How XXIX is formed
| Place | Value | Symbols |
|---|---|---|
| Tens | 20 | XX |
| Units | 9 | I (subtracted)X |
| Total | 29 | XXIX |
XXIX is written one place at a time, from the largest to the smallest: XX (20) + IX (9) = 29.
IX is the only subtraction: the I before the X takes away 1, so IX = 9.
Common mistakes
Wrong: XXVIIII
Why isn't 29 written as XXVIIII?
A symbol can't be repeated four times in a row. 9 is IX (10 − 1), not VIIII, so 29 is XXIX.
