We will solve the multiplication of decimal numbers using the vertical multiplication method.**We will proceed in the following order:**

- We will neatly write the multiplication exercise in vertical form β one decimal point under the other decimal point, tenths under tenths, hundredths under hundredths, etc.
- We will solve the exercise and, for now, will not pay attention to the decimal point.
- We will strictly adhere to the rules of vertical multiplication.
- We will review each number in the exercise and find out how many digits there are after the decimal point.
- We will count the total number of digits after the decimal point (taking into account both numbers) and that will be the number of digits after the decimal point in the final answer.
