Question

A=-7-3-2
A=-10-2
A= -12

B = (-(-4) +(-3)-21-5))
B=4-3-(2) (-5)
B=1-(-10)
B=11

C=-7-4-2(-3) -(-4)}
C= 11-(-2)-(-3) -(-4)
C = 11-(-6) -(-4)
C=5-(-4)
C=-1

D=(1-3-(-4)-(-7)}
D=-2-(-4)-(-7)
D=2-(-7)
D= 9

resolver : a+b , a+ c , c+b , a+d
​

Answer 1

Respuesta:

a + b = -12 + 11 = -1

a + c = -12 - 1 = -13

c + b = -1 + 11 = 10

a + d = -12 + 9 = -3

Answer 2

A + b = -12 + 11 = -1

A + b = -12 - 1 = -13

C + b = -1 + 11 = 10
