Determine the additive inverse of each

The rule of additive inverse is as follows;

Using the above, the solution is as follows:

Rule: 6 becomes -6 and - (-3) becomes +(-3)

So, the additive inverse is

Rule: -6 becomes 6 and -3 becomes 3

So, the additive inverse is

Rule: 6 becomes -6 and -3 becomes 3

So, the additive inverse is

Rule: -6 becomes 6 and -(-3) becomes +(-3)

So, the additive inverse is
