Question

2021.( -125 )-178. (-2011)+(- 2021). 53

Answer 1

`2021 . (-125) - 178 . (-2011) + (-2021).53`

`= -2021.125 + (-2021).53 - 178.(-2011)`

`= -2021 (125 + 53) - 178.(-2011)`

`= -2021 . 178 - 178 (-2011)`

`= 178(-2021  + 2011)`

` = 178. (-10)`

`= -1780`

Answer 2

\(=2021\left(-125-53\right)-178\cdot\left(-2011\right)\)

\(=2021\cdot\left(-178\right)-178\cdot\left(-2011\right)\)

\(=-178\left(2021-2011\right)=-178\cdot10=-1780\)
