The answer
LXXIII
73 in Roman numerals is LXXIII.
How LXXIII is built
To write it, split 73 into 70 + 3. 70 is LXX, 3 is III, so 73 is LXX then III: LXXIII.
To read it, LXXIII has 6 chunks, and none of them is a take-away pair, so every chunk is added.
| Chunk | Worth | Why |
|---|---|---|
| L | 50 | Add |
| X | 10 | Add |
| X | 10 | Add |
| I | 1 | Add |
| I | 1 | Add |
| I | 1 | Add |
The mistake to watch for
Writing 73 as XXXXXXXIII
Wrong: XXXXXXXIII
XXXXXXXIII forgets L. Fifty has its own letter, and X can only be written three times in a row, so 70 is LXX, which makes 73 LXXIII.
