Question

If a is = 8, b = to -7 ,C = 6 then verify that (a+b)+c=a+(b+c)

Answer 1

Answer:

a=8

b= -7

c=6

then,

(a+b)+c

=(8-7)+6

=1+6

=7

a+(b+c)

=8+( -7+6)

=8+( -1)

=8-1

=7

so verified that (a+b)+c=a+(b+c)

Answer 2

Step-by-step explanation:

(a+b)+c

(8+-7)+6

(8-7)+6

1+6

7

a+(b+c)

8+(-7+6)

8+(-1)

8-1

7

(a+b)+c=a+(b+c)

hence proved.
