my calculator disagrees.
and i would too, this is basically6÷2(1+2) = 6÷2×(1+2) = 6÷2×3
while you resolve brackets first, you still go left to right. you would get 1 if you did6÷(2×(1+2))
the issue is the missing multiplication sign between the 2 and the brackets, thats why i always write them even if it is not strictly required
its never not funny
