Whole Numbers: Operations and Properties

The video tutorial explains the properties of whole numbers under various arithmetic operations. It covers addition, subtraction, multiplication, and division, highlighting that whole numbers are closed under addition and multiplication but not under subtraction and division. The video also discusses the concept of undefined results when dividing by zero.
