That is 4 symbol groups added together, reading left to right from the largest value down. ## How it breaks down *XLVII = 40 + 5 + 1 + 1 = 47* | Group | Value | Subtraction | Running total | | --- | --- | --- | --- | | XL | 40 | L − X | 40 | | V | 5 | — | 45 | | I | 1 | — | 46 | | I | 1 | — | 47 | ## Why the smaller symbol comes first XLVII uses subtractive notation in one place: XL means L minus X, or 40. 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 | yes — 1× | | L | 50 | yes — 1× | | C | 100 | no | | D | 500 | no | | M | 1,000 | no | ## The same number, other ways - **In words:** Forty-seven - **Roman numeral:** XLVII - **Symbol count:** 5 characters - **Binary:** 101111 - **Hexadecimal:** 2F ## The numbers either side | Number | Roman numeral | | --- | --- | | 45 | XLV | | 46 | XLVI | | 47 | XLVII ← | | 48 | XLVIII | | 49 | XLIX | ## Common questions ### What is 47 in Roman numerals? 47 is XLVII. ### What does XLVII mean?
