Group Value Subtraction Running total
M 1,000 1,000
M 1,000 2,000

XL 40 L − X 3,440
IX 9 X − I 3,449

Why the smaller symbol comes first

MMMCDXLIX uses subtractive notation in 3 places: CD means D minus C, or 400; XL means L minus X, or 40; IX means X minus I, or 9. 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.
