Check MCMLXXIV by reading it back

Reading MCMLXXIV from left to right and adding the pieces: M = 1000, CM = 900, LXX = 70, IV = 4. Together that is 1000 + 900 + 70 + 4 = 1974, so MCMLXXIV and 1974 match.

Mistakes to avoid with MCMLXXIV

• Do not write the 4s and 9s additively. 1974 uses subtractive pairs (CM for 900, 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 MCMLXXIV never contains forms such as VX or LC.
• Read MCMLXXIV as one number, not letter by letter: add the values left to right, except where a smaller symbol sits before a larger one.
