Question

Write the integer which is 4 more than its additive inverse.

Answer 1

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.
