The answer
LIII
53 in Roman numerals is LIII.
How LIII is built
To write it, split 53 into 50 + 3. 50 is L, 3 is III, so 53 is L then III: LIII.
To read it, LIII has 4 chunks, and none of them is a take-away pair, so every chunk is added.
| Chunk | Worth | Why |
|---|---|---|
| L | 50 | Add |
| I | 1 | Add |
| I | 1 | Add |
| I | 1 | Add |
The mistake to watch for
Writing 53 as XXXXXIII
Wrong: XXXXXIII
XXXXXIII forgets L. Fifty has its own letter, and X can only be written three times in a row, so 50 is L, which makes 53 LIII.
