That is 5 symbol groups added together, reading left to right from the largest value down. ## How it breaks down *MCDVII = 1000 + 400 + 5 + 1 + 1 = 1,407* | Group | Value | Subtraction | Running total | | --- | --- | --- | --- | | M | 1,000 | — | 1,000 | | CD | 400 | D − C | 1,400 | | V | 5 | — | 1,405 | | I | 1 | — | 1,406 | | I | 1 | — | 1,407 | ## Why the smaller symbol comes first MCDVII 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 | yes — 2× | | V | 5 | yes — 1× | | X | 10 | no | | 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 four hundred seven - **Roman numeral:** MCDVII - **Symbol count:** 6 characters - **Binary:** 10101111111 - **Hexadecimal:** 57F ## The numbers either side | Number | Roman numeral | | --- | --- | | 1,405 | MCDV | | 1,406 | MCDVI | | 1,407 | MCDVII ← | | 1,408 | MCDVIII | | 1,409 | MCDIX | ## Common questions ### What is 1407 in Roman numerals? 1,407 is MCDVII. ### What does MCDVII mean?
