-Chúc bạn học tốt-
a) (-124) + 24 = -100
b) 37. 78 + 37. 22
= 37 . ( 78 + 22 )
= 37 . 100
= 3700
a,- 129 - 72 -( - 29 ) + ( - 28 ) + 2017
= - 200 +2017
= 1817
b, ( - 35 ) . 37 - 37 . 5 + ( - 37 ) . 60
= - 1295 - 185 + ( - 2220 )
= - 3700
a ) = 37.[ ( - 75 ) - 25 ] = 37 .( - 100 ) = - 3700
b ) = 36 + ( - 90 ) + ( - 8 ) = - 62
a)=37.(-75)+37.(-25)
=37.[(-75)+(-25)]
=37.(-100)
=-3700
mình nha
\(=\left[37.\left(23-11\right)\right]\div37\)
\(=\left[37.12\right]\div37\)
\(=444\div37=12\)
\(=-37\cdot1+37\cdot382-382\cdot37=-37\)
