\(2002-\left(57-62+2002\right)\\ =2002-57+62-2002\\ =\left(2002-2002\right)-57+62\\ =62-57\\ =5\)

\(2002-\left(57-62+2002\right)\)

\(=2002-1997\)

\(=5\)

-2002-(57-2002) = -2002-57+2002=-57

(–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) \(-2002-\left(57-2002\right).\)

\(=-2002-57+2002.\)

\(=\left(-2002+2002\right)-57.\)

\(=0-57=-57.\)

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

a)(2736-75)-2736=(2736-3736) - 75

=0-75

=-75                        

b)(-2002)-(57-2002)=(-2002-2002)-57

=-4004-57

=-3947

20020 : 10 = 2002

\(20020:10=200200:100=2002000:1000=20020000:10000\)

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

(2002)-(57-2002)

=2002-2002-57

=0-57

=-57

Ai k mình mình lại

(2002)-(57-2002)

=2002-57+2002

=(2002-2002) + 57

=0 + 57

= 57
