Your Roman number:
In Roman Numerals, a number consists of the symbols (or letters/characters) C, D, I, L, M, V, X written in a specific order. We see Roman numerals everywhere  clocks, school classes, musical chords, historical dates, legal documents, astronomy, and even cricket team names. Based on the ancient Roman system, Roman numerals are the symbols used in numerical notation. Check out the table below to see how they correlate.
In these numerals, letters are used together to represent numbers. An example of a roman numeral is XLVIII which is equivalent to 48 in numeric form. The Roman numerals use a combination of symbols, including the English alphabet. As an example, 5 in roman numeral is denoted by V. It may be used for anything, including Class I, Class II, Class X, etc.
In Roman Numerals, a number consists of the symbols (or letters/characters) C, D, I, L, M, V, X written in a specific order.
1.) An "I" before an "V" or "X" represents one less, so four is IV (one less than 5), and nine is IX (one less than 10) if "I" comes before an "V" or "X".
2.) The "X" before L or C represents ten less, so 40 is XL (10 less than 50), and 90 is XC (10 less than 100).
3.) In the case of "C" placed before D or M, it represents a hundred less, so 400 is CD (100 less than 500), and 900 is CM (100 less than 1000).
