a) (-3).(-8)+(-2).(-6)=
B)(+4).(-5)-(+2).(-7)=
C)10+2.(-3).(-5).(-4)=
d)-(+5).(-1)+10-4-(-7)=
e)(28-2)-(15+10)-6=
f)(-9+2)+(1+2+7-8)=
g) 15-(-6+8)-(-1+2+7-8)=

Answer 1

a) (-3).(-8)+(-2).(-6)
(-24) + (-12)
-24 -12
R= -36

b) (+4).(-5)-(+2).(-7)
(-20) - (-14)
-20 + 14
R= 6

c) 10+2.(-3).(-5).(-4)
12. (-15).(-4)
12. (-60)
R= 720

d) -(+5).(-1)+10(-4)-(-7)
-5.(-1)+10(-4)+7
32-4
R= 28

e) (28-2)-(15+10)-6
26-5-6
26-11
R= 15

f) (-9+2)+(1+2+7-8)
-7+2
R= 5

g) 15-(6+8)-(-1+2+7-8)
15-4
R= 11
