5.6.7.8和6.7.8.9怎么算24点

Answer 1

下面结果是我的程序利用穷举方法运行出来的结果：
5、6、7、8：
((5-6)/8)-7 = 24
(5+(7-8))*6 = 24
((5+7)-8)*6 = 24
((5+7-8)*6) = 24
(5+7)*(8-6) = 24
((5*7)/8)*6 = 24
((5*7/8)*6) = 24
((5-8)+7)*6 = 24
((5-8+7)*6) = 24
(5-(8-7))*6 = 24
(5-(8/7))*6 = 24
((5-8/7)*6) = 24
(6-(5*7))*8 = 24
((6-5*7)*8) = 24
(6*(5+7-8)) = 24
6*((5+7)-8) = 24
6*(5+(7-8)) = 24
(6*(5*7/8)) = 24
6*((5*7)/8) = 24
(6*(5-8+7)) = 24
6*((5-8)+7) = 24
6*(5-(8-7)) = 24
(6*(5-8/7)) = 24
6*(5-(8/7)) = 24
(6-(7*5))*8 = 24
((6-7*5)*8) = 24
(6*(7+5-8)) = 24
6*((7+5)-8) = 24
6*(7+(5-8)) = 24
(6*(7*5/8)) = 24
6*((7*5)/8) = 24
(6/(7-5))*8 = 24
(6/(7-5)*8) = 24
(6*(7-8+5)) = 24
6*((7-8)+5) = 24
6*(7-(8-5)) = 24
(6*8)/(7-5) = 24
6*(8/(7-5)) = 24
(7+(5-8))*6 = 24
((7+5)-8)*6 = 24
((7+5-8)*6) = 24
(7+5)*(8-6) = 24
((7*5)/8)*6 = 24
((7*5/8)*6) = 24
((7-8)+5)*6 = 24
((7-8+5)*6) = 24
(7-(8-5))*6 = 24
(8-6)*(5+7) = 24
(8*(6-5*7)) = 24
8*(6-(5*7)) = 24
(8-6)*(7+5) = 24
(8*(6-7*5)) = 24
8*(6-(7*5)) = 24
(8*6)/(7-5) = 24
8*(6/(7-5)) = 24
(8/(7-5))*6 = 24
(8/(7-5)*6) = 24

6、7、8、9：
(6-(9*7))/8 = 24
((6-9*7)/8) = 24
(6/(9-7))*8 = 24
(6/(9-7)*8) = 24
((6-9)/8)-7 = 24
(6-(7*9))/8 = 24
((6-7*9)/8) = 24
(6*8)/(9-7) = 24
6*(8/(9-7)) = 24
(8/(9-7))*6 = 24
(8/(9-7)*6) = 24
(8*6)/(9-7) = 24
8*(6/(9-7)) = 24
(8-(6*7))/9 = 24
((8-6*7)/9) = 24
(8-(7*6))/9 = 24
((8-7*6)/9) = 24

Answer 2

6÷（7-5）×8=24
（5+7-8）×6=24

6÷（9-7）×8=24
8÷（9-7）×6=24

Answer 3

6÷（7-5）×8=24
（5+7-8）×6=24

6÷（9-7）×8=24
8÷（9-7）×6=24

Answer 4

(7+5)*(8-6)=24/(8×6)÷(9-7)=24

Answer 5

(7+5)*(8-6)=24
