In a certain code language: ‘A + B’ means ‘A is the mother of B’; Based on the above, how is 4 related to 2 if ‘4 + 3 ÷ 2 ÷ 1 − 5’?
‘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’.
Father’s mother

The relationship sequence deciphers that 4 is the mother of 3, who is the father of 2. Thus, 4 is 2’s Father's Mother.
