有48种算式如下：

1: 7 ÷ 5 × 10 + 10 2: (7 ÷ 5) × 10 + 10 3: (7 ÷ 5 × 10) + 10 4: ((7 ÷ 5) × 10) + 10 5: (7 ÷ (5 ÷ 10)) + 10 6: 7 ÷ (5 ÷ 10) + 10 7: 7 × 10 ÷ 5 + 10 8: (7 × 10) ÷ 5 + 10 9: (7 × 10 ÷ 5) + 10 10: ((7 × 10) ÷ 5) + 10 11: (7 × (10 ÷ 5)) + 10 12: 7 × (10 ÷ 5) + 10 13: 10 ÷ 5 × 7 + 10 14: (10 ÷ 5) × 7 + 10 15: (10 ÷ 5 × 7) + 10 16: ((10 ÷ 5) × 7) + 10 17: (10 ÷ (5 ÷ 7)) + 10 18: 10 ÷ (5 ÷ 7) + 10 19: 10 + 7 ÷ 5 × 10 20: 10 + (7 ÷ 5) × 10 21: 10 + (7 ÷ 5 × 10) 22: 10 + ((7 ÷ 5) × 10) 23: 10 + (7 ÷ (5 ÷ 10)) 24: 10 + 7 ÷(5 ÷ 10) 25: 10 × 7 ÷ 5 + 10 26: (10 × 7) ÷ 5 + 10 27: (10 × 7 ÷ 5) + 10 28: ((10 × 7) ÷ 5) + 10 29: (10 × (7 ÷ 5)) + 10 30: 10 × (7 ÷ 5) + 10 31: 10 + 7 × 10 ÷ 5 32: 10 + (7 × 10) ÷ 5 33: 10 + (7 × 10 ÷ 5) 34: 10 + ((7 × 10) ÷ 5) 35: 10 + (7 × (10 ÷ 5)) 36: 10 + 7 ×(10 ÷ 5) 37: 10 + 10 ÷ 5 × 7 38: 10 + (10 ÷ 5) × 7 39: 10 + (10 ÷ 5 × 7) 40: 10 + ((10 ÷ 5) × 7) 41: 10 + (10 ÷ (5 ÷ 7)) 42: 10 + 10 ÷(5 ÷ 7) 43: 10 + 10 × 7 ÷ 5 44: 10 + (10 × 7) ÷ 5 45: 10 + (10 × 7 ÷ 5) 46: 10 + ((10 × 7) ÷ 5) 47: 10 + (10 × (7 ÷ 5)) 48: 10 + 10 ×(7 ÷ 5)

10除以5=2 2乘7=14 14+10=24

7*10/5+10=24

哈哈.我算出来了.

10除5=2 2乘7=14 14+10=24
