(2736 – 75 ) – 2736
= 2736 – 75 – 2736
= 2736 – 2736 – 75
= 0 – 75 = –75.

a) \(\left(2736-75\right)-2736.\)
\(=\left(2736-2736\right)-75.\)
\(=0-75=-75.\)
Vậy..........
b) \(-2002-\left(57-2002\right).\)
\(=-2002-57+2002.\)
\(=\left(-2002+2002\right)-57.\)
\(=0-57=-57.\)
Vậy..........
(2736-75)-2736= 2736-75-2736
= (2736-2736)-75
= 0-75
= -75
(-2002)-(57-2002)= -2002-57+2002
= (-2002+2002)-57
= 0-57
= -57

( 2736 - 75 ) - 2736
= 2736 - 75 - 2736
= 2736 - 2736 - 75
= 0 - 75
= - 75
(2736-75)-2736
=2736-2736-57
=0-57
