The seven Roman symbols
Subtractive rule. A smaller symbol before a larger one means subtract: IV = 4, IX = 9, XL = 40, XC = 90, CD = 400, CM = 900. You can only subtract I from V or X; X from L or C; C from D or M.
Maximum. Standard Roman numerals top out at 3,999 (MMMCMXCIX). Anything beyond needed a bar over the letter (vinculum) to multiply by 1,000.
