Question

If a=-7 ,b=-8and c=5,verify that (a+b)+c=a+(b+c)

Answer 1

Answer:

Step-by-step explanation:

[a+b]+c=a+[b+c]

putting a = -7,b = -8 ,c =5

-7+[-8]+5= -7+[-8+5]

-7 -8 +5 = -7-8+5

-15+5=-15+5

-10=-10

lhs =rhs

hence ,verified

Answer 2

Answer:

Addition satisfies Associativity

Step-by-step explanation:

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

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

Hope it helps :)
