Question

8. if a = -7 ,b = -8 and c = 5 , verify that (a+b) +c = a + ( b+ c) .​

Answer 1

LHS: (a+b)+c= ((-7) + (-8)) + 5 = -15 + 5 = -10

RHS: a+(b+c)= (-7) + ((-8) + 5) = -7 - 3 = -10

LHS = RHS........ Hence, Verified.

Answer 2

Answer:

they are equal

(-7-8)+5= -7+(-8+5)

-15+5= -7-3

-10= -10
