How it breaks down

MMCDXCII = 1000 + 1000 + 400 + 90 + 1 + 1 = 2,492
Group Value Subtraction Running total
M 1,000 — 1,000
M 1,000 — 2,000
CD 400 D − C 2,400
XC 90 C − X 2,490
I 1 — 2,491
I 1 — 2,492

Why the smaller symbol comes first

MMCDXCII uses subtractive notation in 2 places: CD means D minus C, or 400; 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.
