How it breaks down

MMDLIV = 1000 + 1000 + 500 + 50 + 4 = 2,554
Group	Value	Subtraction	Running total
M	1,000	—	1,000

D	500	—	2,500
L	50	—	2,550
IV	4	V − I	2,554

Why the smaller symbol comes first

MMDLIV uses subtractive notation in one place: IV means V minus I, or 4. 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.
