Pre-Algebra 04 - Whole Numbers, Integers, and the Number Line

The video tutorial by Professor Von Schmohawk at Why U explores the evolution of numbers, starting with natural numbers and their limitations, leading to the inclusion of zero to form whole numbers. It introduces the concept of identity elements in mathematics, such as the additive and multiplicative identities. The tutorial then visualizes numbers on a number line, explaining operations like addition and subtraction. It further expands the number system to include integers, discussing their properties and the concept of negative numbers, with real-world examples illustrating their significance.
