The widespread adoption of the Hindu-Arabic system was also facilitated by the development of printing technology in the 15th century AD. This may work neatly, however there is much debate over whether this system was in fact actually used by the ancient Romans, or whether it was simply a product of later generations and civilizations. 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.

Each Latin letter that was part of the Roman numerals of the past were a representation of a base. These numbers were generally four-digit. The Roman numeral system may also be used to signify positive integers, by adding values. Book II, Section 8: " ... ab utroque latere eius collis transversam fossam obduxit circiter passuum CCCC et ad extremas fossas castella constituit..." Roman numerals originate, as the name suggests, from the Ancient Roman empire. Unlike our position based system with base 10, the roman system is based on addition (and sometimes subtraction) of seven different values. These are symbols used to represent these values:

Talking of Roman numerals in movies and TV shows, if you want to find out when that movie or show you just watched was made, you can work it out yourself using the explanation above… or just use the handy list below which show dates from the year 1990 onwards! 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". Tentzel, Wilhelm Ernst (1700). Saxonia Nvmismatica: Das ist: Die Historie Des Durchlauchtigsten... (in German). p.26. Another factor that contributed to the rise of the Hindu-Arabic system was the growing influence of Islamic scholarship in the Middle Ages.

In mathematics (including trigonometry, statistics, and calculus), when a graph includes negative numbers, its quadrants are named using I, II, III, and IV. These quadrant names signify positive numbers on both axes, negative numbers on the X axis, negative numbers on both axes, and negative numbers on the Y axis, respectively. The use of Roman numerals to designate quadrants avoids confusion, since Arabic numerals are used for the actual data represented in the graph. With only a limited number of letters, and with numbers being based around a unit of 10, there are in fact only six instances where this can happen: There are some examples of year numbers after 1000 written as two Roman numerals 1–99, e.g. 1613 as XVIXIII, corresponding to the common reading "sixteen thirteen" of such year numbers in English, or 1519 as X C VXIX as in French quinze-cent-dix-neuf (fifteen-hundred and nineteen), and similar readings in other languages. [37] It was a common alternative to the apostrophic ↀ during the Imperial era around the Roman world (M for '1000' was not in use until the Medieval period). [50] [51] It continued in use in the Middle Ages, though it became known more commonly as titulus, [52] and it appears in modern editions of classical and medieval Latin texts. [53] [54] While it may have been less common to deal with numbers of 4,000 and above, or have the need to write it down, it still seems unlikely that the Romans would not deal with some things over this amount.

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. Roman Numerals Chart 1997–The entire world including the United States, uses the subtractive and additive system of numbering known as Roman Numerals. While the Babylonian numbers system was introduced in Egypt by the Egyptians. It wasn’t the same numbering system as is currently used by Roman numerals. Arabic numerals have taken the place of Roman numbers. Adkins, Lesley; Adkins, Roy A (2004). Handbook to life in ancient Rome (2ed.). Facts On File. p.270. ISBN 0-8160-5026-0.

Goines, David Lance. A Constructed Roman Alphabet: A Geometric Analysis of the Greek and Roman Capitals and of the Arabic Numerals. Boston: D.R. Godine, 1982. In theology and biblical scholarship, the Septuagint is often referred to as LXX, as this translation of the Old Testament into Greek is named for the legendary number of its translators ( septuaginta being Latin for "seventy"). 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.

This handy list of Roman numerals provides the most common numbers and useful points of reference. Looking at the chart, certain numbers are straightforward. The letters themselves correspond to the number they represent (e.g. I = 1, V = 5 etc).
