460 in Roman numerals
CDLX

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

How it breaks down

CDLX = 400 + 50 + 10 = 460
Group Value Subtraction Running total
CD 400 D − C 400
L 50 450
X 10 460

Why the smaller symbol comes first

CDLX uses subtractive notation in one place: CD means D minus C, or 400. 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.
