Check MCMXLVII by reading it back
Reading MCMXLVII from left to right and adding the pieces: M = 1000, CM = 900, XL = 40, VII = 7. Together that is 1000 + 900 + 40 + 7 = 1947, so MCMXLVII and 1947 match.
Mistakes to avoid with MCMXLVII
- Do not write the 4s and 9s additively. 1947 uses subtractive pairs (
CMfor 900,XLfor 40), 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 MCMXLVII never contains forms such as VX or LC.
- Read MCMXLVII as one number, not letter by letter: add the values left to right, except where a smaller symbol sits before a larger one.
