Trl:
-24 - (-64) - 75 + 36
= -24 + 64 - 75 + 36
= 40 - 75 + 36
= -35 + 36
= 1
Hc tốt
- 24 - ( - 64 ) - 75 + 36
= - 24 + 64 - 75 + 36
= (- 24 - 75 ) + ( 64 + 36 )
= - 99 + 100
= 1
\(-24-\left(-64\right)-75+36\)
\(=-24+64-75+36\)
\(=\left(-24-75\right)+\left(64+36\right)\)
\(=-99+100\)
= \(1\)
Trả lời :
-24 - ( - 64 ) - 75 + 36
= -24 + 64 - 75 + 36
= ( -24 - 75 ) + ( 64 + 36 )
= -99 + 100
= 1
