Answer 1

Olá!!!

Resolução!!

a)
= ( + 7 ) - ( + 23 )
= 7 - 23
= - 16

b)
= ( - 65 ) + ( + 100 )
= ( - 65 ) + 100
= 35

c)
= ( + 111 ) + ( - 96 )
= 111 + ( - 96 )
= 15

d)
= ( - 72 ) + ( - 38 )
= - 72 - 38
= - 110

e)
= ( + 200 ) + ( - 251 )
= 200 + ( - 251 )
= 200 - 251
= - 51

f)
= ( + 72 ) + ( 330 )
= 72 + 330
= 402
