Like I say, we were expressly taught that only if the brackets are there, do you calculate those 1st - if they weren't, to do as someone else posted, and calculate left to right. I'm assuming no-one has actually bothered to open the calc on their PC and run through the question using 1st standard, then scientific? Basically, the brackets taught us that the question was meant in one way, and without, the question was meant in another.
Exponents, yes.
