48÷2(9+3)

This is from some bc teachers website

[Nightwalker]

That's how I was taught.

[PiuYi]

can someone PM me when this thing is settled and we have a definite answer? thanks.

i cant believe this has spawned 7 pages... jesus

Cool, good job finding that.

Ignoring the fact that this was a poorly written equation, when an equation is written as:

2(x+y)

I'd usually read the equation as (2x+2y) and this whole thing would be "brackets" for you bedmas lovers.

So 48/2(9+3) = 48/(18+6) = 48/(24) = 2

To me, it seems that to arrive at the answer of 288, the equation would have to look like this to me: (48/2) x (9+3).

It really depends on how you see this equation in your head.

48÷2(9+3) = No one cares. Let's move on.

Zenza explained it right. Answer is 2

Just to make sure, I actually e-mailed one of my math professors today (disclaimer, this is a prof that knows me quite well, so no... i'm not an idiot):

I hope your exam on the 27th will not be as hard as this fucking equation that spawned 7 pages of debate.

Heres how i see it

Now I am not actually sure if you are serious or not, maybe you are just a bit too
stressed with exams and stuff coming up and you are in need of a joke. Oh well It's always fun to go back to the basics.

LOLOL

[johny]

let 9 = x and y = 3

48/2(x+y) = 24(x+Y) = (24x + 24y) = 288

or 48/2(x+y) = 48 / (2x+2y) = 48/ (18+6) = 2

needs more brackets...

my Ti 83 says 288...

[Razor Ramon HG]

Hmm, the more I read up on this, the more convinced I am that it's 288 and not 2.

[xilley]

for real? its 288

technically, all that work is an example of 48 / (2(9+3)), if you're dividing all of 2(9+3) by 48.

apprently americans go by something called PEMDAS.....anyone here recieved an american education care to explain?

No one liked my natural log approach? It suggests 288 though...

48/2(9+3)

ln(48)-ln(2)+ln(9+3) = ln(288)

So yes, 288 is the correct answer.

However, I still think it's bad form and I would say 2 is the correct answer if I didn't take the natural log.

It's the same shit, Parentheses = Brackets

there's no difference... pemdas bedmas etc etc etc its just a mnemonic

here

Mnemonics are often used to help students remember the rules, but the rules taught by the use of acronyms can be misleading. In Canada the acronym BEDMAS is common. It stands for Brackets, Exponents, Division, Multiplication, Addition, Subtraction. In other English speaking countries, Brackets may be called Parentheses, or symbols of inclusion and Exponentiation may be called either Indices, Powers or Orders, and since multiplication and division are of equal precedence, M and D are often interchanged, leading to such acronyms as BIMDAS, BODMAS, BOMDAS, BERDMAS, PERDMAS, PEMDAS, and BPODMAS.

These mnemonics may be misleading, especially if the user is not aware that multiplication and division are of equal precedence, as are addition and subtraction. Using any of the above rules in the order "addition first, subtraction afterward" would also give the wrong answer.

10 - 3 + 2 \,

The correct answer is 9, which is best understood by thinking of the problem as the sum of positive ten, negative three, and positive two.

10 + (-3) + 2 \,

There is a new mnemonic featured in Danica McKellar's books Math Doesn't Suck[2] and Kiss My Math[3] that does address this very issue: "Pandas Eat: Mustard on Dumplings, and Apples with Spice." The intention being that Mustard and Dumplings is a "dinner course" and that Apples and Spice is a "dessert course." Then it becomes not a linear string of operations to do one after the other, but rather the "dinner course" operations are considered together and performed left to right, and then addition and subtraction are considered together, again performed again left to right.

http://en.wikipedia.org/wiki/Order_of_operations

http://www.mathgoodies.com/lessons/v...perations.html

http://www.mathgoodies.com/lessons/v...exponents.html

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)

Divide and Multiply rank equally (and go left to right).

Add and Subtract rank equally (and go left to right)



After you have done "P" and "E", just go from left to right doing any "M" or "D" as you find them.

Then go from left to right doing any "A" or "S" as you find them.

Note: in the UK they say BODMAS (Brackets,Orders,Divide,Multiply,Add,Subtract), and in Canada they say BEDMAS (Brackets,Exponents,Divide,Multiply,Add,Subtract). It all means the same thing! It doesn't really matter how you remember it, just so long as you get it right.

This equation has become a fucking meme

to all the stupid people in the world for entertaining the rest of us

[MG1]

parenthesis = ( )
brackets = [ ]
braces = { }
angle brackets = < >

just splitting hairs
