And that is just ridiculous!

If he responds later on today, I'll post his reply.

I am not following how it's ridiculous.

Here is a prof at DePaul University with a background in Math.

The answer is 2....the parens does have to be worked first, therefore it is 48/24....it's that simple....you 288 guys arent reading it right....forty eight divided by two times nine plus three....that is how it is meant to be read.....suck it

You are wrong sir, the way you are reading it, the 48/2 should also be in parens, but it isn't, therefore the correct simplification of the problem is 48/24....simple as that...

everyone involved needs to enjoy this

Otherwise just go left to right. Example:
yes 30 ÷ 5 × 3 = 6 × 3 =
18

no 30 ÷ 5 × 3 = 30 ÷ 15 =
2
(wrong)
How Do I Remember It All ... ? PEMDAS !

P
Parentheses first
E
Exponents (ie Powers and Square Roots, etc.)
MD
Multiplication and Division (left-to-right)
AS
Addition and Subtraction (left-to-right)

i agree with you, but one could just as easily say it should be 48/(2x(3+9) as they could say (48/2)(3+9).

i still say it's 2. the 2 in the problem is an essential part of the parentheses part of the equation.

Ok let me try this.

48÷2(9+3) = The missing Longoria Super Refractor
See now was that really that hard. Ok next problem

The problem isn't the order of mult or division per se, but rather the fact that the multiplication BESIDE the parentheses exists.

If it was a simple equation like the one in the above quote there would be no debate.

Parenthese first you are right, which means Completely get rid of the Parenthese, and the only way to do that is to multiply the 2.....basic math!!!!

[gracecollector]

This equation was dreamed up by Topps for its Canadian sweepstakes/redemption question. 1/2 (that's 1 divided by 2, or 50%) will never get their cards = another way to screw collectors!

 

[Pine Tar]

Ok never mind I was wrong the first time

[bballcardkid]

It's a lot easier to visualize the problem like this:

48
___________________

2 * (9+3)


You can chop this problem into two parts:

48
____

2

and

1
_____ which is 1/12

(9+3)

People who are saying 288 are forgetting that the value is 1/(9+3), not (9+3) itself. Pemdas is being obeyed, but the wrong numbers are being used. To finalize:

48 * 1
________ = 48/24 = 2
2 * 12

this pretty much tells you all you need to know.

if you believe in implied multiplication, as many of us do, then it is 2. if you believe in sticking strictly to PEMDAS then it is 288.

ultimately, no self respecting math teacher would ever ask this problem to be answered in seriousness as it is lacking a set of parentheses.

IF you are following the order of operations the way it is intended to be followed the answer is 288. People always think that because multiplication comes before division in "PEMDAS" that multiplication always comes before division. In reality, multiplication and division are TIED in terms of which operation is more important to do next. If both occur within the same expression you are supposed to do them in left-to-right order to break the tie. I teach my 5th graders this every year.

Ok now do these

Thanks. :lol:

I can see why someone would multiply the two times the contents of the parentheses before dividing, and I hate problems that are like this. I don't give my students problems like this one because that would be pushing it at their age.
