Converse: If x³ - x is divisible by 3, then x is an integer

Inverse: If x is not an integer, then x³ - x is not divisible by 3

Contrapositive: If x³ - x is not divisible by 3, then x is not an integer

Given the statement "if p, then q", then we have the converse, inverse, contrapositive as:

• Converse: If q, then p (reverse)

• Inverse: If not p, then not q (negation)

• Contrapositive: If not q, then not p (reverse and negation)
