590 in Roman numerals
DXC

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

How it breaks down

DXC = 500 + 90 = 590
Group Value Subtraction Running total
D 500 500
XC 90 C − X 590

Why the smaller symbol comes first

DXC uses subtractive notation in one place: XC means C minus X, or 90. 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.
