You're working on
2-digit multiplication using the Box Method (also known as the Area Model or Grid Method). This method breaks down each number into tens and ones, multiplies the parts separately, then adds them up.
Let’s solve each problem step by step using the box method.

🔢 Problem 1: 35 × 8
Break 35 into
30 + 5
Draw a box with two columns: one for 30, one for 5. Multiply each by 8.
```
30 5
+-----------------
8 | 240 | 40
+-----------------
```
Add the products:
240 + 40 = 280
✔ Answer:
280

🔢 Problem 2: 47 × 9
Break 47 into
40 + 7
```
40 7
+-----------------
9 | 360 | 63
