Answer 1

10-18:(4+12:6)=
10-18:(4+ 2)=
10-18:6=
10-3=7

124 - 2 x [150x(4+16)] : 60 =
124 - 2 x (150x20) : 60=
124 - 2 x 3000 : 60=
124-6000:60=
124-100=4

16x50:[1180-(265+ 5x175)]:2=
800:[1180-(265+875)]:2
800:(1180-1140):2=
800:40:2=
20:2=10

Answer 2

a. 10-18:(4+12:6)=7
=10-18:(4+2)
=10-18:6
=10-3
=7

b.124-2x[150x(4+16)]:60=10
=124-2x(150x20)]:60
=124-2x3000:60
=124-6000:60
=124-100
=24

c.16x50:[1180-(265+5x175)]:2=10
=800:[1180-(265+875)]:2
=800:(1180-1140):2
=800:40:2
=20:2
=10
