Roman Numerals
History and Introduction
Roman numerals originated in ancient Rome and remained the usual way of writing numbers throughout Europe well into the Late Middle Ages. Numbers in this system are represented by combinations of letters from the Latin alphabet. Roman numerals, as used today, are based on seven symbols: I, V, X, L, C, D, and M.
The system is decimal but not directly positional and does not include a zero. Roman numerals are based on combinations of these letters to represent values. The basic principle of the Roman numeral system is the additive and subtractive principles. Numbers are formed by combining symbols and adding their values, but to avoid four characters being repeated in succession (such as IIII or XXXX), subtractive notation is used: for example, IV is four and IX is nine.
Understanding Roman Numerals
To read Roman numerals, combine the symbols and their values starting from the left. If a symbol is followed by one of equal or lesser value, add the values. If a symbol is followed by one of greater value, subtract the value of the first from the second. The main symbols are I (1), V (5), X (10), L (50), C (100), D (500), and M (1000).
1  5  10  50  100  500  1000 
I  V  X  L  C  D  M 
For instance, the numeral II is equal to 2, XI is 11 (10 + 1), and IX is 9 (10  1). Larger numbers are constructed by placing a dash over a symbol to signify it should be multiplied by 1,000. Thus, V̅ represents 5,000 and X̅ represents 10,000.

Calculations with Roman Numerals
Calculating with Roman numerals can be challenging because the system lacks a zero and is not designed for complex arithmetic. Basic operations like addition and subtraction involve combining or removing symbols and adjusting the results to maintain proper form. For example, to add XVII (17) and VI (6), combine the symbols to XVIIII, then adjust to XXIII (23). Subtraction involves a similar process of removing symbols and adjusting as needed.
For more complex operations like multiplication and division, it's often easier to convert to Arabic numerals, perform the operation, and convert back. The Roman numeral system is elegant for certain applications like clock faces, but its utility in modern arithmetic is limited.
