From what a few people have said - take the question in context of an 11+ exam I have the following thoughts on that:

Yes it is an 11+ exam.
In the sciences, they teach you about things that you need to know for your level. This is very apparent at GCSE/A level in the sciences.

Generally speaking, as long as the answer you provide is correct (I.e if your answer isn't on the syllabus, but is correct as you have gone into more detail or further, you will still be awarded the marks)

They will never set a question, where the answer is completely wrong.

The answer to the question above can never be 5. They would not teach children that the answer should be 5.

Either, operator precedence should be taken off the syllabus and not tested, or it should be tought properly.

DB's no1 son:

7-3#looks in head#..........seven.......duuuh thas easy.

So, the 9 year olds first answer is seven. I didn't give him the option 5 or 7. Just asked him to give me the answer to the equation.
He said thats how hes been taught at school. He doesn't know another way, so therefore 5 was not an option anyway

I came out at 7 and it took me quite some time to see how anyone could arrive at 5.

Never heard of BODMAS either. I pretty much worked it out as DB's first post.

7-3 = 4
6 / 2 = 3

4 + 3= 7

Brackets always first as per bodmas (not that I can remember many more of the letters), it's not written in the plainest way though, in the text book/exam was it set out differently?

Blimey this post has grown since original post. Didn't expect tso many to get it wrong.

There are no two ways about it. It is 7. No ifs or buts'.

Google (7-3)+6÷2

Seeeee lol.

It also makes it neater for you with a second set of brackets. However with or without brackets the answer is still 7.

This thread is madness. 33 people are essentially arguing that 2x2 is 5?
