Describe how to find the sums -4 + 2 and -4 + (-2) on a number line

To find the sums \(-4 + 2\) and \(-4 + (-2)\) on a number line, follow these steps:

### 1. **Finding the sum of \(-4 + 2\):**
   - **Step 1:** Start at \(-4\) on the number line.
   - **Step 2:** Since you're adding a positive number (\(+2\)), move 2 units to the right.
   - **Step 3:** After moving 2 units to the right, you land on \(-2\).
   - **Result:** \(-4 + 2 = -2\).

### 2. **Finding the sum of \(-4 + (-2)\):**
   - **Step 1:** Start at \(-4\) on the number line.
   - **Step 2:** Since you're adding a negative number (\(-2\)), move 2 units to the left.
   - **Step 3:** After moving 2 units to the left, you land on \(-6\).
   - **Result:** \(-4 + (-2) = -6\).

### Summary:
- \(-4 + 2\) is found by moving right and equals \(-2\).
- \(-4 + (-2)\) is found by moving left and equals \(-6\).
