How it breaks down

DCCCXIV = 500 + 100 + 100 + 100 + 10 + 4 = 814
Group	Value	Subtraction	Running total
D	500	—	500
C	100	—	600
C	100	—	700
C	100	—	800
X	10	—	810
IV	4	V − I	814

Why the smaller symbol comes first

DCCCXIV uses subtractive notation in one place: IV means V minus I, or 4. 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.
