Question

Answer 1

`a) (2736 - 2019) - 2736`

`=2736 - 2019 - 2736`

`=(2736  - 2736 ) -2019`

`=0-2019 = -2019`

`b) - 8715 + (1345 + 8715)`

`=- 8715 + 1345 + 8715`

`=(- 8715 + 8715) +  1345`

`=0 + 1345 = 1345`

Answer 2

`(2736 - 2019) - 2736`

`=2736 - 2019 - 2736`

`=(2736 - 2736) - 2019`

`=0-2019`

`=-2019`

_______________________________

`-8715 + (1345 + 8715)`

Answer 3

a, (2736 - 2019) - 2736

= 717 - 2736

a, -8715 + (1345 + 8715)

= -8715 + 10060

= 1345.
