519 in Roman numerals
DXIX

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

How it breaks down

DXIX = 500 + 10 + 9 = 519
Group Value Subtraction Running total
D 500 500
X 10 510
IX 9 X − I 519

Why the smaller symbol comes first

DXIX 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.
