OK, I must be missing something here.
Help me understand what's going on.
TeX typesets A^{-B + C} and A^{(-B + C)} as something resembling
-B + C
A
and
(-B + C)
A
respectively.
Aren't these two expressions equivalent?
What is an interpretation of A^{-B + C}, other than A^{(-B + C)} ??
Surely A^{-B + C} can't be interpreted as A^{-B} + C,
because that is rendered as
-B
A + C
and neither A^-B + C which is rendered as
-
A B + C
best,
