Peculiar precedence

[cdecastro]

Thanks for the detailed comments. I appreciate the challenges in parsing such expressions, e.g. how is the parser to know whether ax is variable ax or the product of two variables a and x? Does it make any difference however when one of the expressions is a "constant". I gather the real issue is that this is a semantic issue that is ultimately unknown to the parser, i.e. the parser is only aware of syntax.

I am a high school mathematics teacher myself and wanted to share this experience in the interest of making work with the Prime more seemless. My only concern was that if the product is directed at an educational market, there might be some confusion from students who switch from one mode to another expect similar behavior. But, I will admit that we did not consult the documentation prior to this exploration, we were just surprised with the result. Thanks very much for the discussion and advice.

Appreciatively,
Chris
