Decimal Multiplication with Hundreds Grids

The video tutorial explains decimal multiplication using hundreds grids. It covers multiplying a decimal by a whole number and a decimal by another decimal. The teacher demonstrates examples using grids to visually represent the multiplication process and checks the results using the standard algorithm. The video aims to help students understand decimal multiplication through visual models and standard methods.
