用2,4,5,8算24点

1、常规运算: (5+8)*2-2 2、特殊运算: (8-5+2/2)!=4!=4*3*2*1=24

共6种不同算法,举例如下: 2×(4×5-8)=24 4×2×(8-5)=24

8*(4*2-5) =8*(8-5) =8*3 =24; (8-5)*4*2 =3*4*2 =12*2 =24; 4*5+8/2 =20+4 =24; 8*(5-4+2) =8*3 =24; 8*5/2+4 =40/2+4 =20+4 =24; ……

2*4+8+8=24; (2-8)*(4-8)=24; 2*(8-4+8)=24; (4-2)*8+8=24; 4/2*8+8=24; (8-4)*(8-2)=24; 8-8*(2-4)=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 × ((...

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

多种算法,举例如下: 6÷(4-2)×8=24 6÷4×2×8=24

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

共三种不同算法,举例如下: 8÷(2-5÷3)=24 2×(5+3)+8=24

(5+7)*4/2
