用4个数字:3 3 7 7 用加减乘除四种运算方法算24 !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

(3+3/7)*7

我是试过了，上面的(3+3/7)*7 这种做法，不能做的！！！！！你看看你有没有出错！！！！！！！

1: (3 + 3 ÷ 7) × 7
2: (3 + (3 ÷ 7)) × 7
3: (3 ÷ 7 + 3) × 7
4: ((3 ÷ 7) + 3) × 7
5: 7 × (3 + 3 ÷ 7)
6: 7 × (3 + (3 ÷ 7))
7: 7 × (3 ÷ 7 + 3)
8: 7 × ((3 ÷ 7) + 3)
够了吗，呵呵！

[3 + (3 ÷ 7)] × 7 =24

弄半天还是只有一种答案啊

1: (3 + 3 ÷ 7) × 7
2: (3 ÷ 7 + 3) × 7
3: 7 × (3 + 3 ÷ 7)
4: 7 × (3 ÷ 7 + 3)
