Answer 1

a )-9-(-6)+8= -9 + 6 + 8 = 5

b)+6-(-4)+10= 6 + 4 + 10 =20

c) +12-(-9)-2= 12 + 9 -2 = 19

d)+6-(-4)+10= 6 + 4 +10 = 20

e)-21-(+17)-(-2)= -21 -17 +2 = -36

f)0-(-8)-(+8)= 0 + 8 -8 = 0

g)+11-(-9)-(+5)= 11 +9 - 5 = 15

h)4-(+3)+(-7)= 4 - 3-7 =  4- 10 = - 6

i) 0-(+9)+(-9)= 0 - 9 -9= -18

j)-6-[(-4)-(-5)]= 6 -( -4 +5 ) = 6 - 1  = 5

k)-4-[(+10)+3]= -4 -13 = -17

l)-[9-(-9)]-5= - ( 9+9 ) -5 = -18 -5 = -23
