MDCCCXLIV is written one place at a time, from the largest to the smallest: M (1000) + DCCC (800) + XL (40) + IV (4) = 1844.

XL and IV are subtractive pairs: in each one the smaller symbol comes first and is taken away.

Common mistakes

Wrong: MDCCCXXXXIV

Why isn't 1844 written as MDCCCXXXXIV?

A symbol can't be repeated four times in a row. 40 is XL (50 − 10), not XXXX, so 1844 is MDCCCXLIV.

Wrong: MDCCCXLIIII

Why isn't 1844 written as MDCCCXLIIII?

A symbol can't be repeated four times in a row. 4 is IV (5 − 1), not IIII, so 1844 is MDCCCXLIV.

Wrong: MDCCCXXXXIIII

Why isn't 1844 written as MDCCCXXXXIIII?

No symbol can be repeated four times in a row, so XXXX and IIII are not used: 40 = XL, 4 = IV. Together they make MDCCCXLIV.
