48 Divided By all the that comes after it
the answer is 2
x = (-b +/- √b^2-4ac) / 2a
48 Divided By all the that comes after it
the answer is 2
BTW, my goto calculator for all non graphing purposes is a casio like the one above. It came up with 2.
I wonder if I can get my money back for it being broken.
It really is ambiguous and based on context; 288 is the form that is normally used, but you'll see the rules applied in a way to get 2 in a lot of mathematical literature. It's usually clear which of the two is meant.
e.g.,
∫ x dx = 1/2x^2 + C
1/2 + 1/6 + 1/12 + 1/20 + 1/30 + ... + 1/n(n+1) + ...

I've seen some use parenthesis and commas in order to avoid the problem of putting the numbers together: (24,12)*
Should look like this instead:
48
2(9+3)
That makes order of operation simple.
TheMachine is asian. Someone page him.
You do what is inside the () first.
48÷2(9+3)
48÷2*12
Then you do M or D from left to right.
24*12
288
Google calculator gets it right.
You have to add () around 2(9+3) to get 2.
48/(2(9+3))
Parentheses from inside out.
48/(2(12))
48/24
2
2
Do operations in parentheses and other grouping symbols first. If there are grouping symbols within other grouping symbols do the innermost first.
(12)
Do multiplication and division operations from left to right.
48 / 2 = 24
24 * 12 = 288
Do addition and subtraction operations from left to right

Really? It's 288 plain as day.
See, this is where math lost me, and I was like "alright, you, math."
(48 / 2) * (9 + 3) = 288
I'd rather we wait for lakaluva's opinion.
Good day, my good friends! This is Lakaluva's calculus tutor and I'm sure that I can give you pretty good insight on this simplistic math problem.
I think that the correct answer is 2 because even the machines do the calculations by parentheses. However it never interprets which has more parenthesis, but rather it does a left to right calculation. That means that you guys should properly put the equation in parenthesis from left to right since the machines interpret it that way. It's more of how we input it in the machines since the answer is obvious if we do it by hand.
If you wanted to reflect the PEMDAS rule, your calculator input should be 48÷2((9+3)).
Hope this helped you.
Good day again!

Thats different though. That in a linear equation is 48/[2(9+3)]
Thats the point a lot of people have made. IF it was the way you typed out then the answer would be 2.
x/0 = ∅
No, it's 288.
You do what's in the parenthesis first, and then start at the left side of the equation.
To get 2, it would have to be written like..
48÷(2(9+3)) = ????
what Calculuva said
This was great.

And not to pile on, but "both answers" aren't right. It's 288. You do it left to right with mult/div, basic order of operations. If you picked 2, you're wrong.
As for why the calculator said 2, it's a weirdly written problem
