b1 : tinhs 

a 7 - ( - 8 ) . 3 + 16

b - 8 : ( -4 ) + 12 - ( - 3 ) 

c 7 . ( - 2 ) - 8 . 3 + 1 

d. 98 . ( - 6 : 2 ) + 32 

e 56 : 7 + 8 - 16

Answer 1

\(\text{a},=7-\left(-24\right)+16=31+16=47\\ b,=2+12-\left(-3\right)=14-\left(-3\right)=17\\ c,=-14-24+1=-38+1=-37\\ d,=98.\left(-3\right)+32=-294+32=-262\\ e,=8+8-16=0\)

Answer 2

` 7 - ( - 8 ) . 3 + 16`

`=7 + 8 . 3 + 16`

`=7 + 24 +16`

`=31 + 16`

`=47`

___________________

`- 8 : ( -4 ) + 12 - ( - 3 ) `

`= (-8) : (-4) + 12 + 3`

`=2 + 12 + 3`

`=14 + 3`

`=17`

_________________________

`7 . ( - 2 ) - 8 . 3 + 1 `

`= -14 - 24 + 1`

`=-38 + 1`

`=-37`

__________________________

`98 . ( - 6 : 2 ) + 32 `

`=98 . (-3) + 32`

`=-294+ 32`

`=-262`

______________________________

` 56 : 7 + 8 - 16`

`=8 + 8 - 16`

`=16-16`

`=0`

Answer 3

a,=7−(−24)+16=31+16=47b,=2+12−(−3)=14−(−3)=17c,=−14−24+1=−38+1=−37d,=98.(−3)+32=−294+32=−262e,=8+8−16=0
