Roman Letters
Roman letters are derived from the English alphabet, but not all English letters are considered Roman. Out of the 26 English alphabets, 23 are recognized as Roman letters, with J, U, and W being exceptions. Therefore, the Roman letters are as follows: A, B, C, D, E, F, G, H, I, K, L, M, N, O, P, Q, R, S, T, V, X, Y, and Z. These letters are also referred to as Roman symbols.
Rules for Writing Roman Numerals
- Basic Symbols: The basic symbols and their values are:
I = 1V = 5X = 10L = 50C = 100D = 500M = 1000
- Addition: When a smaller numeral is placed before a larger one, its value is subtracted from the larger numeral. For example,
IV = 4(5 - 1). - Subtraction: When a smaller numeral follows a larger one, their values are added together. For example,
VI = 6(5 + 1). - Repetition: The same numeral can be repeated up to three times to increase its value. For example,
III = 3, andXXX = 30. - Limitations on Repetition: Numerals like
V,L, andDare never repeated because their values are already substantial (5, 50, and 500, respectively). - Combining Symbols: Larger numbers are created by combining these symbols according to these rules. For example,
LVIII = 58(50 + 5 + 3).
