54 in Roman numerals
54 is written LIV. In chunks: L (50) + IV (4) = 54.
The answer
LIV
54 in Roman numerals is LIV.
How LIV is built
To write it, split 54 into 50 + 4. 50 is L, 4 is IV, so 54 is L then IV: LIV.
To read it, LIV has 2 chunks, and IV is a take-away pair, worked out first and then added.
| Chunk | Worth | Why |
|---|---|---|
| L | 50 | Add |
| IV | 4 | I before V: take away |
The mistake to watch for
Writing 54 as LIIII
Wrong: LIIII
LIIII writes I four times in a row. Never more than three: 4 is IV, one before five, which makes 54 LIV.
