Understanding Multiplication and Division

This video tutorial covers a mathematics lesson for grade 5 students, focusing on multiplication and division of whole numbers up to 100,000. The lesson uses real-life scenarios involving a student named Yohana to illustrate these concepts. The first problem involves calculating the total amount of money Yohana receives from angpao during the Chinese New Year, while the second problem involves dividing a sum of money equally among children. The video concludes with a summary of the key points discussed.
