How to write 39 in Roman numerals

Break 39 into thousands, hundreds, tens and ones, then write each part with the largest symbols first:

• 30 (tens) = XXX
• 9 (ones) = IX

Join them: XXXIX.

XXXIX uses the subtraction rule in IX: a smaller symbol placed before a larger one is taken away from it, so IX = 9. Only I, X and C are used this way.
