# 745 in Roman numerals

**745 in Roman numerals: DCCXLV**

745 is written DCCXLV in Roman numerals. That is 5 symbol groups added together, reading left to right from the largest value down.

## How it breaks down

*DCCXLV = 500 + 100 + 100 + 40 + 5 = 745*

| Group | Value | Subtraction | Running total |
| --- | --- | --- | --- |
| D | 500 | — | 500 |
| C | 100 | — | 600 |
| C | 100 | — | 700 |
| XL | 40 | L − X | 740 |
| V | 5 | — | 745 |

## Why the smaller symbol comes first

DCCXLV uses subtractive notation in one place: XL means L minus X, or 40. 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

| Symbol | Value | Used here |
| --- | --- | --- |
| I | 1 | no |
| V | 5 | yes — 1× |
| X | 10 | yes — 1× |
| L | 50 | yes — 1× |
| C | 100 | yes — 2× |
| D | 500 | yes — 1× |
| M | 1,000 | no |
