1,009 in Roman numerals
MIX

1,009 is written MIX in Roman numerals. That is 2 symbol groups added together, reading left to right from the largest value down.

How it breaks down

MIX = 1000 + 9 = 1,009
Group Value Subtraction Running total
M 1,000 1,000
IX 9 X − I 1,009

Why the smaller symbol comes first

MIX 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.
