If they're the two operands to do in a sum, then you just work from left to right. To get the answer 2, you'd have to force the multiplication first and do 48/(2(9+3)). And calculators that have a stack i.e. graphic calculators will give the result 288. Other calculators without a stack will give the answer 2. I gave an example of it a couple of pages back.

No disrespect intended Everlong, but the rule, in PEMDAS, is not multipication first, multipication and division are equal in status. What you do is simply start from the left and go to the right.

Microsoft Math bears this out, as does Professor M. at CSU. If you still don't believe it you must be using a Mac. Attached Images My System Specs
