I actually mentioned the symbols awhile back. One specifies long division and one doesnt. The thread title and OP reference the long division symbol. -
My FB friends is split so far. This makes no sense Lmao

i hope you guys figured out that this is 288 by now.
multiplication and division are ranked the same in order of operations so you go left to right at that point. parenthesis first then multiplication or division from left to right and then addition or subtraction from left to right.
also you can verify this by doing a google search for 48 / 2 (9 + 3) or using a good calculator.
smh...lol i swear some of u ? should sue ur teachers...the answer is 2...stop trying to ignore the fact that the 2 is attached to the problem in the parenthesis...LOOK at how it's written...you always target the problem in parenthesis and the 2 is part of it...why would you abandon 2(12) as a problem in itself???? -
48÷2*(9+3) = 48÷2*(12) = 48÷24 = 2
explain to me why you wouldn't do it this way and I'll leave it alone...
no matter how u look at it...you do parenthesis first, multiply the 2 towards the 12 thats still in parenthesis(there is no argument to that...NONE..so don't try to make one up) and then u do the simple left over division...you get 2. YOU DONT DIVIDE BEFORE YOU MULTIPLY!!..thats basic algebra, u do left to right when the problem is completely broken down, not during. This problem is not supposed to be that difficult. yall making up rules n ?
I can only say this is how I was taught to do it, and copy/paste the response of someone more knowledgeable.theRussian wrote: »It's not.
PEDMAS is completely ? and doesn't understand that Division and Multiplication has the exactly same order of operation priority, therefore whatever one comes first is the one that takes priority.
It's 288, this is not up for discussion. We are not reinventing the ? damn writing styles of basic math.
ORDER OF PRIORITY:
Parentheses
Exponents
Division == Multiplication
Summation == Subtraction
If you see any of the ones that equal each other next to each other, you do the one left-most first, and then the next. Again, this is not up for discussion. Thread over. -

that isn't true in this algebraic equation tho...because that 2 is right next to that parenthesis..it becomes apart of that problem... people are ? up by writing it out and seeing it as :48 ÷ 2 x (9+3) and then 48 ÷ 2 x 12... thats causing people to see it as a separation when it's not -

LMAO and what makes that person more knowledgeable??? because the answer they got and the one u got are the same?? gtfoh -

No, I consider him more knowledgeable because his a physics major, which just lets me know that he is pretty good at math. -

physics majors aint never wrong?? lol aight..smh. Even tho I see how 288 was created, but why would you separate terms in algebra. 2(9+3) is a problem by itself...YOU HAVE TO FACTOR THIS ? FIRST...but aight, whatever yall say...smh
this is the same as:
48
2(9+3)
right??....so why wouldn't you complete the 2(9+3) first? lol where is there a professor when u need one?
-
Consider this: 48/2x=2. Solve for x.
the relationship between 2(9+3) and 2x is the same, right or wrong? -

Didn't say that. My initial answer was 288, and at first I was unsure, until someone I consider to know more than me came up with the same conclusion, and I don't multiply 2 with 12 because 2 is not within the parentheses, so I don't include the 2 with 9+3.
If it was written like this my answer would have been 2.
48÷(2(9+3) -
Scientific calculator says 288
-
straight from a professor:
Lower Level Math Before Theorems and Properties Have been Introduced = 288
Higher Level Math After Theorems and Properties Have been Introduced= 2
lol so i guess both can be right.....BUT ? THAT..the answer is 2!!! lol
other proof...note the separation..smh
You decide...im done..smh -
The answer doesn't end up being 2 because there is a 2 next to the parenthesis, it ends up being 2 because you've included the (9+3) in the denominator.smh...lol i swear some of u ? should sue ur teachers...the answer is 2...stop trying to ignore the fact that the 2 is attached to the problem in the parenthesis...LOOK at how it's written...you always target the problem in parenthesis and the 2 is part of it...why would you abandon 2(12) as a problem in itself????
No matter how you treat it, as long as you initially include the (9+3) in the denominator, the answer is the same:
That's the difference.

shortcuts FTW bruh...didn't even have to go thru all that to kno it was 2 tho... but props for the extended explanation of getting the correct answer -
lol. The answer is 2. Anyone who thinks its not will also vote for Sarah Palin in the next election

This thread can be used as a model example of why im against the prussian education system in its current form. the issue doesnt have to do with order of operations like most here are mistakenly assuming. it has to do with whether the term (9+3) is in the denominator or not. notation seems to be the issue at hand here. the equation can be written one of two ways. and due to the intended ambiguity of it, the ÷ symbol can represent separation from numerator and denominator. where everything to the left is numerator and everything right is denominator. but it can also represent and be synonymous with the / symbol which implies division. but without any added information, the most normal and basic conventions take precedence. so the same way implicit multiplication implies that 12x is the same as x*12, we can also assume that in this instance 48/2(9+3) is the same as 48/2*(9+3). which the answer will ultimately be 288. but the answer can be 2 as well if the creator of the OP intended for the ÷ symbol to imply long division. but since we dont have that information at hand, we cannot add conventions that are not there

lmao @ me just seeing this......yall are hilarious
-
?
Y'all should be out rioting with how public schools do you
Non fraction ass ?
It's 2 -
square root of 69 is 8 something...

What I do know is if I got a problem like this in class and said 2, it would have been counted wrong.
/shrug, maybe they do things different in the midwest.
