Question

1.a) 9×(8+2)= b)5×(6-7)= c)7×(-1+3)=

d)-4×(3-2)= e)(17-5)×(+2)= f)(-8-3)×(-1)=

g)(-10)×(4-7)= h)(-20)×(10+6)=

Answer 1

a) 9×(8+2)= 9 . 10 = 90
b)5×(6-7)=   5 . -1  =   -5
c)7×(-1+3)= 7 . +2 =   14
d)-4×(3-2)= -4 .1   =    -4 
e)(17-5)×(+2)= 12 . 2 = 24
f)(-8-3)×(-1)= -11 . -1 = +11
g)(-10)×(4-7)= -10 . -3 = +30
h)(-20)×(10+6)= -20 . 16 = - 320
