Question

Is (–15) × [(–7) + (–1)] = (–15) × (–7) + (–15) × (–1)?

Answer 1

-90=90+15
-90 is not equal to 105

Answer 2

(–15) × [(–7) + (–1)] = (–15) × (–7) + (–15) × (–1)

LHS :

(–15) × [(–7) + (–1)]

= -15 x (-8)

= 120

RHS:

(–15) × (–7) + (–15) × (–1)

= -15 ( - 7 - 1)

= -15 (-8)

= 120

LHS = RHS

⇒ There are equal
