It depends, is "-" minus, and "- -" division according to your blackboard
drawing top-down methodology? There is no "- -" listed on any math symbols list
sites I can find out there, so it must be something from the 60s-70s when
computers maybe couldn't do proper symbols?
Either way, and if I'm correct in my assumption, the first one would be 6, and
the second one would be -6, as division comes before subtraction in the order of
operations. Again, no need for parenthesis. If there were parenthesis, you would
do whatever was in those first.

There's nothing 'old school' about it. It's basic, simple math. Why do you
insist on adding parenthesis everywhere?
