Question

a, ( 2354- 45 ) - 2354

b, ( 16 + 23 ) + ( 153 - 16 - 23 )

c, -3752 - ( 29 -  3632 ) - 51

Answer 1

a, 

= 2354 - 45 - 2354 

= -45

b, 

= 16 + 23 + 153 - 16 - 23

= 153

c, 

= -3752 - 29 + 3632 - 51

= ( 3632 - 3752 ) - ( 29 + 51 )

= -120 - 80

= -200

Answer 2

a, 

= 2354 - 45 - 2354 

= -45

b, 

= 16 + 23 + 153 - 16 - 23

= 153

c, 

= -3752 - 29 + 3632 - 51

= ( 3632 - 3752 ) - ( 29 + 51 )

= -120 - 80

= -200
