Gary, that worries me a lot more than using "minus" in the
way that Barbara had described earlier. I don't know if it is
better to ban students' use of "minus" in that way or not;
at least it doesn't lead to conceptual errors, and it is clear
what the student means. But I know I would least tell the student
that this usage is nonstandard; that I believe he should know.
