Let's solve each addition problem
step by step using the
number line method. The idea is to:
1. Start at the first number.
2. Move forward (to the right) by the number of steps equal to the second number.
3. The number you land on is the answer.
We'll go through each question and show how to do it on the number line, then give the final answer.

🔍 How to Show It on the Number Line:
For each problem, draw a
jump from the starting number to the end number.
Example for
9 + 4:
```
<---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|--->
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15
↑ ↗↗↗↗
9 +4 → 13
```
You can draw arrows from 9 to 10, 10 to 11, 11 to 12, 12 to 13 — or one long arrow from 9 to 13.
