How it breaks down

MMMXLIX = 1000 + 1000 + 1000 + 40 + 9 = 3,049
Group	Value	Subtraction	Running total
M	1,000	—	1,000
M	1,000	—	2,000
M	1,000	—	3,000
XL	40	L − X	3,040
IX	9	X − I	3,049

Why the smaller symbol comes first

MMMXLIX uses subtractive notation in 2 places: 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.
