Roman numeral

469 is written CDLXIX in Roman numerals. That is 4 symbol groups added together, reading left to right from the largest value down.

How it breaks down

CDLXIX = 400 + 50 + 10 + 9 = 469
Group	Value	Subtraction	Running total
CD	400	D − C	400
L	50	—	450
X	10	—	460
IX	9	X − I	469

Why the smaller symbol comes first

CDLXIX uses subtractive notation in 2 places: CD means D minus C, or 400; 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.
