Multiplying Decimals and Visual Models

The video tutorial explains two methods for multiplying decimals: a visual model using a 10x10 grid and the standard algorithm. The visual model involves shading rows and columns to find the overlapping area, representing the product. The standard algorithm involves multiplying as with whole numbers and adjusting for decimal places. Both methods demonstrate how to find the product of four tenths and six tenths, resulting in twenty-four hundredths.
