Post by: memo3300 on April 13, 2011, 08:23:50 PM: Since what i know it should be 288 because you read the problem from left to right.

so you have to do first 48/2... no 2 x 12

In order to solve a question with multiple operations (add/subtract, multiply/divide) there is an order to follow often referred to as 'BEDMAS'
BEDMAS is an acronym that stands for;

B-brackets
E-exponents
DM-multiply or divide (left to right)
AS-add subtract (left to right)

The order of math in which you solve a mathematical problem.

Parenthesis, Exponents, Multiplication, Division, Addition, and Subtraction

same with add and subtract.

Technically, when you had 48/2(12) wouldn't it multiply to 24 because of parenthesis? So then 48/24=2
Title: Re: Let the flame war begin
Post by: Alex Mason, SOG on April 14, 2011, 06:42:55 PM: YEAHno

P E MD AS

There aren't any variables and you can do the operation inside the parenthesis.
Also, The distributive property is a property of multiplication

EDIT:

No, because 48/2(12) is the same as 48/2*12.
It's multiplication.

Post by: Xrain on April 14, 2011, 08:13:34 PM: For the OP:
(http://img.photobucket.com/albums/v514/xrain/Problemsolved.jpg)

That is how you solve it, the only way you can get 288 as an answer is if you failed at order of operations, and divide 42 by 2 to get 24, then do the parenthesis, and multiply 24 by 12.
But that is an incorrect way to solve the problem.

Since you all ignored my challenge of a Triple Integration

This is how I learnt

e.g.
[(9000 * 9000)9000]

[((3.14 * 3.14)3.14)3.14]

so brackets go on the outside just to make it look neater.
I don't know why I said what I did in the last post I must have been thinking of something else.

Also would anyone happen to know the keyboard shortcut for exponents?

But... Now your failing at order of operations. Multiply and divide have the same "priority", so when you have both it goes left to right.

48/2(9+3)
48/2(12) Parenthesis first!
24(12) Left to right! (48/2)
288 Last step!

Not quite, your making several algebra mistakes.

first you cannot divide items in the denominator separately

(http://img.photobucket.com/albums/v514/xrain/Algebra-1.png)

But you are correct, multiplication and division have the same priority.

However, it's not order of operations that prevents you from doing this, its the basic rules of algebra that prevents you from calculating it like that.

Unless of course the OP wrote the equation ambiguously intentionally, using a little loop hole in standard equation writing.

48÷2(9+3) Generally means 48/(2*(9+3))

48÷2*(9+3) Can mean

48/(2*(9+3))
or
(48/2)*(9*3)

If that is the case, then it's just a failure on the OP's part to properly define an equation.

If he did intentionally write it that way, He is going to end up banned because stuff like that pisses me off O:-)

If you want something to really mess with your brain, try this on for size.

a=b
ab=b²
ab-a²=b²-a²
a(b-a)=(b+a)(b-a)
a=b+a
a=a+a
1=2

Aha! the key is you don't factor at all, just divide both sides by (b-a)

a(b-a)=(a+b)(b-a)

a(b-a)/(b-a)=((a+b)(b-a))/(b-a)

a=a+b

Don't get me wrong there is something horribly wrong with that proof, I'm just curious to see if you can find it. ;D
Title: Re: Let the flame war begin

lets start replacing variables.

a=b kgood
ab=b² aa=a² 0=0
a²=a² 0=0
ab-a²=b²-a² aa-a²=a²-a² 0=0
a(b-a)=(b+a)(b-a) a(a-a)=(a+a)(a-a)
a(0)=(2a)(0) 0=0
a=b+a ........ after replacing variable this makes NO sense, but I cant really explain it.
a=a+a
