8,4,7变成24点算式是: 8×(7-4) =8×3 =24

1: (2 + 2) × 4 + 8 2: ((2 + 2) × 4) + 8 3: 2 × 2 × 4 + 8 4: (2 × 2) × 4 + 8 5: (2 × 2 × 4) + 8 6: ((2 × 2) × 4) + 8 7: (2 × (2 × 4)) + 8 8: 2 × (2 × 4) + 8 9: (2 × (2 + 8)) + 4 10: 2 × (2 + 8) + 4 11: 2 × (2 × 8 - 4) 12: 2 × ((...

这就是24点吧!应该是(7-4)乘 8+2 或4乘7-8除以2

(4 - 9 ÷ 9) × 8 =(4-1)×8 =3×8 =24

(6-4)*(8+4)

(5+7)×(10-8) =12×2 =24

设1表示加,2表示减,3表示乘,4表示除,其运算组合是64,如下表所示: 运算 111,112,113,114,121,122,123,124,131,132,133,134,141,142,143,144,211,212,213,214,221,222,223,224,231,232,233,234,241,242,243,...

第一题: (7 - 5) × 8 + 8 =24 (7 + 8) ÷ 5 × 8=24 第二题: 4×(7+1-2)=24 2×(1+4+7)=24 第三题: 4+4+4+12=24 (4+4)÷4×12=24 第四题: 7+5+4×3=24 (7+5)+4×3=24
