How MMDXLV is formed
| Place | Value | Symbols |
|---|---|---|
| Thousands | 2000 | MM |
| Hundreds | 500 | D |
| Tens | 40 | X (subtracted)L |
| Units | 5 | V |
| Total | 2545 | MMDXLV |
MMDXLV is written one place at a time, from the largest to the smallest: MM (2000) + D (500) + XL (40) + V (5) = 2545.
XL is the only subtraction: the X before the L takes away 10, so XL = 40.
Common mistakes
Wrong: MMDVL
Why isn't 2545 written as MMDVL?
V is never subtracted; only I, X and C can come before a larger symbol. Write each place separately: MM (2000) + D (500) + XL (40) + V (5) = MMDXLV.
Wrong: MMDXXXXV
Why isn't 2545 written as MMDXXXXV?
A symbol can't be repeated four times in a row. 40 is XL (50 − 10), not XXXX, so 2545 is MMDXLV.
