Why have you assumed (9+3) is in the denominator here?major pain wrote: »People. These are different problems
48/2(9+3) = 2... -
the answer is 288..there ive made up my mind it was my orignal and now my final answer....close thread the ? has been answered.

In order to solve it you have to distribute the 2 first. So, 2(9+3) = 18+6 = 24
48/24 = 2
Thank u!
Math wasn't my absolute strong suit (only got up to Trig and a dash of Business Cal), but this is pretty basic. -

The 2 will factor into whats in the parentheses. -

Yes excel is wrong too -
yes they do
when there aren't anymore equations to solve within the brackets, then you move on to the next available solving step. In which case, would be Multiplication/division.
Break this down.
48/2(9+3)
1. 2(9+3) = (2*9+2*3) = (18 + 6) = (24) NOW the parentheses go away
2. 48/(24) or 48/24
3. 2 -

The parentheses dont go away by adding 9+3.
It doesnt go away until there are no factors outside the parentheses. The 2 being there modifies whatever is in the parentheses. 48/2(12) = 48/24
no you dont...once the operations in parenthesis are completed then you back to the beginning and start applying the order again which would be division first...
you are solving the equation as if it was written like this 48/[2(9+3)]..think about it
ive spoken...close thread. -

No because 2(12) is the same thing as 2*12. -

2*9=18 2*3=6
18+6=24
48/24=2
That's the long way
I broke it down so ya'll can see it,its 2 -

Because you are separating 48/2 and multiplying it by (9+3) you will come up with 288.
Again.
48/2(9+3) is different from 48/2 * (9+3) -
the answer is 2

48/2(9+3) is different from 48/2 * (9+3)
no its not the * is undertood on the problem on the left..stop it now...for your own sake..my last post on the matter. -

When there is a number DIRECTLY outside the parentheses, that number factors in. -

This nikka's a genious! LoL -

Maybe, my binomials and ? are rusty. This ? is out of my lane. I got 2 at first, then 288. There seems to be 2 different answers depending on how you interpret the equation. -
The answer is 2.....ummmm
-
288..........

Why would a 2 factor into the parenthesis alone, when it's 48/2 and not just 2? 48/2 would factor in.major pain wrote: »The 2 will factor into whats in the parentheses.
See the examples in the third pic:

@ the bolded... you are doing the steps wrong. you don't multiply then divide, you do the multiplication/division in whatever order they come in from left to right,
I'm not multiplying and then dividing. The first step in PEMDAS is Parentheses. You have to solve whats in the parentheses first. Consider 2(x+2) and 2x+2. Those are 2 different problems. You have to get rid of the parentheses to solve the problem, the way that "should" be done is by distribution.
I'll say this much. I understand why 288 comes up. And the problem is written specifically to confuse or left to interpretation.
48
---- (9+3) = 288
2
48
= 2
2(9+3) -

As the problem is written it "should" be assumed that the (9+3) is in the denominator. Anytime I've seen a problem like this if the portion in parentheses is not to be with the denominator it would specifically noted as such. In that case 48/2*(9+3) -
Crazy thing is, focus on ? like this is a waste of time in school. Makes you no money unless you're a math teacher. Veil over your eyes solving pointless equations.
2.............
Parentheses would only "dissolve" as you ? say if there is a 1 in front of the parentheses. Clearly there is a 2 there. -
all this for 1 math problem
-
ITS 288 YOU DUMB ? ! ? !

The answer is 288. Think about it, you are reading this sentence left-to-right...that is how you solve math problems also! Break down the brackets/parenthesis then you handle division/multiplication starting from the left.
