# Roman numerals

Roman numerals use seven symbols. Every number from 1 to 3,999 is built by adding them left to right, largest first, with six exceptions where a smaller symbol comes first and is subtracted instead.

## The seven symbols

| Symbol | Value |
| --- | --- |
| I | 1 |
| V | 5 |
| X | 10 |
| L | 50 |
| C | 100 |
| D | 500 |
| M | 1,000 |

## The six subtractive pairs

*No other subtractive combination is standard. IC and IIII are both wrong.*

| Pair | Value | Reads as |
| --- | --- | --- |
| IV | 4 | V − I |
| IX | 9 | X − I |
| XL | 40 | L − X |
| XC | 90 | C − X |
| CD | 400 | D − C |
| CM | 900 | M − C |

The system stops at 3,999 here because larger numbers need a vinculum — a bar drawn over a numeral to multiply it by a thousand — which has no settled plain-text form.

## Common questions

### Why is 4 written IV and not IIII?

Because standard notation never repeats a symbol four times. Placing I before V subtracts it, giving 4 in two characters instead of four. Clock faces are the well-known exception and often use IIII for visual balance.

### Is there a Roman numeral for zero?

No. The system has no symbol for zero and no concept of it as a number — Roman numerals record quantities, and a quantity of nothing was simply not written.

### What is the largest Roman numeral?

In standard plain notation, 3,999 — MMMCMXCIX. Beyond that a vinculum over a numeral multiplies it by a thousand, but that requires an overbar rather than ordinary letters.
