Answer 2

1) (+16)-(+20)= 16 - 20 = -4
2) (+12)-(+20)= 12-20= -8
3)(+15)-(+25)= 15-25= - 10
4) (-21)+(-12)= -21-12= -33
5) (-39)+(-11) = -39-11= - 50
6) (- 20) +(+60) = -20+60= 40
7) (+20)+(-8)= 20-8= 12
8)(+30) + (-50)= 30 - 50= -20
9)(+27)+(-19)= 27 - 19= 8
10)(-32)-(-22)= -32 + 22= -10
11) (+16)-(-10)= 16+10=26
