Answer 1

Step-by-step explanation:

(a) 37*(-58)+(-58)×(-27)

= -58(37-27)

=-58(10)

= -580

(b) (-45)×103

= -4635

(c) 4×87×(-25)

= 345×(-25)

= -8700

(d) 19×(-25)×(-4)×-8

= 19×100×-8

= 100×19×(-10+2)

=100{(19×-10)+(19×2)}

= 100×(-190+38)

=100×-152

=-15200

(e) (-16)×(-39)

=624

(f) (-68)×(-19)+68

= (-68×(-1)×(-19)+68×1)

= 68(-19×-1+1)

=68(19+1)

=68×20

= 1360
