One set of calculators assumes parentheses with 48/2(9+3), even Google's calculator as well as the Wolfram calculator assume a set of parentheses around 48/2 when doing their calculations. Either way, any person with a brain should be using parentheses around the desired components when doing the calculations. When somebody just types that into a calculator, it has to assume one way or the other. How are you supposed to know whether or not a person is asking 48/(2(9+3)) or (48/2)(9+3) if you don't separate the equation properly?
