Question

if a=(-8) and b=(-6) and c=(-8) verify that (a+b) +c=a+(b+c)​

Answer 1

Answer:

given

a=(-8)

b=(-6)

c=(-8)

L.h.s

(a+b)+c = [(-8)+(-6)]+(-8)

= (-8-6)-8

= -14-8

= -22

now, R.h.s

a+(b+c)

= (-8)+[(-6)+(-8)]

= -8+(-6-8)

= -8-14

=-22

l.h.s = r.h.s

hence, proved

Answer 2

Answer:

(-8-6)-8= -8+(-6-8)

-14-8= -8-14

-22= -22
