Order of operations - what is 6÷2(1+2) ?

[Paul Berger (Canada)]

I just tried the 6/2(1+2) on my prime which was in textbook mode and it entered this as a fraction with with 6 on the top and 2(1+2) on the bottom so naturally the answer it get is 1, I then changed the entry mode to algebraic and it entered as 6/2(1+2) and gave me 9 as the answer.
