That is 6 symbol groups added together, reading left to right from the largest value down. ## How it breaks down *DCCXXIV = 500 + 100 + 100 + 10 + 10 + 4 = 724* | Group | Value | Subtraction | Running total | | --- | --- | --- | --- | | D | 500 | — | 500 | | C | 100 | — | 600 | | C | 100 | — | 700 | | X | 10 | — | 710 | | X | 10 | — | 720 | | IV | 4 | V − I | 724 | ## Why the smaller symbol comes first DCCXXIV uses subtractive notation in one place: 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 | Symbol | Value | Used here | | --- | --- | --- | | I | 1 | yes — 1× | | V | 5 | yes — 1× | | X | 10 | yes — 2× | | L | 50 | no | | C | 100 | yes — 2× | | D | 500 | yes — 1× | | M | 1,000 | no | ## The same number, other ways - **In words:** Seven hundred twenty-four - **Roman numeral:** DCCXXIV - **Symbol count:** 7 characters - **Binary:** 1011010100 - **Hexadecimal:** 2D4 ## The numbers either side | Number | Roman numeral | | --- | --- | | 722 | DCCXXII | | 723 | DCCXXIII | | 724 | DCCXXIV ← | | 725 | DCCXXV | | 726 | DCCXXVI | ## Common questions ### What is 724 in Roman numerals? 724 is DCCXXIV. ### What does DCCXXIV mean?
