b, theo đề ra ta có:
= 85.8 - 35.58
= 680 - 2030
= - 1350
![](https://rs.olm.vn/images/avt/0.png?1311)
34 + 27 - (85 + 27) + 85
=34 + 27 -112 + 85
=61 - 112 + 85
= - 51 + 85
= 34

85.(35-27)-35.(85-27)
=85.35-85.27-35.85-35.27
=85.35(1-1)-27(85-35)=
=0-27.50
=-1350
b)
16.(38-12)-38(16-12)
=16.38-16.12-38.16-38.12
=16.38(1-1)-12(16-38)
=16.38.0-12.-22
=0+264
=264

\(77-11\left(30+7\right)=77-11.30+11.7\)
\(=77-77-330=0-330\)
\(=-330\)
trả lời:
\(77-11.\left(30+7\right)\)
\(=77-11.30+11.7\)
\(=77-77-330\)
\(=0-330\)
\(=-330\)

85.(35-27)-35(85-27)=85.35-85.27-35.85+35.27
=(85.35-35.85)+(85.27-35.27)=0+27.(85-35)=27.40=1080
85.(35-27)-35(85-27)
=85.35-85.27-35.85+35.27
=(85.35-35.85)+(85.27-35.27)
=0+27.(85-35)=27.40=1080
tick nhé
27 + [ 85 + ( - 27 ) + 115 ] : 100
= 27 + 173 : 100
= ( 27 + 173 ) : 100
= 200 : 100
= 2
27+(-27)+(85+115)÷100
=0+200÷100
=200÷100
=2
