MDXLIV is written one place at a time, from the largest to the smallest: M (1000) + D (500) + XL (40) + IV (4) = 1544.

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

Common mistakes

Wrong: MDXXXXIV

Why isn't 1544 written as MDXXXXIV?

A symbol can't be repeated four times in a row. 40 is XL (50 − 10), not XXXX, so 1544 is MDXLIV.

Wrong: MDXLIIII

Why isn't 1544 written as MDXLIIII?

A symbol can't be repeated four times in a row. 4 is IV (5 − 1), not IIII, so 1544 is MDXLIV.

Wrong: MDXXXXIIII

Why isn't 1544 written as MDXXXXIIII?

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