((3-7)×(5-11))
((5-11)×(3-7))
((7-3)×(11-5))
(((7×11)-5)÷3)

啥意思哟!你把题写清楚嘛,我们就好帮你解决了。

(7-3)*(-5-(-11))=24

(7-3)*[-(-11)-5]=24

1: (3 - 7) × (5 - 11)
2: (5 - 11) × (3 - 7)
3: (11 - 5) × (7 - 3)
4: (11 × 7 - 5) ÷ 3
5: ((11 × 7) - 5) ÷ 3
6: (7 - 3) × (11 - 5)
7: (7 × 11 - 5) ÷ 3
8: ((7 × 11) - 5) ÷ 3

7-3=4
-5-(-11)=6
4X6=24
