is accepted for financial documents: rubles are indicated in words, pennies  in numbers, this rule is. The amount is capitalized, the value of the amount in rubles and kopecks is not separated by a comma or other punctuation mark (point, bracket). for example: “Twenty thousand five hundred and one ruble 51 penny ".
If you need to indicate the number of kopecks in the amount, write them after a comma or a point in the number. Space cannot be used for this purpose.. for example: "20500.56" or "346.5".
If the amount is whole, no kopecks, write a number without comma and zero indicators after it. for example: “3000000”. The calculator will understand everything by itself and offer a capital version of the amount with the addition: "00 kopecks". But the indication of the sum in the form of a decimal fraction with zero values after the decimal point is also acceptable.. for example: “100,00”. Third decimal place (points) cannot be delivered.
be careful, prescribing large numbers, especially with multiple zeros in a row.

A billion is how much?
A billion is a thousand million, or a million thousand. A billion is written as one followed by nine zeros.
This is a very large number., and it's hard to imagine. for example, a billion seconds won't run in a whole year, and even for 10 years will not run, and even for 30. A billion seconds is almost 32 of the year. You can reach the moon in a billion steps. And to gather a company of a billion people you will need 7 countries like Russia.
Billion is the exclusive name for a large number. All other large numbers end in on: million, trillion, quadrillion, quintillion. A thousand million would be worth calling a billion, but somehow the word billion did not take root in the Russian language, instead of a billion they say “billion”.
Do you know, as a number with a hundred zeros is called? Google.
A billion seconds is not 32 but almost 33 of the year , something around 32 years 9 or 10 months.
How many thousands in a billion?
A billion is 1 000 000 000.
We need to know how many times to take 1000, to get it 1 000 000 000.
1 000 000 000/1000 = 1 000 000

There is no specific answer to this question..
According to Forbes statistics, the richest is Amazon founder Jeff Bezos. But, you can argue and argue as much as you like, that entrepreneurs are the richest people, everyone is either afraid to mention this guy, either ignore.
Vladimir Putin during the 2013 by 2016 year was recognized as the most influential person in the world. Kremlin reports, what Putin has (official) the annual salary is only 8,0 million. rubles, but in fact, his income exceeds the wildest expectations.
The reason, for which he is so rich, is that, that he owns most of almost all Russian companies, and also has access to government assets and, in fact, all, what belongs to Russia is owned by Putin.
Although I have no proof, but somewhere it was reported, what is his capital 200 billion dollars, what makes him richer, than officially the richest man and Amazon CEO Jeff Bezos (113 billion dollars, the maximum was 160 billion).

What is the pattern in the naming of large numbers?
There are two systems for naming numbers: long scale and short scale(used by us). It's simple on a short scale: number 1000 ^ x is formed from the name of the number x1: 1000^(1+1)  million, 1000^(1+2)  Billion(more often we have a billion)  from "bi"  two, 1000^(1+3)  trillion  from "three", 1000^(1+4)  quadrillion  from “quadro”  four, etc.
On a long scale, numbers are formed from the power of a million:
1000000^ 1.0  million; 1000000^ 1.5  billion  thousand million; 1000000^ 2.0  billion  from "bi"  two; 1000000^ 2.5  billiards  a thousand billions; 1000000^ 3.0  trillion  from "three"; 1000000^ 3.5  trillion  thousand trillion; 1000000^ 4.0  quadrillion  "quad"  four; 1000000^ 4.5  quadrillion  thousand quadrillion; etc.

Spelling of numeral names
CARDINAL NUMBERS
1. For numbers from five to twenty and the number thirty, the letter ь is written at the end, and for numerals five ten  eight ten , five hundred  nine hundred  in the middle of the word, ie. between two roots.
2. The numeral one declines the same, as an adjective in the singular:
 numerals have two, three, four  special case endings:
 numerals five, six, seven, eight, nine, ten and the numbers atten are inclined the same, as nouns of the third declension:
3. The numerals ninety and one hundred end in o in the nominative and accusative, in other case forms  ending а : get ninety (the table) rubles, subtract from ninety a (what) rubles, stay from ninety (what) rubles .
The numeral forty in the nominative and accusative cases has a zero ending, and in other case forms  the ending а : forty rubles are missing, add to forty rubles .
4. Numeral two has an ending in both the nominative and accusative cases , and three hundred a and four hundred a  ending a. Numbers have two hundred, three hundred, four hundred and one hundred incline both parts:
5. Compound numbers, two or more words, written separately: six hundred eighty four, one thousand nine hundred ninety one, three thousand eight . In quantitative compound numbers, each word is declined:
five hundred ninetysix
about five hundred ninety six
ORDINALS
1. Compound ordinal numbers as derivatives of cardinal numbers are written together, and the composite separately: sixteenth, seventieth, nine hundredth; one thousand nine hundred ninety first, three thousand eighth.
2. Ordinals, ending in thousandth, millionth, billionth, are written together: one hundred and thirty thousandth (one hundred thirty thousand), fiftyfour million (fifty four million), two hundred and thirty billion (two hundred thirty billion).
3. The continuous spelling of such designations is explained by the fact, that words with quantitative meaning: one thousand, million, billion  have signs of nouns (have genus, two forms of number  singular and plural, combined with numerals), and consequently, are formed as a complex adjective, arising from a combination of a numeral with a noun (the components of the combination are linked by the way of subordination). This way of education is also evidenced by the wordforming suffix н, characteristic of adjectives; compare: triple (three buckets)  one hundred and thirty thousandth (one hundred thirty thousand).
