In Athey maths Paper 2 :
8+6+7-2+9-1= ...
According to my knowledge of maths learned abroad it is 9.
I noticed that in my son's school they seem to ignore the basic maths rules, therefore according to what he would have learned in school the result would be 27.
There cannot be 2 different result of the same simple equasion for goodness sake!
I do not have the answer sheet re the above Athey' test therefore do not know what result is suggested by them . Could someone enlighten me please.

Jah,
Your answer is incorrect - the correct mathematical answer is 9. I agree with with Moose.
This type of issue came up last year and we had a long debate about it. The problem is that mathematically you should use BIDMAS to answer the question correctly from a mathermatical point of view - BUT childen are not taught BIDMAS as part of KS1 or KS2. So schools tell children to just work it out from left resulting in an incorrect answer.
I think we concluded that in an formal 11+ exam we would hope that the question would be unambiguous by the inclusion of brackets.
From a mathematical point of view 27 cannot be the answer.
Hope this helps

I repeat as well, there is no bracket, division or multiplication in the above sum. The answer 27 is correct as its a simple addition & subtraction which can be done in any order..........In Athey maths Paper 2 :
8+6+7-2+9-1= ...
I do not agree with answer 9, unless there is some misprint......
