This article lists and discusses the usage and derivation of names of large numberstogether with their possible extensions. The following table lists those names of large numbers that are found in many English dictionaries and thus have a claim to being "real words. Indian Sextillion does not use millions, but has its own system of large numbers including lakhs and crores. English also has many words, such as "zillion", used informally to mean large but unspecified amounts; see indefinite and fictitious numbers.

Apart from millionthe words in this list ending with - illion are all derived by adding prefixes bi - tri - etc. Trigintillionoften cited as a word in discussions of names of large numbers, is not included in any of them, nor are any of the names that sextilliom easily be created by extending the naming pattern unvigintillionduovigintillionduoquinquagintillionetc. All of the dictionaries included googol and googolplexgenerally crediting it to the Kasner and Newman book and to Kasner's nephew.

None include any higher names in the googol family googolduplex, etc. The Oxford English Dictionary comments that googol and googolplex are "not in formal mathematical use". Some names of large numbers, such as millionbillionand trillionhave real referents in human experience, and are encountered in many contexts.

At times, the names of large numbers have been forced into common usage as a result of hyperinflation. Names of larger numbers, however, have a tenuous, artificial existence, rarely found outside definitions, lists, and discussions of the ways in which large numbers are named. Even well-established names sexitllion sextillion are rarely used, since in the context of science, including astronomy, where such large numbers often occur, they are nearly always written using scientific notation.

In this notation, powers of ten are expressed as 10 with a numeric superscript, sextillion. This is easier to say and less ambiguous than "quattuordecillion", which means something different in sxtillion long scale and the short scale.

When a number represents a quantity rather than a count, SI prefixes can be used—thus "femtosecond", not sextillio quadrillionth of a second"—although often powers of ten are used instead of some of the very high and very low prefixes. In some cases, specialized units are used, sextillion as the astronomer's parsec and light year or the particle physicist's barn.

Nevertheless, large numbers have an intellectual fascination and are of mathematical interest, and giving them names is one of the ways in which people try to conceptualize and understand them. One of the earliest examples of this is The Sand Reckonerin which Archimedes gave a system for naming large numbers. To do this, he called the numbers up to a myriad myriad 10 8 "first numbers" and called 10 8 itself the "unit of the second numbers".

This became the "unit of the third numbers", whose multiples were the third numbers, and so on. Archimedes continued naming numbers in this way up to a myriad myriad times the unit of the 10 8 -th numbers, i.

Since then, many others have engaged in the pursuit of conceptualizing and naming numbers that really have no existence outside sextillio imagination. One motivation for such a pursuit is that attributed to the inventor of the word googolwho was certain that any finite number "had to have a name".

Another possible motivation is competition between students in computer programming courses, where a common exercise is that of writing a program to output numbers in the form of English words. Most names proposed for large numbers belong to systematic schemes which are extensible. Thus, many names for large numbers are simply zextillion result of following a naming system to its logical conclusion—or extending it further.

Subsequently, Nicolas Chuquet wrote a book Triparty en la science des nombres which was not published during Chuquet's lifetime. However, most of it was copied by Estienne de La Roche for a portion of his book, L'arismetique. Chuquet's book contains a passage in which he shows a large number marked off into groups of six digits, with the comment:.

Ou qui sexyillion le premier point peult signiffier million Le second point byllion Le tiers point tryllion Le quart quadrillion Le cinq sextillion quyllion Le six e sixlion Le sept. Or if you prefer the first mark can signify million, the second mark byllion, the third mark tryllion, the fourth quadrillion, the fifth quyillion, the sixth sixlion, the seventh septyllion, the eighth ottyllion, the ninth nonyllion and so on with others as far as you wish to go.

Adam and Chuquet seztillion the long scale of powers of a million; that is, Adam's bymillion Chuquet's byllion denoted 10 12and Adam's trimillion Chuquet's tryllion denoted 10 The names googol and googolplex were invented by Edward Kasner 's nephew Milton Sirotta and introduced in Kasner and Newman's book Mathematics and the Imagination [13] in the following passage:.

The name "googol" was invented by a child Dr. Kasner's nine-year-old nephew who was asked to think up a name for a very big number, namely 1 with one hundred zeroes after sextillion. He was very certain that this number was not infinite, and therefore equally certain that it had to have a name. At the same time that he suggested "googol" he gave a name for a still larger number: "Googolplex".

A googolplex is much larger than a googol, but is still finite, as the inventor sextillion the name was quick to sextilliob out. It was first suggested that a googolplex should be 1, followed by writing zeros until you got tired.

This is a description of what would actually happen if one actually tried to write a googolplex, but different people get tired at different times and it would never do to have Carnera a better mathematician than Dr. Einsteinsimply because he had more endurance. The googolplex is, then, a specific finite number, equal to 1 with sextil,ion googol zeros after it. Conway and Guy [14] have suggested that N-plex be used as a name for 10 N. This number ten to the power of a googolplex is also known as a googolduplex and googolplexian.

None of these names are in wide use, nor are any currently found in dictionaries. The names googol and googolplex inspired the name of the Internet company Google and its corporate headquartersthe Googleplexrespectively. This section illustrates several systems for naming large numbers, and shows how they can be extended past vigintillion.

It was adapted from French usage, and is similar to the system that was documented or invented by Chuquet. Traditional American usage which was also adapted from French usage but at a later dateCanadian, and modern British usage assign new names for sextiillion power of one thousand the short scale.

Due to its dominance in the financial world sextilliln by the US dollarthis was adopted for sextillion United Nations documents. Traditional French usage has varied; inFrance, which had been using the short scale, reverted to the long scale.

The term milliard is unambiguous eextillion always means 10 9. It is almost never seen in American usage and rarely in British usage, but frequently in continental European usage.

The term is sometimes attributed to French mathematician Jacques Peletier du Mans circa for this reason, the long scale is also known as sexrillion Chuquet-Peletier systembut the Oxford English Dictionary states that the term derives from post-Classical Latin term milliartumwhich became milliare and then milliart and finally our modern term.

For additional details, see billion and long and short scales. The choice of roots and the concatenation procedure is that of the standard dictionary numbers if n is 20 or smaller. For larger n between 21 andprefixes can be constructed based on a system described by John Horton Conway and Richard K. Guy : [14]. Since the system of using Latin prefixes will become ambiguous for numbers with exponents of a size which the Romans rarely counted to, like 10 6,Conway and Guy have also proposed a consistent set of conventions which permit, in principle, the extension of this sedtillion to provide English names for any integer whatsoever.

The following table shows number names generated by the system described by Conway and Guy for the short and long scales. Names of reciprocals of large numbers are not listed, as they are regularly formed by adding -th, e. The International System of Quantities ISQ defines a series of prefixes denoting integer powers of between 1 and 8.

If you have ever wondered what number comes after a trillion , read on. For example, do you know how many zeros there are in a vigintillion? Someday you may need to know this for science or math class. Then again, you might just want to impress a friend or teacher. It helps track these multiples of 10 because the larger the number is, the more zeroes are needed.

In the below table, the first column lists the name of the number, the second provides the number of zeros that follow the initial digit, while the third tells you how many groups of three zeros you would need to write out each number. A table, as the one above, can certainly be helpful in listing the names of all of the subsequent numbers depending on how many zeros they have.

But it can be really mind-boggling to see just what some of those numbers look like. Below is a listing, including all of the zeros, for the numbers up to decillion. For comparison, that's a little more than half the numbers listed in the above table. Ten: 10 1 zero Hundred: 2 zeros Thousand: 3 zeros Ten thousand 10, 4 zeros Hundred thousand , 5 zeros Million 1,, 6 zeros Billion 1,,, 9 zeros Trillion 1,,,, 12 zeros Quadrillion 1,,,,, 15 zeros Quintillion 1,,,,,, 18 zeros Sextillion 1,,,,,,, 21 zeros Septillion 1,,,,,,,, 24 zeros Octillion 1,,,,,,,,, 27 zeros Nonillion 1,,,,,,,,,, 30 zeros Decillion 1,,,,,,,,,,, 33 zeros.
