The answer
LVII
57 in Roman numerals is LVII.
How LVII is built
To write it, split 57 into 50 + 7. 50 is L, 7 is VII, so 57 is L then VII: LVII.
To read it, LVII has 4 chunks, and none of them is a take-away pair, so every chunk is added.
| Chunk | Worth | Why |
|---|---|---|
| L | 50 | Add |
| V | 5 | Add |
| I | 1 | Add |
| I | 1 | Add |
The mistake to watch for
Writing 57 as XXXXXVII
Wrong: XXXXXVII
XXXXXVII forgets L. Fifty has its own letter, and X can only be written three times in a row, so 50 is L, which makes 57 LVII.
