Roman Numerals 1-70

Need a number above 70? Use the converter.

The pattern

From 1 to 70 you only need 4 symbols: I (1), V (5), X (10), and L (50).
22 of the 70 numbers use subtraction: every number with a 4 or a 9 in one of its places, such as 4 (IV), 9 (IX), and 40 (XL).
Each number is its ten followed by its unit, read from left to right: 67 (LXVII) is LX + VII, and 44 (XLIV) is XL + IV.
The longest is 38, XXXVIII, with 7 letters.

Common mistakes

Wrong: IL

Why isn't 49 written IL?

Only I, X and C subtract, and only from the next two symbols (IV, IX, XL, XC, CD, CM). The correct form is XLIX: XL (40) + IX (9).

Wrong: ~~XXXX~~

Why isn't 40 written XXXX?

A symbol can repeat at most three times in a row. The correct form is XL: L − X.

Wrong: ~~IIX~~

Why isn't 8 written IIX?

Only one smaller symbol can come before a larger one. The correct form is VIII: V + I + I + I.
