How it breaks down

Group Value Subtraction Running total
M 1,000 1,000

CD 400 D − C 3,400
IV 4 V − I 3,404

Why the smaller symbol comes first

MMMCDIV uses subtractive notation in 2 places: CD means D minus C, or 400; 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.
