God forbid you're made to apply your knowledge in unfamiliar situations!      It took my 15 year a couple of minutes to come up with the answer but they have been doing a lot of algebra this term.

  Re: A mathematical Friday Thread
I remember during my GCSE equivalent exam in Scotland they expected you to know how to convert metric to imperial which was clearly a mistake as it wasn't in the syllabus!
But it's marked on a curve so adjusted for difficult years. Kids just have twatter to moan more these days

I couldn't solve it straight away but got bored quickly. I'm sure I would have got there if I concentrated a bit longer

  Re: A mathematical Friday Thread  Quote:      The biggest problem I see with this question is that it doesn't explain what n is, but expects you to know the standard terminology. I hate that sort of thing, always did.      I are an illiterate idiot, it would seem.

  Re: A mathematical Friday Thread  Quote:      'There are n sweets in a bag'      Maybe they needed to say "where n is a positive integer".
But then they'd need to define the word "integer" in nonsexist, nonageist terms, in multiple languages... right, Phil?

  Re: A mathematical Friday Thread  Quote:      That's actually understandable. They're beancounters, not sweetcounters      In any case, how many accountants have degrees in mathematics? Approximately none, I'd wager.

  Re: A mathematical Friday Thread
It's a shame that the person who set out the solution in the Daily Fail article couldn't get it right! The intent was there but the expression was lacking (corrections in red)missing parentheses make all the difference!
"The chance of getting two orange sweets in a row is the first probability multiplied by the second one: 6/n x 5/(n–1) The question tells us that the chance of Hannah getting two orange sweets is 1/3.
So: 6/n x 5/(n–1) = 1/3
Now rearrange this equation.
(6x5)/n(n1) = 30/(n² – n) = 1/3 = 90/(n² – n) = 1 This is nonsense, since 30/x clearly can not equal 90/x. The last equality should be written on a new line."

If someone would only correct the spelling of Einstein in the options above.

  Re: A mathematical Friday Thread
OK. But Asian children are a bit brighter, and here is a similar exam paper puzzle from there. I could solve it, but the exam would have been long over before I could deliver the answer: http://www.theguardian.com/science/a...hatwentviral

  Re: A mathematical Friday Thread  Quote:           Personally I would disagree with "brighter". I just think it's a difference in the way that they're taught. The eduction system in England these days is, IMO, so faffy and concentrated on the soft subjects that there's no way that kids will learn the skills to cope with these logic problems, which often require little thought other than the knowledge to setup suitable matracies to eliminate that which is not.
From what I understand Asians are schooled way more intensively on hard subjects  hence the better performance with these type of questions.
By the way that question would have had me stumped as well.

In other words it's a completely different, and more advantageous, education culture.
Kids coming out of the UK education system are lucky if they can read and write these days. OK that's probably an exaggeration, but I think all of you old and wizened Brits here know where I'm coming from.

BTW, all three of my grandchildren are part Asian, as are two of my stepchildren.

Tom      Ah. Yes. But that depends, of course, what the other part is. It could have a severely diluting effect.

But I wouldn't say it's characteristic for all of the Asian countries, only for a few selected ones  Korea, Japan, Singapore, Taiwan and some other regions in China. (maybe more but defo not all of them)
