b) -3 +9 - 10 - 8 + 16 - 2 + 24
c) +13 - 7 - 6 - 9 + 14
d) -25 + 3 - 18 + 21 - 30 - 16
e) -30 - 4 + 9 + 15 - 20 + 14
f) -22 + 18 + 16 -3 + 21 - 10 + 17
g) -10 + 10 + 7 - 3 - 7 + 3 - 1​

Answer 1

Resposta:

a)5-2 =3 +7=10-3=7+1=8 ( R:8 )

b)-3+9=6-10= -4 -8= -12+16=4 -2=2+ 24=26 ( R:26 )

c)+13-7=6-6=0-9= -9+14 = 5 ( R:5)

d)-25+3= -22-18= -44+21= -23-30=53-16= -69 ( R:69 )

e)-30-4= -34 +9= -25 +15= -10-20= -30+14 = -16 ( R:-16 )

f) -22+18= -4+18=14+16=30 -3=27+21=48-10=38+17=55( R:55 )

g)-10 +10=0+7=7-3=4 -7=3+3=6-1= 5 ( R:5 )
