@code{minus}, the @code{neg} operations (if any) will be moved inside
the operations as far as possible. For instance,
@code{(neg (mult A B))} is canonicalized as @code{(mult (neg A) B)}, but
-@code{(plus (mult (neg A) B) C)} is canonicalized as
+@code{(plus (mult (neg B) C) A)} is canonicalized as
@code{(minus A (mult B C))}.
