MMCDXXIV is written one place at a time, from the largest to the smallest: MM (2000) + CD (400) + XX (20) + IV (4) = 2424.
CD and IV are subtractive pairs: in each one the smaller symbol comes first and is taken away.
Common mistakes
Wrong: MMCCCCXXIV
Why isn't 2424 written as MMCCCCXXIV?
A symbol can't be repeated four times in a row. 400 is CD (500 − 100), not CCCC, so 2424 is MMCDXXIV.
Wrong: MMCDXXIIII
Why isn't 2424 written as MMCDXXIIII?
A symbol can't be repeated four times in a row. 4 is IV (5 − 1), not IIII, so 2424 is MMCDXXIV.
Wrong: MMCCCCXXIIII
Why isn't 2424 written as MMCCCCXXIIII?
No symbol can be repeated four times in a row, so CCCC and IIII are not used: 400 = CD, 4 = IV. Together they make MMCDXXIV.
