Answer 1

(-1975)-(-128-1975)-(128+570)

=-1975-128+1975-(-128)-570

=(1975-1975)+[128+(-128)-570

=      0            +       0          -570

=                     -570

Answer 2

Answer 3

Bỏ ngoặc ta có : -1975-(-128)-1975-128+570

= -1847-1975-689

=-3822-689

=-4511

Answer 4

\(\left(-1975\right)-\left(-128-1975\right)-\left(128+570\right)\)

\(=-1975+128+1975-128-570\)

\(=\left(-1975+1975\right)+\left(128-128\right)-570\)

\(=-570\)

Answer 5

(-1975) - (-128 - 1975) - (128 + 570).

= -1975 + 128 + 1975 - 128 - 570

= [(-1975) + 1975] + (128 - 128) - 570

= 0 + 0 - 570

= -570.
