Mistakes to avoid with MCMLXIII

• Do not write the 4s and 9s additively. 1963 uses subtractive pairs (CM for 900), not strings like IIII or VIIII.
• Never repeat a symbol more than three times in a row. When a fourth would be needed, the subtractive form takes over.
• Only I, X and C may be placed before a larger symbol to subtract, so MCMLXIII never contains forms such as VX or LC.
• Read MCMLXIII as one number, not letter by letter: add the values left to right, except where a smaller symbol sits before a larger one.
