984 in Roman numerals
CMLXXXIV

984 is written CMLXXXIV in Roman numerals. That is 6 symbol groups added together, reading left to right from the largest value down.

How it breaks down

CMLXXXIV = 900 + 50 + 10 + 10 + 10 + 4 = 984
Group Value Subtraction Running total
CM 900 M − C 900
L 50 — 950
X 10 — 960
X 10 — 970
X 10 — 980
IV 4 V − I 984

Why the smaller symbol comes first

CMLXXXIV uses subtractive notation in 2 places: CM means M minus C, or 900; 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.
