How do you write 4 in Roman numerals?

Four is written as IV in Roman numerals. I (1) before V (5) means subtract: 5 − 1 = 4. Similarly, 9 = IX, 40 = XL, 90 = XC, 400 = CD, 900 = CM.

What is the largest Roman numeral?

Using standard notation, the largest is 3999 = MMMCMXCIX. To write 4000 and above, extended notations like vinculum (overline) are needed, which are not part of the standard system.

How do you read Roman numerals?

Add symbol values left to right. If a smaller symbol precedes a larger one, subtract it instead of adding (e.g. IV = 4, not 6). Otherwise just add: VIII = 5+1+1+1 = 8.

Roman Numeral Symbols

The seven Roman numeral symbols are: I (1), V (5), X (10), L (50), C (100), D (500), and M (1000). Roman numerals use subtractive notation for values like 4 (IV), 9 (IX), 40 (XL), 90 (XC), 400 (CD), and 900 (CM).

Step-by-Step Breakdown

For each conversion, the tool shows exactly which Roman numeral symbols were used and what value they represent. For example, 1994 = M (1000) + CM (900) + XC (90) + IV (4) = MCMXCIV.

Range

Standard Roman numerals cover 1 to 3999. The number 4000 would require a vinculum (overline) notation which is outside the standard system.
