How it breaks down

MMCDL = 1000 + 1000 + 400 + 50 = 2,450
Group	Value	Subtraction	Running total
M	1,000	—	1,000
M	1,000	—	2,000
CD	400	D − C	2,400
L	50	—	2,450

Why the smaller symbol comes first

MMCDL uses subtractive notation in one place: CD means D minus C, or 400. 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.
