Roman numeral

1,444 is written MCDXLIV in Roman numerals. That is 4 symbol groups added together, reading left to right from the largest value down.

How it breaks down

MCDXLIV = 1000 + 400 + 40 + 4 = 1,444
Group	Value	Subtraction	Running total
M	1,000	—	1,000
CD	400	D − C	1,400
XL	40	L − X	1,440
IV	4	V − I	1,444

Why the smaller symbol comes first

MCDXLIV uses subtractive notation in 3 places: CD means D minus C, or 400; XL means L minus X, or 40; IV means V minus I, or 4. 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.
