Hi
p(1 and 2 or 3 and 4)
1. how many brackets do we need?

none if you know the order :)

2. in my opinion the result should be 2, not 4.
What do you think?

> 1 and 2 or 3 and 4

=> 4

evaluation left to right

> 1 && 2 || 3 && 4
=> 2

evaluation 1st: 1 && 2 => 2

evaluation 2nd: 3 && 4 => 4

evaluation last: 2 || 4 => 2

"or" and "and" have same priority.
"&&" precedes "||".

check: https://docs.ruby-lang.org/en/master/syntax/precedence_rdoc.html
