# 464 in Roman numerals

**464 in Roman numerals: CDLXIV**

464 is written CDLXIV in Roman numerals. That is 4 symbol groups added together, reading left to right from the largest value down.

## How it breaks down

*CDLXIV = 400 + 50 + 10 + 4 = 464*

| Group | Value | Subtraction | Running total |
| --- | --- | --- | --- |
| CD | 400 | D − C | 400 |
| L | 50 | — | 450 |
| X | 10 | — | 460 |
| IV | 4 | V − I | 464 |

## Why the smaller symbol comes first

CDLXIV uses subtractive notation in 2 places: CD means D minus C, or 400; IV means V minus I, or 4. A smaller symbol placed before a larger one is subtracted from it rather than added, which is why IX is nine and not eleven.

Only six such pairs are valid — IV, IX, XL, XC, CD and CM. That restriction is what makes the notation unambiguous: IIII and IC both look like they should work, but neither is standard, and only one spelling of any number is correct.

## The symbols

| L | 50 | yes — 1× |
| C | 100 | yes — 1× |
