That is 6 symbol groups added together, reading left to right from the largest value down. ## How it breaks down *MDCCCIV = 1000 + 500 + 100 + 100 + 100 + 4 = 1,804* | Group | Value | Subtraction | Running total | | --- | --- | --- | --- | | M | 1,000 | — | 1,000 | | D | 500 | — | 1,500 | | C | 100 | — | 1,600 | | C | 100 | — | 1,700 | | C | 100 | — | 1,800 | | IV | 4 | V − I | 1,804 | ## Why the smaller symbol comes first MDCCCIV uses subtractive notation in one place: IV means V minus I, or 4. 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 — 1× | | V | 5 | yes — 1× | | X | 10 | no | | L | 50 | no | | C | 100 | yes — 3× | | D | 500 | yes — 1× | | M | 1,000 | yes — 1× | ## The same number, other ways - **In words:** One thousand eight hundred four - **Roman numeral:** MDCCCIV - **Symbol count:** 7 characters - **Binary:** 11100001100 - **Hexadecimal:** 70C ## The numbers either side | Number | Roman numeral | | --- | --- | | 1,802 | MDCCCII | | 1,803 | MDCCCIII | | 1,804 | MDCCCIV ← | | 1,805 | MDCCCV | | 1,806 | MDCCCVI | ## Common questions ### What is 1804 in Roman numerals? 1,804 is MDCCCIV. ### What does MDCCCIV mean?
