That is 6 symbol groups added together, reading left to right from the largest value down. ## How it breaks down *CDXCVIII = 400 + 90 + 5 + 1 + 1 + 1 = 498* | Group | Value | Subtraction | Running total | | --- | --- | --- | --- | | CD | 400 | D − C | 400 | | XC | 90 | C − X | 490 | | V | 5 | — | 495 | | I | 1 | — | 496 | | I | 1 | — | 497 | | I | 1 | — | 498 | ## Why the smaller symbol comes first CDXCVIII uses subtractive notation in 2 places: CD means D minus C, or 400; XC means C minus X, or 90. 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 — 3× | | V | 5 | yes — 1× | | X | 10 | yes — 1× | | L | 50 | no | | C | 100 | yes — 2× | | D | 500 | yes — 1× | | M | 1,000 | no | ## The same number, other ways - **In words:** Four hundred ninety-eight - **Roman numeral:** CDXCVIII - **Symbol count:** 8 characters - **Binary:** 111110010 - **Hexadecimal:** 1F2 ## The numbers either side | Number | Roman numeral | | --- | --- | | 496 | CDXCVI | | 497 | CDXCVII | | 498 | CDXCVIII ← | | 499 | CDXCIX | | 500 | D | ## Common questions ### What is 498 in Roman numerals? 498 is CDXCVIII. ### What does CDXCVIII mean?
