Ah, I wasn’t thinking of calculators that let you type in a full expression. When I was in school, only fancy graphing calculators had that feature. A typical scientific calculator didn’t have juxtaposition, so you’d have to enter 6÷2(1+2) as 6÷2×(1+2), and you’d get 9 as the answer because ÷ and × have equal precedence and just go left to right.
I’ve never seen a calculator that had bracket keys but didn’t implement the conventional order of operations.
But anyway, I’m on Team RPN.
my dumb ass reading this: “Team rock paper nscissors”
RTS = rock taper scissors
FPS = frock paper scissors
