How it breaks down

MDXCIV = 1000 + 500 + 90 + 4 = 1,594
Group	Value	Subtraction	Running total
M	1,000	—	1,000
D	500	—	1,500
XC	90	C − X	1,590
IV	4	V − I	1,594

Why the smaller symbol comes first

MDXCIV uses subtractive notation in 2 places: 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.
