Just done it on my Casio Scientific Calculator...
Did you press 'equals' after each step? Don't do that. Just type it in. Have you read the instructions?
It's not Other it is Order.
If you say Parenthesis and Exponent then PEMDAS is the mnemonic for you.
If you're old skool and say Brackets and Order then BODMAS.
Some even say BIDMAS, with I for Indices. But those people are wrong.
Allthough inertestingly, my Calculator app on my Mac, in'Scientific' mode, gives 26. 😯
It does it in 'Normal' mode too.
How confuddling!
Casio v Apple.
Hmm.......
Just done it on my Casio Scientific Calculator...
I've just done it on my Casio FX451 (last used when I was at school) and it gave the correct answer. I'd respectfully suggest that one of three things is happening here:
1) You're unable to use a calculator
2) Your calculator is rubbish
3) You're deliberately getting the wrong answer, or saying you are, to prove a point.
If I were a betting man, I'd go with 3).
TB perfectly H; I don't actually care.
All this proves is that there's more than one way to skin a cat.
If you want to think yourself cleverer than me, be my guest.
You're still a boring maths geek.
And you probbly smell too.
It's not Other it is Order.
Fair enough, must've misread. I hadn't heard of it up until this thread.
C'mon Fred, you're just bumping the thread to get a wunundred 😉
Brackets, Other, Division, Multiplication, Addition, Subtraction. Apparently. So, no.
Meh. I feel my childhood maths lessons with Mr English (ironic I know) are now wasted.
But I stick by my point that there's no equals sign so no requirement to solve.
It doesn't really matter. The equation is intentionally ambiguous so that the nerds of the world have something to discuss other than star trek.
You're still a boring maths geek.
Yes but you're still wrong! 😉
Being good at maths is just an evolutionary dead end, and is slowly being bred out of humans by natural selection. It confers no advantage over being a celebrity.
So we shouldn't be surprised that so few people understand this question and get the right answer.
Elfin - if you got the wrong answer, it's because you're sexier.
In fifty years time, no-one will get the right answer.
Are you suggesting that I've obtained it through deception? 😯
That's slanderous or libellous or defamatory or something. 😐
See you in court.
Yes but you're still wrong!
How can that actually be possible? 😕
Don't be so silly. Go and have a think about what's you've just said, and ponder the folly of your actions.
I'm going to ponder what to have for supper. Prawns and mussels with seaweed stir-fry? Or chicken and mushrooms in herbed garlic butter?
THE RUDDY PLANE TAKES OFF

Well there goes the post I was composing about arty types' Macs giving the wrong answer (the calculator on W7 also gives the correct answer).
The calculator on my cheap as chips mobile phone also gives the correct answer.

"Addition and subtraction have equal value, despite what that BOBBINS thing will have you believe"
OK. I never thought about it.
Is division also equal precedence to multiplication?
I expect to see some proof? 😉

I bet Steve Jobs would have got the right answer. I bet a lot of people who worship him wouldn't.
The whole point of the BODMAS thing is to avoid debates like this....
I got an A in Further Maths at A-level, never heard of BODMAS!
No had kebab t'other night. Can't have kebab every night. Nice to have a bit of variety.
B at A level Applied maths here (probably equal to A+ in todays money 😉 ) and BOMAS rings a bell but not loudly. I thinks it's basic maths that soon gets superceded by the complex stuff.
Do avoid confusion and mistakes few scentists would would do a proper equation without parentheses as it
😯

I know the exams are getting easier nowadays but FFS we did that at primary school! And I only got a B for normal maths at A-level.
13 years ago rather than 'nowadays'
Nowadays I can't do any maths at all, brain has atrophied 🙂

That sentence appears to need some parentheses (or maybe punctuation or re-ordering of words).
The answer is 0. Any number x zero = zero.
And, actually, maths IS important, not only because it's great fun (because it makes your brain tickle) but also because it is the reason why.
3 pages in and no one has said the answer is 42
It's always 42
This place is slipping!
Any number x zero = zero.
It is, but when you then add things to it, it stops being.
3 pages in and no one has said the answer is 42
In that case, what was the question?
It was called BIDMAS when I was doing my GCSEs. I thought the answer was 0 but apparently not. Oh well. It's not like I'd need to know this in the real world.

LOL. Yes maths [i]is[/i] fun.
And here's the Maths Is Fun website to explain why you are wrong:

😀
Imagine you were doing algebra.
What's a + b + c + de, where a = 1, b = 2, c = 3, d = 4 and e = 5?
No arguments there - but that expression is exactly the same as a + b + c + d x e
But if 2x0=0
through a little rearranging this would mean 0/0=2
6x0=0
through a little rearranging this would mean 0/0=6
Therefore does 6=2? Or a million variations there-of?
Just wondering? 😉
The answer is 0. Any number x zero = zero.
And the one number which is multiplies by zero becomes zero. It's then added to 2 and then subtracted from all those other twos. Giving 26.
But if 2x0=0
through a little rearranging this would mean 0/0=2

That's right, I went there! 😆
I think it's a bit naughty the way the question is written
2+2+2+2+2+2+2+2+2+2+2+2+2+2-2+2 x 0
I think people may interpret
2+2+2+2+2+2+2+2+2+2+2+2+2+2-2+2x0 differently although I know the theory as to why this shouldn't make a difference, but the extra spaces before the x 0 are almost implied brackets.
I don't usually jump up and down shouting "I'm right I'm righ I'm right" even though I usually am but in this case it is 26.
In maths, it is right or wrong, there are no grey areas. It is 26 and anyone who says it isn't is wrong, or just trying to be awkward for the sake of it.
.
If you want a proper discussion with answers open to interpretaion go and discuss whether or not an aircraft could take off from a treadmill or whether all headsets do indeed come complete with crown races.
.
Rant over. (possibly poor rant due to lack of capitals and swear words)
FWIW Elfin is probably right about his calculator, older ones (15 years+) will do operations in the order entered and rely on the user to know how to key data correctly. Simple test; do you enter sin 45 or 45 sin? if it's the latter then th calculator won't be sorting out the order for you!
My one in the office is like this, it doesn't mean the answer's 0 though...
Engineer BTW
Ah, I was wrong, thank you for teaching me.
So, it's
2+2+2+2+2+2+2+2+2+2+2+2+2+2-2+0
26?
Yep

what ebygomm said and what waswas said on page2.
question writing fail. 😆
I know it's not zero because I went to school.
+ 1 + 1 x 0
I would say that I quickly learned that writing expressions that relied on remembering the precedence of this lot (see below) is doomed, and made a pact with Athena (Goddess of computer programmers) to use parentheses.
1 () [] -> . :: Grouping, scope, array/member access
2 ! ~ - + * & sizeof type cast ++x --x (most) unary operations, sizeof and type casts
3 * / % Multiplication, division, modulo
4 + - Addition and subtraction
5 << >> Bitwise shift left and right
6 < <= > >= Comparisons: less-than, ...
7 == != Comparisons: equal and not equal
8 & Bitwise AND
9 ^ Bitwise exclusive OR
10 | Bitwise inclusive (normal) OR
11 && Logical AND
12 || Logical OR
13 ?: Conditional expression (ternary operator)
14 = += -= *= /= %= &= |= ^= <<= >>= Assignment operators
15 , Comma operator (a particularly mental idea)
So does it take off or not? I'm confused.
jools... always open the other door... that's all you need to know!
