Check XXXIV by reading it back

Reading XXXIV from left to right and adding the pieces: XXX = 30, IV = 4. Together that is 30 + 4 = 34, so XXXIV and 34 match.

Mistakes to avoid with XXXIV

  • Do not write the 4s and 9s additively. 34 uses subtractive pairs (IV for 4), 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 XXXIV never contains forms such as VX or LC.
  • Read XXXIV as one number, not letter by letter: add the values left to right, except where a smaller symbol sits before a larger one.
