Multiplication and Estimation Techniques

The video tutorial guides viewers through a multiplication problem involving money. It begins with estimating the result by rounding numbers, then proceeds to the multiplication process, ignoring the decimal point initially. Finally, the decimal point is placed in the correct position to get the final answer.

What is the main task introduced at the beginning of the video?
