Number (1–3,999 for numerals)

Roman numeral

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

How it breaks down

CLXXXIV = 100 + 50 + 10 + 10 + 10 + 4 = 184
Group	Value	Subtraction	Running total
C	100	—	100
L	50	—	150
X	10	—	160
X	10	—	170
X	10	—	180
IV	4	V − I	184

Why the smaller symbol comes first

CLXXXIV uses subtractive notation in one place: 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.
