a/ (2736 - 75 ) - 2736 = 2736 - 75 - 2736 = -75
b/ (-2002) - (57 - 2002) = (-2002) - 57 + 2002 = -57

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

a) (2736 – 75) – 2736
= 2736 – 75 – 2736
= (2736 – 2736) – 75
= 0 – 75
= – 75
b) (- 2002) – (57 – 2002)
= (– 2002) – 57 + 2002
= (– 2002 + 2002) – 57
= 0 – 57
= – 57
a) (2736 – 75) - 2736
= 2736 - 75 – 2736 (bỏ dấu ngoặc có dấu "+" đằng trước)
= 2736 – 2736 - 75
= 0 - 75
= -75
2) – (57 - 2002)
= -2002 - 57 + 2002 (bỏ dấu ngoặc có dấu "-" đằng trước)
= -2002 + 2002 - 57
= 0 - 57
= -57
