Common mistakes
Wrong: MCCMXVIII
Why isn't 1818 written as MCCMXVIII?
Only one smaller symbol can stand before a larger one, so CCM doesn't work. 800 is DCCC (500 + 300), so 1818 is MDCCCXVIII.
Wrong: MDCCCXIIX
Why isn't 1818 written as MDCCCXIIX?
Only one smaller symbol can stand before a larger one, so IIX doesn't work. 8 is VIII (5 + 3), so 1818 is MDCCCXVIII.
