The answer
LXXV
75 in Roman numerals is LXXV.
How LXXV is built
To write it, split 75 into 70 + 5. 70 is LXX, 5 is V, so 75 is LXX then V: LXXV.
To read it, LXXV has 4 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 |
| V | 5 | Add |
The mistake to watch for
Writing 75 as XXXXXXXV
Wrong: XXXXXXXV
XXXXXXXV forgets L. Fifty has its own letter, and X can only be written three times in a row, so 70 is LXX, which makes 75 LXXV.
