Question
Write the integer which is $4$ more than its additive inverse.
✓
Answer
Firstly, draw a number line. 
Let $+1$ be an integer and its additive inverse is $-1.$ From the number line, we see that $+1$ is $2$ more than its additive inverse. So, we reject this integer. Again, let $+ 2$ be an integer and its additive inverse is $-2.$ From the number line, we see that $+2$ is $4$ more than its additive inverse. Hence, the required integer is $2.$
