Question

( -2) + (-2) + (-2) + (-2) + (-2) =_____ . (-2) =______

Answer 1

⇒ ( - 2 ) + ( - 2 ) + ( - 2 ) + ( - 2 ) + ( - 2 )

⇒ - 2 - 2 - 2 - 2 - 2

⇒ -( 2 + 2 + 2 + 2 + 2 )

⇒ - ( 10 )

⇒ - 10

According to the question, first blank = ___.( - 2 )

∴ - 10 = ___.( - 2 )

Let the black will be filled with x.

∴ - 10 = x( - 2 )

⇒ - 10 / - 2 = x

⇒ 5 = x

Therefore, ( - 2 ) + ( - 2 ) + ( - 2 ) + ( - 2 ) + ( - 2 ) = 5.( - 2 ) = - 10.
