41 in Roman Numerals
Forty-one is written XLI in Roman numerals. It uses the subtractive rule, where a smaller glyph placed before a larger one is taken away rather than added, which keeps the numeral short and is the part most people find fiddly.
How XLI is formed
Reading left to right, 41 breaks into these additive parts. Each Roman symbol is added in turn to reach the total.
XL + I = 40 + 1 = 41.

Frequently asked questions
How do you write 41 in Roman numerals?
Write 41 as XLI, combining XL + I. Start from the largest value that fits and work down until nothing is left over.
Why is 41 not written XXXXI?
XLI uses the subtractive rule: a smaller symbol placed before a larger one is taken away, so you never repeat a symbol four times. XXXXI breaks that rule, which is why XLI is the only correct form.
Which Super Bowl is XLI?
Super Bowl XLI is the 41st Super Bowl, played in 2007. The NFL sets its championship number in Roman numerals, which is why so many people look up values like XLI.
What number is XLI?
XLI is 41. Read the symbols left to right, treat any smaller-before-larger pair as a single subtraction, and add the groups together.
