Question

completar la tabla teniendo en cuenta la informacion inicial

Answer 1

A) a+b= -2-3= -5
b+a= -3-2= -5
b+0= -3+0= -3
a+(-a)= -2+2= 0
a+(b+c)= -2+(-3+5)= -2+2= 0
(a+b)+c= (-2-3)+5= -5+5= 0
B) a+b= -6-2= -8
b+a= -2-6= -8
b+0= -2+0= -2
a+(-a)= -6+6= 0
a+(b+c)= -6+(-2+3)= -6+1= -5
(a+b)+c= (-6-2)+3= -8+3= -5
C) a+b= -7-8= -15
b+a= -8-7= -15
b+0= -8+0= -8
a+(-a)= -7+7= 0
a+(b+c)= -7+(-8-1)= -7-9= -16
(a+b)+c= (-7-8)+-1= -15-1= -16
