Hello, 

I am just interesting how it should work?

That is still written in the user interface help:
------------------
"You can enter any valid mathematical expression 
and you can reuse the "x" variable as many times 
as you need to ..."  
... 
"even a UPS weight based calculation"
...
"It is important to note that you must specify some 
sort of equality on the left hand side of the equation."

In program: Interpolate.pm
-------------------------------------------------
                        return '' if $final == 0;
                        $o->{adder} =~ s/\bx\b/$final/g;
                        $o->{adder} =~ s/\@\@TOTAL\@\\?\@/$final/g;
                        $o->{adder} = $ready_safe->reval($o->{adder});
                        $final += $o->{adder} if $o->{adder};
                        $final = POSIX::ceil($final) if
is_yes($o->{round});
--------------------------------------------------
i.e. you can use any valid mathematical expression, 
but without left hand side of the equation.

Sorry, if I miss something.
