The answer
LXXI

How LXXI is built
To write it, split 71 into 70 + 1. 70 is LXX, 1 is I, so 71 is LXX then I: LXXI.
To read it, LXXI 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 |
| I | 1 | Add |
The mistake to watch for
Writing 71 as LXIX
Wrong: LXIX
LXIX has the same letters in a different order, and order matters. A smaller letter before a bigger one means take away, so LXIX is 69, not 71. 71 is LXXI.
