| Place | Value | Numeral | Rule used |

| thousands | 2000 | MM | the symbol repeated twice |
| tens | 10 | X | one symbol |
| ones | 9 | IX | subtractive: one symbol before the ten symbol |
Check MMXIX by reading it back
Reading MMXIX from left to right and adding the pieces: MM = 2000, X = 10, IX = 9. Together that is 2000 + 10 + 9 = 2019, so MMXIX and 2019 match.
Mistakes to avoid with MMXIX
- Do not write the 4s and 9s additively. 2019 uses subtractive pairs (
IXfor 9), not strings like IIII or VIIII. - Never repeat a symbol more than three times in a row. When a fourth would be needed, the subtractive form takes over.
- Only I, X and C may be placed before a larger symbol to subtract, so MMXIX never contains forms such as VX or LC.
- Read MMXIX as one number, not letter by letter: add the values left to right, except where a smaller symbol sits before a larger one.
