Question

Tính hợp lý : (589-732)-(589+2011-732)

Answer 1

(589-732)-(589+2011-732)

= 589-732-589-2011+732

= (589-589)+(732-732)-2011

= 0+0-2011

=-2011

Answer 2

\(\left(589-732\right)-\left(589+2011-732\right)\)

\(=589-732-589-2011+732\)

\(=\left(589-589\right)+\left(-732+732\right)-2011\)

\(=-2011\)
