Podiam me ajudar pfv?

Answer 1

a)
 = - 6 : 6 - 10
= - 1 - 10
= - 11

**********************
b)
 = - 100 + 20 : 2
= - 100 + 10
= - 90

***************************
c)
= - 15 + 10 : ( 2 - 7)
= - 15 + 10 : (-5)
= - 15 - 2
= - 17

***************************
d)
= + 1 - 24 : ( 3  + 5)
= 1 - 24 : 8
= 1 - 3
= - 2

************************
e)
 = - 2 + 4 : ( 2 - 6)
= - 2 + 4 : ( - 4)
= - 2 - 1
= - 3

******************************
f)
= + 15 : ( -15 ) +1
= - 1 + 1
= 0

*****************************
g)
= + 28  : ( +9  - 3 +1 )
= 28 : ( 6 + 1)
= 28 : 7
= 4

******************************
h)
 = ( - 5 - 7 ) : ( +1 - 3) 
= (- 12) : (- 2)
= + 6
