Case in point... the answer is 288

-Signed your resident UCLA Math Major

UCLA Math Major? Word?
1 - 1 + 1 will ALWAYS be 1.

(1 - 1) + 1 = 1

1 + (-1 +1) = 1  

BECAUSE 

1 - 1 = 1 + (-1)

Once again.. agreed.

If you are going to carry the minus sign with the 1 (which is obviously the correct thing to do), should you not carry the division sign with the 2?

Which would lead to 48*(9/2+3/2).. or should I go back to UCLA and get a refund on my degree?

Get a refund.

Casios are postfix calculators, I believe. So they operate on a stack and do it different. I could be wrong but I know they are programmatically different in terms of how they calculate.  Infix is the common method.

You can't just add a second parentheses to the problem. Which everyone appears to be doing.
48 / 2 ( 9 + 3 ) = 48 / 2 * 12 , The parentheses disappears after the equation inside has been solved. It then turns into 48/2 x 12

Those calling for distribution, why don't you  guys distribute the 48/ 2 into the ( 9+ 3) 

48/ 2(12) = 48/2 = 24 x (12) or as 24(12) = 288

Distribution does not apply when the second parentheses is absent in the problem.

It's not "adding a second parentheses". I'm not adding anything. It's there. It's implied.
2(9 + 3) is a simplified version of (2 * 1(9 + 3))

I used the extended version to show that you can't just pull 2 away from the parentheses and use it to divide 48. They are tied together.

In order to divide 48 by 2 it would have had to be more explicit such as (48 / 2)(9 + 3) but it's not. You can't make that assumption.

Besides, you distribute first so your argument about distribution after the parentheses are absent are moot.

It isn't implied though. As the problem is written it is this.

That's what the problem is. You can't just ASSUME there is parentheses around the 2(9+3). If that was the case, the problem would read 48/(2(9+3)) which would be 2. But it's not. It's 288.

mosk33toe keep that degree homie.

Dudes are adamant.

Here:

Fifth row down.

Yea your right.
48/2 = 24 = a

24(9+3) = 288

The P in PEMDAS means to do whats IN the parenthesis first. 12 is the ONLY thing that is IN the parenthesis. From there you go left to right order of operations.

you do know you multiply first before dividing. Number next to parenthesis is the same exact thing as multiplying therefore, you do multiplication first,which at the end will you 2 NOT 288.

This is where you cats are messing up. @48/2(12) you still have to follow the order of operations and distribute that 2 before you do amy thing else. So, you will get 48/24 which =2

Is this real life?

LISTEN!
It's 288, (*) = (/) just as (+) = (-)




I don't know where you guys learned math from but, in equations.. addition is equal to subtraction just as multiplication is equal to division.  Never mind the PEMDAS, that was just created to help the slow.

no you dont its what ever is first PEMDAS is really

P

M or D
A or S

There is a reason why on math tests you show you how its written and not just in a straight line because there is 2 ways to write that. Who knows if its the whole thing multiplied by (9+3) or (9+3) is in the denominator. Both give different results.

its 288, yall about to have Obama come in this thread and throw yall back into middle school

UTAH EDUCATION IS FAILING. The distributive therom only works in situations like this where its 2(x+1) where 2(x+1) is the same as 2x + 2.

But that's the thing. If it was meant to be the first way the problem would read 48/(2(9+3))...

 

[balloonoboy]

Let me throw another wrench in the mix.

48 ÷ 2(9+3) =

48 ÷ 18 + 6 =

2.66667 + 6 = 8.66667

After the parenthesis is distributed it doesn't necessarily have to stay a parenthesis.
