╭(╯^╰)╮，快点来，初中数学题，！~初一的

原式=-40-27+9-24+32=-(40+27+24)+9+32=-91+41=50
原式=5*1/5-[13/6+(-4.8)-(-29/6)]=5*1/5-(13/6+29/6-4.8)=5.2-(7-4.8)=3

1 解:原式=-40-27+19-24+32
=-(40+27+24)+(19+32)
=-91+51
=-40

2 解:原式=5又5分之1-(2又6分之1-4.8+4又6分之5)
=5又5分之1-(2又6分之1+4又6分之5-4.8)
=5.2-(7-4.8)
=5.2-2.2
=3

1. -40-27+19-24+32
=-67+19-24+32
=-[67+24]+19+32
=-91+19+32
=-40
2. 26/5-[13/6-4.8+29/6]
=26/5-42/6+4.8
=3

1. {-40}-{+27}+19-24-{-32}
={-40}+{-27}+19-24+32
={-40}-27+19-24+32
=-77+19-24+32
=-58-24+32
=-82+32
=-50

1. =(-40)+(-27)+19+(-24)+(32)
=(-67)+(-8)+8
=(-75)+8
=-67
好了,那个我没学,我也初一.
