How it breaks down

MMCMVI = 1000 + 1000 + 900 + 5 + 1 = 2,906
Group	Value	Subtraction	Running total
M	1,000	—	1,000
M	1,000	—	2,000
CM	900	M − C	2,900
V	5	—	2,905
I	1	—	2,906

Why the smaller symbol comes first

MMCMVI 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.
