(-2002) -(57-2002)=
2002 - ( 57 - 62 + 2002 )
\(2002-\left(57-62+2002\right)\\ =2002-57+62-2002\\ =\left(2002-2002\right)-57+62\\ =62-57\\ =5\)
\(2002-\left(57-62+2002\right)\)
\(=2002-1997\)
\(=5\)
Tính nhanh tổng sau: (-2002) – (57 - 2002)
(–2002) – (57 – 2002)
= –2002 – 57 + 2002
= 2002 – 2002 – 57
= 0 – 57 = –57.

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

Vậy..........
(2736-75)-2736= 2736-75-2736
= (2736-2736)-75
= 0-75
= -75
(-2002)-(57-2002)= -2002-57+2002
