That is 8 symbol groups added together, reading left to right from the largest value down. ## How it breaks down *MMCDXVIII = 1000 + 1000 + 400 + 10 + 5 + 1 + 1 + 1 = 2,418* | Group | Value | Subtraction | Running total | | --- | --- | --- | --- | | M | 1,000 | — | 1,000 | | M | 1,000 | — | 2,000 | | CD | 400 | D − C | 2,400 | | X | 10 | — | 2,410 | | V | 5 | — | 2,415 | | I | 1 | — | 2,416 | | I | 1 | — | 2,417 | | I | 1 | — | 2,418 | ## Why the smaller symbol comes first MMCDXVIII 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 — 3× | | V | 5 | yes — 1× | | X | 10 | yes — 1× | | L | 50 | no | | C | 100 | yes — 1× | | D | 500 | yes — 1× | | M | 1,000 | yes — 2× | ## The same number, other ways - **In words:** Two thousand four hundred eighteen - **Roman numeral:** MMCDXVIII - **Symbol count:** 9 characters - **Binary:** 100101110010 - **Hexadecimal:** 972 ## The numbers either side | Number | Roman numeral | | --- | --- | | 2,416 | MMCDXVI | | 2,417 | MMCDXVII | | 2,418 | MMCDXVIII ← | | 2,419 | MMCDXIX | | 2,420 | MMCDXX | ## Common questions ### What is 2418 in Roman numerals? 2,418 is MMCDXVIII. ### What does MMCDXVIII mean?
