141 in Roman numerals
CXLI

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

How it breaks down

CXLI = 100 + 40 + 1 = 141
Group Value Subtraction Running total
C 100 100
XL 40 L − X 140
I 1 141

Why the smaller symbol comes first

CXLI uses subtractive notation in one place: 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.
