Common mistakes
Wrong: MMMDCXXCVIII
Why isn't 3688 written as MMMDCXXCVIII?
Only one smaller symbol can stand before a larger one, so XXC doesn't work. 80 is LXXX (50 + 30), so 3688 is MMMDCLXXXVIII.
Wrong: MMMDCLXXXIIX
Why isn't 3688 written as MMMDCLXXXIIX?
Only one smaller symbol can stand before a larger one, so IIX doesn't work. 8 is VIII (5 + 3), so 3688 is MMMDCLXXXVIII.
