48
-----
2(9+3)
^because of the juxtaposition, the 2 is to be included/multiplied first by the 9+3, before it is divided like it would in regular pemdas.

I would know since I made this same thread a year or two ago.
That bring said, my answer is whatever kadyo's answer is.

I came up with 2.
The 2 being directly next to the parenthesis made me multiply whatever was in the parenthesis by 2.... And whatever that was would be divided.
Therefore 2 times ...9 + 3...... 2 times 12..... Which is 24
Back to the original
48 / 24 = 2

The answer is a resounding 288. If we follow the order of operations known as PEMDAS, we do the following: parenthesis, exponents, multiplication & division, addition & subtraction.
Parenthesis first
48/2(12)
Since multiplication and division are equally ranked, we then go left to right, per convention
24(12)
Then we finish it up
288.
Besides, I used my T-I83 Plus using the same notation and it cranked out 288. This is crazy, but I learned something today. Please, don't argue with my calculator's logic. It is sound and should be respected. It is the law of the land and it reigns supreme.Last edited by Null; 11-10-2012, 04:07 AM.

This is incorrect. This problem is not in fact an equation, it is a fraction. It should be treated like this:
48
--------
2(9+3)
or
48
----------
2 x 12
or
48
----
24
or
2
--
1
which of course is just 2.
