The image shows a multiplication problem solved using the
partial products method, which breaks down numbers into their place values (tens and ones) to simplify multiplication. Let's go through the solution step by step.

🔢 Problem:
Multiply:
34 × 46
---
🧩 Step 1: Break Down the Numbers
We break both numbers into tens and ones:
-
34 = 30 + 4
-
46 = 40 + 6
Now, we multiply each part of 34 by each part of 46 using a grid (also called the area model).

📊 Partial Products Grid
| |
30 |
4 |
|-------|--------|-------|
|
40 | 1200 | 160 |
|
6 | 180 | 24 |
Let’s compute each partial product:
1.
40 × 30 = 1200
2.
40 × 4 = 160
3.
6 × 30 = 180
4.
6 × 4 = 24

➕ Step 2: Add All Partial Products
Now, add all the partial products:
```
1200
+ 160
+ 180
+ 24
------
1564
```
✔ Final Answer:
1564
---
✔ Verification (Optional)
Check with standard multiplication:
```
34
× 46
----
204 ← 34 × 6
1360 ← 34 × 40
-----
1564
```
Same result! ✔️

✔ Conclusion:
Using the
partial products method, we broke down the multiplication into smaller, easier steps and added them up:
>
34 × 46 = 1564
This method helps understand how multiplication works based on place value.
