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

L 50 — 2,450
X 10 — 2,460
X 10 — 2,470

Why the smaller symbol comes first

MMCDLXX 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.
