3,3,4,5,的24点怎么算

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

例如: (3-2+5)×4=24 (5+3+4)×2=24 (5+3-2)×4=24

((3/3)+5)*4 (3*(4+5))-3 3*(4*(5-3)) (3*4)*(5-3) 3*((5-3)*4) (3*(5-3))*4 (3*(5+4))-3 ((3/3)+5)*4 (3*(4+5))-3 3*(4*(5-3)) (3*4)*(5-3) 3*((5-3)*4) (3*(5-3))*4 (3*(5+4))-3 4*((3/3)+5) 4*(3*(5-3)) (4*3)*(5-3) 4*((3/3)+5) 4*(3*(5-3))...

用3,3,5,7算24点,共有4种算法。 [﹙5×3﹚-7]×3 3×[﹙3×5﹚-7] 3×[﹙5×3﹚-7] [﹙3×5﹚-7]×3

3×8×(5-4) =24×1 =24

(5-3)×4×3

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

3*4*(10/5)=24

3*(5-(4-7)) 3*((5-4)+7) (3+5)*(7-4) 3*((5+7)-4) 3*(5+(7-4)) ((3*4)+5)+7 (3*4)+(5+7) ((3*4)+7)+5 (3*4)+(7+5) 3*(4*(7-5)) (3*4)*(7-5) 3*((7-5)*4) (3*(7-5))*4 3*((7+5)-4) 3*(7+(5-4)) 3*(7-(4-5)) 3*((7-4)+5) 5+((3*4)+7) (5+(3*4))+7...

3X(9-5+4) =3X8 =24
