How LXIX is formed
| Place | Value | Symbols |
|---|---|---|
| Tens | 60 | LX |
| Units | 9 | I (subtracted)X |
| Total | 69 | LXIX |
LXIX is written one place at a time, from the largest to the smallest: LX (60) + IX (9) = 69.
IX is the only subtraction: the I before the X takes away 1, so IX = 9.
Common mistakes
Wrong: LXVIIII
Why isn't 69 written as LXVIIII?
A symbol can't be repeated four times in a row. 9 is IX (10 − 1), not VIIII, so 69 is LXIX.
