How to write 2018 in Roman numerals, step by step
Roman numerals are built from largest value to smallest. Split 2018 into place values first: 2000 + 10 + 5 + 3.
Now swap each part for its symbols: 2000 becomes MM, 10 becomes X, 5 becomes V, 3 becomes III. Written together that is MMXVIII.
No subtraction is needed here, so the symbols are simply added in descending order.
- 2000 = MM (M is 1000, written 2 times)
- 10 = X (X is 10)
- 5 = V (V is 5)
- 3 = III (I is 1, written 3 times)
Is MMXVIII written correctly?
Yes. MMXVIII is the standard modern form of 2018. A valid Roman numeral never repeats a symbol more than three times in a row, never repeats V, L or D at all, and only ever subtracts I, X or C, and only from the next two larger symbols.
Those rules are what keeps a number to a single accepted spelling, so a reader never has to guess.
How to type MMXVIII on a keyboard
Roman numerals are ordinary capital letters, so you can type MMXVIII directly: M, M, X, V, I, I, I. Nothing special is required and it will work in any font, any document and any web form.
Unicode also contains dedicated Roman numeral characters such as Ⅰ, Ⅴ, Ⅹ, Ⅼ, Ⅽ, Ⅾ and Ⅿ. They exist for typesetting East Asian text and they look almost identical, but search engines, spell checkers and screen readers handle the plain letters better, so the letters are usually the right choice.
Using 2018 as a date
Written as a full date, 2018 usually appears at the end: 4 July 2018 becomes IV • VII • MMXVIII, with dots or dashes separating day, month and year.
If you are having MMXVIII engraved or tattooed, check the spacing and the character shapes with the artist first. Roman numerals are long, and MMXVIII is 7 characters, so it needs more room than the four digits do.
