Question

uu UV - Tuis uld -04) - 36. Are they equal?
10. If a = -8, b = -7, C = 6, verify that (a + b) + c = a +(b + c)..​

Answer 1

$( - 8 - 7) + 6 = - 8 + ( - 7 + 6) \\ - 15 + 6 = - 8 + ( - 1) \\ - 9= - 9 \\ hence \\ l.hs = r.hs$

Answer 2

Answer:

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

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

-8+-1=-15+6

-9=-9

hence,

l.h.s=r.h.s

So,it is verified that (a + b)+c = a + (b + c)
