leicester4life Posted 10 April 2011 Posted 10 April 2011 Alternatively I suppose it could be read as 9+3 (=12) x 48 (=288) ÷2 = 144 No-one noticed this gem? 288, all day every day.
lcfc"weasel" Posted 10 April 2011 Posted 10 April 2011 You've remvoed the brackets when you've summed the contents. 2(12) means the same as 2 x 12, so surely bidmas is applied then? Was always taught that you remove the brackets when you can simplify it down to one constant. Don't think so, it depends what'd happen if it was algebraic, but then again, with algebra rules you can make 2+2=5.
DB11 Posted 10 April 2011 Posted 10 April 2011 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. I think 288. My calculator also returns 288, which is good enough for me!
anotherharboroughfox Posted 10 April 2011 Posted 10 April 2011 Don't think so, it depends what'd happen if it was algebraic, but then again, with algebra rules you can make 2+2=5. and make 2=1
StanSP Posted 10 April 2011 Posted 10 April 2011 Eleven plus two = twelve plus one. Maths and anagrams.
Mee Posted 10 April 2011 Posted 10 April 2011 Eleven plus two = twelve plus one. Maths and anagrams. Genius. Will say this to the class at school, and maybe it will get me laid :thumbsup: But honestly, that's pretty clever
lcfc"weasel" Posted 10 April 2011 Posted 10 April 2011 and make 2=1 . Also, Pi can be estimated to 2 or 4.
Wymsey Posted 10 April 2011 Posted 10 April 2011 As Einstein used to say ''Pure Mathematics is the poetry of logical thinking.'' I can't think of the answer to this teaser so i'm no good at Maths.
Wymsey Posted 10 April 2011 Posted 10 April 2011 (48 / 2) * (9 + 3) = 288 Not hard really. Well I asked this to one of my mates on Facebook who is studying Economics and he thinks otherwise to this question (2)

lcfc"weasel" Posted 10 April 2011 Posted 10 April 2011 It's 2, finished. However, I am posing this to my further maths class tomorrow.
Parafox Posted 11 April 2011 Posted 11 April 2011 As I was banging Rachel Riley last night she shouted the answer... it is OHHHMYYYGODDYESSS!!!!!
Trav Le Bleu Posted 11 April 2011 Posted 11 April 2011 All I want to know now is this? On what day do we celebrate Bidmas?

Bryn Posted 11 April 2011 Posted 11 April 2011 I'd echo whats been said before in that that's a terribly expressed equation. I'd go with 2 if I were pushed to give one answer. I agree that (9+3) = (12), in which case you'd still have to address that calculation first. 48/2(12) = 48/24 = 2 It's loose logic, but the question is looser still. I also agree with the guy that said if you were to get that in an exam, and there was no correction offered, give both answers and challenge your mark if they mark you down. It's possibly the kind of thing they might give at a Uni interview to see how you think.

It's possibly the kind of thing they might give at a Uni interview to see how you think. I'm no maths expert (dropped it after GCSE), but surely it would be essentially written as 48/2 x 12 because there's only a single number within the brackets, therefore the brackets are now unnecessary and don't need to be part of the question? As you say though, it's loose!
