How it breaks down

MMCMXII = 1000 + 1000 + 900 + 10 + 1 + 1 = 2,912
Group Value Subtraction Running total
M 1,000 — 1,000
M 1,000 — 2,000
CM 900 M − C 2,900
X 10 — 2,910
I 1 — 2,911
I 1 — 2,912

Why the smaller symbol comes first

MMCMXII 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.
