Subtracting Decimals from Whole Numbers

The video tutorial explains how to subtract decimal numbers using the column method. It begins by aligning the numbers correctly, ensuring the decimal points are in line. The process involves exchanging values to handle cases where a smaller number is subtracted from a larger one. The tutorial concludes with the final calculation, resulting in the answer 2.877.
