LXXXIX in numbers
LXXXIX = 89.
Eighty-nine written as a Roman numeral.
89 in words: Eighty-nine
Eighty-nine, L (50) + XXX (30) + IX (9). The sting is the ending: IX is nine written as one-before-ten, not I followed by X. Read LXXX as eighty, then treat IX as a single unit for nine. It sits one short of XC (90) and is frequently searched by its letters, often next to LXXXIV.

How to read LXXXIX
Roman numerals are read left to right, largest value first, adding as you go. Scanning LXXXIX one group at a time gives a running total that lands on 89:
| Read | Worth | Running total |
|---|---|---|
| LXXX | 80 | 80 |
| IX | 9 | 89 |
The one place that scan can trip you up is the pair IX. A smaller letter sitting in front of a larger one is subtracted, not added, so you have to read those two letters as a single unit rather than one at a time. Treat IX as one group and the rest of LXXXIX falls into place.
