That is 5 symbol groups added together, reading left to right from the largest value down. ## How it breaks down *MMCMXX = 1000 + 1000 + 900 + 10 + 10 = 2,920* | Group | Value | Subtraction | Running total | | --- | --- | --- | --- | | M | 1,000 | — | 1,000 | | M | 1,000 | — | 2,000 | | CM | 900 | M − C | 2,900 | | X | 10 | — | 2,910 | | X | 10 | — | 2,920 | ## Why the smaller symbol comes first MMCMXX uses subtractive notation in one place: CM means M minus C, or 900. 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 | no | | X | 10 | yes — 2× | | L | 50 | no | | C | 100 | yes — 1× | | D | 500 | no | | M | 1,000 | yes — 3× | ## The same number, other ways - **In words:** Two thousand nine hundred twenty - **Roman numeral:** MMCMXX - **Symbol count:** 6 characters - **Binary:** 101101101000 - **Hexadecimal:** B68 ## The numbers either side | Number | Roman numeral | | --- | --- | | 2,918 | MMCMXVIII | | 2,919 | MMCMXIX | | 2,920 | MMCMXX ← | | 2,921 | MMCMXXI | | 2,922 | MMCMXXII | ## Common questions ### What is 2920 in Roman numerals? 2,920 is MMCMXX. ### What does MMCMXX mean?
