I don't recall ever being taught the acronym to be honest.
We were just expected to know the correct order. It isn't exactly hard (for most).
I'm in complete agreement. But at 9 its difficult to grasp that the acronym is immaterial, and this hazy (at the time) concept of operator precedence is rather important ... particularly if you can get all the way to a B at A level completely ignorant of operator precedence beyond 'do the stuff in brackets first' 🙂
You're all missing the point - emsz was offering to strip off for £20.
Yep, I don't now how anyone managed to get through algebra if they didn't understand that:
[code]A = B x C + D[/code] is the same as [code]A = D + B x C[/code]
or what order they should do [code]ax² + bx + c[/code] in.
You're all missing the point - emsz was offering to strip off for £20.
She was not, actually. Only in your sick, twisted depraved stinking cess-pit of a mind....
I was once offered I think it was twenty pounds or something to strip for some lasses out on a hen night, as the stripper they'd booked had cancelled.
[i]Twenty pounds[/i]. For a bunch of leering lewd coarse women to debase me to nothing more than an object for their sordid sexual gratification.
Actually, now I put it in those terms.....
Fiddlesticks. 😐
It's a fairly simple point, which I doubt is well-explained to school children: that different machines may give you different answers for a given input, none of them necessarily correct.
But the point of teaching people maths, and the conventions of maths is that everyone works with the same ideas about what's going on. it's a language. Unless you're breaking new ground (and we're really not here!) you can't answer a question according to your own logic and claim that it's equally valid. Or turn up for an interview at an engineering company and say that you prefer to work in base 8 but 12 on a Wednesday.
Edit: didn't read your posts properly. Don't disagree with you, but don't entirely know what you're arguing? Saying that people shouldn't be quoting results from caluculators to support their answers?
Many here have argued that those who get the wrong answer don't know how to use a calculator. Then we discover that different calculators work in different ways. All I'm saying is that it's a little less simple than claimed.
y=2+2+2+2+2+2+2+2+2+2+2+2+2+2-2+2a
where a=0
y=2+2+2+2+2+2+2+2+2+2+2+2+2+2-2+(2*0)
y=26
I wasn't offering to strip for £20, I did a life class and got £20 for expenses. 🙄
They gave me a white robe to put on and a cup of tea half way through, it was all v. civilized 😀
[i]Hmm. Maths is dumb. If you have something and then multiple it by nothing, then how can the something that you had suddenly become nothing? Where's the logic in that?[/i]
The logic is that to multiply by zero means to take it all away. Duh!
(sorry, only read the first page)
£20 for still life? How much for you to move about a bit?
(-:
thankfully the question isn't:
2+2+2+2+2+2+2+2+2+2+2+2+2+2-2+2 / 0
which = infinity
Only a very little bit less simple, though: those getting the wrong answer from a calculator don't know how to use [i]that[/i] calculator.All I'm saying is that it's a little less simple than claimed.
really.... WTF does it matter?
no-one would write that down unless they were a bit of a pillock (can you say pillock here?) and wanted to wave their mathematical willy.
i deal with numbers everyday in my job as a carpenter. i have to add and subtract, multiply and divide daily and consider myself resonable at maths.
if truth be told maths is bollox when you start with the whole BODMAS stuff. it's just stuff that has literally been made up - bit like religions in that sense.
i'd say that over 99% of the population would never come into contact with that sort of sum during their lives. and if they did they would answer 0 because as we all know anything multiplied by zero is 0....

Well that's math for you. To use math is a bit like to drive a car, they are rules to follow.
i'd say that over 99% of the population would never come into contact with that sort of sum during their lives. and if they did they would answer 0 because as we all know anything multiplied by zero is 0....
Well it probably means 99% of people are morons who never listen in class. You learn about the rules when you're 12.
And as for the calculator, math/physics teachers would tell you do get one that abide for the standard rules of mathematics.
For the record I said 26 too... Dr geek in computational science here.
no juan, they're not morons.
do you remember everything you were told at school? we retain information that we find interesting or useful to us.
how useful is it to know that the equation equals 26? surely if you do find that useful then you'll be using it on a daily basis.
Well it probably means 99% of people are just normal and get on with their lives instead of worrying about the order of useless things and boring maffs stuff.
FTFY....

Thankfully that leaves the remaining few (1%), some of whom may have the ability to apply it for the benefit of the 99%, for example, as a probabolistic design tool to understand the design space for such things as carpentry power tools to ensure the product is safe, effective and reliable.

Yeah. Theres too much smuggery (may not be a word) in this thread.
Take any single specialist skill, knowledge or technique and 99% of the population would be oblivious to it's significance and incapable of it's execution - doesn't mean it's useless though does it ?
The disingenuous "maffs is for losers innit" comments are so reminiscent of people who boast they can't put together a flat pack cupboard, don't 'get' art and haven't read a book since they left school; rather than admit they're unskilled/uneducated in that particular skillset they wear their ignorance as some kind of 'badge of pride' and sneer at those who can.
When possession of specialist skills or knowledge makes you the object of derision it reminds that a wise man once told me the curse of the modern age was something he called "the conspiracy of mediocracy"
🙄
Smugnitude = An overwhelming, huge amount of smugness.
probabolistic
Do what? 😕
When banging on about something that's a load of cobblers and has no actual relevance in the Real World just to try to sound clever makes you the object of derision it reminds what a complete waste of time being a swot really was.
FTFY...
Elfish = a complete inability to recognise the value of something that doesn't conform to your own compromised world view, innit
Listen sunshine; when you can even comprehend a fraction of the World of Elf, then you'll have attained a level of enlightenment most will never experience, and can only ever dream of.
I can help guide you, but you must learn to see for yourself, not be blinkered by the foolishness and choopidness of others....
Do what?
let me reach out: [i]check it on wiki innit[/i]

You are probably right - which makes it depressing to think that our democratic system gives a majority vote to a group of people lacking the education or reasoning faculty to make a logical decision.
U mite now maffs but yor spelins rubbish m8. 😉

...but does explain the low quality and standards of government we have 😡
PMSL that this thread is still giving!
so many IT/computing bods on here and a subject close to heart.
of course its only due to the existence of those troll-ass spaces in the original 'sum' that we are beyond page one.
lets just imagine that the last two digits were 1. all sides would be happy! 😀
Yeah but it's good to have a nice argue now and then, innit? 🙂

No it isn't.

Good gravy. It's not like it's some obscure fact from third year History about who the third cousin twice removed of Alfred the Great was; it's basic, [i]basic[/i] stuff.

This, good god, this ^2. I hear that a lot in my job, "I don't know anything about computers, me" all smug and proud, when they're a gorram secretary or accountant for a living. It's like a taxi driver without a driving licence, "I don't know anything about cars, aren't I clevar." Well done.
Different people have different skills and abilities, and I understand that. There's plenty of stuff that's a complete mystery to me (chemistry for one, baffles the crap out of me). But please, please don't be telling me you're pig ignorant of something whilst you've got a self-fulfilled grin on your face like it's something you've worked hard to be proud of.
No it isn't.
Yes (it is)! 😀
That's not an argument, it's just contradiction!

Whit? . You never have to do maths?
5 x £1 + 4 x 20p? How much is that? Oh look you just used that "whole BODMAS stuff" that no one uses. 🙄
5 x £1 + 4 x 20p? How much is that? Oh look you just used that "whole BODMAS stuff" that no one uses
Fish and chips twice, please.
(You're right, but you're cherry picking.)
Now do it 5x1+4x0.2
1.8
5.8
5
😕
Question: why do you maffs geeks find it so important to be 'right' on this, and to be 'superior' to others? Are you quite insecure? Does being a geek make you feel a bit inferior to others, to the extent you feel the need to compensate by out-clevering others and claiming they're thick?
Just that that's how you're coming across tbh.
5 x £1 + 4 x 20p
What normal person thinks in equations like this when sorting their coins though? I just sort my coins into individual piles and add them up. Maybe I'm just thick though.
(You're right, but you're cherry picking.)
I'm allowed to 😀 he said it was bollox and 99% of the population never use.
I'm just trying to demonstrate that in fact most people use it all the time but just don't realise it.
5.8

How do you count the coins in your pocket?
If I've got five pound coins I go £1 x 5 = £5.
Is that unusual?
It's got nothing to do with being superior to others... that just comes naturally.. 😉
It's because in maths, exactness is important, and that is easily seen by the original question and differing answers. It's because there is a definite right answer, and that by trying to explain it to those who do not understand, that maybe they will learn something...
Learning stuff is always good... I learn new stuff every day...
I individually count how many I have. This is a moot point anyway as I never have that much change on me 😆
You're right Tom. Any sensible normal person would just count up what they had ion their pocket/moneybox/purse/coppers jar. I spose if you were sorting through different coinage you might 'bracket' them according to value, but that's about it I spose. I see where Graham's going with that, but it does not in any way justify or back up his claims for twenty six as opposed to zero.
I think what it is, they can't admit there's different ways of doing stuff, and that normal people would do the sum in a logical fashion, rather than dreaming up brackets an ting.
'Ooh I'm an engineer' yeah but your wife is thirty six and from Holland. 😐
Work that one out then, geeks! Ha! You weren't expecting that, were you? Where's your maffs now come save you, eh?
And here we go, here we go-
BOSH!
I can't see them coming back from that one. 😀
5.8
Not if you don't use BODMAS. If you do it left to right then it is
5 x £1 + 4 x 20p
= 5 x 100p + 4 x 20p
= 500 + 4 x 20
= 504 x 20
= 10080p
