b) (-8)-(+2)-(-1)×(-6)
c)20-(-5)-12-1-(-3)
d)18-(-18)+7(-7)-4
e)10-(-12)-(-8)+(-9)-6+1+5
f)-32-1-(-12+14)​

Answer 1

Resposta:

a) -5 b) -16 c) 15 d) 32 e) 21 f) -7

Explicação passo a passo:

a)(-5)-(-2)-(+3)-(-1) = -5+2-3+1 = -3-2 = -5

b) (-8)-(+2)-(-1)×(-6) = -8-2+1×(-6) = -10-6 = -16

c)20-(-5)-12-1-(-3) =20+5-12-1+3= 25-12+2=15

d)18-(-18)+7(-7)-4 =18+18+7-7-4 =36-4= 32

e)10-(-12)-(-8)+(-9)-6+1+5= 10+12+8-9-6+1+5 =30-9 = 21

f)-32-1-(-12+14)​ = -32-1+12+14 = -33+26 = -7
