减去5655即可

6+(7-5)*96+((7-5)*9)6+9*(7-5)6+(9*(7-5))6-(5-7)*9(7-5)*9+66-9*(5-7)9*(7-5)+6不变位置无解

1: 6 - (5 - 7) * 9 2: 6 - ((5 - 7) * 9) 3: 6 + (7 - 5) * 9 4: 6 + ((7 - 5) * 9) 5: 6 - (9 * (5 - 7)) 6: 6 - 9 *(5 - 7) 7: 6 + (9 * (7 - 5)) 8: 6 + 9 *(7 - 5) 9: (7 - 5) * 9 + 6 10: ((7 - 5) * 9) + 6 11: (9 * (7 - 5)) + 6

6-(5-7)*9=24

(7-5)x9+6

(7-5)*9+6=24(7+6-5)*√9=24[(9-5)*(7-6)]!=4!=24

(7-5)*9+6=18+6=24

(7-5)x9+6=24------------------------------- ---------------

(7-5)*9+6=24

(7-5)乘以9+8
