- 'A + B' means 'A is the daughter of B'.
- 'A $\div$ B' means 'A is the father of B'.
- 'A x B' means 'A is the wife of B'.
- 'A - B' means 'A is the brother of B'.

- D + F: According to the rule 'A + B', D is the daughter of F. So, D is female.
- F $\div$ G: According to the rule 'A $\div$ B', F is the father of G. Since D is F's daughter, G is D's sibling.
- G x H: According to the rule 'A x B', G is the wife of H. Since G is F's child and is female, G is D's sister. H is G's husband, making H D's brother-in-law.
