Check MCMLXV by reading it back

Reading MCMLXV from left to right and adding the pieces: M = 1000, CM = 900, LX = 60, V = 5. Together that is 1000 + 900 + 60 + 5 = 1965, so MCMLXV and 1965 match.

Mistakes to avoid with MCMLXV

• Do not write the 4s and 9s additively. 1965 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 MCMLXV never contains forms such as VX or LC.
• Read MCMLXV as one number, not letter by letter: add the values left to right, except where a smaller symbol sits before a larger one.
