Whole Number Operations and Basic Arithmetic

This video by Mr. J provides a quick review of basic arithmetic operations with whole numbers, including addition, subtraction, multiplication, and division. Each section covers the essential steps and techniques, such as lining up numbers for addition and subtraction, using partial products for multiplication, and estimating for division. The video is designed as a refresher, with links to more detailed explanations available in the description.
