#1 
e1.or(e2).and(e3)) 

creates at first an 'or' operation based on e1 and e2 and uses this 'or' operation 
in a top level 'and' operation with e3 as the second operand.

Since 'and' has higher precedence than 'or' it is serialized as

(e1 or e2) and e3


#2 
e1.or(e2).and(e3.or(e4)))

'and' is the top level operation and e1.or(e2) and e3.or(e4) are the lower level operations

It is serialized as

(e1 or e2) and (e3 or e4)


#3
e1.and(e2).or(e3.and(a4))

`or`is the top level operation and e1.and(e2) and e3.and(e4) are the lower level operations

It is serialized as

e1 and e2 or e3 and e4

@SeongEon-Jo That's OK. AND has higher priority than OR, so "e1 and e2 and (e3 and e4 or e5)" means that "e3 and e4" will be evaluated first, then "... or e5" and then it's all AND-ed. Just the redundant parentheses are removed. It will work the same.

@virgo47 Oh, I got it. Thanks!
