P in Pemdas doesn't mean to use the parentheses but rather solve whats inside. Plug it into a Scientific Calculator. The automatically follow pemdas. Lol at people who swear its 2. Go back to school son  | ||

If you just say the problem out loud, it makes sense: 48/2(9+3)=Fourty-eight divided by two multiplied(or distributed to) by nine plus three. Order of operations tells you to SIMPLIFY what is in parentheses first. Once it is fully simplified(12), you remove the parentheses and multiply by the base. In this case, the base is 48/2, which is 24. As such, you multiply your base, 24, by what was in the parentheses, which is now 12. 24x12=288. Granted it's already explained by lots of people above, hopefully this will help someone who doesn't get it yet, understand. | ||

It should be written (in LaTex, or similar): \frac{48}{2(9+3)} or \frac{48}{2}(9+3) The fact that the two is left outside the brackets, but without an explicit multiplication symbol leaves the question as to which one the author meant it to be. Didn't vote either, the question is deliberately misleading. | ||

http://www.wolframalpha.com/input/?i=48/2(9+3) There is no argument in this question. Anyone saying it's 2 is a troll or has made an honest mistake. | ||

I would argue that the more math you do the more likely you are going to get this wrong. Entirely because of the fact that nobody who actually does math would ever write an equation in this way. | ||

for that exact reason. If you multiplicate without even using a multiplication sign, its stronger than dividing. a/bcde = a/(bcde), not acde/b This captured everything I wanted to say. From personal experience in many math classes, attaching a parenthesis to something without explicit use of a multiplication symbol joins the two statements together. That, however, isn't algebraically correct. I stand by the reasoning though. | ||
