## 📝 Explanation Summary:

To multiply a 3-digit number by a 2-digit number:

1. Multiply the 3-digit number by the ones digit of the 2-digit number.
2. Multiply the 3-digit number by the tens digit of the 2-digit number — and remember to shift this result one place to the left (i.e., add a zero at the end or think of it as multiplying by 10, 20, 30, etc.).
3. Add the two partial products together to get the final answer.

This method is called the “standard algorithm” or “long multiplication.”
