its 48/2(9+3) . which makes it 24(12) .. If its 48/(2(9+3)) it is indeed 2 ...
.. lol. someone give me an A+ or an F lol!!

you basically restated what i said. therefore we both get A's lol
It's 288. You multiply by what's in the parenthesis so
48÷2(9+3) = 24(9+3) = 24x12 = 288
48÷2(9+3) = 24(9+3) = 24x12 = 288
Interesting... Well everyone here gets it I wonder why it is really even a post anywhere, this is 3rd grade math at best. But hey its nice to know everyone here is intelligent at least.
Not so obvious to some people..here is a 100 page thread with 50/50 split
48÷2(9+3) = ???? - Bodybuilding.com Forums
I kinda see the point of people who voted 2
Like
a/bx... no one reads that as a/b*x although according to the left to right rule, it should be read that way.

'bx' equals b and x multiplied. So again, the parentheses are actually still there. Just invisible.
It's just another way of expressing it

The answer is 288. Rules of Order in algebra; 1) work the parentheses first 2) work multipication and/or division as it appears Left to right.
48÷2(9+3) = 24*12=288
48÷2(9+3) = 24*12=288
288
Type it into any spreadsheet (you'll probably have to enter it as =48/2*(9+3) -- the = sign tells the program it's not text, and leaving out the * between the 2 and the ( is just mathematicians' shorthand/sloppiness).
If you want something actually odd, try this:
a = b
multiply both sides by a
a^2 = a*b
subtract b^2 from both sides
a^2-b^2 = a*b-b^2
apply the distributive law to both sides
(a+b)(a-b) = b(a-b)
divide both sides by (a-b)
(a+b) = b
substitute all a's for b's (remember, if a = b you can do this)
a+a = a
regroup the two a's in the left side, and rename it 2a
2a = a
divide both sides by a
2 = 1

Technovapir has correctly stated the Rules of Order (that apply to this equation) of Algebra and it's solution.
Please, let us prove that nicotine addicts are smarter than steroid addicts, let's not make this an 89 page debate on which answer is correct. The correct answer of 288 has been given and the rule to get that answer.
Brackets and parenthesis first then MDAS is the key. Multiply Divide Add Subtract (the parenthesis gets simplified first)
48 / 2(9+3)=
48 / (2*9 + 2*3)=48/24=2
The 2 is part of the distributive property of the expression. 2(x+y) = 2x+2y. You can't operate with the 2 until the parenthesis is simplified.
It's 2.
