b) (-8) . 72 + 8 . (-19)- (-8)

c)  28 +(19 - 28 ) - ( 32 - 57)

d) 101 + (- 60) + 29 + (- 40)

Answer 1

a: =19x41+41=820

Answer 2

a.19.41+41=41.20=820

Answer 3

b.-800-(-8)=-792

Answer 4

c.28+(19-28)-(32-57)=44
d.130+(-100)=30

Answer 5

a) 19 . 25 + 19 . 16 + 41

=19.(25+16)+41

=19.41+41

=820

b)(-8) . 72 + 8 . (-19)- (-8)

=(-8) . 72 + (-8) . 19+8

=(-8).(72+19)+8

=(-720)

c)28 +(19 - 28 ) - ( 32 - 57)

=28+19-28-32+57

=(28-28)+(-32+57+19)

=0+44

=44

d) 101 + (- 60) + 29 + (- 40)

=[(- 60)+(- 40)]+(101+ 29)

=(-100)+130

=30
