How it breaks down

CCCXCIV = 100 + 100 + 100 + 90 + 4 = 394
Group	Value	Subtraction	Running total
C	100	—	100
C	100	—	200
C	100	—	300
XC	90	C − X	390
IV	4	V − I	394

Why the smaller symbol comes first

CCCXCIV uses subtractive notation in 2 places: XC means C minus X, or 90; 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.
