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

V 5 — 2,995
I 1 — 2,996
I 1 — 2,997

Why the smaller symbol comes first

MMCMXCVII uses subtractive notation in 2 places: CM means M minus C, or 900; XC means C minus X, or 90. 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.
