Number (1–3,999 for numerals)

Roman numeral

994 is written CMXCIV in Roman numerals. That is 3 symbol groups added together, reading left to right from the largest value down.

How it breaks down

CMXCIV = 900 + 90 + 4 = 994
Group	Value	Subtraction	Running total
CM	900	M − C	900
XC	90	C − X	990
IV	4	V − I	994

Why the smaller symbol comes first

CMXCIV uses subtractive notation in 3 places: CM means M minus C, or 900; XC means C minus X, or 90; 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.
