Step-by-step explanation:

Given

Required

Determine the additive inverse of each

The rule of additive inverse is as follows;

  • For any positive number (n), the additive inverse is (-n)
  • And for any negative number (-n), the additive inverse is (n)

Using the above, the solution is as follows:

1.\ 6 - (-3)

Rule: <em>6 becomes -6 and - (-3) becomes +(-3)</em>

So, the additive inverse is -6 + (-3)

2.\ -6 -3

<em />

Rule: <em>-6 becomes 6 and -3 becomes 3</em>

So, the additive inverse is 6 + 3

3.\ 6 - 3

Rule: <em>6 becomes -6 and -3 becomes 3</em>

So, the additive inverse is -6 + 3

4.\ -6 - (-3)

Rule: -<em>6 becomes 6 and -(-3) becomes +(-3)</em>

So, the additive inverse is 6 + (-3)
