55 in Roman numerals
55 is written LV. In chunks: L (50) + V (5) = 55.
The answer
LV
55 in Roman numerals is LV.
How LV is built
To write it, split 55 into 50 + 5. 50 is L, 5 is V, so 55 is L then V: LV.
To read it, LV has 2 chunks, and none of them is a take-away pair, so every chunk is added.
| Chunk | Worth | Why |
|---|---|---|
| L | 50 | Add |
| V | 5 | Add |
The mistake to watch for
Writing 55 as XXXXXV
Wrong: XXXXXV
XXXXXV forgets L. Fifty has its own letter, and X can only be written three times in a row, so 50 is L, which makes 55 LV.
