Check LXIX by reading it back

Reading LXIX from left to right and adding the pieces: LX = 60, IX = 9. Together that is 60 + 9 = 69, so LXIX and 69 match.

Mistakes to avoid with LXIX

  • Do not write the 4s and 9s additively. 69 uses subtractive pairs (IX for 9), 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 LXIX never contains forms such as VX or LC.
  • Read LXIX as one number, not letter by letter: add the values left to right, except where a smaller symbol sits before a larger one.
