Thank you for the opportunity to help you with your question!

1.  32 - 212 = - 180

2.  19 - ( -12) = 19 + 12 = 31

3.  - 201 - ( - 42) = - 201 + 42 = - 159

9. - 17 - 8 = - 25

10.  - 9 - ( - 6) = - 9 + 6 = - 3

11.  2.9 - 3.8 = - 0.9

if numbers have same sign add and sing of number 

if numbers have opposite sign subtract smaller from larger and sign of larger
