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
