Roman numeral

How it breaks down

MLXIX = 1000 + 50 + 10 + 9 = 1,069
Group	Value	Subtraction	Running total
M	1,000	—	1,000
L	50	—	1,050
X	10	—	1,060
IX	9	X − I	1,069

Why the smaller symbol comes first

MLXIX uses subtractive notation in one place: IX means X minus I, or 9. A smaller symbol placed before a larger one is subtracted from it rather than added, which is why IX is nine and not eleven.

Only six such pairs are valid — IV, IX, XL, XC, CD and CM. That restriction is what makes the notation unambiguous: IIII and IC both look like they should work, but neither is standard, and only one spelling of any number is correct.
