(1) (a) 9- 4= 9+ (-4)
(b) 7-(-3) = 7 + 3
(c) 8 – (-15) = 8+15
(d) -7 -9 = -7+ (-9)
(e) -7-(-4) = 7+4
(f) 20-14 = 20+(-14)
(2) (a) 15-8 = 7
(b) 8- (-3) = 8+3= 11
(c) 16- (-5) = 16+5 = 21
(d) 12 -17 = -5
(e) -7-4 = -11
(f) -18-6 = -24
(g) 17- (-19) = 17+19 = 36
(h) 20-4 = 16
(i) 8- (-8) = 8 + 8 = 16
(j) – 7 – (-27) = -7 + 27= 20
(k) -60-(-8) = – 60 + 8 = -52
(3) (a) -200- (-300)
= -200 + 300
= 100
(b) -10-270
= -280
(c) -5 -7985
= -280
(d) -2009 – 0
= -2009
(e) 0 – (-275)
= 275
(f) -3920- (-2910)
= -3920+ 2910
= -1010
(4) (a) 6- (-2) > 7 – 5
(b) -2 – (-8) < 7- (-3)
(c) -7+ (-10) < -7- (10)
(d) (-15) – (-15) > -15 – 15
(5) (a) Therefore, other integer = 50- (-30)
= 50+30
= 80
(b) Therefore, other integer = -567- 33
= -600
