you could outprogram me in a heartbeat (although my BSc was a joint honours with Computer Science) ...it just won't get you anywhere in math if the main hits on a google search are too simplistic.

A. http://blogs.edweek.org/teachers/coa...--forever.html
B. http://www.angrymath.com/2009/03/pem...prejudice.html C. I blame whoever wrote the equation, because it begs for misinterpretation. Extra parentheses for clarification are never wrong. D. Why the hell did I open a math thread started by Flint? It's always trouble. |

It needs more brackets to be two.

Excel says...
288 I tried it four times. Maybe they do it different in the old country. |

288.
In spite of MDAS, Multiplication and Division are equal in precedence. Evaluation proceeds from left to right. The use of the 2(..) notation for multiplication is tempting you to treat 2(9+3) as a single unit. 48 / 2 x (9+3), with the multiplication sign written out, seems less ambiguous (though I don't think it is). Again, it's a screwy example. |

I want to add something to my answer. I've been thinking about it (while cleaning my office - not like I'm obsessing or anything).
My "gut feeling" with this answer was to say it was 2, because of the way it's written. Sometimes I've found on tests you have to figure out what they want for an answer, which may not be what is technically correct. Which of course implies that math may not be as black-and-white as you'd think, that problems are open to interpretation, which is kind of weird, but anyway. I think that if the intention were to get 288 as an answer, the question would have been written: (48÷2)(9+3) = ??? But because it lacked that one set of brackets, the author of the question wanted us to multiply 9+3 by 2 before dividing 48 by something. I've always felt that a number right next to a bracket implied a sense of urgency. But I still think the correct answer is 288. And if you read this and rolled your eyes, you have a deeper understanding of why I am an English major. |

Let's Lynch Flint!
see? That'll fix everything. Besides, Flint is crazy.
