How it breaks down

MMCMLV = 1000 + 1000 + 900 + 50 + 5 = 2,955
Group	Value	Subtraction	Running total
M	1,000	—	1,000
M	1,000	—	2,000
CM	900	M − C	2,900
L	50	—	2,950
V	5	—	2,955

Why the smaller symbol comes first

MMCMLV uses subtractive notation in one place: CM means M minus C, or 900. 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.
