48÷2(9+3) = ????

  1. 1. What's the answer?



Recommended Posts

This is how I see it:

[spoiler=My solution]48/2(9+3)

First do distributive property:

48/((9*2)+(3*2))

48/24

2

 

At least I think it's right...

I'm pretty sure that the distributive property ignores PEMDAS, and comes before it. :???:

Edit: If I am wrong, feel free to correct me.

Distributive property doesn't take precedence in a monomial equation. Because there are no X-terms, the entire equation is one term. The answer is in spoiler tags in the first post btw.

I'm still confused. I learned it as always being first. I don't know, I'm just not quite getting it. :oops:

 

Think of the parenthesis as a multiplication sign. So, it would be 48/2×12 --> 24×12 --> 288

It's deliberately confusing.

Really should be another pair or brackets indicating whether the (9+3) is on the top or the bottom of the equation. However, yes, when it's written out like this going left to right is the correct approach.

In any case, this problem is not clear enough in terms of what's going with what, even with BIDMAS, PEMDAS, GEMA (what the [bleep] is this). It's not clearly defined how to do this problem correctly. It's still 288 unless brackets/more parentheses say otherwise.

GEMA is:

 

Grouping

Exponents

Multiplication and division

Addition and subtraction

 

Ah. Never heard of that.

It doesn't even matter whether you use PEMDAS, BIDMAS, GAMA, PETA, or whatever, it's all the same thing.

 

There's enough information to solve the problem. It may not be in the correct usage/form, but "How are you?" and "h0w r u?" both are understandable.

I really don't see how anyone who has passed basic algebra doesn't get 288...

Mathematics is strictly a logical system of numbers and symbols, there is a right and a wrong way of doing it. If it's ambiguous, it's wrong. Written/spoken languages only use a logical system as a guideline, you are allowed to use creative and ambiguous derivatives to get across subtleties. They are not the same.

 

There needs to be another bracket to clarify, or the question needs to be fully displayed to show where the (9+3) lies relative to the division line. It's not too much to ask for.

It's clear enough without it if you follow the rules.

 

You do whatever function is in parentheses first, and then do the problem from left to right with the answer you got in the parentheses.

 

We don't write 1x^1, it's just understood that whenever you see x as a variable, it's that way.

 

As such, we write 48/2(9+3) because it should be understood that it's operated like (48/2)(9+3).

Still, my general rule is to use excessive brackets when typing out equations.

 

Either way - typing math sucks :razz:

I see now how the question is somewhat ambiguous, and it's open to interpretation. Saying that, it is kind of impossible to answer seeing as they don't specify whether they want you to do 48/(2(9+3)) or (48/2)(9+3)... I'd still go with 288 though, seems more logical with BIDMAS.

How can math be ambiguous? Its one answer, no matter what. Or else it wouldn't be math.

If you were expected to do 48/(2(9+2)) then they'd specify that way.

 

Why would you give somebody 442+567 and then tell them they're wrong when they don't come up with 2.

[spoiler=Solution]PEMDAS

 

48/2 * (9+3)

=24(9+3)

 

Distributive property...

 

= 216 + 72

= 288

Aah yeah, I voted 2, but after reading, of course its 288. :mellow: I think if it had been shown like this:

 

48/2*(9+3)

 

instead of with the division symbol (which doesn't seem to exist on my keyboard :P) more people would get that answer.

You can't use the distributive property if you use Pemdas...the first letter of Pemdas is Parenthesis, which would make it

 

48/2*12...

 

Same answer, just pointing that out.

48/2(9+3)

 

Not sure if it was:

 

48/2 x (9+3)/1

 

48/2 x 12/1

 

48/1 x 6

 

288

 

48/2(9+3) could be seen as

 

48/1 x 1/2 (9+3)

 

48/1 x 1/2 (12)

 

48/1 x 1/24

 

48/24

 

2

 

Poorly written question tbh with a degree of ambiguity on whether the parenthesis are attached to the two or are a whole number.

1/2(12) would still be six as the 1/2 is outside the parenthesis, indicating that it would just be 1/2 × 12 = 6. In your equation, it would be multiplying the 2 and 12 together first, which wouldn't be going left to right.

Parenthesis wouldnt matter if they were on the bottom not the outside.

 

for example:

 

42 ÷ 2(9+3)

 

would look like the (9+3) is on the bottom of the fraction, attached to the two instead of outside it as a whole number. Idk written out of paper this wouldnt be a problem because its written as 42/1 ÷ 2/1 x (9+3)/1.

 

which comes out to the first one

 

42/2 x (9+3)/1

Questions can be ambiguous. Answers and the maths within can't be ambiguous and still be correct, even if the answer is that the question is ambiguous. The mistake here is with the syntax, not the maths itself. We're not destroying the fabric of causality here, we're just saying that the asker should have typed in a goddamn bracket.

I still don't see how this question is even remotely ambiguous. There's a reason why PEMDAS/BIDMAS/whatever exists. I don't know how your experience with math went, but I've always been given expressions with the least possible amount of brackets possible.
