Answer:

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

Explanation:

a= (-12), b = 4, c = (-25)


(12) + (4 + ( - 25)) = ( - 12 + 4) + ( - 25) \\ - 33 = - 33

Answer:

GIVEN :-

  • a = -12
  • b = 4
  • c = -25

TO VERIFY :-

  • a + (b + c) = (a + b) + c

SOLUTION :-

Find the values of L.H.S. & R.H.S.

L.H.S. :-

Put all values in →
\boxed{a+(b+c)}

⇒ -12 + [4 + (-25)]

⇒ -12 + (4 - 25)

⇒ -12 + (-21)

⇒ -12 - 21

-33

R.H.S. :-

Put all values in →
\boxed{(a+b)+c}

⇒ (-12 + 4) + (-25)

⇒ -8 - 25

-33

CONCLUSION :-

L.H.S. = R.H.S.

⇒ a + (b + c) = (a + b) + c
