so 40+40+40+40 x 0 + 1 = 121? Title: Re: Basic maths question. Post by: kinboshi on November 11, 2011, 10:33:59 AM meh, i still thought it was 1 so 40+40+40+40 x 0 + 1 = 121? Correct. Multiplication done first, then the addition. 40 + 40 + 40 + 40 x 0 + 1 = 40 + 40 + 40 + (40 x 0) + 1 = 121 Title: Re: Basic maths question.

Post by: BrumBilly on November 13, 2011, 12:52:21 PM Not ashamed to say I got this WRONG...I simply don't know the rules of operation...maths was never my thing at school and never paid attention so won't blame my teachers, they must've shown me at some point, it just failed to sink in...so at 39 I've learned somethin pretty fundamental!!! Funny how we can be pretty advanced in some fields and entirely remedial in others....Da Vinci must've been some bloke!
Title: Re: Basic maths question. Post by: gatso on November 14, 2011, 09:03:53 AM ok, for those who still aren't getting the reasoning behind this I've just seen a fantastic explanation on the charltonlife footy forum. if you're still claiming the answer isn't 41 after this then I just give up
Quote Just in case anyone's wondering why we do multiplication before addition, one explanation is that it's because of algebraic notation. Algebra helps to shorten mathematical sentences. For example, if you have 5 apples and 3 bananas, you could call that "5a + 3b". Now bear in mind that the expression "5a" actually means "5 x a" (or "apple" multiplied by 5 if you like), so the whole expression really means "5 x a + 3 x b". Now, if you did these operations (adding, multiplying etc) from left to right, you would get, after each stage, running totals of; "5a", then "5a +3", then a final answer of "5ab +3b". Unfortunately, the "5ab" part doesn't make sense, because there is no such thing as "five applebananas". Everybody, whether mathematically minded or not, understands that if you say "I've got 5 apples and 3 bananas, you mean "five lots of apples PLUS 3 lots of bananas". This statement is translated mathematically as: "5 x a + 3 x b" and the multiplications are carried out first, the additions last. Mathematicians realised centuries ago that algebraic notation required multiplying to be carried out before adding and decided that there should be standard rules of precedence in operations when performing arithmetic. It was a natural decision to make multiplication take precedence over addition because it is consistent with algebraic notation and therefore less confusing(!!!) Now, if you consider the following situation: A person is given 42 scratchcards. He wins £40 on the first one, he then loses the next 40, then he wins £1 on the last one. How much money has he won altogether? Clearly, he has used all 42 scratchcards and his total winnings are £41. (1 lot of 40, 40 lots of 0 and 1 lot of 1) Now in order to write this down algebraically, you could consider the letters f, z and o to represent occasions where he won forty, zero or one pound respectively. This then becomes: 1f + 40z + 1o but we don't need the "1" in front of f and o, so it simplifies to: f + 40z + o but now, putting the values of f =40, z = 0 and o = 1 into the expression gives: 40 + 40 x 0 + 1 which was the question posed in the original post. The introduction of algebra to this situation may seem like it's making it even more complicated, but it's the best way I can think of to illustrate the reason why the answer can only be 41.

Post by: AdamM on November 14, 2011, 03:19:20 PM Was playing in a home game saturday and a retired primary school head master wouldn't accept it was 41.
everyone else at the table, once reminded of the Order of Operations or BODMAS agreed on 41. My 11 year old got it right straight away because she's half a term into secondary (grammar) school and it's already been covered in maths. It's an intentional "trick question" as it's supposed to make you get it wrong. Title: Re: Basic maths question. Post by: TopTen on November 14, 2011, 03:21:29 PM That is why I agree with Raman that the answer is 1
The math question in question is surely written down incorrectly? the 40 + 40 part of it should be bracketed therefore this sum should take priority over the multiplication sum hence making it (40+40) x 0 + 1 Hence the answer IMO is 1 Title: Re: Basic maths question.

I think some people refuse to accept that maths isn't the same as English language (or most written languages) Just because you read words from left to right, doesn't mean you should read maths problems from left to right.

Title: Re: Basic maths question. Post by: BrumBilly on November 14, 2011, 06:21:00 PM Doesn't seem ridiculous to me that people make mistakes when they don't know the rules to a language (in this case maths). What is pretty whacky is the 'head in the sand' attitude when corrected and introduced to universal rules, without which we'd be left guessing (which is what I was doing, seeing as I hadn't done a sum like this since school where I dropped maths and didn't sit the exam!).
Like I said, I've learned somethin that I'd either forgotten or not taken in first time round which is kinda cool! Title: Re: Basic maths question. Post by: SirPerceval on November 14, 2011, 06:28:55 PM 41 would be much more credible if Kinboshi wasn't supporting it.

Title: Re: Basic maths question. Post by: Jon MW on November 14, 2011, 07:07:33 PM I did a PGCE and a large part of the theory for teaching maths is identifying and correcting misconceptions.
What's weird is that this isn't really one of them, almost all pupils learn BODMAS and then have no problem with it. stroppy teenagers are perfectly happy to accept it but seems like some people have a problem doing so as they get older Title: Re: Basic maths question.

Not as irritating as them teaching them crap like the seven day creation myth and Noahs Arc years before ever mentioning the big bang and evolution, but that's another discussion. I guess the idea is to lay basic foundations and not worry too much about the detail. I remember my A level physics teacher telling me that a lot of the Newtonian physics I'd been taught at GCSE was wrong, and that a lot of the Einsienian physics he was going to be teaching was closet, but still wrong, and that if anyone went on to degree level, they'd be correncting us again.
