Problem Description:
The task involves solving addition problems using a number line. Each problem requires adding two numbers and determining the result by visualizing the movement on the number line.
Solution:
####
Step 1: Understand the Number Line
A number line is a visual representation of numbers placed at equal intervals. To solve addition problems using a number line:
1. Start at the first number in the addition problem.
2. Move right by the number of steps equal to the second number.
3. The point where you land is the sum of the two numbers.
####
Step 2: Solve Each Problem
#####
Problem 1: \( 9 + 5 \)
- Start at 9 on the number line.
- Move 5 steps to the right.
- You will land on 14.
- Therefore, \( 9 + 5 = 14 \).
#####
Problem 2: \( 10 + 3 \)
- Start at 10 on the number line.
- Move 3 steps to the right.
- You will land on 13.
- Therefore, \( 10 + 3 = 13 \).
#####
Problem 3: \( 8 + 9 \)
- Start at 8 on the number line.
- Move 9 steps to the right.
- You will land on 17.
- Therefore, \( 8 + 9 = 17 \).
#####
Problem 4: \( 2 + 17 \)
- Start at 2 on the number line.
- Move 17 steps to the right.
- You will land on 19.
- Therefore, \( 2 + 17 = 19 \).
#####
Problem 5: \( 3 + 15 \)
- Start at 3 on the number line.
- Move 15 steps to the right.
- You will land on 18.
- Therefore, \( 3 + 15 = 18 \).
#####
Problem 6: \( 5 + 13 \)
- Start at 5 on the number line.
- Move 13 steps to the right.
- You will land on 18.
- Therefore, \( 5 + 13 = 18 \).
Final Answers:
\[
\boxed{14, 13, 17, 19, 18, 18}
\]
Explanation:
Each problem was solved by starting at the first number and moving right by the second number on the number line. This method helps visualize addition and ensures accuracy in finding the sum. The final answers are boxed for clarity.
