7,1,11,3:没有答案.

12除以（12-9）乘以6

1
8/(3-3/8)
2
6/(1-3/4)
3
12*(9-6)-12
12*(6+12)/9
12*(6+12)/9
是不是13/(7-1)*11约等于24???

1.8/(3-8/3)
2.
解1 6/(1-3/4)
3.
解1 12*(9-6)-12
解2 6*12/(12-9)
解3 12*(6+12)/9
4. 7。1。11。3 无解

6/(1-3/4)
6/(1-(3/4))
(12+6)*12/9
(12+6)*(12/9)
((12+6)*12)/9
(12+6)*12/9
(12+6)*(12/9)
((12+6)*12)/9
(6+12)*12/9
(6+12)*(12/9)
((6+12)*12)/9
(6+12)*12/9
