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 kind regards --botp Andreas
