Boolean values:
Meaning of Eq a and Ord a: the a may be replaced with almost any type, but they cannot be replaced with function types, for example.
Those are of the same precedence, but they are weaker than the previously introduced operators.
Those operators are not associative.
Therefore it is invalid to place such operators after each other. For example, both a == b == c and a < b > c are invalid expressions.
Make a conclusion on the result:
Write an expression that is True if and only if 23 does not divide 532253373.
The Boolean AND has higher precedence than the Boolean OR and both of them have lower precedence than the previously described operators.
Write an expression clearly demonstrating that the (&&) is stronger than the (||).
