The answer
LXVIII
68 in Roman numerals is LXVIII.
How LXVIII is built
To write it, split 68 into 60 + 8. 60 is LX, 8 is VIII, so 68 is LX then VIII: LXVIII.
To read it, LXVIII 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 |
| V | 5 | Add |
| I | 1 | Add |
| I | 1 | Add |
| I | 1 | Add |
The mistake to watch for
Writing 68 as LXIIX
Wrong: LXIIX
LXIIX tries to take two I's away from X. Only one smaller letter can go in front of a bigger one, so 8 is VIII (5 + 3), which makes 68 LXVIII.
