Ohh Boy I can’t believe that this thread is still going on……however u calculate this simple equation there is only one answer, i.e 0. There is no need to put any brackets in this equation, only if u doesn’t know the basic rules of mathematics will u feel that the equation is confusing or ambiguous.
No mistake in the equation above. anybody is welcome to solve the equation, but when anybody wants to answer it, math has its own rules/laws. equation given above, as it is, is a problem to be freely solved by every1, whoever/ whatever they are. if a couple of parentheses put somewhere in that equation, it becomes another different problem. when somebody solve it correctly, it means they know math well, otherwise, they don't. from this type of simple math, we will know how is some1 knowledge about basic math. and 0 is the correct answer to the equation above given by Qatarisun
basic aritmethics is taught same ways in all parts of the world. Some just forgot it. Higher math?, I may agree with you that it's taught differently depending on the profession you are pursuing. But the basic four (MDAS), it's the same wherever you go.
"dgoodrebel will always be the rebellious good one"
But here you asked a bunch of QLers - and then ridiculed them for getting it wrong!
Neither Greeker or I are arguing about the multiplication before addition rule. I agree with it as I have studied maths and I arrived at the answer zero. The point we're saying is that when asking people who you know aren't mathematicians (i.e. QLers!) it saves confusion if you include the brackets.
I realise if you'd done that it would have defeated the point of your post, but I hope you can see where we are coming from. We're not arguing the rule, just saying that it takes very little effort to make it easier for everyone to read.
tallg, sure not everyone is a mathematician! I am talking about people in out technical office - first. Second, if I am not a... hmm (WHAT I AM NOT???)... ok, if I am not an astronaut, i would listen with the big interest to people who ARE...and surely wouldn't argue with them...lol..
and at last, you really assume one should be a mathematician to calculate 2 by 2 plus 5 minus 9??? Wow!
THIS IS A GRADE 3 STUFF!!! too bad, that you don't remember it!
QS, if you'd asked this question to a bunch of mathematicians then I think it would be fair to ridicule them for getting the wrong answer. However, asking a bunch of QLers is a different kettle of fish!
If you were giving this equation to someone at work for whatever reason, and you knew they weren't a mathematician, I bet you'd put the brackets in, just to make sure they got it right.
not all is a mathematician, but this MDAS thing was taught to everybody, so no excuses if bracket was not placed. Maybe, some are absent on the day it was taught. At least, now they were refreshed about the MDAS rule.
"dgoodrebel will always be the rebellious good one"
thanks MD, you saved my time for explaining this for 10-th time!
Greeker, there are some things in Math, called LAWs. If you don't follow them, you get your answer wrong, or which is even funnier, you get TWO answers for 1 equation...so since you admit you were weak in Math (which is still ok! I hope you were strong in some other subject instead!), so at least don't argue, rather be happy that you learnt something new today!
MD, that is exactly what i meant to say. Anyways, I do not wish to embroil myself in an argument. I agree to what you say and do not demand that you need to reciprocate. I just hate arguments.
you are definitively wrong, greeker. There is a rule, or call it a law. Multiplication/Division before Addition/Subtraction. Every mathematician knows this law. Hence there is no need for brackets. That's only for those who have forgotten the law!
If Ahmed (who has 4) gets 2 then according to your solution he has 6 and Ali has 4. (That's wrong.) If Ali (who has 6) gets 2 from Ahmed then he has 8 and Ahmed has 2 (that's wrong either). Try again, dude.
It should be in the right format. I, for one, would have asked the teacher where the brackets were. I may not have been bright in maths, but i always made it a point to clarify doubts as and when it arises.
Seriously, i believe that brackets are an integral part of your equation. If not, out of a 100 people, 10 (like you) might get the answer. The other 90, (like me and others) might not get it.
It is not fair to give math like this and think it is obvious to the whole 100. It isnt. With proper instructions (like the use of brackets) anyone can solve it. I am not with generalising people about their math abilities just because a question was not posed in a way suitable to them. It may be just me, but i count myself among the ignorant majority (Just like those people who shocked you in the first place).

linnet, sure my math teacher was proud of me. And by the way I was graduated from the best Mathematic high school in our city.
Greeker, sorry buddy, no one equation in the world CANNOT have two different answers! it is a MATH, darling, not a History, which you can turn the way you want!!
Come on, tallg, solve this: Ahmed and Ali are friends and both have sheep. One day Ahmed says to Ali:" Hey, if you give me 2 of your sheep, we'll both have an equal number of sheep." "No", said Ali, "give me 2 of yours and I'll have twice as many as you". How many sheep do each of them have?
I disagree qatarisun. Having studied maths throughout my education (GCSE, A-Level, Masters degree) I have had it drilled into me that you should always include brackets in order to clarify whether multiplication/division or addition/subtraction comes first. If I wrote that equation in an exam paper I would expect to be marked down.
Surely the fact that different calculators work it out differently shows that the standard of multiplication first is not universally followed!
There are two ways to write the equation - with and without brackets. Writing it without them has caused confusion and resulted in the incorrect answer. Hence the equation was written poorly, as it would have taken very little to include the brackets.
I do agree with you about a lot of people having no knowledge of basic maths though!
... has NOTHING to do with me getting 5 as an answer. Even my pea sized math brain knows that BRACKETS are very important in any math equation. From what little i know of math, one could come to at least two different answers going by your instructions.
I call it ambiguous. I am sure many other people would too. This equation is somewhat similar to painting a white background with different shades of white...
tallg, sorry to say it but you are wrong, big time! It is maybe a "bad practice not to include brackets in an equation".. in grade 3-4, but not for the University graduated people (unless they are JOURNALISTS..LOL.)!
as for "large number of people coming up with two different answers", sadly LOT of people has no any knowledge in very basic math! Ask now somebody to calculate a simple proportion, and see how many people will get it right!
So don't say it's written poorly, it's rather someone's poor brain cannot get the simplest things properly!
Just notice, whoever gave the right answer, they are mostly engineers/IT guys, who deal with it basically daily..But this is stuff from really grade 3-4!!! So every single person who attended elemenatry school should know it!..And even the bigger problem is that our office is a TECHNICAL office, and it's big shame not to know such things!!
I see you are also uncertain about the right answer, that's why you came up with your "compromising".. but sorry, the right answer is ZERO! And I am surprised some people are still arguing about it…lol…
I don't think either of the answers given is wrong - I think the original equation is written poorly. It's bad practice not to include brackets in an equation, and the large number of people coming up with two different answers shows why this is!
What are the minimum requirements, when hiring a person for the position of Office manager?
Is it able to do basic math, count to 9 with their toes and not the fingers?
Probably one of the many requirements are no math, posses except organizational skills, be able to take notes in short hand, type 20 words per minute, surf the web, interpretation of company policies and dress nicely.
This is enough typing for me, I'm not the one, claiming to be a mathematical genius.
For you, Mr. Paul: the advisor says to the Sheikh, I'll get a camel from your neighbour, then you'll have 8. Now your first son gets 4 (half of all), the second son gets 2 (half of the first son), and the third gets 1. That's 4 + 2 + 1 = 7, and then I'll return the other camel to the neighbour. The Sheikh died peacefully after that.
Problem: Evaluate the following arithmetic expression:
3 + 4 x 2
Solution:
Student 1 Student 2
3 + 4 x 2 3 + 4 x 2
= 7 x 2 = 3 + 8
= 14 = 11
It seems that each student interpreted the problem differently, resulting in two different answers. Student 1 performed the operation of addition first, then multiplication; whereas student 2 performed multiplication first, then addition. When performing arithmetic operations there can be only one correct answer. We need a set of rules in order to avoid this kind of confusion. Mathematicians have devised a standard order of operations for calculations involving more than one arithmetic operation.
Rule 1: First perform any calculations inside parentheses.
Rule 2: Next perform all multiplications and divisions, working from left to right.
Rule 3: Lastly, perform all additions and subtractions, working from left to right.
The above problem was solved correctly by Student 2 since she followed Rules 2 and 3. Let's look at some examples of solving arithmetic expressions using these rules.
The old Sheikh is about to die. He calls his advisor and says: "I have a problem. As you know I have three sons and 7 camels. I want to give my first son half of my camels, the second son half of what the first gets, and my third son shall get half of what the second gets. I cannot die before I solve this problem." Can you help him, Mr. Paul?

I agree with you on that one, without the parenthesis the answer is 5, with the parenthesis is 0. I was wondering, who is the one, that cant do basic arithmetic. Is it The pencil or the brain of that person?
Whats this I see, QL's geniuses are screwed up in Maths...geeeeezuz people, now shall we start sitting in class 1 for all you who got 5...and this time in this class Khanan is gng to be the teacher for the girls, and FS for the guys...happy happy...and everone else who isnt happy with the proceedings can come to MOI!!!
in despite of me being blond, i did the highest Math (the stuff of 1-2-3 years of University) in my 9-10 grades in school.. I am talking about integrals, Mathematics series, probability theory, etc..
I guess I know for sure how to calculate the simplest arithmetic equation...LOL..
the bracket, multiplication comes first before addition. It's actually a tricky but legitimate arithmetic quiz. Sometimes we just tend to forget our basic math. Because of the calculator, we forget to memorize our multiplication table, addition table, etc etc. Only the dining table not forgotten, hehehehehe.
"dgoodrebel will always be the rebellious good one"
LOL.. if there are NO brackets then multiplication comes first always its a mathematical rule since grade 3 or grade 4? LOL .. if there were brackets then the ones in it will be first solved..
It is not a third degree differential equation . Exponential and logarithmic functions first , multiplying and dividing second , plus and minus last priority .
that's what I said earlier, you get a different answer if you do the maths on a calculator :). But I still think, like DohaSteve said, it should have been written down like:
It depends entirely on where you put the parentheses (). If they are not shown, then you follow the order that the digits are in, therefore the answer is 5:
5 + 2 = 7 x 2 = 14 - 9 = 5
With parenthses around the (2 x 2) part, the answer becomes zero:
5 + 4 - 9 = 0
.
"I told the doctor I broke my leg in two places. He told me to quit going to those places". - Henny Youngman
now a question: do you think the calculator follows the rules of mathematics? Probably, yes. Okay, type 5+2*2-9 and you'll get 0. But as mentioned before, there is a rule: multiplication and division come before addition and subtraction, no matter if there are brackets or not!

It's PEMDAS the order of operations.

M and D are equal. They are on the same level of "importance". You do them "in order"
Hence, you get 0

"When you discover mathematical structures that you
believe correspond to the world around you . . . you are
communicating with the universe, seeing beautiful and
deep structures and patterns that no one without your
training can see. The mathematics is there, it’s leading
you, and you are discovering it. Mathematics is a profound language, an awesomely beautiful language. For
some, like Leibniz, it is the language of God. I’m not
religious, but I do believe that the universe is organized mathematically."

if you are not a mathematician, tallg, then don't touch it.
By the way: Let's call Ahmed "x" and Ali "y", then we would write
1.) x+2=y-2 (if Ahmed gets 2 and Ali loses 2, both have an equal number)
2.) 2(x-2)=y+2 (if Ali gets 2, he has twice as many as Ahmed)
3.) write 2.) as
2x-4=y+2 and subtract 1.) from 3.) you'll get
4.) x-6=4 which gives you x=10
Use that result in 1.) and you'll get
10+2=y-2 which gives you y=14
If Ahmed (or Ali) who has 10 gets 2 from the other who has 14, both have 12.
If Ali gets 2 from Ahmed who has 10 Ali will have 16 and Ahmed 8 which is half of what the other one has.
Easy, ain't it??

hello all, still having fun as i see, missed u all. good morning DA :)
The old Sheikh is about to die. He calls his advisor and says: "I have a problem. As you know I have three sons and 7 camels. I want to give my first son half of my camels, the second son half of what the first gets, and my third son shall get half of what the second gets. I cannot die before I solve this problem." Can you help him, Mr. Paul?
answer is 5 !!!
Thank you and goodnight.

If 198 yellow buses enters Doha on a Friday and each bus contains 148 horrid bachelors of whom 89% clear their throats upon arrival how many buckets of phlem will that equel?
hehehehehehehehhe!!!! i guess Mr. paul does have 11 fingers :P
WYSIWYG
MR PAUL, you are taking about solving problem! You have to know WHAT exactly you calculate! in you example the equation will look like:
(5+2) *2 – 9 = 5
you include into brackets sum of 5 & 2, because you want to calculate it first! THEN you doulble it!
uuuhhh, man you have also the problem with problem solving!!!
go go to Grade 3!! NOW!!!
If he has 7 apples and his wife brings him double the amount it means that his wife got him 14 apples not 7.. so 14 + 7 = 21 apples..
His son eats 9.. so he has 12 apples left.. :P:P:P
WYSIWYG
Some people will accept candy as normal change(currency) in Doha, while spending their hard earn money. While expecting the correct change.
I agree with you on that one, without the parenthesis the answer is 5, with the parenthesis is 0. I was wondering, who is the one, that cant do basic arithmetic. Is it The pencil or the brain of that person?
"Don't make me write your name on my TURD List!"
Mr. Paul, I bet you have 11 fingers. Start counting from your right hand: 10, 9, 8, 7, 6, and then add the other 5 from your left hand.!?
Whats this I see, QL's geniuses are screwed up in Maths...geeeeezuz people, now shall we start sitting in class 1 for all you who got 5...and this time in this class Khanan is gng to be the teacher for the girls, and FS for the guys...happy happy...and everone else who isnt happy with the proceedings can come to MOI!!!
ZZZZZZZZZZZ change the subject please....its soooooooo DUH!
in despite of me being blond, i did the highest Math (the stuff of 1-2-3 years of University) in my 9-10 grades in school.. I am talking about integrals, Mathematics series, probability theory, etc..
I guess I know for sure how to calculate the simplest arithmetic equation...LOL..
I'm glad I use a calculator & put a formula in for everything in my spreadsheets :)
He has 7 apples.
Now his wife brings him double that amount, he now has 14 apples.
If his son eats 9 apples, he is left with 5, NOT 0 !!!!

Mr Paul, Mr. Physics, if we could convert your mass (in kg) into energy (Joule), how much would it be?
Mr.P, YOU HAVE TO GIVE A PRIORITY TO MULTIPLICATION..
then you put on paper:
2 x 2 = 4
5+4 = 9
9-9 =0
THERE IS NO ANY OTHER WAY!

the bracket, multiplication comes first before addition. It's actually a tricky but legitimate arithmetic quiz. Sometimes we just tend to forget our basic math. Because of the calculator, we forget to memorize our multiplication table, addition table, etc etc. Only the dining table not forgotten, hehehehehe.

LOL.. if there are NO brackets then multiplication comes first always its a mathematical rule since grade 3 or grade 4? LOL .. if there were brackets then the ones in it will be first solved..

thank you teacher, will do!! :(
= 0
You don't need brackets .
It is not a third degree differential equation . Exponential and logarithmic functions first , multiplying and dividing second , plus and minus last priority .

:( Rven my calculator is dumb at maths. :(
Visit www.qatarhappening.com
that's what I said earlier, you get a different answer if you do the maths on a calculator :). But I still think, like DohaSteve said, it should have been written down like:
5 + (2 x 2) - 9 = ? and not 5 + 2 x 2 - 9 = ?
you need brackets if you want to give a priority to the lower level in calculation.
for example , if you want the sum of 5+2 to be calculated FIRST, then you have to include it in brackets!
(5+2) x 2 -9 = 5
Otherwise multiplication comes first by default!
5 + 2 x 2 -9 = 0
Sorry Gypsy, I put it in mine, and it says 0.
listen to you maths teacher now..
sssssh all quite..
simple rule of maths.....BDMAS..
Brackets-Division-Mulitplication-Addition-Subtraction..
this the series to follow.....
whenever in a multieuation the above series should be followed..
now you all dumb heads (ppl with "5" as soulution) write hundered times in your copy..BDMAS.....:)

yeah agree QS... even in marriage.. which comes first?
as written on the book, go and multipy... lolz...
then add and add more...
tehn share and divide... lolz..
subtraction comes always behind...

Sorry Magic Dragon, I put that in my calculator and it came up 5.

In the UK I worked in credit control, finance. Good job that I had a formula for everything set up on my spreadsheets :)
It depends entirely on where you put the parentheses (). If they are not shown, then you follow the order that the digits are in, therefore the answer is 5:
5 + 2 = 7 x 2 = 14 - 9 = 5
With parenthses around the (2 x 2) part, the answer becomes zero:
5 + 4 - 9 = 0

now a question: do you think the calculator follows the rules of mathematics? Probably, yes. Okay, type 5+2*2-9 and you'll get 0. But as mentioned before, there is a rule: multiplication and division come before addition and subtraction, no matter if there are brackets or not!

~~~ There is no substitute for victory yet there is risks of too much oversight... ~~~
but as I said earlier, if it had been written like
5 + (2 x 2) - 9 = ?, I would have got 0 :(
lima and Mr.P, are you guys bith journalists as well??..lol..
was in brackets, then its 0. Yer gotta read the question properly.

..sure it's 0.. but this is a problem, some ppl (and they are NOT JOURNALISTS!..lol..) got 5 as an answer...
uf.. thanks guys.. i thought something wrong with MY mind and memeory.. but no, i am still ok...lol..
