a) 4 12 -18 -8
b) -13 -6 -6 -9
c) 22 0 -84 -82
d) 60 -190 540 90
(-3)-(-7)=-3+7=4
8-(-4)=8+4=12
(-10)-8= -18
7-15= -8
(-3)-10= -13
(-12)-(-6)=(-12)+6= -6
(-9)-(-3)=(-9)+3= -6
(-8)-1= -9
11-(-11)=11+11= 22
(-25)-(-25)=-25+25= 0
(-34)-50= -84
(-42)-40= -82
(40)-(-20)=40+20= 60
(-120)-70= -190
520-(-20)=520+20= 540
(-110)-(-200)=-110+200= 90
