you're friend may have all those credentials but he still sucks at jr high level algebra

and its still 2

48÷2(12) which can be rewritten as 48÷2*12

Since ÷ and * are the same in order of operations, you go from left to right so 48÷2*12 = 24*12 = 288.

Quoting myself for truth.

But you lying though.

I know

Where did he get 488 from 

48 x 0.5 = 24
24 x 12 = 288 according to that logic

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.

But yeah, you follow BEDMAS/PEDMAS

48/2(9+3)

BRACKETS/PARENTHESIS FIRST,

48/2(12)

After this, those brackets are simply a multiplication symbol, so you can rewrite as:
48/2x12

At this point you follow BEDMAS and go left to right
48/2 = 24

Then you have 24(12) or 24x12

= 288

My dude, you have it all wrong... its not PEDMAS... its PEMDAS.
Its not "Please excuse dear my aunt sally" its Please excuse MY DEAR aunt sally. 

Thats why half of these dudes got it wrong 

Multiplication comes first, then division. So you would multiply the 2 x 12 before you divide it by 48. which gives you 2 in the end. 

you sure about that, bro?

so how would you answer the equation 3 + 6 - 12 - 7 + 3?

in your reasoning, if multiplication comes before division (using PEMDAS), then addition also comes before subtraction.

so i'm assuming you'd get 9 - 12 - 10 = -13 for the above equation? if so,

At the end of the day, that #%%% is 2

you work left to right if its multiplication and division there are websites that support it too

hell even google says 288
2 is incorrect
it DOESNT matter if multiplication comes first you work left to right when its division and multiplication

my vote goes for 2
asked my brother, pretty smart dude, said he thinks 2 also
this is quite the debate though

It will not always be 1. For all the people that are saying PEMDAS infers that Multiplication has more priority than Division, this means that Addition has more priority than Subtraction.  Therefore they would compute this 1-1+1 = 1-(2) = -1.

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?

[usainboltisfast]

48 / 2 (9+3)

48 / 2 (12)

24 ( 12 )

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.

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.
