HAHAHAHHA come on NS! we all make fun of the "un-educated" on NSG yet some people are defending 288
Order of operations: PEMDAS
Parenthesis
Exponent
Multiplication/Division but multiplication comes first if possible
Addition/Subtraction but addition comes first if possible

1. (9+3)= 12 P
2. 2(12)= 24
3. 48/12= 2

2 you idiots

its 288 you moron, and i hadn't even heard about pemdas until some hours ago ....


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)

I'm sure i will never convince the 288 crowd, but for what its worth you can also use the distributive property and come up with the same (correct) answer

48/ 2 (9+3)

48/ (18+6)

48 / 24

2

In mine i made a typo but everyone knows what i meant.. I put 48/12=2 but i meant 48/24=2

Thankyou for being a logical math student

I wonder if you explain to your math prof that you made a "typo" that he would understand and still give you marks. My guess is no...

You idiot. one incredibly pointless thread wasnt enough? you had to make another on the same subject.

WOW

and multiplication & addition does not come first, you work left to right, just like you read. but who are we really kidding here, you probably don't do that very well either, do you sport?

funny story

today in math class my friend and i both entered it into our calculators the same way. different calculators though

anyways his got 2, mine got 288

so i have really no idea how this works

if you distribute it, you must distribute everything

after all it's: a (b+c) = (ab) + (ac)
so you must distribute 48/2....
a = (48/2)
b=9
c=3

a(b+c)
= ab + ac
=((48/2)*9) + ((48/2)*3)
=(24*9) + (24*3 )
=216 + 72
= 288

its not 48/(2(9+3))

Dude, please learn the order of operations:

Subtraction
Multiplication
Division
Addition
Addition again
Possibly exponents, but we'll wait a little bit
Multiplication
Parenthesis
Pi
Exponents

The answer is Pi, judging by step 9.

Well 1=2

  • Step 1: Let a=b.
  • Step 2: Then [IMG]math.toronto.edu/mathnet/falseProofs/fallacies_hlimgs/image1.gif[/IMG],
  • Step 3: [IMG]math.toronto.edu/mathnet/falseProofs/fallacies_hlimgs/image2.gif[/IMG],
  • Step 4: [IMG]math.toronto.edu/mathnet/falseProofs/fallacies_hlimgs/image3.gif[/IMG],
  • Step 5: [IMG]math.toronto.edu/mathnet/falseProofs/fallacies_hlimgs/image4.gif[/IMG],
  • Step 6: and [IMG]math.toronto.edu/mathnet/falseProofs/fallacies_hlimgs/image5.gif[/IMG].

  • Step 7: This can be written as [IMG]math.toronto.edu/mathnet/falseProofs/fallacies_hlimgs/image6.gif[/IMG],
  • Step 8: and cancelling the [IMG]math.toronto.edu/mathnet/falseProofs/fallacies_hlimgs/image7.gif[/IMG] from both sides gives 1=2.

If you knew anything about math you would know that multiplication and division as well as addition & subtraction are the same thing therefore neither can have precedent over the other.

say I want to divid by two

4/2= 2

but if I was doing it inside an equation like so by your rules I could jump a step up and just multiply by 1/2

4*(1/2) = 2

same goes for

4-2 = 2

4+(-2) = 2

http://www.purplemath.com/modules/orderops.htm

why don't you check out the second paragraph there chief.

Thank you for playing.

okay, so they come out to the final equation of:

2(a^2-ab)=1(a^2-ab)

then they fuck up.

they are then saying

a^2-ab = 1, for them to get 2=1

try solving a^2-ab=1, there are no real numbers that work.

it's like saying there is an equation x=2, now I'm subbing in x=3
oh no! 2=3!! what are we to do!

if you work it out,

a=0

and it works juuust fine

you should just write it down:

48/2*(9+3) is written down as:

48(9+3)
--------
2

Which makes:
576
--- = 288
2

love how people dont know the order of operations. multiply and divide are interchangable. work from left to right. you get 288. jesus.

so do you divide first or multiply first. the calculator always goes left to right in the case that multi[plication and division are together i think. i could be wrong but i think multiplication is first. so i go with my first answer


48/2(9+3)
48/2(12)
48/24
2

or

48/2(9+3)
48/2(12)
24(12)
288

48/2(9+3)=x
48/2(12)=x
48/2*12/12=x/12      -divide both sides by twelve to get rid of the twelve
48/2=x/12
576=2x      -cross multiplication
x=288
wolphram alpha agrees

the first one is definitely right but you should invest in a new calculator if it says 50-26= -26
