The pattern
- From 1 to 90 you only need 5 symbols: I (1), V (5), X (10), L (50), and C (100).
- 27 of the 90 numbers use subtraction: every number with a 4 or a 9 in one of its places, such as 4 (IV), 9 (IX), 40 (XL), and 90 (XC).
- Each number is its ten followed by its unit, read from left to right: 87 (LXXXVII) is LXXX + VII, and 94 (XCIV) is XC + IV.
- The longest is 88, LXXXVIII, with 8 letters.
- New compared with the 1–80 list: the symbol C (100) and XC for 90 (C − X).

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: XXC
Why isn't 80 written XXC?
Only one smaller symbol can come before a larger one. The correct form is LXXX: L + X + X + X.

Common questions
Which numbers from 1 to 90 use subtraction?
27 of the 90: every number that has a 4 or a 9 in its units, tens or hundreds. The first ones are 4 (IV), 9 (IX), 14 (XIV), and 19 (XIX); the last one is 90 (XC).
What is the longest Roman numeral from 1 to 90?
LXXXVIII (88), with 8 letters.
Why is 90 written XC and not LXXXX?
LXXXX would repeat X four times, and a symbol can repeat at most three times in a row. Putting X before C means C − X = 90.
