If I remember my history right, the order that math was done often depended
on the model of calculator it was done on.  I remember being warned as late
as 1991 how some calculators may still still add before they multiply, and
to use those parenthesis for good measure, just to be safe.

I know where there used to be a basic model slide rule that spans about 10
feet, it was mounted on the wall of the math room where I spent junior high.
My dad actually taught me basic arithemetic on it.  (Ironically, on the
opposite wall were the computers, an Apple IIe, a Commodore 64, two
TI99/4a's and about 4 Tandy 1000/tx's, this did all take place before 1989)
