I had the same question John had when I read Steve's initial post. But, even then why would "/" indiate the grouping of (4)(8) but not (4)(8) + 4? Is that because we have parentheses around 4 and 8? Of course, if "/" meant the fraction bar, we wouldn't have this confusion if we write the fraction without using "/". There won't be any question of grouping if it was written
64 _______ (4)(8).
By the way, if you enter 64/(4)(8) + 4 to TI83 as it appears, you get 132, and calculators are always correct, right? :)
