Question

Find the sum -8+(4) using a number line model

Answer 1

The first step to solve this question is drawing the number line:

Now, we have to place the first integer on the line. In this exercise, it is -8. So

Now, we look at the second integer. It is positive, plus 4. This means that we move 4 units to the right on the line. Four units to the right from -8 is -8 + 4 = -4. So.

The final answer is -4.
