In a certain coded language: 'A * B' means 'A is the brother of B' 'A > B' means 'A is the wife of B' 'A = B' means 'A is the father of B' 'A $ B' means 'A is the sister of B' Based on this information, if the expression is 'A $ D $ M > I = N', how is A related to N?

In a certain code language: 'A + B' means 'A is the sister of B' 'A - B' means 'A is the brother of B' 'A × B' means 'A is the wife of B' 'A ÷ B' means 'A is the father of B' Based on the above, how is M related to R if 'M + K ÷ L - P × R'?

In a certain code language: 'A # B' means 'A is the mother of B', 'A + B' means 'A is the daughter of B', 'A ÷ B' means 'A is the wife of B', and 'A @ B' means 'A is the father of B'. How is A related to T if 'A + B # H @ K ÷ T'?
