How it breaks down

MCMXCVI = 1000 + 900 + 90 + 5 + 1 = 1,996
Group	Value	Subtraction	Running total
M	1,000	—	1,000
CM	900	M − C	1,900
XC	90	C − X	1,990
V	5	—	1,995
I	1	—	1,996

Why the smaller symbol comes first

MCMXCVI uses subtractive notation in 2 places: CM means M minus C, or 900; XC means C minus X, or 90. 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.
