小学四年算24点的技巧1.2.2.7

解法如下: (1)2×2×(7-1)=24 (2)2×(7-1)×2=24 (3)(7-1)×2×2=24 (4)(2+2)×(7-1)=24 (5)(7-1)×(2+2)=24

1, 2, 4, 7的24点答案: 1: (1 - 2 + 7) × 4 2: ((1 - 2) + 7) × 4 3: (1 - (2 - 7)) × 4 4: (1 + 4 + 7) × 2 5: ((1 + 4) + 7) × 2 6: (1 + (4 + 7)) × 2 7: (1 + 7 - 2) × 4 8: ((1 + 7) - 2) × 4 9: (1 + (7 - 2)) × 4 10: (1 + 7 + 4) × 2 1...

(7-2+1)X4=24

(2+2)×(7-1)=24 2×2×(7-1)=24

4*(7+1-2)=24 2*(1+4+7)=24
