Common mistakes
Wrong: MMDCXXCVIII
Why isn't 2688 written as MMDCXXCVIII?
Only one smaller symbol can stand before a larger one, so XXC doesn't work. 80 is LXXX (50 + 30), so 2688 is MMDCLXXXVIII.
Wrong: MMDCLXXXIIX
Why isn't 2688 written as MMDCLXXXIIX?
Only one smaller symbol can stand before a larger one, so IIX doesn't work. 8 is VIII (5 + 3), so 2688 is MMDCLXXXVIII.
