7，3，3，7按顺序算24点

1: 7 × (3 + 3 ÷ 7)
2: 7 × (3 + (3 ÷ 7))
3: 7 × (3 ÷ 7 + 3)
4: 7 × ((3 ÷ 7) + 3)
5: (3 ÷ 7 + 3) × 7
6: ((3 ÷ 7) + 3) × 7
7: (3 + 3 ÷ 7) × 7
8: (3 + (3 ÷ 7)) × 7

1: 7 × (3 ÷ 7 + 3)
2: 7 × ((3 ÷ 7) + 3)
3: 7 × (3 + 3 ÷ 7)
4: 7 × (3 + (3 ÷ 7))
5: (3 ÷ 7 + 3) × 7
6: ((3 ÷ 7) + 3) × 7
7: (3 + 3 ÷ 7) × 7
8: (3 + (3 ÷ 7)) × 7

7*（3+（3/7））=24；
7*（（3/7）+3）=24；

LZ加分

7*(3+3/7)=24
7*(3/7+3)=24
