Frequently asked questions
How do you write 49 in Roman numerals?
Write 49 as XLIX, combining XL + IX. Start from the largest value that fits and work down until nothing is left over.
Why is 49 not written XLVIIII?
XLIX uses the subtractive rule: a smaller symbol placed before a larger one is taken away, so you never repeat a symbol four times. XLVIIII breaks that rule, which is why XLIX is the only correct form.
Which Super Bowl is XLIX?
Super Bowl XLIX is the 49th Super Bowl, played in 2015. The NFL sets its championship number in Roman numerals, which is why so many people look up values like XLIX.

48 is XLVIII and 50 is L. Neighbouring numbers often change length in surprising ways, which is why each has its own page.
