BEDMAS? 2006-11-29
From john:
I won a contest and they have a confusing format for the STQ. here it is:
11 (+) 44 (x) 2 (-) 10 (%) 25
I've never seen brackets around the operands and wondering how to treat it. I fear they want me to answer the question left to right as the answer is 4 if I use BEDMAS I get 98.6 (which clearly sounds wrong for what they want)
any thoughts?
