2+2 first because P. That’s 4.

P is 2(2+2)=(2x2+2x2)=(4+4)=8

Then 8/2 because it’s left of 4(4).

If you do 8/2 when you still have brackets, then you just did division before brackets and disobeyed order of operations rules. You also broke the rule of Terms, since 2(4) is a single term.

Don’t take my word for it.

I see you didn't read my thread then. I have a section on calculators, which points out that WolframAlpha does it wrong. i.e. they also break the rule of Terms.
