2,291 is written MMCCXCI in Roman numerals. That is 6 symbol groups added together, reading left to right from the largest value down.

How it breaks down

MMCCXCI = 1000 + 1000 + 100 + 100 + 90 + 1 = 2,291
Group Value Subtraction Running total
M 1,000 — 1,000
M 1,000 — 2,000
C 100 — 2,100
C 100 — 2,200
XC 90 C − X 2,290
I 1 — 2,291

Why the smaller symbol comes first

MMCCXCI uses subtractive notation in one place: XC means C minus X, or 90. 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.
