Question

-100-(-100)+95+(10-105)=?

Answer 1

`-100 - (-100) + 95 + (10 - 105)

= -100 + 100 + 95 + 10 - 105`

`= (-100 +100) + (95 + 10 - 105)`

`= 0 + 0`

`=0`

Answer 2

-100-(-100)+95+(10-105)

= -100+100+95+10-105

= 0

Answer 3

  - 100 - (-100)  + 95 + (10 - 105)

= - 100 + 100 + 95 + 10 - 105 

= - (100 + 100) - (105 - 95) + 10

= 0 - 10 + 10

=  - 10 + 10

= 0 

Answer 4

-100 - (- 100) + 95 + (10 - 105)

= - 100 + 100 + 95 + 10 - 105

= (- 100 + 100) + (95 + 10 - 105)

= 0 + (105 - 105)

= 0 + 0

= 0
