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

CM 900 M − C 3,900
XC 90 C − X 3,990
IV 4 V − I 3,994

Why the smaller symbol comes first

MMMCMXCIV uses subtractive notation in 3 places: CM means M minus C, or 900; 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.
