How it breaks down

CMLXVII = 900 + 50 + 10 + 5 + 1 + 1 = 967
Group	Value	Subtraction	Running total
CM	900	M − C	900
L	50	—	950
X	10	—	960
V	5	—	965
I	1	—	966
I	1	—	967

Why the smaller symbol comes first

CMLXVII 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.
