Question

5
Use a number line to add
+(-1).

Answer 1

To visualize the addition of \( +(-1) \) using a number line, you can follow these steps:

1. **Start at Zero:** Locate the point at zero on the number line.

2. **Move Left:** Since you are adding a negative number (-1), you will move to the left on the number line. Moving left represents subtracting.

3. **Count the Steps:** Move one unit to the left from zero.

This brings you to the point \(-1\) on the number line.

Therefore, \(0 + (-1) = -1\).
