59 in Roman numerals
LIX

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

How it breaks down

LIX = 50 + 9 = 59
Group Value Subtraction Running total
L 50 50
IX 9 X − I 59

Why the smaller symbol comes first

LIX uses subtractive notation in one place: IX means X minus I, or 9. 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.
