749 in Roman Numerals = DCCXLIX
Seven hundred forty-nine is written DCCXLIX in Roman numerals. The subtractive rule works twice in DCCXLIX, in XL for 40 and IX for 9: a smaller glyph placed before a larger one is taken away rather than added, which keeps DCCXLIX shorter than stacking strokes would.
What is 749 in Roman numerals?
How DCCXLIX is formed
Reading left to right, 749 breaks into these additive parts. Each Roman symbol is added in turn to reach the total.
D + C + C + XL + IX = 500 + 100 + 100 + 40 + 9 = 749.
The shape of DCCXLIX
- Written out, DCCXLIX runs 7 characters, against 9 for 748 (DCCXLVIII) and 4 for 750 (DCCL).
- DCCXLIX works 2 subtractions at once, XL and IX, which is why it comes out shorter than a stroke-for-stroke spelling of 749 would.
- Every number from 700 to 799 opens with DCC, so it is the XLIX after DCC that marks 749 out as 49 past 700.
- DCCXLIX draws on 5 of the seven symbols, with C doing the most work at 2 appearances.

Frequently asked questions
How do you write 749 in Roman numerals?
Write 749 as DCCXLIX, combining D + C + C + XL + IX. Start from the largest value that fits and work down until nothing is left over.
Why is 749 not written DCCXLVIIII?
DCCXLIX uses the subtractive rule: a smaller symbol placed before a larger one is taken away, so you never repeat a symbol four times. DCCXLVIIII breaks that rule, which is why DCCXLIX is the only correct form.
What are 748 and 750 in Roman numerals?
748 is DCCXLVIII and 750 is DCCL. Neighbouring numbers often change length in surprising ways, which is why each has its own page.
How is DCCXLIX broken down?
DCCXLIX breaks down as D (500), C (100), C (100), XL (40), IX (9), so D + C + C + XL + IX = 500 + 100 + 100 + 40 + 9 = 749.
