In a similar vein to why the Roman numbering system did not readily go above 3,999, the number zero was not featured by the Romans simply because they had little use for it! The widespread adoption of the Hindu-Arabic system was also facilitated by the development of printing technology in the 15th century AD. By the 11th century, Arabic numerals had been introduced into Europe from al-Andalus, by way of Arab traders and arithmetic treatises. Roman numerals, however, proved very persistent, remaining in common use in the West well into the 14th and 15th centuries, even in accounting and other business records (where the actual calculations would have been made using an abacus). Replacement by their more convenient "Arabic" equivalents was quite gradual, and Roman numerals are still used today in certain contexts. A few examples of their current use are: Capital or small capital Roman numerals are widely used in Romance languages to denote centuries, e.g. the French XVIII e siècle [71] and the Spanish siglo XVIII (not XVIII siglo) for "18th century". Slavic and Turkic languages in and adjacent to Russia similarly favor Roman numerals (e.g. Russian xviii век, Azeri xviii əsr). On the other hand, in Turkish and Slavic languages in Central Europe, like most Germanic languages, one writes "18." (with a period) before the local word for "century" (e.g. Turkish 18. yüzyıl, Czech 18. století). In education, school grades (in the sense of year-groups rather than test scores) are sometimes referred to by a Roman numeral; for example, "grade IX" is sometimes seen for "grade 9".

The system uses a combination of letters from the Latin alphabet to represent numbers. The basic symbols are I, V, X, L, C, D, and M, which represent 1, 5, 10, 50, 100, 500, and 1,000, respectively.One of the most similar numbering systems to that used by the Romans was in use by the Etruscans. This will come as no surprise, as the Etruscan civilization covered much of northern Italy, and had a significant impact upon the development of the Romans to the south. Excerpt from Bibliothèque nationale de France. [36] The Roman numeral for 500 is rendered as C V, instead of D. While subtractive notation for 4, 40 and 400 ( IV, XL and CD) has been the usual form since Roman times, additive notation to represent these numbers ( IIII, XXXX and CCCC) [9] continued to be used, including in compound numbers like 24 ( XXIIII), [10] 74 ( LXXIIII), [11] and 490 ( CCCCLXXXX). [12] The additive forms for 9, 90, and 900 ( VIIII, [9] LXXXX, [13] and DCCCC [14]) have also been used, although less often. A superscript "o" (sometimes written directly above the symbol) was sometimes used as an ordinal indicator. [64] Number Literature and Legal Documents: Ancient Roman scripts, legal decrees, and treaties frequently used Roman numerals for dates and other numerical references. This practice underscored the standardized system of record-keeping and documentation in the expansive Roman Empire.

Book VI: " tam vicinum Arsaniae fluere eum in regione Arrhene Claudius Caesar auctor est, ut, cum intumuere, confluant nec tamen misceantur leviorque Arsanias innatet MMMM ferme spatio, mox divisus in Euphraten mergatur." A notable exception to the use of Roman numerals in Europe is in Greece, where Greek numerals (based on the Greek alphabet) are generally used in contexts where Roman numerals would be used elsewhere. If so, rather than Julius Caesar pondering to himself before a battle that he had an army of 24,000 men, he may have been more likely to just think that he had 6 legions.Mixed Roman and Arabic numerals are sometimes used in numeric representations of dates (especially in formal letters and official documents, but also on tombstones). The month is written in Roman numerals, while the day is in Arabic numerals: "4. VI.1789" and " VI.4.1789" both refer unambiguously to 4 June 1789. There are also historical examples of other additive and multiplicative forms, and forms which seem to reflect spoken phrases. Some of these variants may have been regarded as errors even by contemporaries. Using the vinculum, conventional Roman numerals are multiplied by 1,000 by adding a "bar" or "overline", thus: [49] Archived copy". Archived from the original on 4 March 2016 . Retrieved 25 January 2014. {{ cite web}}: CS1 maint: archived copy as title ( link) One justification for the existence of pre-combined numbers is to facilitate the setting of multiple-letter numbers (such as VIII) on a single horizontal line in Asian vertical text. The Unicode standard, however, includes special Roman numeral code points for compatibility only, stating that "[f]or most purposes, it is preferable to compose the Roman numerals from sequences of the appropriate Latin letters". [76]

Lower-case instances of Roman numerals began to appear, and it became common for a "j" to be used instead of a final "i" (a lowercase I or 1). This typographical flourish was not only an example of the neat, cursive-style writing that typifies Medieval and later documents, but it also had a practical use. Individual strings of stringed instruments, such as the violin, are often denoted by Roman numerals, with higher numbers denoting lower strings. The highest number that can be expressed in pure Roman numeral form is 3,999 which is written as MMMCMXCIX. The number zero does not have its own Roman numeral. At about 725, Bede or one of his colleagues used the letter N, the abbreviation (short form) of nihil (the Latin word for " nothing"). [3] Fractions [ change | change source ] A semis ( S) coin.One possible explanation for this is because humans started counting using fingers (See "Origin of Roman Numerals" section below for more). The Romans used a duodecimal rather than a decimal system for fractions, as the divisibility of twelve (12 = 2 2 × 3) makes it easier to handle the common fractions of 1⁄ 3 and 1⁄ 4 than does a system based on ten (10 = 2 × 5). Notation for fractions other than 1⁄ 2 is mainly found on surviving Roman coins, many of which had values that were duodecimal fractions of the unit as. Fractions less than 1⁄ 2 are indicated by a dot ( ·) for each uncia "twelfth", the source of the English words inch and ounce; dots are repeated for fractions up to five twelfths. Six twelfths (one half), is S for semis "half". Uncia dots were added to S for fractions from seven to eleven twelfths, just as tallies were added to V for whole numbers from six to nine. [46] The arrangement of the dots was variable and not necessarily linear. Five dots arranged like ( ⁙) (as on the face of a die) are known as a quincunx, from the name of the Roman fraction/coin. The Latin words sextans and quadrans are the source of the English words sextant and quadrant. Another limitation of the Roman numeral system is that it is not a positional system, meaning that the position of a symbol in a number does not determine its value. Instead, the value of a symbol depends on its form and the symbols that come before and after it. Comparing the Roman numeral system with other number systems can help us understand its unique features and limitations, and why the numbering system of the ancient Romans was gradually replaced, albeit many centuries after the fall of the Roman empire.

The history of Roman numerals and Roman mathematics isn't well documented. As humans likely began counting by using the simplest things available - the fingers - mathematics developed in a base unit of 10.Chronograms, messages with dates encoded into them, were popular during the Renaissance era. The chronogram would be a phrase containing the letters I, V, X, L, C, D, and M. By putting these letters together, the reader would obtain a number, usually indicating a particular year.
