That is 6 symbol groups added together, reading left to right from the largest value down. ## How it breaks down *MDXCVII = 1000 + 500 + 90 + 5 + 1 + 1 = 1,597* | Group | Value | Subtraction | Running total | | --- | --- | --- | --- | | M | 1,000 | — | 1,000 | | D | 500 | — | 1,500 | | XC | 90 | C − X | 1,590 | | V | 5 | — | 1,595 | | I | 1 | — | 1,596 | | I | 1 | — | 1,597 | ## Why the smaller symbol comes first MDXCVII uses subtractive notation in one place: 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 — 2× | | V | 5 | yes — 1× | | X | 10 | yes — 1× | | L | 50 | no | | C | 100 | yes — 1× | | D | 500 | yes — 1× | | M | 1,000 | yes — 1× | ## The same number, other ways - **In words:** One thousand five hundred ninety-seven - **Roman numeral:** MDXCVII - **Symbol count:** 7 characters - **Binary:** 11000111101 - **Hexadecimal:** 63D ## The numbers either side | Number | Roman numeral | | --- | --- | | 1,595 | MDXCV | | 1,596 | MDXCVI | | 1,597 | MDXCVII ← | | 1,598 | MDXCVIII | | 1,599 | MDXCIX | ## Common questions ### What is 1597 in Roman numerals? 1,597 is MDXCVII. ### What does MDXCVII mean?
