answer

1、(-20)-(-3)÷ㄧ-9ㄧ+2×(-5)

=(-20)-(- 1/3)+(- 10)

=-89/3

2、23+|-7 |÷X3(- 1/2 1)

=23+(- 147)-(- 15)

=- 109

3 、(-30)-(20)÷5+(-6)X(- 1/2)

=-30 - 4+3

=-23

4 、|- 12 | X(- 1/2)-(-8)X(-5)+30

=-6-40+30

=- 16

5 、(-7)X(-2)÷(- 1)-|8|

= 14÷- 1-8

-22

6 、|-20 |-2 X(- 1/5)X3

=- 10X- 1/5X3

=6

7 、(-50)-(-8)X|-6|÷ 1/3

=-50-48 divided by 1/3

=-50 - 144

=94

8、56÷(- 1/5)÷ 1/20+| 3x 1-2 |

=-280 divided by 1/20+ 1

=-5599

9、7+(-22)÷ 1/2-(-5)X7

=7+-44 - 35

=-2

10、 8 1÷(- 1/9)÷| 1/3|-(-2)

=-729÷ 1/3+2

=-2 187+2

=-2 185
