That is 5 symbol groups added together, reading left to right from the largest value down. ## How it breaks down *CDXXXV = 400 + 10 + 10 + 10 + 5 = 435* | Group | Value | Subtraction | Running total | | --- | --- | --- | --- | | CD | 400 | D − C | 400 | | X | 10 | — | 410 | | X | 10 | — | 420 | | X | 10 | — | 430 | | V | 5 | — | 435 | ## Why the smaller symbol comes first CDXXXV uses subtractive notation in one place: CD means D minus C, or 400. 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 — 3× | | L | 50 | no | | C | 100 | yes — 1× | | D | 500 | yes — 1× | | M | 1,000 | no | ## The same number, other ways - **In words:** Four hundred thirty-five - **Roman numeral:** CDXXXV - **Symbol count:** 6 characters - **Binary:** 110110011 - **Hexadecimal:** 1B3 ## The numbers either side | Number | Roman numeral | | --- | --- | | 433 | CDXXXIII | | 434 | CDXXXIV | | 435 | CDXXXV ← | | 436 | CDXXXVI | | 437 | CDXXXVII | ## Common questions ### What is 435 in Roman numerals? 435 is CDXXXV. ### What does CDXXXV mean?
