Answer 2

Jawaban:

2. a) 6 x( -2)= -12 +-3= -15

b) (-8):2= -4 x 4= -16

c) 4 + (-5)= -1 x 6= -6

d) [ -40 : (3+5)]= -40 : 8= -5 x 8= -40

e) [(16-6) x (-5)]= 10 x -5= -50:150=-3

f) [-60:(16-4)]= -60 : 12= -5

(-4-6)= -10= -10 x -5= 50

3. a) (i). (5 x 4)= 20 x (-3)= -60

(4 x (-3))= -12

(ii). (6 x (-2))= -12 x 7= -84

((-2) x 7)= -14 x 6= -84

(iii). (8 x(-6))= -48 x (-5)= 240

((-6)x(-5))=30 x 8= 240

(iv). ((-7) x (-9))=63 x (-4)= -252

((-9)x(-4))=36 x (-7)= -252

4. a).48:6=8

b).-72:6=-12

c).(-52):(-13)=4

d).144:(-4)= -36

e).(-2)x(-7)=14

84:14=6

5. a.120+(-8)=188

b.100+(-12)=88

c.40-15=25

d.20-28= -8
