Your K-12 education was clearly better than mine...

I assume that by the dual operator "*", you mean "*" in a superscript position such as in x^*.  In such a position, it has no arguments and precedence is meaningless so I don't understand what you are asking/commenting on.  Maybe this exposes just how weak my K-12 education was :-)

FYI:  (as you know) "*" is not usually used for multiplication in typeset math -- &CenterDot; or &times; or &it; are typically used.  "*" was included for compatibility with ASCII-based math notations just as ">=" was included.  The operator dictionary does not recommend one form over another and tried to be inclusive as an aid to developers in case those notations were used by authors.
