A = -[-506+732-(-2000)]-(506-1732)
A = -[ 226 -(-2000)]-( -1226)
A = -2226 -( -1226)
A = -1000
= - 3000 ban nha nho tk mk nha
A = -( 506+732+2000)-506-1732
A = 506+(-506)-732+1732-2000
A=-1000
Trả lời:
\(A=-\left[-506+732-\left(-2000\right)\right]-\left(506-1732\right)\)
\(A=-\left(-506+732+2000\right)-506+1732\)
\(A=506-732-2000-506+1732\)
\(A=\left(506-506\right)+\left(-732-2000+1732\right)\)
\(A=0-1000\)
\(A=-1000\)
