We have this discussion almost daily, with almost the same numbers.....the issue is : You question, as written, is AMBIGUOUS.....it depends on what you MEAN......MOST calculators will interpret your question as meaning
(6/2) x (1+2)
BUT you may find a very few that inerpret your input (as written) as
6 / (2 x (1+2) )
Most of us here, and the calculators agree, that as you have it written it is interpreted as the former NOT the latter !!!
And I can use BOLDFACE TYPE AND COLOR.....
