Subtracting Decimals with a Hundredths Grid

The video tutorial explains subtraction using a hundredths grid. It starts by introducing the concept of subtraction with four tenths, which is equivalent to forty hundredths. The instructor demonstrates how to fill the grid with this value. Then, two tenths are subtracted, followed by fifteen hundredths, showing the step-by-step process on the grid. The tutorial concludes with the final result of the subtraction, emphasizing the understanding of the subtraction process using visual aids.
