Very good. You should continue to repeat those kinds of logical affirmations into the mirror whenever your grasp on reality becomes tenuous.
Wait wait. Are you one of the dumb ones? If you think the answer is 288 I feel sorry for you too. I like this thread tho because it gives me an idea of how stupid most people are in general.
1. Wrong.
2. Has always been the case. It was programmed by a human. I remember when people would say "it must be true, it's in a book".
Mistakes are found throughout some math text books as well.Nah. Most calculators don't understand Simplification, some do. Any number before the Parentheses has to be Simplified with it. The hard heads can dispute it all they want, but it is what it is.
This is a perfect example of why it's WRONG. notice in the first picture it's dividing 48 by 2 first, which is wrong Immediately. You start with the parenthesis
10(7)
----
5
WOULD BE (10*7)/5 OR (10(3+4))/5 NOT 10/5(10-3)
for this equation the answer is 10/35. 10/5(10-3) is not (10/5)(10-3). WE CANT ALL USE PEMDAS AND GET BOTH ANSWERS
ANOTHER PROOF ACCORDING TO http://www.mathwithlarry.com/lessons/lesson053.htm
A student submitted some questions on this topic. The first one is: 6 + 3(7 - 2). First we must always do what is in parentheses. Don't even look at anything else yet. We now have 6 + 3(5). Sometimes in math, when we multiply, we leave out the x symbol. This is because later we'll actually use x for a different purpose, and we don't want to get confused. What we really have here is 6 plus 3 times 5. After multiplying 3 times 5, the problem is now 6 + 15. Now we just add to get 21.
I know it is an "addition" problem but the parentheses doesnt go away after you add the 9+3. the parentheses is still there! (12) it has to be resolved so you have to multiply the 2 THEN divide 48 by that answer.
you guys are incorrectly stating the () disappears once 9+3=12, it does not.

If Jesus came back and told your dumb ass that the answer was 2, you wouldn't believe him. Only way to get hard headed fucks like you to realize something involves you staring down a barrel of a loaded gun.
its still the same essentially because after you do whats in the parentheses, you go to the left and solve the division and then multiply
48÷2(9+3)
48÷2(12) P
48÷2(12) E (No exponents)
24(12)=288 M or D (Division comes first when looking left to right so we divide than multiply)
No A or S
1/2($5.00) - $2.00. the 1/2 belongs to the ($5.00) because it is next to it. under your earlier justification 1/2 * $5.00 then - $2.00 while it does give you the right answer it is incorrect. ex.
1/2($10.00-$5.00) - $2.00 should give you the same answer, under your system it does not.
Also 1/2 is not how the equation is written. 1/2($5.00) is not the same as 1 divided by 2($5.00)

I may be mistaken, but I think cbm_redux is atheist.
In the 1st picture its "grouping" the multiplication AND division from left to right AFTER the parentheses (9+3) is SOLVED. The 2nd picture is doing to exact same thing. Please show me an answer of 2 on a calculator to disprove.

SIMPLIFICATION
You solve the Parentheses, and multiply the number in front before you do anything!
This is where much of the confusion begins (outside of the fact the equation is poorly written). To help eliminate the parenthesis and proceed with solving the remainder of the equation we can use distributive property:
=2(9+3)
=2(9) + 2(3)
=18+6
=24
OR
=2(9+3)
=2(12)
=24
Now we proceed to step two of solving the equation:
48/24
=2
Just like 48 divided by 2 is 24, 24 times 12 is 288
Yep, the answer is 288. If that was the equation. But that's not the one in the OP, mongoloid...

I don't give a rat's ass about sweet white Jesus. Neither you nor he graduated summa cum laude. I did. More specifically, I was paying attention in grade 5 when grouping symbols where explained. Obviously, you were not. That's funny to me.
Now, if Sir Isaac Newton told me that I was wrong, well then I'd have to say, Sir Isaac, are you high?
it does give the same answer under our system
1 ÷ 2 * ($10-$5) - $2
=1 ÷ 2 * $5 - $2
= 0.5*$5-$2
=$2.5-2
=$0.5
this is 2 all day long. 
Only the 2 is under 48. 2 is not exclusive to (9+3) and (9+3) isnt under 48, it would need to be 48/(2(9+3))
the problem reads 48/2 times (9+3)
You can use Distributive property or PEMDAS to solve it
You still haven´t learned huh?
Yep ur an idiot
Exactly. Any number in front of a parenthesis takes priority over any other multiplication or division. It is part of the parenthetical equation...it is a FACTOR multiplied by PARENTHESES. not the same as multiplying 2 numbers
the parentheses and anything multiplied by it take priority. For those who can do it, replace the (9+3) by x and tell me the answer you get....I'll tell ya:48/2x. Simplify your fraction (cancel out a 2 in the numerator and denominator) and you get 24/x.....get it? Now put the "9+3" back in for x and you get 48/24....which equals 2....
It's been answered for you already, but I'll quote it again for those who don't get it. any number next to parentheses is a factor to be multiplied by everything inside of the parentheses:
2(9+3) = (18+6)
2(9+x) = (18+2x)
2(x+y) = (2x+2y)
You can not separate a factor multiplied by a parentheses.
it all depends where the parentheses are located. in this case it is located beneath the 48, next to a 2. you can divide 48 by 2 first, but the (9+3) is still in the denominator...24/(9+3)I've already damned the OP and this thread both to hell... but at the risk of having my diploma rescinded, i have just one question:
What is the point of computing what's inside the parentheses FIRST, if we don't then eliminate them altogether by computing the product of the number outside the parentheses and the sum of its contents?
The answer to this is 4. 24/[3*(4/2)]= 24/[3*(2)]= 24/6 = 4. or 24/[(3*4)/2)] = 24/(12/2)= 24/6 = 4. There is no rank order in this equation because multiplication and division carry the same weight....but a parenthesis and any factor multiplied by it always takes priority over multiplication & division of 2 numbers...
not true
False. The 2 is multiplied by the parentheses so THAT equation 2(9+3) takes priority over everything else happening in the equation...
Precisely. That's what I've said all along. According to the well established rules of arithmetic (not to be confused with the fencing manual, The Book of Arithmetic) the answer, 288, indisputable.
Its the same exact format 9+3 is 12
48/2(12)
are the same format
1/2(5)
it could of been 1/2(2+3)
which is the same as 1/2(5)
correct
it's so fun. sitting here watching TV and stating the same thing 20 different ways, hoping that the power of algebra will spread to those who did not learn it the first time around
This is hilarious coming from you considering your history on this board.
Especially, given what happenned the last you got out of line. Carry on.
