Roman numeral

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

How it breaks down

CMXLI = 900 + 40 + 1 = 941
Group	Value	Subtraction	Running total
CM	900	M − C	900
XL	40	L − X	940
I	1	—	941

Why the smaller symbol comes first

CMXLI uses subtractive notation in 2 places: CM means M minus C, or 900; XL means L minus X, or 40. 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.
