①4，4，7，7
================
(4-4÷7)×7 = 24
(4-(4÷7))×7 = 24
================
7×(4-4÷7) = 24
7×(4-(4÷7)) = 24
================

②4，4，5，5
================
(4+4÷5)×5 = 24
(4+(4÷5))×5 = 24
================
4×(5-4+5) = 24
4×((5-4)+5) = 24
4×(5-(4-5)) = 24
(4÷5+4)×5 = 24
((4÷5)+4)×5 = 24
================
4×(5+5-4) = 24
4×(5+(5-4)) = 24
4×((5+5)-4) = 24
================
5×(4+4÷5) = 24
5×(4+(4÷5)) = 24
================
(5-4+5)×4 = 24
((5-4)+5)×4 = 24
(5-(4-5))×4 = 24
5×(4÷5+4) = 24
5×((4÷5)+4) = 24
================
(5+5-4)×4 = 24
(5+(5-4))×4 = 24
((5+5)-4)×4 = 24
5×5-4÷4 = 24
(5×5)-4÷4 = 24
5×5-(4÷4) = 24
(5×5)-(4÷4) = 24
================
