两个7两个3怎么算24点

1: 7 * (3 ÷ 7 + 3)2: 7 * ((3 ÷ 7) + 3)3: 7 * (3 + 3 ÷ 7)4: 7 * (3 + (3 ÷ 7))5: (3 ÷ 7 + 3) * 76: ((3 ÷ 7) + 3) * 77: (3 + 3 ÷ 7) * 78: (3 + (3 ÷ 7)) * 7

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

1. 7*[3÷7+3] 2. 7*[3+3÷7] 3. [3÷7+3]*7

解:只有一种计算方法:(3÷7+3)*7=24

8÷(3-8÷3) =8÷(3-8/3) =8÷(9/3-8/3) =8÷1/3 =8*3 =24

7 * (3/7 + 3) = 24

(3÷7+3)*7 =(3/7+3)*7=(3/7+21/7)*7 =24/7*7 =24呵呵,从早上7点到下午3点再到凌晨3点最后到早上7点 ,正好24小时.

(3+3÷7)*7=24

7*(3+3/7)=24
