54 in Roman numerals

54 in Roman numerals
LIV

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

How it breaks down

LIV = 50 + 4 = 54
Group Value Subtraction Running total
L 50 50
IV 4 V − I 54

Why the smaller symbol comes first

LIV 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.
