Question

if a=-2,b=-5,c=6,verify that [a+b]+c=a+[b+c]

Answer 1

Step-by-step explanation:

Substituting the values ,

LHS = [-2+(-5)] + 6

= (-2-5) + 6

= -7+6

= -1

RHS = -2 + [-5 + 6 ]

= -2 + (1)

= -2+1

= -1

Therefore , from the values obtained from LHS & RHS , i.e, -1 , the given equation is true and verified.
