How it breaks down

MMXCVII = 1000 + 1000 + 90 + 5 + 1 + 1 = 2,097
Group	Value	Subtraction	Running total
M	1,000	—	1,000
M	1,000	—	2,000
XC	90	C − X	2,090
V	5	—	2,095
I	1	—	2,096
I	1	—	2,097

Why the smaller symbol comes first

MMXCVII uses subtractive notation in one place: 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.
