A = [ - 506 + 732 - ( - 2000 )]-( 506 1732)

A = [ 226 + 2000 ]-506 + 1732

A = 174 - 506 + 1732

A = 1268 + 1732

A =       3000

  -[-506+732-(-2000)]-(506-1732)

=506-732-2000-506+1732

=-1000

Xong rồi đó, nhớ k cho mik nha

-[-506 + 732 - (-2000)]-(506-1732)

= 506-732+(-2000)-506+1732

=(506-506)+(-732+1732)-2000

=0+1000-2000

=1000-2000

= -1000

A=[-506+732+2000]-(-1226)

A=2226+1226

A=3452

\(A=-\left[-506+732-\left(-2000\right)\right]-\left(506-1732\right)\)

\(\Rightarrow A=-\left(-506+732+2000\right)-\left(506-1732\right)\)

\(\Rightarrow A=506-732-2000-506+1732\)

\(\Rightarrow A=\left(506-506\right)+\left(1732-732\right)-2000\)

\(\Rightarrow A=0+1000-2000\)

\(\Rightarrow A=-2000+1000\)

\(\Rightarrow A=-\left(2000-1000\right)\)

\(\Rightarrow A=-1000\)

\(A=-\left[-506+732-\left(-2000\right)\right]-\left(506-1732\right)\)

\(\Leftrightarrow A=-\left(-506+732+2000\right)-\left(506-1732\right)\)

\(\Leftrightarrow A=506-732-2000-506+1732\)

\(\Leftrightarrow A=\left(506-506\right)+\left(1732-732\right)-2000\)

\(\Leftrightarrow A=0+1000-2000\)

\(\Leftrightarrow A=1000-2000=-1000\)

Vậy ....................

mình viết thiếu để mình viết lại

A = - [ - 506 + 732 - ( - 2000 ) ] - ( 506 - 1732 )

A = 506 - 732 + (- 2000) - 506 + 1732

A = (506 - 506) - (732 - 1732) - 2000

A = 0 - (-1000) - 2000

A = 1000 - 2000 = -1000

máy tính tính ra = -1000

 -[-506+732-(-2000)(]-(506-1738)
=-506-732+200-506+1738
=(-506+506)+(1732-732)-2000
=0+1000-2000=-1000

-1000 ai ko tick tớ sau này sinh con đều có mặt chó

-{-506+732-(-2000)-(506-1732)

=-{-506+732-2000-(506+1732)

=-{-506+506)-2000-1732

=-{0-2000-1732}

=-{-2000+1732}

=(-3452)

A= [ -506 + 732 - ( -2000 ) ] - (- 1226)

A= (- 426 ) + (- 1226 )

A= - 1625
