The numerical system of Roman letters consists of 7 Latin letters. They are I, V, X, L, C, D, and M. Here I represents 1, V represents 5, X represents 10, L represents 50, C represents 100, D represents 500, and M represents 1000.

Roman numerals use different symbols for each power of ten and there is no zero symbol, in contrast with the place value notation of Arabic numerals (in which place-keeping zeros enable the same digit to represent different powers of ten).

Rules of the Roman Numeral System

If a symbol is repeated, its value is added as many times as it occurs. For example, II=2, XX=20 etc. The symbols V, L and D are never repeated. A symbol is not repeated more than three times.

The Roman numeral system uses only seven symbols: I, V, X, L, C, D, and M. I represents the number 1, V represents 5, X is 10, L is 50, C is 100, D is 500, and M is 1,000. Different arrangements of these seven symbols represent different numbers. The numbers 1–10 are: 1 = I.

The absence of zero and irrational numbers, impractical and inaccurate fractions, and difficulties with multiplication and division prevented the Romans and the Europeans who later used the system from making advances in number theory and geometry as the Greeks had done in the Pythagorean and Euclidean schools.

The number 500 in Roman Numerals is directly represented by the letter D. Hence, there is no method to perform addition or subtraction for D Roman Numerals. Thus, the numerical value of D Roman Numerals is 500.

Another common mistake is adding all values of the numerals together, instead of subtracting the value of any smaller numeral that comes before a larger numeral. For example, a child might read LIX as 61, rather than 59. The third most common error is using more than three repeated numerals next to each other.
