Yes. I am well aware. 6 ÷ 2 * (2+1) = (2+1) * 6 ÷ 2 = (6 * (2+1))÷2 = 6 * (2+1) ÷ 2

What he wanted to do is 6 ÷ (2 * (2+1))

But this just comes down to if you treat 2(2+1) as one or two expressions.

And honestly, i don’t blame anyone for thinking one way or the other. Because i think most people understand that we wanted to write (2(2+1)), just that the overall parentheses is implied
