Answer 1

Respuesta:

Mira los procedimientos

Explicación paso a paso:

esta muy sencillo, solo usa ley de signos

(-)(-) = +

(+)(-) = -

(-)(+) = -

(+)(+) = +

ahora sí vamos a resolver

2(-3+1) = -6 + 1 = -7

-(-8)+12+(-5)-3= 8+12+(-5)-3= 20-8= -12

-1(-2)×3×(-5)= 2×3×(-5)= 2×-15= -30

-(-6)-(6+3)= 6-6-3 = -3

-3×(-5+2)= -3(-3)= 9

1-(-7+4)+(-2)= 1-(-3)+(-2)= 4-2= 2

-4×(-3)×(-5)= 12(-5)= -60

-12-(8+4-5)+(-1)= -12-(7)+(-1)= -12-7-1= -20

-2×3(-5)= -2 (-15) = 30
