Adding Decimals Using a (10x10) Grid

The video tutorial explains how to represent and add decimals using a 10x10 grid. It begins by introducing the concept of using the grid to represent decimals, where each square represents one hundredth. The tutorial then demonstrates how to represent 24 hundredths and 58 hundredths on the grid by shading columns and squares. Finally, it calculates the total shaded area to show that 24 hundredths plus 58 hundredths equals 82 hundredths, reinforcing the concept of decimal addition using visual aids.
