Question

Find the additive identity of -3+(-2)÷2

Answer 1

Answer:

keep smiling.....

Step-by-step explanation:

For a number

a

, it's multiplicative inverse

b

is such that

a

⋅

b

=

1

which is the multiplicative identity.

For a number

a

, it's additive inverse

c

would be such that

a

+

c

=

0

where

0

is additive identity.

Thus, for

a

=

−

8

It's additive inverse be

c

.

Then

−

8

+

c

=

0

Now, adding

8

to both sides,

c

=

8

.

Let the multiplicative inverse be

b

.

Then

a

⋅

b

=

1

⇒

−

8

⋅

b

=

1

Multiplying both sides with

−

1

8

b

=

−

1

8
