Answer 1

Answer:

The opposite (also known as the additive inverse) is the number we have to add to get an answer equal to the additive identity,

0

. Since

=

(

)

+

1

=

0

, the opposite of

1

is

−

1

.

The reciprocal (also known as the multiplicative inverse) is the number we have to multiply to get an answer equal to the multiplicative identity,

1

. Since

1

, the reciprocal of

1

is
