How 41 is written

41 is the sum of its place values, 40 + 1, and is written forty-one.

Its ordinal form is forty-first — only the final element takes the ordinal ending — and on a check the amount line reads "Forty-one and 00/100", where 00/100 stands for zero cents.

The hyphen in forty-one is required: English hyphenates every compound number from twenty-one to ninety-nine.

Its Roman numeral XLI uses subtractive notation: XL means 40, written as X before L instead of repeating X.
