1. 2、3、-6、10这4个数且用一次,进行加减乘除,用不同的3种方式求出结果等于24。

2.小亮早晨进行跑步训练,先向南跑1小时40分,再向北跑2小时,然后又向南跑,此时速度由原来的每小时6千米减少到原来的2/3,这样又跑了1.5小时,请问小亮此时在出发点的北边还是南边?距离出发点多远?
3种算式!!!!!!!!!!!!!!!!!!

1:2*3*(-6+10)
(2*3)*(-6+10)
2*[3*(-6+10)]

2:2-5/3=1/3(小时)
1/3*6=2(千米)
6*2/3*1.5=6(千米)
6-2=4(千米)
答:在南边,距离出发地4千米

1: 3 × (3 ÷ 3 + 7)
2: 3 × ((3 ÷ 3) + 7)
3: (3 + 3) × (7 - 3)
4: (3 ÷ 3 + 7) × 3
5: ((3 ÷ 3) + 7) × 3
6: 3 × (7 + 3 ÷ 3)
7: 3 × (7 + (3 ÷ 3))
8: (7 + 3 ÷ 3) × 3
9: (7 + (3 ÷ 3)) × 3
10: (7 - 3) × (3 + 3)

1: (6 × (5 + 3)) ÷ 2
2: 6 × (5 + 3) ÷ 2
3: 6 × ((5 + 3) ÷ 2)
4: 6 × (5 - 3 + 2)
5: 6 × ((5 - 3) + 2)
6: 6 × (5 - (3 - 2))
7: 6 × 5 - 3 × 2
8: (6 × 5) - 3 × 2
9: (6 × (5 - 3)) × 2
10: 6 × (5 - 3) × 2
11: 6 × ((5 - 3) × 2)
12: 6 × 5 -(3 × 2)
13: (6 × 5) - (3 × 2)
14: 6 × (5 + 2 - 3)
15: 6 × ((5 + 2) - 3)
16: 6 × (5 + (2 - 3))
17: 6 × 5 - 2 × 3
18: (6 × 5) - 2 × 3
19: 6 × 5 -(2 × 3)
20: (6 × 5) - (2 × 3)
21: (6 × (3 + 5)) ÷ 2
22: 6 × (3 + 5) ÷
