Question
**d. Show how to use a number line to calculate \(-1 - (-2)\).** To use a number line to solve \(-1 - (-2)\), follow these steps: 1. Locate \(-1\) on the number line. 2. Since subtracting a negative number is equivalent to adding a positive number, change \(- (-2)\) to \(+2\). 3. Move 2 units to the right from \(-1\). The final position is at \(1\). Thus, \(-1 - (-2) = 1\). **4. a. For each of these four expressions,** (Note: The task for this part involves multiple expressions not fully visible in the image. Further context or expressions are needed to complete this section.)
