The answer
XXXVII
37 in Roman numerals is XXXVII.
How XXXVII is built
To write it, split 37 into 30 + 7. 30 is XXX, 7 is VII, so 37 is XXX then VII: XXXVII.
To read it, XXXVII has 6 chunks, and none of them is a take-away pair, so every chunk is added.
| Chunk | Worth | Why |
|---|---|---|
| X | 10 | Add |
| X | 10 | Add |
| X | 10 | Add |
| V | 5 | Add |
| I | 1 | Add |
| I | 1 | Add |
The mistake to watch for
Writing 37 as XXXIIIIIII
Wrong: XXXIIIIIII
XXXIIIIIII counts in ones, like a tally, and writes I more than three times in a row. Use V for five: 7 is VII, which makes 37 XXXVII.
