How it breaks down

MXLVI = 1000 + 40 + 5 + 1 = 1,046
Group	Value	Subtraction	Running total
M	1,000	—	1,000
XL	40	L − X	1,040
V	5	—	1,045
I	1	—	1,046

Why the smaller symbol comes first

MXLVI 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.
