Answer 1

A: -3+3=0
B: 32-21= 11
C: 1+28= 29
D: 3+14=17

Answer 2

A)
= - (- 6) + (- 9) - (- 3)= 6 - 9 + 3
= 6 + 3 - 9
= 9 - 9
= 0

*****************************
B)
= +(+19)-(-13)+(-21)
= 19 + 13 - 21
= 32 - 21
= 11

****************************
C)
= +(-14)+(+15)-(-28)
= - 14 + 15 + 28
= 1 + 28
= 29

*******************************
D)
= +(+9)+(-6)-(-14)
= 9 - 6 + 14
= 3 + 14
= 17

*****************************
E)
= -(+21)+(-6)-(-17)
= - 21 - 6 + 17
= - 27 + 17
= - 10

*******************************
F)
= +(+14)-(-21)+(+22)
= 14 + 21 + 22
= 35 + 22
= 57

**************************************
G)
= +(+20)-(-12)+(+31)
= 20 + 12 + 31
= 32 + 31
= 63

*****************************
H)
= - (+16)+(+9)-(-8)
= - 16 + 9 + 8
= - 16 + 17
= 17 - 16
= 1

*******************************
I)
= -(+6)-(-9)+(+10)
= - 6 + 9 + 10
= - 6 + 19
= 13

*******************************
j)
= +(-6)-(+4)+(+25)
= - 6 - 4 + 25
= - 10 + 25
= 25 - 10
= 15

******************************
K)
= +(+31)-(+28)-(+19)
= 31 - 28 - 19
= 3 - 19
= - 16

L)
= +(-12)-(+13)-(-13)
= - 12 - 13 + 13
= - 12 + 0
= - 12
