CASIO calculators say 1, and I think it’s more intuitive with “÷2π” being equivalent to “÷(2×π)” rather than “÷2×π”. It took me a while to figure out why my results were almost but not quite one order of magnitude wrong after I was forced to switch to TI. Obviously nobody in high school or uni wrote ÷ (or Czech :) on paper, it was all fractions, but even on “natural mode” calculators I’d use the ÷ key for simple denominators to save vertical space.
my calculator disagrees.
and i would too, this is basically
6÷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 did
6÷(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

Incorrect. Multiplication and division happen in whichever order they appear left to right. They have the same priority.
Who taught you that? They shouldnt have.
