Question

2016-(2026+2017)+(-2015+2017)

Answer 1

2016-(2026+2017)+(-2015+2017)

= 2016-2026-2017-2015+2017

= 2016-2015-2026

=1-2026

=-2025

Answer 2

2016 - ( 2026 + 2017 ) + ( -2015 + 2017 )

= 2016 - 2026 - 2017 - 2015 + 2017

= ( 2016 - 2026 ) - ( 2017 - 2017 ) - 2015

= -10 - 2015

= -2025

Answer 3

2016 - (2026 + 2017) + (-2015 + 2017)

= 2016 - 2026 - 2017 - 2015 + 2017

= (2016 - 2026) + (-2017 + 2017) - 2015

= -10 + 0 - 2015

= -10 - 2015

= -2025

Answer 4

2016 - (2026 + 2017) + (- 2015+2017)

= 2016 - 2016 - 2017 + (-2015) + 2017

= - 2015
