Common mistakes
Wrong: CXXCVIII
Why isn't 188 written as CXXCVIII?
Only one smaller symbol can stand before a larger one, so XXC doesn't work. 80 is LXXX (50 + 30), so 188 is CLXXXVIII.
Wrong: CLXXXIIX
Why isn't 188 written as CLXXXIIX?
Only one smaller symbol can stand before a larger one, so IIX doesn't work. 8 is VIII (5 + 3), so 188 is CLXXXVIII.
