48÷2(9+3) = ?

[dave the caveman]

What's the foxestalk take on this very important question?

[jonthefox]

I went to the university of thick as fook, so no point asking me.

[Trav Le Bleu]

288

EDIT: was posted before options went up.

When I was taught mathes (over 20 years ago now) the equation inside the brackets was to be solved first and then factored by the numbers outside, so essentially 24 (12) or 24 12s or 24 x 12.

If the answer was to be 2, then the equation should look like

48÷2

(9+3)

[Mee]

288.

But now i think it's 2.

[Trav Le Bleu]

Alternatively I suppose it could be read as 9+3 (=12) x 48 (=288) ÷2 = 144

[lcfc"weasel"]

I'd answer it, in that form, as 2.

48

2(9+3)

48

24

2

However, it's impossible to say exactly without seeing it written as a fraction.

[Trav Le Bleu]

48

2(9+3)

48

2

Just had a word with a maths teacher and had a good long look at it and now I think you're right

[Wymsey]

I initially thought and voted for 288 as i would work it out the way Trav did/learnt.

[Phube]

48

2(9+3)

48

24

2

That's what I'd say...

[Trav Le Bleu]

Actually I'm swinging back to my initial answer. My teacher accomplice was wrong (fairdoes, he admitted it)

To get a result of 2 the equation should look thus.. 48÷(2(9+3)) =

As it stands, it's 288

[potter3]

I don't know how you could get anything other than 2.

[danny.]

its 288

[Haydos]

288.

[James18]

9 + 3 = 12

48 ÷ 2 = 24

24 x 12 = 288

Simples.

288 I reckon. Ever since year 7 i've had BIDMAS drilled into me. Brackets Indices Division Multiplication Addition Subtraction.

so it would be brackets = 48 / 2x(12),

then Division = 24 x12

then multiplication, giving you 288. These sort of problems need to be taken very seriously.

You don't add the numbers to gether in the bracket you multiply them each seperately with the outside term, for example:

x(x+1) would give the answer x^2 + x.

It's actually spelt Pi.

That's how I interpreted it it initially. It's written in such a retarded way though that you could get to either answer (either (48/2)*(9+3) or 48/(2*(9+3)) ). I'm guessing that was the OP's intention.

Having read through the posts, I'd completely forgotten BIDMAS and I work with statistics and numbers every day

x(x+1) would give the answer x^2 + x.

It's the same either way, 2x9 + 2x3 =24 ; 2x(12)=24. But because the 2 is used in the division of 48 (by the laws of bidmas) then you dont actually times the bracket by 2 but by 24.

Wrong thread, I thought I was in 'what are you eating now?'.

The answer to this question is infinity.

I'd argue that the implication by the way it was written (the fact that it's 2(9+3) rather than 2*(9+3) ) is that they're grouped together as part of the sum, so you can shove BIDMAS It's written in such a ridiculous way, mind

Bidmas has been my maths life for 6 years, Dont take it away from me

[James18]

If you were in an exam and that question came up the way it's written there, the correct answer would be 288.

BIDMAS/BODMAS

[Asha]

I've always thought the brackets are sorted out first, so it'd be 2

[lcfc"weasel"]

Even if you sum the numbers inside the brackets, you can't just remove the brackets, it'd still have to read 48/2(12). You still have brackets so can't divide yet and therefore have to make it 48/24 and give you an answer of 2. However, as I said before unless you have it in fractional form you can't give and exact answer and you should give them both if you were to get the question in an exam also stating your reasoning as you shouldn't be able to get two answers to anything unless it's a quadratic.
