How Do Roman Numerals Work?

chart of Roman numerals

The cyphers I, V, X, L, C, D, and M, which stand for the numbers 1, 5, 10, 50, 100, 500, and 1,000, make up Roman numerals.

These characters’ amount and arrangement controlled the final number’s value. Hence the ancient Romans only used a combination of seven letters to write numerals!

Roman numerals may initially appear strange compared to how we currently express numbers (which are based on early Arabic numerals). This might will explain the fact that humans first used their fingers to count (See “Origin of Roman Numerals” section below for more). Still, they are derived from a base unit of 10, much like contemporary numbers.

Method

The method of numerical notation employed by the Romans is known as Roman numerals. They hire an additive (and subtractive) system where letters represent specific “base” numbers, and then combinations of symbols are used to describe arbitrary numbers. Sadly, nothing is known regarding the Roman number system’s genesis (Cajori 1993, p. 30).

The Latin letters employed in Roman numerals and the associated numerical values are listed in the following table.

History

Roman numerals might represent the number 1732 as MDCCXXXII, for instance. Roman numerals are not a strictly additive numbering system, though. In particular, such numbers are expressed by placing a sign for subtraction before the symbol for 5, 50, 10, 100, etc., rather than using four characters to represent a 4, 40, 9, 90, etc. (i.e., IIII, XXXX, VIIII, LXXXX, etc.). For instance, 4 denotes the IV, nine the IX, 40 the XL, etc. However, this rule is typically ignored on clock faces because IIII is more frequently found than IV. Additionally, the Romans virtually ever utilized the custom of putting smaller numbers before larger ones to denote value subtraction, but following the development of the printing machine, it gained favor in Europe (Wells 1986, p. 60; Cajori 1993, p. 31).

How To Convey

The Romans surrounded enormous numerals with a half-frame (open at the bottom) that signified the number should will multiply 100,000, as shown above (Menninger 1992, p. 44; Cajori 1993, p. 32). In more modern use, the strokes will occasionally write on the sides, as in |X| (Cajori 19993, p. 32). It’s also important to recall that the Romans never used the symbol M for 1000.

But they instead used (I) for 1000, (I)(I) for 2000, etc., as well as IM, IIM, etc., on occasion (Menninger 1992, p. 281; Cajori 1993, p. 32). However, the Middle Ages saw a significant increase in the usage of M. When multiplying numbers by 10, the Romans occasionally used numerous parenthesis, such as (I) for 1000, ((I)) for 10000, (((I))) for 100000, etc. (Cajori 1993, p. 33).

In some cases, the Romans would place a vinculum (known as a titulus in the Middle Ages) above a Roman number to denote multiplication by 1000; for example, I =1000, II =2000, etc. (Menninger 1992, p. 281; Cajori 1993, p. 32).

Conclusion

Roman numerals are only seldom seen in modern contexts, such as the release year of movies and the digits on the faces of watches and clocks. However, they do have the benefit of allowing addition to being perform “symbolically” (i.e., without concern for the “position” of a specific digit) by simply grouping all the symbols, writing groups of five Areas V, groups of two Vs. As X, etc.

The Wolfram Language’s IntegerString[n, “Roman”] function may be used to get the Roman numeral corresponding to the Hindu-Arabic number n.
