a) -56 - ( 47 - 56 ) + 33

= -56 - 47 + 56 + 33

= ( -56 + 56 ) - ( 47 - 33 )

= -14

b) 168 + ( 35 - 68 ) - 35

= 168 + 35 - 68 - 35

= ( 168 - 68 ) + ( 35 - 35 )

= 100

a, -56 - ( 47 - 56 ) + 33

= - 56 - 47 + 56 + 33

= - 103 + 56 + 33

= -47 + 33 = -14

a) \(33\times4+5\times33+33\times3+33-99=33\times4+5\times33+33\times3+33\times1-33\times3\)

\(=33\times\left(4+5+3+1-3\right)=33\times10=330\)

b) \(256+347+453-147-56-253=\left(256-56\right)+\left(347-147\right)+\left(453-253\right)\)

\(=200+200+200=600\)

127.(27 - 56) - 27.(127 - 56)

= 127.27 - 127.56 - 27.127 + 27.56

= (127.27 - 27.127) - (127.56 - 27.56)

= 0 - 56(127 - 27)

= 0 - 56.100

= 0 - 5600

= -5600

127.(27-56)- 27 . (127 - 56)
