doh!
Isn't everything?Looks like the answer is disputed across the t'internet...
There can only be one answer though!
Looked at the answer on internet - I disagree with it surely it is BIDMAS A before S
I'm not sure I got this correct.
However what I did learn in maths was how to write BOOBLESS and BOOBIES on a calculator, which I would say is much more helpful in real life than being able to work this sum out.

(Please don't post the answer in the thread)
How many people will get this right?
199 people have responded, and 37% are correct.
This seems to be continually falling from an early 60%ish being correct.
Got enough answers yet?How many people will get this right?
A and S means A OR S. if you are left with a subraction THEN an addition, you just calculate left to right, you don't do the addition first. This is the reason people are disputing it, because they are WRONG.
I cannot answer this as I believe that more than 7 people will get this right, there is no option for this
if you think of subtraction as just the addition of negative numbers, ie. 5 - 3 is 5 + (-3), it doesnt matter what order it is done in as addition is associative. eg. 1 - 2 + 3 = 1 + (-2) + 3 = 2 whether you do the 1 + (-2) first or the (-2)+3 first. similarly division can be thought of as multiplication by a fraction, ie. 4/2 = 4 x (1/2) = 2, and a similar thing applies. so when it comes to BODMAS it could easily have been BOMDAS or BOMDSA or BODMSA, but BODMAS probably sounded better.
