Infixed notation means that the operator comes between the operands, for example 1 + 1 . Functions in haskell generally use postfixed notation, such as pow 1 2 .

r or l refers to associativity, r to right associativity

In your example True && True && True will be interpreted as True && (True && True)

The number refers to precedence, the greater the number, the greater the precedence.
