How it breaks down

DCXCII = 500 + 100 + 90 + 1 + 1 = 692
Group	Value	Subtraction	Running total
D	500	—	500
C	100	—	600
XC	90	C − X	690
I	1	—	691
I	1	—	692

Why the smaller symbol comes first

DCXCII 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.
