Understanding Division Involving Zero

This video tutorial explains the concept of division involving zero using area models. It begins with a review of dividing eight by four, illustrating how rectangles can represent division. The tutorial then explores zero divided by four, showing that it results in zero, and explains why four divided by zero is undefined. The use of area models helps clarify these mathematical concepts.
