Find the following using the number line:
`15-5`

Answer

To solve the problem \(15 - 5\) using a number line, follow these steps:

### Step-by-Step Solution:

1. **Draw a Number Line**: Start by drawing a horizontal line. Mark equal intervals on this line to represent whole numbers. You can label the numbers from 0 to 15.

**Hint**: Make sure the intervals are evenly spaced so that the numbers are easy to read.

2. **Identify the Starting Point**: Since we are subtracting from 15, locate the number 15 on the number line. This will be your starting point.

**Hint**: Remember, 15 is the largest number in this operation, so it will be on the right side of the number line.

3. **Move Backward**: Since we are subtracting 5, you need to move 5 steps to the left from 15. Each step to the left represents subtracting 1.

**Hint**: Count each step carefully. Moving left decreases the value of the number.

4. **Count the Steps**:
- From 15, move to 14 (1 step)
- Then to 13 (2 steps)
- Then to 12 (3 steps)
- Then to 11 (4 steps)
- Finally, to 10 (5 steps)

**Hint**: Keep track of how many steps you have taken to ensure you move exactly 5 steps.

5. **Identify the Result**: After moving 5 steps to the left from 15, you land on 10. Therefore, \(15 - 5 = 10\).

**Hint**: The final position on the number line gives you the answer to the subtraction problem.

### Final Answer:
Thus, \(15 - 5 = 10\).
