Roman Numeral Symbol Values & Subtractive Rules

Standard Roman numerals use additive and subtractive combinations:

How to Convert a Number into Roman Numerals

1. Break the Number into Place Values: Separate the number into thousands, hundreds, tens, and ones (for example, 2026 = 2000 + 20 + 6).
2. Match Each Part to Roman Symbols: Convert each place value from largest to smallest using additive symbols or subtractive pairs (for 4s and 9s).
3. Combine the Symbols: Concatenate the letters from left to right.

Worked Example: To write 2026 in Roman numerals: 2000 = MM, 20 = XX, and 6 = VI, giving MMXXVI.

Frequently Asked Questions (FAQ)

Why is 3,999 the largest standard Roman numeral?

Because a symbol cannot be repeated more than three times in a row (MMM = 3000), and there is no standard single-letter ASCII symbol above M (1000) without using overline vinculum notation.
