1,040 in Roman numerals
MXL

1,040 is written MXL in Roman numerals. That is 2 symbol groups added together, reading left to right from the largest value down.

How it breaks down

MXL = 1000 + 40 = 1,040
Group Value Subtraction Running total
M 1,000 1,000
XL 40 L − X 1,040

Why the smaller symbol comes first

MXL uses subtractive notation in one place: XL means L minus X, or 40. 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.
