Question

\"5 7 10 7\"怎么巧算24点？

Answer 1

(7-5)*7+10=24
((7-5)*7)+10=24
7*(7-5)+10=24
(7*(7-5))+10=24
10-(5-7)*7=24
10-((5-7)*7)=24
10-(5-7)*7=24
10-((5-7)*7)=24
10+(7-5)*7=24
10+((7-5)*7)=24
10-7*(5-7)=24
10-(7*(5-7))=24
10+7*(7-5)=24
10+(7*(7-5))=24
10+(7-5)*7=24
10+((7-5)*7)=24
10-7*(5-7)=24
10-(7*(5-7))=24
10+7*(7-5)=24
10+(7*(7-5))=24
(7-5)*7+10=24
((7-5)*7)+10=24
7*(7-5)+10=24
(7*(7-5))+10=24

希望以上答案对楼主有所帮助，另祝楼主好运！
