Answer 2

27 x 49 + 27 x 52 - 27

= 27 x (49 + 52 - 1)

= 27 x 100

= 2700

2448 : [119 - (23-6)]

= 2448 : (119 - 17)

= 2448 : 102

= 24

(2736 - 75) - 2736

= (2736 - 2736) - 75

= 0 - 75

= -75

Answer 3

 27x49+27x52-27

=27x49+27x52-27x1

=27x(49+52-1)

=27x100

=2700

 2448:[119-(23-6)]

=2448:[119-17]

=2448:102

=24

 (2736-75)-2736

=2736-2736-75

=0-75

=-75
