That is 4 symbol groups added together, reading left to right from the largest value down. ## How it breaks down *MCDXV = 1000 + 400 + 10 + 5 = 1,415* | Group | Value | Subtraction | Running total | | --- | --- | --- | --- | | M | 1,000 | — | 1,000 | | CD | 400 | D − C | 1,400 | | X | 10 | — | 1,410 | | V | 5 | — | 1,415 | ## Why the smaller symbol comes first MCDXV 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 — 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 four hundred fifteen - **Roman numeral:** MCDXV - **Symbol count:** 5 characters - **Binary:** 10110000111 - **Hexadecimal:** 587 ## The numbers either side | Number | Roman numeral | | --- | --- | | 1,413 | MCDXIII | | 1,414 | MCDXIV | | 1,415 | MCDXV ← | | 1,416 | MCDXVI | | 1,417 | MCDXVII | ## Common questions ### What is 1415 in Roman numerals? 1,415 is MCDXV. ### What does MCDXV mean?
