'1'+'2' is pretty meaningless. In the other cases you're giving a type
that has a meaningful + operator so it's trying to convert the quoted
argument to an appropriate type for +. In the '1'+'2' case it's
converting to "char" (single character) and adding those which seems
marginally reasonable to me (although I think that "char" is pretty
silly).
I'm not sure what you expected '1'+'2' to give though, concatenation is ||
and I can't think of something meaningful to do with it.
