bỏ dấu ngoặc rồi tính

Answer 1

(-127)-(2017+627)+(2017)

=-127-2017-627+2017

=-127+(-2017)+(-627)+2017

=[-127+(-627)]+(-2017+2017)

=-754+0

=-754.

Answer 2

(-127)-(2017+627)+(2017)

= -127 - 2017 + 627 + 2017

= (-2017 + 2017) + (-127+627)

= 0 + 500

=500

Answer 3

(-127) - (2017 + 627) + (2017)

= -127 - 2017 - 627 + 2017

= -127 - 2017 + 2017 - 627

= -127 - 627

= -754

Answer 4

=-127-2017-627+2017

=[(-127)+(-627)]-[(-2017)+2017}

=-754-0

=754
