Question

if a = -8 , b = -7 and c = 6 then verify that (a+b)+c = a+(b+c)​

Answer 1

Answer:

Communicative Property of addition

(-8+-7)+6=. -8+(-7+6)

-15+6=-8+-1

-9=-9

Since,L.H.S=R.H.S

Hence,proved

Answer 2

Step-by-step explanation:

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

(-8-7)+6 = -8+(-7+6)

-15+6 = -8-1

-9 = -9

9 = 9
