Answer 1

To multiply 45 by 81 by hand, you can use the standard multiplication method. Here's how it works step-by-step:

1. Write the numbers vertically, aligning them by the right:
```
45
× 81
____
```

2. Multiply the bottom number (1) by the top number (45):
```
45
× 81
____
45 (1 * 45)
```

3. Now, multiply the bottom number (8) by the top number (45). Since the 8 is in the tens place, we add a zero to the right:
```
45
× 81
____
45 (1 * 45)
+360 (8 * 45, shifted one position to the left)
____
```

4. Now, add the two results together:
```
45
+360
____
3645
```

So, \( 45 \times 81 = 3645 \).

Therefore, the answer is **3,645**.
