What is the CORRECT answer?

[Yorkie]

Is this all a big NSC wind up or do some people really not grasp primary school maths?!?!

It seems to be the oldies who are having the most trouble. et back to school!

Maybe it is the way we were taught at school. The wording seems to be ambiguous.

 

[Deportivo Seagull]

yes then learn maths cos its not like reading a book at all

Yes .... i got it wrong

 

[nwgull]

NO it isn't and NO it can't.

The laws of mathmatics say there is only ONE way this sum should be read.

it's still written in a completeley stupid way, if the BODMAS principle is used then there's no point in using brackets at all, but if brackets are going to be used they should make the sum as clear as possible in this case.

(132x23x43)+6-(4x7x3)

 

[Weezle]

130,590 for me!

132 X (23 X 43) + 6 - 4 X (7 X3)

becomes

132 x 989 + (2 x 21)

130,548 + 42


130,590

 

[eaglejez]

for heavens sake - it is 130,470 and you don't need the brackets. If I'm wrong I will wear a Brighton shirt at the next Palace match

 

[Rangdo]

Keyed it into a calculator that lets you enter the whole sum before pressing "=" and it gives 130,470. Case closed

 

[Commander]

f***ing hell. I sit there bored out of my brain at work, think it would be mildly amusing to ask the insider a maths question, and this is the response.

The answer is 130,470. Case closed.

Now can we all point and laugh at Stumpy Tim and Desperatfan3 who actually PM'd me the WRONG answer!

Anyway, seeing as you are all so interested in my brilliant questions, here is another one:

100 X (45/2) + 31 X (2X3) X 4 X (3x5) + =

 

[larus]

Lets clear this up once and for all. If the question was ;

Whats 132 X (23 X 43) + (6 - 4) X (7 X 3) =, then the brackets are important, as the 6-4 takes precedence over the X (7 X 3). In this case the answer is :

132 X 23 X 43     = 130548 +
(6 - 4) X (7 X 3) = 42
                  = 130590

However, the question was not this, the correct answer as has been clearly explained is 130470, and the brackets in the question are totally irrelevant, as they have no effect on the sequence of the calculations.

to this question as asked by Commander to the insider HERE


I believe the INSIDER is WRONG.




What do you make the answer?

The Insider is right.

 

[Race]

132 X (23 X 43) + 6 - 4 X (7 X3)

then 23X43 =989

and 7X3= 21

therefore
132X989+6-4X21= 2741550

Always always 'do' the calcs in brackets first and then sub the value back in. Doing calcs is like reading abook .. from the left.

I must get a life

correct

Anyway, seeing as you are all so interested in my brilliant questions, here is another one:

100 X (45/2) + 31 X (2X3) X 4 X (3x5) + =

Excel, she say ...

=SUM(100*(45/2)+31*(2*3)*4*(3*5)) = 13410

 

[Rangdo]

Anyway, seeing as you are all so interested in my brilliant questions, here is another one:

100 X (45/2) + 31 X (2X3) X 4 X (3x5) + =

It's not a valid sum due to the extra plus sign at the end.

 

[Bad Ash]

The answer is not 821160 before anyone starts...

 

[Commander]

It's not a valid sum due to the extra plus sign at the end.

That was a typing error, smart-arse

 

[dougdeep]

Just between you and me. I don't care what the answer is.
