  • Do not write the 4s and 9s additively. 1993 uses subtractive pairs (CM for 900, XC for 90), not strings like IIII or VIIII.

  • Only I, X and C may be placed before a larger symbol to subtract, so MCMXCIII never contains forms such as VX or LC.
  • Read MCMXCIII as one number, not letter by letter: add the values left to right, except where a smaller symbol sits before a larger one.
