Answer 1

To solve the multiplication of 13 and 17 using the standard method, we can follow these steps:

1. **Multiply 13 by 7 (the units digit of 17)**:
\[
13 \times 7 = 91
\]
We write 91 below the line.

2. **Multiply 13 by 1 (the tens digit of 17)** and shift it one place to the left (which is the same as multiplying by 10):
\[
13 \times 1 = 13 \quad \text{(this represents 130)}
\]
We write this below the 91, shifted one position to the left.

Now we have:

```
13
x 17
------
91 (13 x 7)
+130 (13 x 1, shifted one position)
------
```

3. **Add the two results together**:
\[
91 + 130 = 221
\]

So the multiplication looks like this:

```
13
x 17
------
91
+130
------
221
```

The final answer is:
```
221
