一、算式：
1:(10 × (8 - 6)) + 4
2:10 × (8 - 6) + 4
3:(10 - 6) × 4 + 8
4:((10 - 6) × 4) + 8
5:8 + (10 - 6) × 4
6:8 + ((10 - 6) × 4)
7:8 - (6 - 10) × 4
8:8 - ((6 - 10) × 4)
9:(8 - 6) × 10 + 4
10:((8 - 6) × 10) + 4
11:8 + (4 × (10 - 6))
12:8 + 4 ×(10 - 6)
13:8 - (4 × (6 - 10))
14:8 - 4 ×(6 - 10)
15:4 + (10 × (8 - 6))
16:4 + 10 ×(8 - 6)
17:4 - (10 × (6 - 8))
18:4 - 10 ×(6 - 8)
19:(4 × (10 - 6)) + 8
20:4 × (10 - 6) + 8
21:4 + (8 - 6) × 10
22:4 + ((8 - 6) × 10)
23:4 - (6 - 8) × 10
24:4 - ((6 - 8) × 10)
二、其实上面的算式本质就2种,一种是“4+20”型,一种是“8+16”型
