Use expanded form to add 28 and 41, showing 20 + 8 + 40 + 1 = 60 + 9 = 69.

The problem asks us to use expanded form to add the numbers 28 and 41, and find their sum. Let's go through the solution step by step, explaining each part clearly.

---

🔢 Step 1: Understand Expanded Form

Expanded form means breaking down a number into its place values — tens and ones.

- 28 = 20 (tens) + 8 (ones)
- 41 = 40 (tens) + 1 (one)

So we rewrite the addition like this:

```
28
+ 41
-----
```

becomes:

```
20 + 8
+ 40 + 1
--------
```

---

🔢 Step 2: Add the Tens and Ones Separately

Now, group and add the tens and ones separately:

- Tens: 20 + 40 = 60
- Ones: 8 + 1 = 9

Now combine them:

```
60 + 9 = 69
```

✔ Final Answer:

$$
\boxed{69}
$$

📌 Explanation Summary:

We used expanded form to break apart each number into tens and ones, added the tens together and the ones together, then combined the results. This method helps build number sense and understanding of place value.

✔ So, 28 + 41 = 69 using expanded form.
