2,449 in Roman numerals
MMCDXLIX

2,449 is written MMCDXLIX in Roman numerals. That is 5 symbol groups added together, reading left to right from the largest value down.

How it breaks down

MMCDXLIX = 1000 + 1000 + 400 + 40 + 9 = 2,449
Group Value Subtraction Running total
M 1,000 — 1,000
M 1,000 — 2,000
CD 400 D − C 2,400
XL 40 L − X 2,440
IX 9 X − I 2,449

Why the smaller symbol comes first

MMCDXLIX uses subtractive notation in 3 places: CD means D minus C, or 400; XL means L minus X, or 40; 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.
