🔍 How to Solve Column Multiplication (Step-by-step):

For any problem like `ABC × DE`:

1. Multiply the top number by the ones digit of the bottom number.
2. Multiply the top number by the tens digit of the bottom number (shift one place to the left).
3. Add the two results.

Example:
```
458
× 79
-----
4122 ← 458 × 9
32060 ← 458 × 70 (shifted)
-------
36182
```

This method ensures accuracy and helps avoid errors in large multiplications.
