(-7+|13|)-(13-|-7|-25)-(25+|-10|-9)=(-7+13)-(13-7-25)-(25+10-9)
= 6-(-19)-26
=6+19-26
= -1
cho 1 đúng nhé!
\(\left(-7+|13|\right)-\left(13-|-7|-25\right)-\left(25+|-10|-9\right)\)
\(=\left(-7+13\right)-\left(13-7-25\right)-\left(25+10-9\right)\)
\(=6-\left(-19\right)-26\)
\(=6+19-26\)
\(=-1\)
Chúc bn hk tốt ^_^
(-7 + l13l) - (13-l-7l - 25 ) - (25 + l-10l-9)
= -7 -13 - 13 + 7 + 25-25 - 10 + 9
=(-7 + 7) + ( -13 +13) + (25 - 25) +9
=0 + 0 +0 +9
=9
