( - 5 ) + ( - 10 ) + 16 + ( - 1 )= ( -15) + (15 ) =0
\(\left(-5\right)+\left(-10\right)+16+\left(-1\right)\)
\(=-\left(5+10\right)+\left(16-1\right)\)
\(=-15+15\)
\(=0\)
(-5) + (-10) + 16+ (-1)
= - ( 5+10) + ( 16-1)
= -15+15
= 0
Chúc bạn học tốt !
( - 5 ) + ( - 10 ) + 16 + ( - 1 )
= [( - 5) + ( - 1 )] + [ (-10 ) + 16]
= 6 + (- 26 )
= - 20
Sửa: ( - 5 ) + ( - 10 ) + 16 + ( - 1 )
= ( - 15 ) + 15
= 0
