104 in Roman numerals

104 in Roman numerals
CIV

104 is written CIV in Roman numerals. That is 2 symbol groups added together, reading left to right from the largest value down.

How it breaks down

CIV = 100 + 4 = 104
Group Value Subtraction Running total
C 100 100
IV 4 V − I 104

Why the smaller symbol comes first

CIV 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.
