Question

Verify the following are equal or not:-
A. (-18) + 4 ] +6 = (-18) + (6 + 4)​

Answer 1

$\huge{\bf{\green{\mathfrak{Question:-}}}}$

• Verify the following are equal or not:-
• A. [(-18) + 4 ] + 6 = (-18) + [(6 + 4)]

$\huge {\bf{\orange{\mathfrak{Answer:-}}}}$

• $\sf{[(- \: 18) \: + \: 4] \: + \: 6 \: = \: (- \: 18) \: + \: [(6 \: + \: 4)]}$

• $\sf{[(- \: 14)] \: + \: 6 \: = (- \: 18) \: + \: [(10)]}$

• $\sf{- \: 14 \: + \: 6 \: = - \: 18 \: + \: 10}$

• $\sf{- \: 8 \: = \: - \: 8}$

• $\textsf{Hence, verified.}$

Answer 2

Question:

• Verify the following are equal or not:-
• A. (-18) + 4 ] +6 = (-18) + (6 + 4)

Solution:

L.H.S = [(-18) + 4] + 6

• = [ -18 + 4 ] + 6
• = [ -14 ] + 6
• = -14 + 6
• = -8

R.H.S = (-18) + (6+4)

• = -18 + (10)
• = - 18 + 10
• = -8

therefore,

L.H.S = R.H.S

Hence, Verified ✔️
