The answer
LXV
65 in Roman numerals is LXV.
How LXV is built
To write it, split 65 into 60 + 5. 60 is LX, 5 is V, so 65 is LX then V: LXV.
To read it, LXV has 3 chunks, and none of them is a take-away pair, so every chunk is added.
| Chunk | Worth | Why |
|---|---|---|
| L | 50 | Add |
| X | 10 | Add |
| V | 5 | Add |
The mistake to watch for
Writing 65 as XXXXXXV
Wrong: XXXXXXV
XXXXXXV forgets L. Fifty has its own letter, and X can only be written three times in a row, so 60 is LX, which makes 65 LXV.
