Group Value Subtraction Running total
M 1,000 — 1,000
M 1,000 — 2,000
CM 900 M − C 2,900

V 5 — 2,945
I 1 — 2,946
I 1 — 2,947

Why the smaller symbol comes first

MMCMXLVII uses subtractive notation in 2 places: CM means M minus C, or 900; XL means L minus X, or 40. 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.
